GPU Performance
3DMark
Although it's our first GPU test, 3DMark doesn't do much to show Adreno 420 in a good light. 3DMark isn't the most GPU intensive test we have, but here we see marginal increases over Snapdragon 800/Adreno 330. I would be interested in seeing if there are any improvements on the power consumption front since performance doesn't really change.
Basemark X 1.1
Basemark X 1.1 starts to show a difference between Adreno 420 and 330. At medium quality settings we see a 25% increase in performance over the Snapdragon 801 based Adreno 330 devices. Move to higher quality settings and the performance advantage increases to over 50%. Here even NVIDIA's Shield with Tegra 4 cooled by a fan can't outperform the Adreno 420 GPU.
GFXBench 3.0
Manhattan continues to be a very stressful test but the onscreen results are pretty interesting. Adreno 420 can drive a 2560 x 1440 display at the same frame rate that Adreno 330 could drive a 1080p display.
In an apples to apples comparison at the same resolution, Adreno 430 is over 50% faster than Adreno 330. It's also faster than the PowerVR G6430 in the iPad Air.
Once again we see an example where Adreno 420 is able to drive the MDP/T's panel at 2560 x 1440 at the same performance as Adreno 330 can deliver at 1080p
At 1080p, the Adreno 420/S805 advantage grows to 45%.
I've included all of the low level GFXBench tests below if you're interested in digging any deeper. It's interesting that we don't see a big increase in the ALU test but far larger increases in the alpha blending and fill rate tests.

Yes, but can it run Crysis?Krysto - Sunday, May 25, 2014 - link
No. But Tegra K1 probably can, not just because it's twice as fast, but because it has a much more PC-parity API than Adreno 420.errorr - Friday, May 23, 2014 - link
I wonder what the heuristics are like for switching graphics from TLDR to direct rendering are and whether they are tweaked depending on tablet or phone usage.Abandoning TLDR to use that giant amount of bandwidth is going to use oodles of power. This is why I doubt you will see NV Kepler on a phone and restrict it to tablets.

True. Remember NV do have Maxwell shipping on desktop form so its mobile variant is probably in testing/optimization phase right now with possibly reserving it for near future opposition.Krysto - Sunday, May 25, 2014 - link
Denver + Maxwell at FinFET 16nm, now THAT'S a beauty to behold. Hopefully Nvidia doesn't have anymore delays, though.Krysto - Sunday, May 25, 2014 - link
No VP9 decoding? And when is Qualcomm going to open source its baseband firmware? Otherwise we can just assume it's backdoored these days, therefore making the whole phone vulnerable to attacks and espionage.Keermalec - Saturday, August 2, 2014 - link
OK so your excuse, Anand, for not including Tegra K1 or Exynos 5433 in your benchmarks was that you didn't have them available on May 21. Now you do as K1 and Exynos 5433 are shipping while Snapdragon 805 still is not.So can you correct this article to show 805's performance vs the real competition? Pitting it against last year's Tegra 4 and Exynos 5 Octa is just wrong.

Wow, didn't expect that my Tegra K1 is so much better than these SoCs. 50% more graphics performance and even 10% to 20% more CPU Performance (the week part of the Tegra K1).Edwardnew - Tuesday, April 14, 2020 - link
