Actually, I think its the bogomips.

But the AnTuTu Benchmark system info shows the correct stuff. My guess? The actual tester hasn't been updated as frequently as the Benchmark.
If we got that high of a clock, especially with all 4 cores, our Tegra 3's would burn up in like two seconds lol

That's only about 400MHz more than what it's running now, if you unlocked the 1.6GHz setting. I've seen speculation that we might be able to hit 2.0, but it's just that; speculation. I'm hoping it'll become a reality

I know, but that's the point I'm making. 5 minutes running all 4 cores at 1.6 GHz had my Prime at 42 degrees Celsius! 46.2 degrees is when I have my devices all but shut down to about 200 MHz... Like one or two minutes, all 4 cores, at 2.0 GHz, I don't see being actually usable.
Awesome for quick benchmarking? Yes. Awesome when utilized in Power Saving mode and using 2 or 3 cores? Sure.
Usable for gaming with all 4 cores? Hell no lol the Prime would melt IMO
P.s. I personally think we'll top out on the best Primes at about 2.2/2.3, with many users incapable of going past 1.8/1.9 without reboots and freezes and such. Just my own speculation, but the dev's shall show us.

Wow mine never gets that hot. Or even hot at all, really. Which governor did you have it set to? I always have mine set to 102MHz-1.6GHz with the interactive governor, and in performance mode, of course.
That's a good estimate for max clock speeds, I'd say. Can't wait to find out what the highest will be though!

I realize it's not realistic, things aren't going to run that way, but that's strictly 1.6 GHz for about five straight minutes.

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.

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!

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.

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.

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.

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...

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.

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.

I have seen them hit around 6 with liquid nitrogen cooling But I think he means over clocking the CPU. Personally I prolly won't go higher than 2 because I don't want to burn it. The computer I'm on right now has a first gen i5 lynnfield and I have it clocked at 4.2 with a Corsair H80 cooling it So much awesome is done by this processor now
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.

That's why you OC/UV Under volt it and Over clock it Great battery and max speed
Had that on my OG Droid and the battery life was better than stock while it was OCed

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.

On this that's extremely true but my OG Droid, and my current Phone (LG Revolution), over clocking gained me a lot.

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.

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.

.... So much overclock .... So little.... Mind Blown
For later tests, it the backplate is a heatsink for the CPU, then we could make a stand that acts like a heasink

I'm calling major BS on 5ghz. I doubt we will see anything much higher than 2 Ghz.

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?

Please reread the quoted text.
I have used the cpu5.sh script to overclock the prime to 1.6Ghz, and benchmark shows a good improvement. I started streaming a 720P movie, mkv format, and everything played perfect but after only 5minutes the whole aluminum frame started to heat up noticeably . So I suggest waiting for some tested overclocked rom's before overclocking to be sure you don't blow it up.
You cant say it is the CPU tweak.
1.5 & 1.6 are built into this CPU. So, technically, your not "over clocking" as your not taking this chip beyond it's design spec. It is a 1.6 capable chip.
Moto did the same thing in the first Droid. They sent the phone out "under clocked" and then later did an update and gave users a claimed speed boost, but all they did was ope up the chip to it's full capable speed & sold it as a speed improvement. That is all that has been done here, we just beat Asus to it.

You're looking at it way to simple. The fact that the tegra3 chip is capable of running at higher speed, does not mean that in the Prime it is designed to do so.
Not saying you can't run at those speeds, but at extreme conditions (warm weather) , it could be a problem.
Yeah, I don't buy into that the "Prime is not designed to" argument nor that it is the proven issue here for what I said and given the CPU tweak he is talking about does not ramp all cores so I can't see an issue that would cause one to fret... but we can agree to disagree.
What the OP should have done was use CPU Spy and look and see for how long and IF he was even using 1.5 or 1.6 speeds.
Hey - I do think we need to be careful using these tweaks and things should be watched, but give the chip is 1.6 capable, I fully believe the Prime and the cpu's can take it just fine. And either way, this is not "over clocking" technically speaking.
I would imagine (could be wrong) that this chip has overheat and quite possibly overvolt protection. Almost every chip in the last 6-8 years has had this. I remeber turning my athlon x2 on with no heatsink and it actually stayed on for about 10 minutes before turning off. Even at 1.3-1.4 it can overheat. Infact the small overclock will be minimal on heat gain until additional voltage is applied. I would be suprised.if this overclock heated this chip up more than 5 c vs stock.

IT DOES. Viperboy already confirmed this while looking around in the kernel or whatever. He posted that response in his thread in developement section. IT HAS a failsafe mechanism. I would love to know more details about it though.
PLUS what op said could be said about stock also. THE PRIME BACKPLATE GETS hot in regular performance mode. PLUS I've ran the "Real True" Overclocking. That's the combination of viperboy control mod n system tuner where all 4 cores are maxed out to 1.6Ghz. VIPERBOY control mod alone doesn't do that. PRIME runs fine n does get hot sometimes. It depends on what you doing. PLUS its always good to have a battery temperature widget so you always see the temp. IF CPU is working like crazy. You will see the battery temp go up alot. PRIME was actually designed with 1.6ghz in mind. THats why its part of the kernel. ALL ASUS did was disable it for battery longevity purposes.
Regarding the 1.6Ghz and cpuspy I had just reset the timer before I started streaming and afterwords it showed it had used 99% of the time at 1.6Ghz

Guys, look up "speed binning". Not every CPU is capable of max speed.

I read it. Long story short, Tegra3 can easily handle it. Its all about money. WHY would Asus/Nvidia release its first quad core device already maxed out? They want people to be more hyped up down the road when they easily enable the 1.6ghz on future devices, which will have the exact same tegra3 chip in them. Prime was their testing device for future speed increases down the road on future devices. Another reason theybdidnt enable it was because tl promote battery longevity. IF IT wasn't possible or supported or tested already, it wouldn't be in the kernel for us to easily enable it with root access.
If speed binning was an issue most people would need additional voltage to get to 1.6ghz. While this may be the case i in my experiences (HUGE PC overclocker) dont believe this to be the case. I have personally achieved a 1.8 to 3.4ghz overclock on -25c temps. So i have a bit of experience.

I posted this in another thread, but the Lenovo tablet running the Tegra 3, shown at CES, is being advertised as running at 1.6ghz.
No worries about running at that speed. Once the bootloader is opened up, I'd feel perfectly fine running at 2.0ghz myself.

So, now we have phones with quad core processors clocked at higher than the transformer 300, are they more powerful than tablets or is there something I'm missing?

Yes and no. True, they are clocked higher but, the internal processor is exactly the same in terms of speed and power. The RAM is also the same (1GB) except for that new LG phone which has 2 and is coming out in some Asian country later this year.
Also quadrant means nothing, were getting to the point where lower quadrants may mean better devices, let me explain.
A GOOD processor setup will clock down when in low power mode and when there is a high demand clock up to deal with it. Quadrant does not always throw enough weight to kickstart that high performance mode in all setups, so sometimes it tests lower than it should.
You also have to remember that quadrant tests IO of everything. If you have a better processor but, say, slower memory, you will test LOWER on quadrant even tho you have a better processor. If someone with, say a Galaxy S I9000 has an uber C10 micro SD and has the system loaded on that the IO for that system will be very high and even tho its only a 1ghz phone it could, in theory, quadrant higher than the TF201.
This is why i hate quadrant tests, they are flawed and i have seen roms that are meant to test high on quadrant and nothing else, and believe me for every day use they are SLOW.
Rest assured at this point theres only really one major quad core mobile processor. The 201 has it. The 300 has a lower clocked version of the same chip. The 700 is going to have a higher clocked version of the same chip. From a PROCESSOR standpoint, they are virtually identical.
Now when you say powerful, the galaxy S 3 (rumored) will definately have the potential to one up the prime. Usually samsung goes for lower res screens so the GPU doesnt have to work as hard, they have a customized chip so the processor may be slightly higher, and when factoring in other things (USB OTG, MHL abilities, Camera resolutions, etc.) it MAY be considered more powerful.
For now, tho, the prime is one of the top dogs. Maybe not THE top dog, but definitely a contender. Just remember: Theres always a bigger fish.
I concur with you fine sir.
These quadrant scores comparing processors should be ran to benchmark just the processor not everything else. That would at least give you comparable results.
