So we all know the Nexus S has a 1Ghz Cortex A8 Hummingbird CPU, which sounds unimpressive considering the Nexus One has a 1Ghz Snapdragon QSD 8250, but it's a known fact that clock speed often has little to do with actual computational power. Qualitative previews have said that the Nexus S "flies," but I'd like to see something more in the numbers. If anyone has a demo device, could you run a few benchmarks? Or perhaps comment on performance after quick opening/closing several computationally intensive applications?

1gb humingbird is fast as galaxy S and iphone 4. both which are like 30% or more faster then snapdragon
I think the key improvement is in graphics performance. Here is a comparison.

The S5PC11x (Hummingbird) has 2x the memory bandwidth of the MSM8250.
The MSM8250 gets about 2x the floating point performance of the S5PC11x.
I believe the SGX540 GPU in S5PC11x is on the whole a bit faster than the GPU in the 8250, but I don't have hard numbers on that in front of me. They're architecturally different GPUs and will have different strengths and weaknesses.
It's really hard to do a good apples to apples comparison of different SoCs -- memory interconnect, cache sizes, ARM architecture version, GPU, etc, etc all play into overall system performance.
Gingerbread, overall, tends to be faster than Froyo on the same hardware.
Not really too familiar with this stuff, but will the JIT compiler being optimized for snapdragon instruction set make a huge difference still? My Vibrant plays games way better than the MT4G (imo) but scores terribly on Linpack and is terribly slow at opening applications and things vs. the MT4G.
Read the post above you. Linpack is mainly a benchmark for numerical performance(floating point etc), where the Snapdragon chips are MUCH better.
But the Hummingbird(PowerVR) GPU is better than the Adreno GPU found in the Snapdragon line. That's why the gaming performance of your Vibrant is better than the MT4G.

Yup, just anecdotally, hummingbird is MUCH faster than snapdragon IMHO
galaxyS/NS SGX540= 90 million triangles/sec
HTC G2 Adreno 205 =44 million triangles/sec
Nexus one = Adreno 200 = 22 million triangles/sec
nexus S is running on the fastest GPU out now. And another good thing about running on power VR GPU is that iphone runs on one also so when lazy iphone porting happens you will have optimal performance running on that GPU than you would on Adreno
Ive noticed this especially on gameloft games
Trust me im on a vibrant and came from nexus one with out a doubt the nexus S GPU smokes nexus one GPU even out performance 2nd gen snapdragon
Hummingbird > all atm.
Orion will be the same.
Don't make pre-assumptions about the dual core chips.. Orion has good competition from the TI OMAPS line.. Qualcomm looks like they'll stay behind GPU wise though.
Plus the Sound Quality of the Hummingbird chip is awesome. MUCH better than the Snapdragon chips.
Also, you have to be cautious of manufacturer specs for GPU pixels/sec and triangles/sec -- the "box numbers" are always under optimal conditions and often not representative of real workloads.
For modern non-fixed-pipe GPUs (gl ES 2.x, etc) compute capabilities (how many shader ops / pixel/ etc you can get away with) factor in as well.
Depending on what your workload is like (geometry heavy? fill heavy? texture heavy? shader heavy?) you will see different strengths and weaknesses when comparing GPUs.
All that said, the SGX540 is indeed quite snappy.

I agree the sound chip is good in the NS, as is the GPU
I am sick of everyone thinking the upcoming dual-core devices will blow away tegra 2.
Tegra 2 vs Dual Core A5 (Ipad 2)
A lot of talk about Andntech OpenGL benchmark trumping Tegra 2, but what about Stockfish and Benchit Pi where A5 got slaughtered (PC Magazine)? With half the RAM and lower clock I don't see this thing smoking Tegra 2 in all benchmarks, or real life CPU situations.
Tegra 2 vs Exynos (Some Galaxy S2)
Lower benchmarks in Smartbench Gaming. Plus there is early benchmarks of Quadrant scores of 2100 tablets running the Exynos 4210. There is a reason why Samsung Galaxy S2 is including Tegra 2 in some regions.
Androidevolution.."One negative surprise on the S2 so far has been the level of GPU performance. So far, most of the early benchmark shows that Exynos 4210 isn’t up to par when it comes to the GPU performance. This is strange given that Samsung was leading the market when they introduced the previous generation SoC ...... Smartbench 2011 GPU numbers are once again, very disappointing"
Tegra 2 vs Dual Core-Snapdragon (HTC Pyramid)
This thing got smoked in Smartbench with gaming and productivity.
" Their tests confirm that the Pyramid indeed houses a dual-core chip, but the popular Smarbench 2011 shows a CPU and GPU that simply don’t hold up to the Tegra 2 chip found in the LG Optimus 2X and Motorola Atrix 4G"
Something to remember, Tegra may be the fastest, but........ Just like a computer in your house the slowest component is the driver or the memory storage is usually the one that slows it down or the motherboard. So having the fastest cpu makes your bench look good but in practical use it is not better performance.
If the sole purpose is to game then, yeah ok that may be a winner, but get real, using the phone for gaming is such a waste of technology
Mind you synthetic benchmarks aren't the best way to show performance, quadrant and linpack are both easy to inflate scores just by changing a single value. As for ram, it's hard to compare ram seeing that Ios and Android handles memory differently.

+1. Synthetic benchmarks are not a good indicator of real world performance.
Just having a little look around and found that the HTC One XL has listed 32GB internal storage on the Australian HTC site.
I'd attach a link, but it looks like you just have to google it ;]
Unfortunately because the only thing holding me back from getting the XL was 16GB of storage, Ive already purchased the HOX, just waiting for it to arrive.
Sorry if this is old news.

Krait Dual-Core 1.5Ghz 28nm > Tegra 3 Quad-Core 1.5Ghz 40nm
If you had a Dual Core phone before, the Tegra 3 isn't much different, since it has to scale over to the 4 cores which is less likely, whereas the Krait is similar to the A15 Architecture and produces better performance which is why no-one has experience lag on the HTC One S due to faster processor and the smaller resolution. Also battery life is easily going to be better due to the 28nm compared to Tegra 3 Companion Core 40nm.
The Tegra 3 GPU isn't much powerful to the Adreno 225, on GLBenchmark they are both are equal (720p Offscreen, 1 each) and Adreno 225 beats the Tegra 3 in Nenamark 2.

Well we can't really allow the One X to fight against the One S because there are too many variables. When the AT&T version of the One X comes out with the LTE support and One S' processor, then we can actually see the difference.
I agree that sometimes dual core processors can process fast through benchmarks, but then benchmarks can be flawed and tampered with. Also with many factors which could affect raw power testing, as you said resolution difference, background services, etc.
There is a reason why the One S doesn't have the carousel affect when sliding the bars on the bottom to switch menus. It runs a smaller OS, which in turn allows it to have a smaller footprint than One X's heavily bloated OS.
It may be fast over a short period of time, to process small things, but, let's say for computers, if I had to render a 1 minute video on a dual core machine, it will take 5 minutes, but on a quad core machine it will take 2.8 minutes or below. I think of the long period of using a quad core device, and the capabilities in which it hasn't fully utilized yet.
Also when you said dual core, yeah, I had a Samsung Galaxy S II and a Samsung Galaxy Nexus. You can get their ROMs under 200mb for the full Touchwiz experience, while to get a full Sense 4.0 experience, you have a ROM which can go over 600mb easily. The Galaxy S II in my opinion was a very fast device when I used it, all the raw power it had, but as I said, sometimes you just can't compare them because there are way too many variables. Physically if none had an OS, okay fine, you can test, but the way many people test speeds have affected results in at least two ways.
That's my opinion, many people think differently, but I guess people could see where I'm going
Have to say the one s runs like a champ. That thing fast. Faster than my one x. Smooth and snappier. I don't care to much about quadrant but the ones s I've tried scored 5400 lol and transitions were butter. Snappier and smoother than my quad core lol. On the other hand I've also tried the one x dual core from att. I think.that's the same as the xl. That one was laggy and not smaooth as the one.s so one s wins.

Ummm, what? If you take an Intel E6600 and a Q6600, the quad core is twice as powerful, in theory. You can't get a 5 times speedup! You can't even get a 2 times speedup, since some of the workload isn't parallelisable.
This is completely irrelevant, however, since has already has been mentioned, the Tegra3 and Snapdragons are quite different.

Sorry, that was a pretty bad comparison, since I don't really have a quad core computer, only 8 core (4cores+imaginary4cores) I don't really know the exact comparison, but at least you know where i'm trying to get at
Seems with every smartphone that comes to the USA it gets some sort of Snapdragon Processor by Qualcomm and people do nothing but complain. So how does this Snapdragon S4 processor compare to every other dual-core processor out there and even the Tegra 3? Looked up some benchmarks and both seem to have their advantages and disadvantages. But what I really want to know is which one is better for real world performance, such as battery life, transitional effects, and launching apps. Couple people said Sense 4 is very smooth and "has LITTLE to no lag"? How does this processor display web pages in Chrome?
Read the thread "Those of your who are waiting too compare GSIII to HTC One X" in this forum. It only has about 6 pages but has a ton of information. Short answer is that the Qualcomm chip kicks serious ass.

yes and no, the tegra 3 does have a better gpu so in theory, better games. however, game makers cater to the mass. most androids that are active are mid-range, android 2.2 or 2.3, have a resolution of 480x800, and last years (or older) processors. although most will be made to work on the t3 and s4, it will be compatibility issues, not optimization. nvidia will have a couple games "t3 only" but even those will be made to work on other phones. now that ics is cleaning up some of the splintering of apps, we'll see some better options on both fields.
in short, yes the t3 is a better gaming chip. but for the battery life, games available, and current bugs i would suggest the s4. i may change my mind when the refreshs come out q3-4, we'll see.

Correct. However, most games are not optimized to utilize the Tegra to its fullest potential. That should change by the end of the year. The other point is that the S4 is just as good as the Tegra un terms of gaming performance. IMO, you should decide between these 2 processors by looking at the main area where the S4 truly has the advantage thus far, and that is battery life. So far, the battery life advantage goes to the S4. Just read the battery life threads in this forum and for the international X. It took a few updates to the Transformer Prime to start having pretty good battery life. The One X, will get better in that department with a couple more updates for battery optimization. The S4 starts with great battery life and will get even better in that department.

I say the snapdragon S4 is a better chip right now. The tegra 3 gpu is great and with the tegra zone games it really looks great. But he 4 cores CPU is really for heavy multitasking so you candivise the work between all four cores. They are A9 cores vs the custom qualcomm which is close to A15. It mans that for single threaded task and multi threaded task the snapdragon will whoop tegra 3' ass. Opening an app, scrolling through that app sect... also browser performance is slightly better on the qualcomm chip. Basically tegra 3 can do lots of things at the same time with decent speed vs the S4 chip which can do 1 or few more things at lighting speed.
The S4 is almost 2x faster than any other dual core out there. Anandtech did a few nice articles on the S4, including benchmarks vs tegra 3.
In real use, the S4 should be much better, because not all apps are multithreaded for 4 cores. The S4 completely kicks the Tegra 3's ass in singlethreaded benchmarks. I also expect the S4 to be better at power management, because it is made on 28nm node, instead of 40 nm, so its more compact and efficient.
About 23 I'd say

The difference in DMIP's is where the S4 really whomps on the T3. All the T3 has going for it at the moment is it's GPU. If you don't care about some additional gaming prowess, the S4 is the way to go.

Just to add to that and to be fair, S4 is at around 7000 at antutu benchmark while tegra 3 is at around 10000. I still prefer the S4
Eh...
It wins in 1 benchmark specifically enabled to take advantage of more than 2 cores. So if you want to play tegrazone games and have some basic lag, the T3 is for you. If you want to have a near flawless phone experience, and have decreased graphical performance in some wanna be console games, then the S4 is the way to go.
Actually you wont really notice the lack of graphics performance on the snapdragon s4. Its about 10% slower in most benchmarks but outperforms the tegra3 in a few as well. However i have a sensation xl with the adreno 205 which is only a quarter as fast as the adreno 225 and all games including deadspace, frontline, blood glory runs smoothly on it. To say the snapdragon s4 is inferior because of the slower Adreno 225 is really nit picking to me. For me bigger reason to choose one graphics chip over another is flash performance and this is where the exynos mali 400 kicks the adreno 225 in the balls. It handles 1080p youtube videos in browser without a hiccup while the 225 chokes even on 720p content.
Let me answer this. How good is it? More than good enough. Almost all apps and games are catered to weaker phones so the T3 and S4 are both more than good enough.
And my two cents, the S4 beats tegra 3

Let me start by saying I'm not a pro when it comes to electronics but I do have an understanding on the subject.
The thing to realize about these processors, and most other processors available today, is that the s4 is based on the cortex a15 while the tegra 3 along with the new Samsung are based on the a9. The a15, at the same Hz and die size is 40% faster than the a9.
S4 = dual core Cortex A15 @ 1.5GHz - 28NM
Tegra3 = quad core Cortex A9 @ 1.5GHz - 40NM
Exynos 4(Samsung) = quad core Cortex A9 @ 1.5GHz - 32NM
S4 so far, in theory, is 40% faster per core, but having two less. Individual apps will run faster unless they utilize all four cores on the tegra3. Because the s4 has a smaller die size, it will consume less energy per core.
The actual technology behind these chips that the manufacturers come up with will also affect the performance output, but the general idea is there. Hope that helps to understand a little better how the two chips will differ in performance.

The S4 compared to the Tegra3 says it all. dualcore that beats a quadcore in almost everything.
Intel released the first native dual core processor in 2006 and shortly thereafter released a quad core which was basically two dual cores fused together (this is what current ARM quads are like).
That was 6 years ago and these days pretty much all new desktop computers come with quad cores while laptops mostly stick with dual. Laptops make up the biggest share of PC sales so for your everyday PC usage, you'll be more than comfortable with a dual core.
You really can't assume mobile SoCs will follow the same path, but it's definitely something to consider. I think dual core A15-based SoCs will still rule the day this year and next at the very least.
I was really on the fence about the X or the XL. But the S4 got me. Not having 32GB is already bugging me. But the efficiency (and my grandfathered unlimited data paired with Google Music) is definitely worth the sacrifice. Very happy so far! Streaming Slacker, while connected to my A2DP stereo, running GPS was great. I'm not a huge gamer though. I miss Super Mario Bros being the hottest thing!

This is inaccurate.
The Exynos 4 and the Tegra 3 are based on the ARM A9 reference design.
The Qualcomm Snapdragon S4 is "roughly equivalent" to the A15, but not based on the A15. The same was true for Qualcomm's old S3 (which was equivalent to something between the A8 and A9 design)
One thing that most people don't realize is that Qualcomm is one of the very few companies that designs its own processors based on the ARM instruction set, and while S4's is similar to the A15 in terms of architecture, it's actually arguably better than the ARM reference design (e.g. asynchronous clocking of each core which is a better design than the big.LITTLE or +1 design).
Hello guys,
Well i need some advice from real people. There are two models in my country: international One X and One XL. You know what the differences are. So maybe someone tested both with same kernel and os version. Which processor is better? Tegra 3 or Snapdragon clocked Krait S4?
In your opinion which one to buy and why? Or just go for One S?
P.S. There are like 1 million reviews and benchmarks and like every single one is different.
Thank you for your opinion!

Sent from my One X using xda premium
Speed difference is negligible. S4 wins in a lot of benchmarks, and Tegra wins in a couple. And you would likely not see much difference in real world use. Same performance, but better battery life on the S4.
Also, at launch the Tegra version had graphical glitches, and a number of other bugs that were attributed to the Tegra chipset. Not sure if these were ever sorted out, as I don't keep up with that version. But many were doubting it would be fixed anytime soon, as NVIDIA is notorious for taking forever to address such issues.
And you might think you don't need LTE. But its not just about speed. I get fantastic data reception at my house now under LTE, where under HSPA+ it was dismal (1 bar, with frequent connection drops). At some point, you may find your self in a location(s) that has poor HSPA reception, and LTE will save the day.
Every Tegra device I've put my hands on has always seemed far too slow and glitchy for the supposedly excellent hardware and software behind it. Except the Zune HD, but everyone ignored the Tegra 1 for some reason. S4's got better battery, chances are they are basically identical in real world use. The only downside to the S4 is the lack of official support for the Tegra games, but I'm sure we'll be able to play them in time.
To be honest, we might be able to do them now if Chainfire3d works for us.
I'd buy a Qualcomm based device over a Tegra based one any day of the week for all of the reasons already mentioned.
The S4 may be "only" dual core, but it's the better chip.
