Qualcomm tends to stagger the introduction of new CPU and GPU IP. Snapdragon 805 ultimately serves as Qualcomm's introduction vehicle for its Adreno 420 GPU. The performance gains there over Adreno 330/Snapdragon 801 can be substantial, particularly at high resolutions and/or higher quality settings. Excluding 3DMark, we saw a 20 - 50% increase in GPU performance compared to Snapdragon 801. Adreno 420 is a must have if you want to drive a higher resolution display at the same performance as an Adreno 330/1080p display combination. With OEMs contemplating moving to higher-than-1080p resolution screens in the near term, leveraging Snapdragon 805 may make sense there.

The gains on the CPU side are far more subtle. At best we noted a 6% increase in performance compared to a 2.5GHz Snapdragon 801, but depending on thermal/chassis limitations of shipping devices you may see even less of a difference.

CPU performance barely improves compared to the 2.5GHz S801 variant but it can deliver similar GPU performance at 2560x1440 to Adreno 330 @ 1080p. Looks like a good fit for Quad HD Android 4.4/4.5 devices launching H2/2014.

well now it's confirmed, 2014 fastest android SoC is Tegra K1 (better CPU and GPU performance).
and next year the lead will be even higher with Erista / Maxwell...
interesting to see how it will translate in tablets design wins (both S805 and K1 don't have integrated modem so their primary market is tablets)

looks excellent and we know that quallcomm parts do well in power consumption.
Another point to note, this matches mullins in 3dmark ice storm[haven't checked others] seriously impressed but arm...

It looks like Mullins has about a %25 lead to me, unless I'm looking at the wrong scores. . .

As far as GPU is concerned, I dont think it does. Fastest Mullins SKU probably has a CPU advantage, which would partially explain the higher (overall) 3DMark scores, though that S805 score seems abnormally low (pretty much same as S801, despite up to 50% faster GPU scores in other tests) - there might be something wrong here. Also, I'd say A10 6700T draws more power than the S805, but thats just my guess.

I'm guessing this is what the LG-G3 will be using. We'll find out in a few days. Nice scores.

the 3DMark Icestorm overall scores are 25% higher. GPU score is almost 40% higher.

Anandtech overall - 24867

techreport overall - 24775

hothardware overall - 24918 graphics - 27844

http://hothardware.com/Reviews/AMD-...nstream-and-LowPower-2014-APUs-Tested/?page=9

Thats a hammering on the GPU side. AMD's GCN is a far superior architecture compared to anything Qualcomm has.

the CPU performance advantage is even more lopsided. Puma is faster than Baytrail which is faster than Krait.

Sunspider 1.0 (lower is better)

Mullins - 435
S805 - 670

Kraken (lower is better)

Mullins - 4614.2
S805 - 6764.1

Mullins is in a class of its own in raw performance.. The only aspect we need to wait and see is power consumption on Mullins. Mullins might draw more power than S805 , but with a 4.5w TDP and 2.8W SDP I am sure Mullins will be competitive in perf/watt.

Seems like Tegra K1 is going to win this round regarding performance.

Well.. In phones? Who knows? I'd say it is very very probable that Nvidia can underclock the TK1 to make it fit into a phone and yet have better performance than the S805.

Nvidia claims that Jetson uses 11W because of additional hardware, non low power RAM, and well.. it's running linux , using different governors etc.

With the right hardware and system software optimizations, I wouldn't be surprised if Nvidia can get TK1 to fit into a phone at stock clocks or with a very little underclocking.

TK1 has to beat Mullins convincingly to get that credit. Let see actual products running TK1 and Mullins. Computex will reveal if AMD has any interesting design wins for Mullins.

the big question to be answered is what is TK1 actual power consumption in a shipping product. Nvidia has overpromised and underdelivered for generations on Tegra. so lets wait and see.

I was thinking Mullins is exclusively a Win 8.1 SoC. So it's not competition to TK1. Mullins competitor is Intel and their "free SoC" (contra-revenue) program. Good luck to AMD to fight against that...

PS: 200M tablets should be sold this year but less than 15M will run Windows

The Snapdragon 805 GPU beats the Mullins GPU by ~ 10% in GFXBench T-Rex HD Offscreen.

As Anand said, clearly S805 doesn't have optimal drivers for 3dmark ice storm unlimited, because the scores are essentially the same or even slightly lower than S801, which is nonsensical!

The Xiaomi Mi Pad is an actual product, and it already has > 60% higher performance in GFXBench T-Rex HD Offscreen in a small 7.9" chassis compared to Mullins in a 11.6" chassis on AC power.

So for non-graphics purposes its performance is practically similar to Snapdragon 800 which we've had since the likes of Galaxy S4+? Can't really say I'm impressed with the upcoming generation in that case.. but then again I don't play games on my phone.

Snapdragon 805 is on the same 28nm HPM fab. process node as S800 and S801, so the Krait CPU performance gains are reaching a point of diminishing returns. It is interesting to note that Cortex A15 has significantly higher CPU performance headroom than Krait 450. This could explain in part why Qualcomm is moving to the even higher performance Cortex A57 next year for their high end 20nm SoC. Obviously 64-bit ARMv8 architecture is another key feature of A57 too.

you are just talking about info on marketing slides. lets see independent third party reviews. Why T-Rex ? because Nvidia shows a disproportionate lead. On the contrary the performance across a wide range of benchmarks need to be seen

Here is a review or preview whichever way you consider it

3DMark Unlimited - 25737

http://www.evolife.cn/html/2014/77075.html

thats 5% faster than Mullins.

If I wanted to show you a test which is much slower on TK1 i could pick WebXPRT (433 for TK1 vs 749 for Mullins). Thats not the point.

We need to look at results from independent third party reviews across a wide range of benchmarks before judging a product. perf and power need to be measured.

No, TK1 GPU is ahead in numerous GPU benchmarks, including GFXBench Manhattan, GFXBench T-Rex, and 3dmark ice storm unlimited. Note that GFXBench is arguably one of the best pure graphics benchmarks in the ultra mobile space (although obviously no substitute for real world gaming benchmarks which basically don't exist yet on ultra mobile platforms). 3dmark ice storm unlimited is fine as a benchmark too, but the GPU performance differences do not always scale well from one GPU gen. to another.

3DMark Unlimited - 25737

The Chinese article you linked to is not describing any real world ultra mobile product as far as I can tell. The CPU operating frequency is too high to maximize CPU perf. per watt.

A real world production-ready Mi Pad 7.9" tablet was measured by Xiaomi to have ~ 30,000 combined 3dmark Ice Storm Unlimited score, which is significantly higher than Mullins.

Let me remind you again that the TK1 GPU has 192 CUDA cores operating at a very high frequency (relatively speaking).

We need to look at results from independent third party reviews across a wide range of benchmarks before judging a product. perf and power need to be measured.

The perf. of Mi Pad is already largely a known entity. And to fit in a 7.9" tablet chassis, the power efficiency of the SoC and system components needs to be exceptional too. We will find out next month, but the writing is on the wall so-to-speak.

What about Cherry Trail? I suspect 14nm Cherry Trail will easily beat those 28nm SoCs.

3dMark ice storm is a very good benchmark. you can see the Tegra K1 around 65+ % faster compared to Tegra 4 according to the chinese site. if you take xaomi results its a doubling wrt Tegra 4.

its a TK1 review. So since you are seeing different results from diff sources lets wait for actual product reviews from sites like anandtech

The problem is too many times in the past Tegra has proven to be poor in perf/watt. Overheating also is a concern. 4 A15 cores at 2.2 Ghz is no joke even for a tablet. do not expect the TK1 GPU to run at 1 Ghz. the best case would be 700 - 750 Mhz if it has to stay within a 5W TDP suitable for fanless tablets.

Ultra mobile products are preconfigured platforms. Benchmark results are virtually the same across all review units because the hardware and software is the same across all review units. There is no difference between Xiaomi clicking a button to run a graphics benchmark than any third party reviewer clicking a button to run a graphics benchmark.

3dMark ice storm is a very good benchmark. you can see the Tegra K1 around 65+ % faster compared to Tegra 4 according to the chinese site. if you take xaomi results its a doubling wrt Tegra 4.

Tegra K1 in Mi Pad performs quite well in 3dmark ice storm unlimited, but the difference in GPU perf. is likely less than 2x compared to Tegra 4, which is on the low side and indicates some bottleneck in the benchmark (the perf. differences in games should be in the 3-5x range on average).

Anyway, the fact that Adreno 420 performs no better than Adreno 330 in ice storm unlimited is a bit of a red flag because the fillrate performance of the former is much better than the latter. And if you look at the actual frame rates achieved, GFXBench is a much more graphically-intensive benchmark than ice storm unlimited.

The problem is too many times in the past Tegra has proven to be poor in perf/watt. Overheating also is a concern.

Tegra Note 7 tablet and Xiaomi Mi3 phone never suffered from overheating, nor did they suffer from poor battery life with day to day use. Anyway, the past is the past. TK1 is fabbed on the most advanced 28nm HPM fab. process at TSMC, and the new CPU revision and new GPU have superior perf. per watt compared to prior generation hardware.

It's not just the Xiaomi tablet, there are leaked results for NVIDIA's TK1-based Mocha tablet.

Well we just saw a much faster Adreno 420 performing the same as Adreno 330 in 3DMark, so I wouldn't call it ''the definitive benchmark'' for unreleased mobile products.

3dmark ice storm unlimited is not very stressful for the GPU's in modern-day high end ultra mobile SoC's. For instance, Snapdragon 801 in the new HTC One can achieve > 100fps in Game Test 1, and close to 80 fps in Game Test 2.
