[Q] Nvidia Denver Dual Core a setback - Nexus 9 Q&A, Help & Troubleshooting

I have read many specs showing the Denver having a massive CPU performance.
However, all of these are "Single Core" performances @3Ghz.
Multi core performance, is just, on par with quad core benchmarks.
However, when I am multitasking, is this going to be a serious issue, with all the overhead of context switching and stuff, especially since Nexus 9 is clocking this at 2.3Ghz (a massive 25% reduction from benchmarks)? I mean, quad core is quad core. Single CPU performance can only do so much.

From the looks of things it'll pull it's weight for multi core loads as well. The only thing that out performs it on multi core workloads is the Galaxy Note 4, and even then it's not by much.

Thanks. This should be enough to do pretty much anything seamlessly. I am primarily interested in graphics performance, one reason being the QHD screen, and that is mind blowing anyway.
Don't know why they removed 4K recording, as the CPU and GPU can handle it.

There might be a mod for it in the very near future? 4k

QXGA (2048 x 1536), not QHD (2560x1440). Close enough though, only about a half million pixels difference between the two.

Multicore performance doesn't matter much in real world scenarios.

Thanks. You are indeed correct. I was just looking at Nexus 6 and note 4 and "missed" it. Besides, that half a million pixel difference (actually 540672), is only 17.19%, so The Tegra K1 won't notice it anyway
And now I'm unsure. Why would they put a lower resolution in N9, when they are putting QHD in N6?

same with ram.

Maybe the price would be to high, like it already is?

It is really impressive to see a dual core getting the same performance as a quad core in multi-threading tasks, shows just how powerful the cores are. I dont think it is a setback really since it isnt performing a lot worse, and single thread gets such a large boost. This is Nvidia's first every CPU core, and it is really impressive. I am sure we will see a quad core version next generation or so when they can make the processor on a smaller node.

Being that Android L doesn't appear to have multi-window or floating-window multi-tasking, I don't think the lack of a quad-core is a big issue. Many Macbook Airs and Surface Pros have been running dual-core forever (even current models), and you could argue that people do far more multi-tasking on those full desktop OS's than an Android tablet.
Also, related, Antutu benchmark of the N9 from the other thread - http://i.imgur.com/c6b57dT.jpg

More likely, they are trying to match it with Apple's iPad Air 2, which seems reasonable.
However, they probably should have gone with 1080p in N6. That is wayyy overpriced.
I would have preferred to get a QHD in N9 and QXGA in N6, which would have given N9 an edge.

I am actually waiting for an A8X vs N9 (Denver) benchmark as I read stuff like "they turn off graphics features on Android despite more powerful hardware".
If the above holds true though, I'll probably get N9.

iPhone 4S faster than Galaxy SII?

I picked up my Galaxy SII after seeing the disappointing specs on the iPhone 4S. But today I read preliminary benchmarks and it smokes the SII.
Sorry, unable to post a link yet.
How can a 800 mhz cpu beat the SII's 1.2 ghz processor?
I am confused. Am I missing something?

Because benchmarks don't mean jack ****.
Look at how Quadrant scores are all over the damned place with no correspondence to actual usability.
its all about the software. I expect some good gains when moving over to ICS.
Edit, corrected iPhone processor family name.
Trying to benchmark across different operating systems and hardware is not easy to accomplish, but I can tell you that an (Apple A5) A9 800 mhz duel core Samsung processor is not faster than (Exynos) A9 1.2 ghz duel core Samsung processor.
Yes both phones processors are made by Samsung

This is true but your wording is a bit confusing. An "Apple A5" processor is a dual core a9 processor with a powervr 543mp2 gpu. An A5 processor is an Arm core made for ultra low power. Basically both the apple a5 and the exynos processor have have the same processor architecture but there are many other factors that can influence performance like the GPU, memory, cache, decoders, ect. In this case i think the main discrepancy will be the software thats so different between the two.

I did not doubt that both processors were of the same type and architecture, but I did not realize that apple A5 was just an apple brand and that both processors were A9. Both are still Samsung family processor one clocked at 800 mhz one clocked at 1.2 GHz
Thank you for the correction

The iPhone is probably utilizing the processor to it's full extent, while Gingerbread (and Android in general) does a terrible job of utilizing the power of the hardware.
ICS should see a nice performance increase on dual cores.
OP is probably refering to the benchmark for gaming. It's not the processor that lacks on GS2. If iPhone 4S does come with the same A5 as iPad2, its GPU will smoke Mali400 in GS2 in almost every benchmark test (in most benchmarks, it is twice as fast as Mali400). Just checkout the review of Internationl GS2 by Anandtech.com with benchmark comparison of GS2 vs iPad2 and other smartphones. It is not the Quadrant or Linkpack benchmark but rather the professional benchmarks measuring fill rates and triangle thoughputs etc.
Processor performance wise, it is probably a wash because both are based on the same ARM design.
Although I do agree that benchmarks are just benchmarks, I am still surprised.
Is it true that Gingerbread only utilizes one cpu? And will Ice Cream Sandwich utilize both?
And BTW, I am by no means an Apple fanboy. I had been waiting for this phone to come out to replace my dinosaur BB 9000, so I wouldn't have to get an iPhone and deal with iTunes.
iOS5 > gingerbread. Sad but true.
Hope ICS comes out soon. It seems to be on par from what I hear.

I think I saw the benchmark in question - it was a GPU-heavy benchmark for a workload that most users won't experience 99% of the time. (It was a GPU-bound OpenGL benchmark. The GPU of the iPhone 4S IS faster than ours for 3D work - but unless you do lots of 3D gaming, it's wasted. Also, 3D is kind of a waste on a 3.5" screen.)
Apple has an extremely long history of misleading the public with selective benchmarking. Back in the Pentium II or III days, they claimed one of their machines was twice as fast as an Intel machine clocked at least 50% higher. While I agree that MHz isn't everything, there's a limit to that. In that case, on a single Photoshop benchmark that was optimized for PowerPC by using AltiVec and running non-optimized on the Intel chip (despite an optimized MMX or SSE implementation being available), the Apple did better - and Apple used that to try and make users believe the machine was twice as fast for all workloads.

It is true.
I guess the benchmarking was for the javascript using safari browser. So it's apple vs oranges. Also completely 2 different OS. Let's run quadrant if it's available for iOS the see how it handles. In the mean time enjoy the best and fastest smartphone currently in the market no matter what other says.

It could be ten times faster than a GII, but it still has a 3.5" screen, and I-jail. My wife and kids have Iphone 4's and there is no way I would trade no matter how fast this new one is.

Except for the wife and kids part(I have neither) this. Very much this.
Just ran the SunSpider Javascript on CM7.1. Results seem to be quite a bit better than the ones I see posted on AnandTech. Obviously they were running the GS2 stock but I was surprised to see my numbers so low. Also did the GLBenchmark and while the Egypt was slower, the Pro was faster on CM7.1. Coin flip to me it seems...
Those are just plain synthetic benchmark, what does it mean for RL usage? not a damn thing.
You think all the fashionnista who's buying iphone 4s gonna care how fast their CPU are?

Are you high and drunk?? As far as I'm aware, iOS5 is just playing catch up to Android. There isn't one feature that they implemented that hasn't already been introduced in Android since the Froyo days.

Being that there are currently no EGL libs for anything except PowerVR SGX devices under ICS yet, and they're closed source and tightly dependent on the kernel there doesn't seem to be a huge point until the official updates start to hit for a range of devices.
Sure, Desire, HD, X10, N1 have ports of a sort at the moment, in fact there shouldn't be too many problems getting them working aside from the graphics drivers but they're just for fun with the framebuffer driver given how much of ICS' UI rendering is done with GPU acceleration in mind. You wouldn't want to use it day-to-day. The browser is surprisingly responsive on the Desire though (I'd say moreso than GB, despite the software rendering), as is the Market (the new one always lagged really badly for me on the Desire before) - glimmers of hope for ICS' eventual performance on older devices. The keyboard lags like you wouldn't believe though!
The Atrix should fly under 4.0.1 though, if it ever happens - bearing in mind the fact that the SGX 540 in the Galaxy Nexus is pretty much in a dead heat with Tegra 2's GPU, we've got a lower resolution screen, and can overclock past the its stock speeds.

So EGL = gpu driver? If thats the only setback, would it be possible to get an ICS rom with software rendering as a proof of concept, or are there other pieces missing?
GB/CM7 is pretty good on the Atrix, if we dont see ICS for a few months it doesn't hurt us in any way. I'd like to think most of us can be patient if we lack the skills to help.
I noticed the Captivate got a port of it too since i9000 ROMs and Cap ROMs are interchangeable. I thought its funny that it's running on the HD a Windows Mobile 6.5 phone lol. Let's all try to be patient and we will eventually see it.
Edit: not to mention I'm sure if it's not already it will soon be on iPhone too. It seems like iPhones always get the new Android versions kinda early. I'm not sweating it I love my Atrix in its current state.
According to anandtech, Tegra 2 support is essentially ready, so I think as long as nvidia releases the source for ics (libs?), someone will try to port it. Hell, I have a good 5 weeks during break, I might as well try then.

Actually, no, despite being a much older GPU, the SGX 540 found in the GNexus outpaces the Tegra 2 due to its higher clock rate by 7% or 45% depending on the GLBenchmark being run. Both GPU tests were done at 720p resolution. Also, you can't overclock the GPU, only the CPU.

Depends on the benchmark, yes - texture-heavy rendering tends to perform better on the 540 in the OMAP4460 thanks to it's dual channel memory controller and high clock (and that's probably the directly relevant part to UI rendering to be honest, though as I said - lower resolution screen ) but the Tegra 2 is quite substantially ahead in geometry-heavy rendering (and games on mobiles are starting to move that way now, following the desktop landscape over the past 5 years or so.) Averaged out, the performance of the two is very close.
Plus, as I said, the GPU in my phone is running at 400MHz which ought to even things out in the GLMark 720p tests somewhat even if they are biassed to one architecture or the other. While the GPU in OMAP4460 may overclock just as well from its stock 400MHz, I'm only really concerned that the phone can run as fast as a stock GNexus to maybe skip the next generation of mobile hardware and tide it over until Cortex A15-based SoCs on 28nm process start to emerge with stronger GPUs. I don't really think I'm CPU performance bound with a 1.4GHz dual-core A9 - and increasing the number of equivalent cores without a really substantial boost in GPU horesepower seems worthless right now, even if ICS takes better advantage of SMP (re: Disappointing early Tegra 3 benchmarks - although it does seem GLMark stacks the odds against NVidia GPUs more than other benchmarks?)

I would expect the Tegra to beat a nearly 5 year old GPU, but it only does so in triangle throughput. Tegra just uses a very poor architecture in general. Look at how little actual horsepower it can pull. The Tegra 3 gpu pulls 7.2GFLOPs @300mhz. The iPad GPU and the upcoming Adreno 225 both pull 19.2 GFLOPS at that same clockspeed. I honestly have no idea what the engineers are thinking over atNnvidia. It's almost as bad as AMD's latest bulldozer offerings. It's really more of Tegra's shortcomings than GLMark stacking the odds. PowerVR's offerings from 2007 are keeping up with a chip that debuted in 2010/2011. The Geforce just doesn't seem to scale very well at all on mobile platforms. But yea, all Nvidia did with Tegra 3 was slap in 2 extra cores, clocked them higher, threw in the sorely missed NEON instruction set, increased the SIMDs on the GPU by 50% (8 to 12), and then tacked on a 5th hidden core to help save power. Tegra 3 stayed with the 40nm process whereas every other SoC is dropping down to 28nm with some bringing in a brand new architecture as well.

I think you are not seeing the whole picture...
The Tegra 3 (Et-Al) is not just about its quad core implementation, remember that the GPU will offer 12 cores that will translate in performance not seeing as of yet on any other platform.
Benchmarks don't tell the whole story! Specially those benchmarking tools which are not Tegra 3 optimized yet.

LOL I ran all the iDroid ports on my iphone. Not one was even in alpha stage, I would not even count iDroid as a port since you cant use anything on it.

dual core vs quad core

So I've been lurking on the prime's forums for a while now and noticed the debate of whether the new qualcomm dual core will be better or the current tegra 3 that the prime has. Obviously if both were clocked the same then the tegra 3 would be better. Also I understand that the gpu of the tegra 3 is better. However, for normal user (surf web, play a movie, songs etc) isn't dual core at 1.5 ghz better in that an average user will rarely use more 2 cores? The way I understand it each core is able to handle 1 task so in order to activate the 3rd core you would have to have 3 things going on at the same time? Could someone please explain this to me?
First of all, the tegra 3 can go up to 1.6 ghz. Secondly, all 4 cores can be utilized by a multi threading app. Lastly, battery is great on tegra III due to teh companion core.

But the native clock for that qualcomm would be 1.5 meaning o/c can take it higher. Also doesn't being dual core compared to quad core give it an edge in battery? You do bring up a good point with the multi threading app. Also to clarify I am not standing up for the qualcomm chip or putting down the tegra 3 just trying to get things straight.
Thanks
Hey I'm the ....idiot aboard here....lol
But the tegra 3 has a companion core, being a fifth core, to take over when the tablet is not stressed. Thus saving the battery.
I am just repeating what I have read, I have no knowledge of how it all works. I guess that is how we can get better battery life.
Just trying to help the OP, maybe some one way smarter can chime in. Shouldn't be hard....lol
Quad core is better by far. On low level tasks, simple things, and screen off/deep sleep the companion core takes over. Meaning its running on a low powered single core. This companion core only has a Max of 500Mhz speed. So when in deep sleep or low level tasks, companion core alone is running everything at only 102mhz -500Mhz. Most of the time on the lower end. Therefore tegra3 has the better battery life since all it's low power level tasks are ran by a single low powered companion core. That's 1 low powered core compared to 2 high powered cores trying to save battery. Quad core better all around. We hsvent even begun real overclocking yet. The 1.6Ghz speed was already in the kernel. So if you rooted n using vipercontrol or ATP tweaks or virtuous rom, we can access those speeds at any time. Once we really start overclocking higher than 1.6Ghz we will have an even more superior advantage. Anyone knows 4 strong men are stronger than 2..lol. tegra3 and nvidia is the future. Tegra3 is just the chip that kicked down the door on an evolution of mobile chip SoC.

If you really want to learn the in and outs of tegra3, all the details, and how its better than any dual core, check out this thread I made. I have a whitepaper attachment in that thread you can download and read. Its made by nvidia themselves and goes into great detail on tegra3 by the people who created it, Nvidia. Check it out.

But the native clock for that qualcomm would be 1.5 meaning o/c can take it higher. Also doesn't being dual core compared to quad core give it an edge in battery? You do bring up a good point with the multi threading app. Also to clarify I am not standing up for the qualcomm chip or putting down the tegra 3 just trying to get things straight.
Thanks

The maximum clock speed isn't all that important, since during tasks like web browsing, watching videos & movies and listening to music you will never push the processor to its highest available clock speed anyway. All mobile devices will underclock their processors so that you rarely have unused clock cycles eating up battery life. So all things being relatively equal performance would be about the same between both tablets during these types of lightweight tasks.
If you have a lot of background processes running, then the quad-core system might have an edge in performance since theoretically different tasks can be pushed off to different processors. However this use case is rarely found in Android. You might have an app checking weather or syncing photos in the background, or you might have music playing while you web surf, but those are generally fairly lightweight tasks that usually won't test the processor performance of your device.
In tasks that will stress you processor, such as 3D gaming, then quad cores have a very large advantage over dual core systems, despite the slight difference in maximum clock speeds. In addition the Tegra 3 has a more powerful GPU than the new Qualcomm chip, which will definitely make a noticeable difference in gaming performance.
Now when it comes to ultra-low power tasks or when the tablet is on Standby, the Tegra 3 uses its "companion core" which has incredibly low power requirements, so it can continue to sync your email, twitter and weather updates for days (or weeks) while having very little impact on the Transformer Prime's battery.
So in short, the Tegra 3 is more likely to outperform the Qualcomm in situations where you actually need extra performance. In light tasks performance between the two should be about the same. Battery life is yet to be definitively determined, however the Tegra's 3 ultra-low power companion core should give it an edge when only doing light tasks or on standb.
Keep in mind, the Tegra 3 in the TF Prime has a maximum clock speed of 1300Mhz. One core has a maximum clock speed of 1400Mhz. If all things were equal, a difference of 100-200 Mhz n a 1Ghz+ processor is practically unnoticeable in daily usage.

At least that is what Nvidia would like you to think.
The Tegra 3 uses an older ARM core for it's quad core design while Qualcomm uses their own ARM instruction set compatible core for their Krait S4 design. For most current benchmarks the Qualcomm Krait S4 dual core seems to outpace the Tegra 3 by quite a large margin. And of course Krait will be expanded to quad core later this year.

There's already another thread on what you just mentioned and the Krait claims were easily shot down. Tegra3 still a better chip overall. Plus krait gpu was subpar to tegra3. We have more links and stuff in other thread showing Prime still right up there

As unlikely as that seems considering the slower cores that Nvidia uses, links to real benchmarks ( not self serving white papers ) would be appreciated. I have glanced at your Tegra3 thread but have not read it all the way through after I saw that it seemed to depend a lot on a white paper and not real comparison tests. It is true that the current GPU the Krait uses is not as fast as the one in the Tegra 3, but graphics is only one element of overall performance. The only benchmarks that I have seen Tegra beat out Krait on were benchmarks that emphasized more than two threads, and then not by much.

Thanks, Will do. Gotta run for a doctor appointment right now though.
I frankly think the power savings with the fifth core is mostly hype. According to many battery tests I've read online and my own experiences with my Prime, it doesn't get much different battery life from dual core tablets.
Quad core is better for future but problem for backwards compatibility... it's definitely good for tablet.

No dual core android tablet battery last longer than an ipad1. My prime easily outlasts my Ipad in battery life. The battery hype is real. Tons of people here seeing 9-11hrs+ on a single charge with moderate to semi heavy use on balanced mode. Even longer on power savings mode.

I think if Krait were to come out with quad core then it would beat out tegra 3 otherwise no. Also they are supposed to improve the chip with updated gpu to 3.xx in future releases. Also benchmarks have been proven to be wrong in the past so who knows? Not like benchmarks can determine real life performance, nor does the average user need that much power.
Companion core really does work

Strange, we just started uni here (Australia) and I've been using my prime all day, showing it off to friends (to their absolute amazement!) showing off glowball, camera effects with eyes, mouth etc. 2 hours of lecture typing, gaming on the train, watched a few videos and an episode of community played music on speaker for about 40 mins, webbrowsed etc etc started using at lightly at 9 am (only properly at say 1:30 pm) and it's 10:00pm now and GET THIS!!:
72% battery on tablet and 41% on the dock. It's just crazy man. No joke, it just keeps going, I can't help but admit the power saving must be real :/
Edit: Whoops, I quoted the wrong guy, but you get the idea.
That's what I'm saying. Battery life on prime is great. Add a dock n battery life is sick!
I do agree a quad core variant of krait or S4 will give tegra3 a really good battle. Regardless I'm more than satisfied with power of tegra3. I'm not the type as soon as i see a newer or higher spec tab, ill feel like mines is useless or outdated. With have developement going hard now for this device. Just wait till the 1.8-2ghz+ overclock roms n kernels drop. Then we would even give new quad core higher speed chips a good run.
Above all of that, Android needs to developement more apps to take advantage of the more powerful chips like tegra3 and those that's upcoming. Software is still trying to catch up to hardware spec. Android apps haven't even all been made yet to take advantage of tegra2 power..yet lol. With nvidia/tegra3 we have advantage because developers are encouraged to make apps n games to take advantage of tegra3 power.
Regardless we all Android. Need to focus more on the bigger enemy, apple n IOS

LTE & Dual Core/Quad Core chipsets

Quick question. I was reading an article about the HTC One X. It supposedly will come with a tegra 3 quad core processor but not in the US. We will get a Snapdragon S4 dual core so it can have LTE.
Does this mean we are stuck with dual core Snapdragon's in the future? Why can't they add LTE to the Tegra 3? It seems like a pretty big difference in processors. If I were planning on getting the One X I would be pretty disappointed knowing there is a more powerful phone out there. Why do we get gypped compared to overseas??
I guess I'm just saying that there are a ton of different chips out there and I don't wanna be stuck with Snapdragon's forever just to have LTE.

This. People have this notion that just because a CPU has more cores that it is going to perform better. That isn't always the case. It has to do with architecture.

Cores do help in more simultaneous tasks taking place though, no? So if you're running multiple tasks, the Tegra can handle more of a load than the S4 would be able to?

Sure, but as anandtech said:
"Qualcomm's strengths are clearly single/lightly threaded CPU performance as Krait is able to offer some significant steps forward in that department. Tegra 3 can hold onto an advantage in heavily threaded apps, but I'm not entirely convinced that in phones we'll see a lot of that."
Basically, sure, yeah, there's a theoretical advantage, but what are you doing on your phone that necessitates four cores? And even then, the S4 doesn't perform significantly better or worse on multithreaded tests than the Tegra3.
By the time you need a new phone, there'll be quad-core Qualcomm processors. I wouldn't worry, at all.

It's like putting two engines in your car. It has the *potential* to go really fast, but unless your car is built to use two engines, it's not going to make any difference. Not the best example, I know. But it's simple.
As per the OP, we just don't have compatible LTE/Tegra3 combinations yet. Very bluntly, our LTE stuff sucks. (Which is why Apple passed on it with the 4S) Eventually, there will be an LTE modem that works with a quad-core chip, it's just not there right now. Like everyone else has said, in real world performance, you won't notice it anyway.
Nvidia is working on a Tegra 3 chipset with LTE built in I think I read.
Regardless, S4 is still a beast of a chip.
im glad the htc one isn't coming to verizon. it's stuff like this that makes our rezound outdated way before it's time. no one really "needs" a quad in a cell phone and im glad there isn't alot of quad core devices coming this year. both ces & mobile world congress were a big disappointment as far as im concerned.
IMO, the S4 dual core is an awesome chip. I am very skeptical about quad core battery performance. Due to technical advancements maybe they are superior. We will see soon enough.
Sent from my ADR6425LVW using xda premium
still no good with limited. if you're not doing heavy multithreaded work you won't see much difference plus 4 cores means more battery consumption vs dual
Tegra = fail. The market is doing a good job with over hyping dual core and quad core. Some people think it's almost necessary to have dual/quad socs , when other platforms like w7 run just fine on a single core.
isn't the second core on resound usually asleep a lot of the time unless needed? now you can have 3 cores taking a nap
lol.
Sent from my ADR6425LVW using xda premium
most dual core phones only use the second core as a back-up or for HDMI only
thus making it pointless to have quad-core phones at the moment i ran everything just fine on my Thunderbolt which was single core and it out performed my stock rezound.. and yes quad core i presume would be a battery drainer cuz dual cores don't really even have that good of battery life and single cores r the same
and snapdragon has quadcores already and they r in the midst of working on 8core chipsets but that wont be out till late 2013 early mid 2014 so stick with what u have
all good things take time

Comparing The Tegra 3 and the Snapdragon S4 is like comparing the AMD Bulldozer chips with the current Intel chips. They put more cores on a die and call it "The Fastest" but when the benchmarks start showing up it falls short of a lower end, more efficient chips. In theory more cores = more power, but in reality architectural is everything. All the hype from people being like "MOAR COREZ OMG FASTER" is a bunch of bull...

CES and MWC are just teasers anyways. Did you see the Rezound, Nexus, Razr, Razr Maxx, Transformer Prime, Galaxy Note, etc at those events last year? Nope, you saw the Bionic which 7 months later was a disastrophy, lol.
Did veruzon say they weren't getting the one x? I know there is a new verizon htc phone on the road map.
I'm curious about the snapdragon s4 just because it has lte integrated.

Well the One X has the same processor as my laptop 1.5 gh quad core. The only thing I think my computer really needs the quad cores for is intense games especially my wii emulator, which probably could run on One X since it has the same processor as my computer.

It's also pretty dependent on the GPU. Not sure what kind of graphics card your laptop has, but that has a pretty substantial effect on gaming.
The One X has a great dedicated GPU, but it's still a phone. Not sure if it can really match up to an actual computer's graphics card, but I've been wrong before.

Processor on the one x+

Will the tegra 3+ processor affect performance in any way? And what are its drawbacks as compared to snapdragon? Also does it have any advantages over the snapdragon?
Not really. The tegra 3 to be truthful is one of thebworst SOCs on the market. The krait s4/s4 pro both out perform it in every aspect. Be it standard voltage, dye leakage (smaller transistors 28nm, as opposed to t3's 40nm), performance at similar clock speeds (float point, multitasking, etc). I feel like nvidia really has no clue what theyre doing looking at the architecture for the tegra 3. TI's OMAP crushes the krait s4, and the exynos chipsets usually are on top of that. The only real drawback to having an exynos chipaet is the lack lf source documentation on sammys part which makes development difficult. But with all thats been going on regarding that it looks like thats about to change. Exynos with documentation is as good as it gets since youre getting a powerhouse CPU and GPu. The t3 has got an okay gpu at best. Sorry to burst your bubble :/ just stating facts

For me being USA ATT user would it then be best to choose the HTC ONE DLX instead of the ONE X+ due to the processors? Well neither are out yet so who knows if the US version processors will be any different. Just thinking with a 5" screen i'll need a back pack to carry it around, lol. Coming from an Iphone 4 3.5" screen to a possible X+ 4.7" screen is a huge jump in itself. Just can't stick with Apple after the huge let down of the Iphone 5 so making the switch as soon as these phones come out. New to all this stuff but had no idea Tegra 3 really that bad? Videos of the device look smooth and gameplay?

A lot of pages, over 930, but worth the time to read to understand the Tegra3 chip and what it is capable of as well as some info regarding the S4. The second thread has 60+ pages and is concerning gaming on the HOX. Well worth the time to read and see what all had to be done to get the full potential of the Tegra3. You also have to evaluate your choices this way. The Tegra3 is built with gaming in mind. The S4Pro is built with all around performance in mind.
