How high do you think we can clock the processors on the EVO 3D? I recall they are 1.5 ghz chips underclocked to conserve battery life. Think these can hit that magical 2.0? Or at least 1.8?
I could see maybe 1.6 but honestly nothing over 1.4ghz is worth it... (batter>speed)
And nothing currently requires anything over 1.2ghz or 1.5ghz for that matter, other than peoples e-penis.
Id like to see a 1.4ghz uv kernel over 1.8ghz 1 hour battery killer but I will use and test all of them

Well that's your opinion. I highly doubt a overclocking the processor to 1.8 would bring the phone down to one hour of battery life. It's not like it would be constantly running at that speed. I would prefer speed over battery life as I charge my phone every night and have plenty left over even overclocked to almost 1.3 on my EVO.

I think this is less about practicality and more about pushing our phone to the limits. overclocking on an already fast enough processor on a device which runs for the most part on battery, is not needed. however it is fun and nice to see the benchmarks soar.
I say 1.8ghz-2ghz
If they're anything like the EVO 4G, then it wont be a very high overclock
But assuming all are capable of 1.5 GHz, then it would be at least a 400-450 MHz overclock!

Again for e-penis and bragging rights on benchmarks nothing more...
As for saying 1.8 oc would kill it in a hour I was joking...
And I bet dollars to donuts you don't see a change in "speed" past 1.6ghz other than a hot battery.
Ginger bread can't fully optimize dual cores it does the job but untill a new os is out
no point ruining a battery for "speed" you won't see

While performance is key, I'd say this phone is well above the bar of expectations for most Android Apps at the current time. I'm more interested in squeezing the most battery life I possibly can via Underclocking. It will be nice to see how far this can be pushed with Two Cores to spread the workload across.

I'd bet that the chips in these phones will be those that were unstable at 1.5 ghz. That's how chip makers do these things. They make them all the same, then those with unstable silicon are sold as a lower clock speed. Not sure I'd expect over 1.5 and that might require higher voltage. Hope I'm wrong. We'll see I guess.

OK, a little less lazy right now. But simply the way that manufactures choose the speeds for processors is actually simple. In the case of the 3D it IS underclocked. The processor is an asynchronous dual core with clock speeds initially set at 1.5 by Qualcom and is used in Qualcom's phone they produce for developers. It is underclocked by HTC because of battery problems listed from the 4G and the unnecessary need of 1.5GHz in a F*ing phone. Manufactures for the most part do not underclock the CPU. The reason it is set at the level it is, is because it is most stable, efficient and meets the heat extraction needs (People forget CPUs are just circuits and produce heat with more voltage). OK lets back this up shall we. OK.
That is why I'm too lazy to post thing, I have to search up a link cause most of this is my general knowledge. Anyways, the QSD8650 found in the EVO 4G is clocked at 1GHz and has been posted to a stable 1.3GHz I believe by a recent post. Now the MSM8660 is posted to be a 1.5GHz CPU, so its overclocking potential is more near 2GHz but I would suspect it to get a little warm(sweaty palms anyone?) and I wouldn't know how stable it would be either (I don't know phones the best). Why is it underclocked? Because people kept *****ing at how much battery the EVO used and as technology improves so does the efficiency of CPUs so they go with the most recent and just underclock it. I've seen a comparison graph somewhere by Qualcom but I spent about 10minutes looking for it and couldn't find it but it was really nifty. If someone finds it plz post it, it shows the energy vs Clock speed and it is very cool.
Anyways, to respond to whoever said that the 1.5GHz is the max and that all manufacturers underclock the CPU based upon the silicon is WRONG, wrong WrOnG and Rong/wong (Im sorry I dont remember the exact response). Anyways, its the heat extraction and the silicon hurts it because it doesn't let all the heat through, which is one of the reason your PS3 may have yellow lighted on you(Yes its because of the CPU disconnecting from the Motherboard, but why do you think this extra heat was generated?).
Sorry this is so long and I got distracted a few times while writing it so it I messed up or something doesn't make sense I apologize but being lazy is really a pain in the ass.

That would be the case if this wasn't an MSM 8660. You're thinking like when AMD makes chips for the HD 6970 and some are found not to be stable at 880 mhz so they bin it to use in the HD 6950 which runs at 800 mhz. These are actually sold as two separate products. In the case of the processor in the Evo it's an MSM 8660 which is sold by qualcomm to be run at speeds as high as 1.5 ghz. If they wanted to sell chips binned for lower speeds they'd have to sell it as a different model since it wouldn't be capable of the 1.5hz.

toxic and donatom,
Your explanations make perfect sense. So I hope to be wrong. Does qualcomm sell a processor with that same architecture and a lower clock advertised?
Just seems like they're not gonna throw them away if they are stable and 1.2 or 1.4 but less stable at 1.5+. The 3vo seems like a good way for them to unload those processors.

To my knowledge, if this happens it gets recycled. But.....if this happens a lot then they need to change their manufacturing process or that the technology isn't there yet. Like now we have the technology to do 64GB MicroSD, but why do it because most devices can only do 32GB. For the companies that do sell them, well....I don't have good words for them, I also don't know of this happening. I can understand that it could be useful for donations to universities or others that could use them for damn near free prices, but not resold even under a different name.

Well in the case of AMD with many of their chip lines they produce a higher end chip. The ones that don't fully pass the tests at the higher speed get sold as a different model with a lower clock and voltage.
I have the most experience with the HD 6970 and 6950. They both use the same GPU, but the ones in the 6950 didn't pass AMD's tests at higher speeds so they are set at a lower clock and voltage than the 6970 (they also have some shaders disbaled). They are sold as two different models even though they were made the exact same way with the same silicone. This is not new chip manufacturers have been doing this for a while.
Think of it this way I make 100k chips out of those 100k I'm going to have a percentage that can't perform at their top performance, so instead of throwing them away I make a different model and underclock it and still make money on the chips that didn't pass at the higher speed. Now sometimes I will sell more of the lower end model so I actually have to take some chips that probably would have passed as the higher end model and sell them at the lower end. In this case the user gets lucky and can unlock their chip to the performance of the higher priced model.
EDIT: What HTC is doing here is buying a 1.5ghz chip but purposely underclocking it to save battery, since they figured most users wouldn't see the .3 ghz difference but would see the difference in battery life. Again in video cards you see this but usually the other way around. A manufacturer such as Asus, gigabyte, whomever takes the best of their chips they bought and overclocks them because again some were made even better than the standards set by AMD or Nvidia.
I guess what I'm trying to say here is that ALL these chips should do 1.5 ghz stable without question, unless there isn't enough space inside for the cooling requirements at 1.5ghz (which I doubt), and most should easily go above 1.6.
Edit again since I just saw this post:

This is something that happens mostly in higher end processors because their tolerances at those speeds are less forgiving. No manufacturing process is perfect, you're going to have some that won't perform at those very high speeds, and recycling would cost more to the company and environment then simply selling them at lower speeds. These chips are not bad, and not defective, just found to not be stable at those highest speeds, but are perfectly fine at the speeds they are being sold at, so why throw them away. If they don't meet the standards at the lower speed then yes they would be recycled.
I have a question about the 3D's dual core that I'd like more clarification on the vague answers I'm getting by searching this site and google. So I've read that the core is asynchronous so basically meaning the second core doesn't do much work unless needed as others like the tegra 2 and exynos have both cores running or something similar to that, and that this is affecting the benchmark scores. I also read that one would basically double the score of the 3D to get a more accurate reading. Can anyone confirm or further explain this?
Yes, asynchronous is when something operates on another thread whereas the main thread is still available for operating. This allows for better performance in terms of managing tasks. Now just because it doesn't score high on a benchmark, it doesn't mean it is going to perform. Also this allows for better performance for the battery.
I haven't slept for the past 12 hours so if this doesn't help you, just let me know and I will fully elaborate on how the processor will operate on the phone. Now time for bed :'(
In short, asynchronous operation means that a process operates independently of other processes.
Think of transferring a file. A separate thread will utilized for doing so. You will then be able to do background things such as playing with the UI, such as Sense since you will be using the main thread. If anything were to happen to the transferring file (such as it failing), you will be able to cancel it because it is independent on another thread.
I hope this makes sense man, kind of tired. Now I'm really going to bed.

To be more specific by asynchronous they mean that each core can run at different clock speeds. Core 1 could be at 1.2 ghz while core 2 is at 200 mhz. Most multi core processors are synchronous meaning all the cores are running at the same speed.

I was also very curious to learn a little more about the async cores and how it differes from a standard "Always-On" dual core arctechiure.
Thh first page/video I found talks about the SnapDragon core specifically.
http://socialtimes.com/dual-core-snapdragon-processor-qualcomm-soundbytes_b49063
From what I've gathered, it comes down to using the second core and thus more power, only when needed. Minimizing voltage and heat to preserve battery life.
The following video goes into similar and slightly deeper detail about the processor specifically found in the EVO 3D. The demo is running a processor benchmark with a visual real time usage of the two cores. You can briefly see how the two cores are trading off the workload between each other. It was previously mentioned somewhere else on this forum, but I believe by seperating a workload between two chips, the chip will use less power across the two chips vs putting the same workload on a sinlge chip. I'm sure someone else will chime in with some additional detail. Also, after seeing some of these demos, I'm inclined to think that the processor found in the EVO 3D is actually stable at 1.5 but has been underclocked to 1.2 to conserve battery. Only time spent within our hands will tell.
Another demo of the MSM8660 and Adreno 220 GPU found in the EVO 3D. Its crazy to think we've come this far for mobile phone technology.
What occurred to me is how complex Community ROMs for such a device may become with the addition of Video Drivers that may continue to be upgraded and improved (think early Video Card tweaks for PC). Wondering how easy/difficult it will be to get our hands on them, possibly through extraction of updated stock ROMs.
EDIT: As far as benchmarks are concerned, I blame the inability of today's bench marking apps to consider async cores or properly utilize them during testing to factor the over all score. Because the current tests are most likely to be spread across cores which favors efficiency, the scores are going to be much lower than what the true power and performance of the chips can produce. I think of it as putting a horsepower governor on a Ferrari.
thanks for the explanation everyone
The best demonstration is in the first video posted, notice when Charbax looks at the monitor. There on the top right are the frequencies of the two cores, and you'll notice the both of them jumping around a lot, independent of the other. Using the cores "on-demand" only when needed ends up saving a lot of battery power, but doesn't give you any performance loss.

Actually I was thinking that not just the battery savings but there could be a performance gain. Think of this if the manufacturer knows they only have to clock one core up to speed when needed they can be more aggressive about their timings and have the core clock up faster than a normal dual core would since they know they don't have to clock up both processors when only one needs the full speed.
I wonder if the drop to 1.2 GHz also serves to keep heat under control. It might not just be battery savings, maybe the small case of a phone doesn't allow for proper cooling to hit 1.5 safely.
I'd love to see some confirmation that the asynchronous nature of this chipset is what's responsible for the seemingly lackluster benchmarking.

The "horrible" benchmark scores are simply due to the tests inability to consider async core performance. Wait till the tests are able to take this into consideration.

I went through all of your links, I didn't see anything that confirms that the benches are somehow affected by the asynchronous nature of the chipset. It's not that I don't believe you, I actually had that same theory when the benches first came out. I just don't have any proof or explanation of it. Do you have a link that provides more solid evidence that this is the case?
NVIDIA actually tells a different story (of course)
http://www.intomobile.com/2011/03/24/nvidia-tegra-2-outperforms-qualcomm-dualcore-1015/
AnandTech's article does explain some of the differences
http://www.anandtech.com/show/4144/...gra-2-review-the-first-dual-core-smartphone/4
It appears that Snapdragon (Scorpion) will excel in some tasks (FPU, non-bandwith constrained applications), but will fall short in others .
I'm pretty sure none of the benchmark apps have even been updated past the release of the sensation so yeah....How could they update the app to use the asynchronus processors the if the only phones to use them have only recently been released.

Hmm...
If a program such as Smart bench (which takes advantage of dual cores) is stressing both cores to 1.2ghz then regardless of if both cores are active or not the bench will be accurate.
I would rather NOT have asyncronus cores as there would be lag during frequency changes...
Ex:
2 cores running at 500mhz vs 1 core @ 1ghz and other not active.
The 2 cores will produce less heat and use less energy...

There dual, it would be better for them to run asynchronous. Not only that, but it is a phone so there will be no lag between frequency changing. 2 Cores running at 500mhz will perform better than 1 core at 1ghz.

This is something that the hardware needs to be capable of. Software can only do so much. As far as I've seen Tegra isn't capable of it.
I read the anandtech article and I came with conclusion that everyday task you might not see the difference between the two and while tegra2 might bench higher. The main thing people dont talk about is the GPU. Adreno 220 is a powerhouse GPU, it will probably stand strong when tegra 3 comes out.

Andreno 220 is a horrible GPU. AT BEST it is equal to the GPU in the Original SGS.
The reason benches are so different is because Qualcomm has made NO improvements in the CPU. Desire HD CPU is the same as Sensations. While... SGS2 + Tegra have IMPROVED CPUs.

I remember reading a few months ago on a forum that the tegra 3 could reach 5ghz properly cooled, like a desktop cpu. I'm not too familiar with the Arm design so I do not know if this is true or not. I could see 3ghz but 5 is pushing it.
Also what do you think our overclocks and going to be when some devs get their hands on some kernels?

anywhere from 1.8-2Ghz for everyday usage, I'm hoping. maybe even higher but heat will be an issue as there's no fans to cool down processors. as far as that 5ghz thing, lol, it wouldn't be practical on a tablet. any of those super overclocks like on Bulldozer is just for show. not for practical use. they do it just to show it can be done. quad cores clock at 5Ghz would melt almost instantly..lmfao without some super impractical cooling method.
we will see a very nice overclocking jump. Stay tuned
Major gaming pcs can't make it to 5ghz. I've personally neve seen a cpu faster then 4.5ghz.
But in answer to your question 4 out of the 5 cores can reach 1.3ghz while then other can reach 1.4ghz.

We should be able to get all 5 to run at once unless it's a hardware restriction which couldn't be possible....
But idk if the processor of the prime it's connected to the aluminum backplate if it is I think we could get it to about 3GHz because the aluminum would be a big heat sink for it

Big heat sink yes but I would leave it there for very long. Soon the heat sink will turn VERY hot
My question is....Why bother OC (other than Yay! I can go Mhz ZooM!!...which can be fun)? But from a practical standpoint, there isn't anything out there, short of SW video decoding, that taxes the prime even at stock clocks...all you would do is run down your battery faster.
Now, undervolting, that's some useful stuff. Just me though.

Why not leave the speed where it is and just undervolt further and save even more battery power for the same performance? Again, you lose nothing but gain battery life.

That's the thing. For a device that struggles with some functions, an OC can do wonders (saw a nice improvement with my DInc and newer ROMs). But, in our case, the Prime runs everything you throw at it (aside from SW decoding) and it runs it without issue. So the gain from OC would be minimal when compared to possibly hour(s) of battery life gained through UV.
Now, later down the road, when new flashy things come out and the Prime starts to show its age....OC would definitely be of use.
Just my 2 cents.

Now, later down the road, when new flashy things come out and the Prime starts to show its age....OC would definitely be of use.
Just my 2 cents.

My i7 2600k is clocked at 5.2Ghz with just fan cooling. Not stock cooling though, stock cooling can be fine around 4.4-4.6ghz, due to the 32nm.
All the replys are focused on other cpus and why not to oc. I was just wondering how fast the tegra 3 could get if it had a proper cooler. I read 5ghz
Im not looking to oc my prime.

For later tests, it the backplate is a heatsink for the CPU, then we could make a stand that acts like a heasink

May I ask the following? :
What case/cooler do you have?
What voltages?
What temps on load?
And 4.4 - 4.6Ghz with the stock? Do you live in like 10 degrees Celsius ambient temps?

Hi guys! I was just checking out this thread in the Bionic section and they have an overclock without that many prerequisites. http://forum.xda-developers.com/showthread.php?t=1439013All we need is a rom with init.D support and tekahuna's "symsearch.ko" and "opptimizer.ko" modules. DroidTh3ory already has init.D support in this Bionic rom so if we could get that in our roms and just find a way to apply tekahuna's modules, our device may be able to get an overclock. Let me know what you guys think. I'm not sure if this is possible but I just want to try and help the Razr XDA community. Sorry if this is arbitrary and completely unapplicable to our device.
Intriguing - conveniently, there's a thread on enabling init.d support that just popped up: http://forum.xda-developers.com/showthread.php?t=1444545

Ha, funny. Given the RAZR is factory overclocked to 1.2ghz, I suppose it's to be expected. I've underclocked mine to the 1ghz the chip is rated for to save juice anyway.
Sent from my XT910 using xda premium
razr is not overclocked versus the other omap4430 1.0Ghz devices. Parts are tested in the fab, and the ones that can do 1.2g without crash andd without heating a lot are selled to be 1.2-compatible. Other are only 1.0G approved.
It means also that overclocking a 1.0 to 1.2 may cause crash and excessive heat.
For the 1.2G parts of the razr, don't expect great overclock. the omap is more enclosed than in bionic and is already reaching the thermal policy barriere that underclock it when intensive use. If you clock the opp-max over this frequency, you will hit the barrier faster and then finish by using lower opps most of time...

Interesting, so not all 4430s are born equal? Is there an actual variant thereof rated at 1.2, or do they actually test every single chip individually? I wasn't implying it's unstable at 1.2ghz, and hardware design does of course come into it as you've said, but as far as I'm aware it's the exact same chip that TI rated at 1.0.
Perhaps 'clocked higher than the chip has been generally rated for by its manufacturer' is a more accurate description than 'factory overclocked'?
Sent from my XT910 using xda premium
hmmm.. this is all very interesting. I feel like the OMAP 4430 in the Razr should be at more capable than 1.2ghz. My OG Droid ran stable at 1.275ghz and it had a 3430 which was built on the 65nm chip process vs the 45 in the Razr. I must say 1.25gz as a max is quite underwhelming. I was hoping this bad boy would at least be capable of 1.5ghz.

I feel the same, but reality is cruel
I read some time ago on a tech website that the 4460 (1.5) and the 4430 were made from the exact same materials. The only difference is that the ones that hit a very high threshold at 1.5 were stamped 1.5. 4460's. It's not that the 4430's couldn't do 1.5ghz , most could. Just that they couldn't run the benchmark all the way to the end the amount of times needed to qualify. Odds are that any 4430 could do 1.5ghz and probably stable. We will never stress it out the way these benchmarks do.
Does anybody know if this hack could actually work and allow us to overclock our device. I think we can worry about how far we can overclock after we get an actual overclock lol. Would anyone be able to rewrite the "symsearch.ko" and "opptimizer.ko" modules for our device so we can get an overclock on our device?

No rewriting necessary. It was developed on a RAZR. Available in the download section of the OPPtimizer site. 0.1 modules only adjust top frequency. 0.2 modules adjust top frequency and voltage. As stated on the homepage, symsearch.ko is the creation of Skrilax_CZ. In case you don't know who that is, he's the guy who got 2nd-init functioning for all of us.

Very true, and something to consider the when overclocking OMAP4 devices. They don't clock as high as some would think. Although, I'm not so sure that the lag that most people are describing is the thermal policy kicking in. I've noticed that this lag can be cleared up with additional voltage, and not exhibit the behavior of getting clamped down on by the thermal policy. For example, 1250MHz on my Droid RAZR at stock 1.375V, is flaky, bump the nominal voltage to 1.388V, and it holds, and up to 1280MHz without the lagging condition.
You appear to be well informed on this subject. Good points you raise!
Lol. I'm still trying to understand the fact that we had a overclock this entire time. I never found one on the forums but I guess we had the tools available all this time. I honestly didn't know we had one.

The kernel modules were only recently release. Some early testing was done in the LG Thrill community, as that was my original test device. Development was stalled a little by issues which I now realize were with the LG Thrill's kernel itself, rather than what I was doing. Got a RAZR on opening day and was able to come up with some code I feel comfortable releasing. It's only been available to the public for about a week now. I think some RAZR's will hit low 1300's... Don't know about much more.
Does this work? Is there a script for it? I have init.d support on stock from a bionic init.d cwr zip from droidrazr.com that works. What would a script look like to change voltages/ect?
Nevermind i see...its in the download section on link.
How do you run it or setup?
frostincredible on RootzWiki has created some flashable zip for Bionic, but they only work for my 0.1 modules that only support frequency manipulation. I have 0.2 modules that control voltage as well for Droid 3. You can open up his zip file and get an idea how to get things going with init.d... You can actually use his script, and just modify the echo line to say "echo 1122000000 1388000 > /proc/opptimizer", to send a voltage value, along with frequency.
http://rootzwiki.com/topic/14698-in...or-tekahunas-omap4-overclock-modules-1-10-12/
Page 2/3/4 on the official thread also has some info on init.d scripts for this.

This is not true. OMAP4460 and OMAP4430 are different chips. E.G. there are [email protected] and [email protected] the fact that the 2 products exists should be enough to say there are different.
I reckon they are not drastically different, most of the things are common.
So has anyone gained any noticable performance improvements with this? Also so it can 0nly be OC'd to 50mz more so 1.25ghz is the max? At this point is this mod developed enough for the razr for it to be a usable worth while tweak? Not dogging any devs just want to see if its worth it yet to start messing with this...
Also in the download section there is now this "MO_simple_spyder_1.5-beta-01.zip Milestone Overclock ported to Motorola Droid RAZR"
Whats that?
It depends on your particular processor, because every one is little bit different. I was able to run mine at 1300 MHz quite stable with stock voltage. But I don't see any need for more CPU power now, maybe someday
More interesting is undervolting to achieve longer battery life, which can be done with OPPtimizer too.

Has anyone had any good success with undervolting and battery life?
I was discussing something with anlther member on clock speeds and something was revealed. You know for the prime, normal performance top speeds are 1.4Ghz on a single core and 1.3Ghz on 4 cores. well Nvidia site that has spec on Tegra3 says something different now. It now states that the top speed is 1.5Ghz on a single core and 1.4Ghz on multiple cores.
Can people who are stock or rooted and haven't overclocked check this out? you can use CPU spy. put your prime in performance mode then use CPU spy to see what the top speed enabled actually is. don't report the speed not in use on the bottom. only look at the top speed actually in use and not in sleep. another way to tell is use an app like system tuner or system panel light and look at the Max speed the bar meter hits. it'll be fluctuating. CPU spy the best way.
I want to see if this new update might of actually increased the top speeds on stock devices. here is the link to look at the new tegra3 spec showing the increased speeds.
http://www.nvidia.com/object/tegra-3-processor.html
Ok buddy. Trying to work with ya here. I am completely stock, and not rooted.
Just installed CPU spy, wasnt sure if I needed to be rooted to run this, but it installed fine and seems to be working.
Anything you need me/us to run and get some clock speeds?

This is the specs: for the Tegra 3 chip, Asus chose not to use the 1.5 and clock it down to 1.4/1.3 to save battery life most likely!

it says unused states because although we do have those speeds in stock kernel, Asus has them disabled by default. only way to activate them is to root and use an app like EzOverclock or ATP tweaks App or vipermod to enable those overclocked speeds. the best one is Ezoverclock app. all you need to be is rooted. you install the app and you're instantly overclocked to top speed of 1.6Ghz. it changes the speeds on Asus quicksettings. after install, Performance mode will now be 1.6Ghz, balanced is 1.4Ghz and battery savings stays the same at 1Ghz. the other great thing about this app is that you can manually change what speed you want each power mode to be. after installing app, by default it'll be set to what I listed above. all those apps or programs are free and in developement section of prime.
edit: also rooting, unlocking device, and running a custom rom from developemnet section can overclock you also.
based on what people posted so far, it seems nvidia is just leasting the top speed capable on the chip, period. that top speed spec is actually for the new infinity pad. infinity pad will come stock with those top speeds of 1.5Ghz on single or 1.4Ghz on 4 cores.
My max is also at 1.4 GHz. Nothing above that has ever been reached.
Obviously I'm running stock.
Had also seen that they bump it to 1.5ghz..
And the specifications for HTC ONE X with Tegra 3 also shows the 1.5ghz..

Hope we helped with the discussion.
So at 1.6 are people noticing a big improvement in performance?
I guess the developed ROMS that we have available come with custom kernels? I see people pushing 1.8 and hoping for 2.0. How stable is such numbers, and are these modes raising temps and crushing battery life?

its not an updated tegra3 chip. exact same one in prime except on the software side they unlocked the higher speeds by default. out the box. with prime we already seeing those speeds and even higher being rooted and/or unlocked running custom roms or kernels. we even have achieved 1.8Ghz overclock now. really all you need is root to achieve 1.6Ghz. So technically prime already more powerful than these new tegra3 chips I'm future tablets, if rooted of course. Nvidia is skipping over the tegra3+ chip. they going straight tl Tegra4 which is expected to be keplar based. it will be on the 28 or 22nm die. meaning more power and more battery efficient. plus whatever bells n whistles nvidia adds tl it or tweaks it for. Tech sites expect Tegra4 to release q4 of this year. Tegra4 was already sent out to all major manufacturers back in December. so they testing it out now. Tegra4 will definitely change the market up again and something to be excited for.

yes, thanks for the quick tests from everyone. it was helpful in trying to figure out if new specs was included in new update.
yes 1.6Ghz gives it a very good boost in performance. thing is prime performs great on stock speeds also. but overclocking to 1.6Ghz will make it that much more faster. web pages will load alot faster. ui will be alot faster.
another trick to speed up your prime is to go into settings. then go into developer options. enable the force gpu rendering. I've been running this for a while and seen a big boost in performance and fluidity of the UI and other things. even in web browsing. you can also cut off the windows and transition animations. cutting those off will make everything nearly instant. like switching between apps, going from one screen to homescreen, etc...all of that will dramatically make your prime feel faster. all transitions will be instant instead of slight pause or gradual transition. screens will instantly pop to the next.

Or to improve yields; this is the first Tegra 3 product ever. I'm sure there were fabrication teething issues.
I thought those were newer revision/step of the same Tegra3 chip. ARM recently started offering a "Processor Optimization Pack" for A9s.

Thanks for the info on overclocking. We had talked about it before when I first say the higher speeds (disabled) and we talked about battery life - Good if you only run overclock for games & stuff, if I recall correctly. I have wanted to overclock for some time, but have been resistant to leaving it oc'd. What is the best way to toggle the OC on and off, vs. removing the app: Should I just run balanced for most use, then flip to performance for gaming, etc?
EDIT: Also if Nvidia is stating those are the top speed capabilities, does that dash hopes for craking these up to 1.7 / 1.8 and beyond? (To Asus Eee Pad Infinity... And beyond!) If so, that kinda sucks, though the tablet is plenty fast as it stands... we all like to see how far we can take stuff though... It's our nature.

ACTUALLY the AT&T HTC One X with S4 snap dragon chip, release date just got pushed back toMay 6th. http://www.talkandroid.com/103253-a...idForums+(Android+News,+Rumours,+and+Updates)
A GOOD REASON for that could be because there were various reports a few weeks back that qualcomm was having manufacturing issues with the S4 snapdragon chip. Production had completely stopped for some reason. Some kind of manufacturing problem that was said to lead to most device announced having Snapdragon S4 chip being delayed. The source on manufacturing issue was posted in that thread. That was a couple or a few weeks back when I posted that. I think S4 chip hasn't been produced in any real bulk amount yet, especially with issues with their manufacturing process that caused S4 production to stop.
So the longer S4 chip gets delayed, the better it will be for Tegra3. It'll be that much longer Tegra3 holding superiority over other android chips. If the first S4 chip having tablet doesn't show till may or June at earliest, then Tegra3 would've secured top spot in Android for 6months. FOR a chip to be successful in mobile market it really only needs to be dominant for 4-6 months. This is based off of how fast the mobile tech industry is moving.
I ran a benchmark on Antutu and it showed a CPU frequency of 1600.. See attached.

the best and easiest overclocking method is simply installing EzOverclock app. all you have to be is rooted. as soon as you install it. you're instantly overclocked. your Asus power mode quicksettings are instantly changed also. immediately after install, your performance mode is 1.6Ghz, balanced is 1.4Ghz, and battery savings mode stays the same at 1Ghz. Now you can easily change any of those modes within the app if you choose. my setup is Performance 1.6Ghz, balanced is 1.2Ghz, and battery savings is 1Ghz. So I normally run on balanced mode(1.2Ghz). whenever I want to run on 1.6Ghz, I just press Asus quicksetting Performance mode. remember that when ever the tablet resets or powers off and on, it'll default to balanced mode(for me 1.2Ghz).
so this app makes it seemless and simple to overclock. you use the regular asus power modes like you always do. then the ability to changes the speeds of those modes of you choose is priceless.
I have been using EZoverclock since day 1 I got my Prime. Running Eco Mode at 1 GHz, Balanced at 1 GHz too and Performance to 1.6GHz.
I hate how the screen looks in eco mode, so im almost always in balanced @1ghz, so far i can play anything, even 1080p videos thru HDMI withouth lag, and still have great battery.
For heavier stuff, multi task and so on, then to super 1.6ghz mode it goes
