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.

Well, i don't belive it because of benchmarking results. Nvidia promised 60fps in T-Rex HD, and here it is. And Nvidia also promised 2.5x performance on Manhattan Offscreen test compared Apple's A7. And here it is(30fps vs 13.3fps). Well, almost 2.5x.AnandTechUser99 - Thursday, May 22, 2014 - link
NVIDIA had shown us the benchmarks in January.When the iPad Mini Retina (and other A7 devices) had been benchmarked towards the end of January in Manhattan Offscreen 1080p, they had average scores closer to 667 (10.8 Fps). Based off of this score, the Tegra K1 was offering a score ~2.65x that of the A7.
Sometime around March 10th, the average score for Apple's A7 had changed to 803 (13.0 Fps). I assume there was some sort of software update that boosted their Manhattan score.

i'm glad that if it is down clocked to 600mhz in the MiPad, benchmarks shows it's still kicking QC buttGhost420 - Friday, May 23, 2014 - link
on a side note, this is very good for SOC competition...hopefullyArthurG - Thursday, May 22, 2014 - link
So read this:http://en.miui.com/thread-22041-1-1.html
5hours heavy 3D game on 6700mAH battery means that TK1 runs with ~3W
and 11 hours on video
so excellent numbers when taking into account the leading performance

about 5 hours. Hm, I wish they had ran the tests longer... Ideally (for testing purposes, not time purposes) they would have ran everything for 20-25%(+) of the tablets battery life, and used that.OR
Did the tests from 75% or 50% battery.
Using 15 minutes (read: 5%) is a bit low amount of battery wear... It should be pretty accurate, but, I would skew that test a little lower (my experience is phones (over 5 phones) and tablets (over 2 tablets) tend to lose the first few percent of battery the slowest, and, it gives an inflated battery life.
According to the first 5% of battery (from 100% to 95%) on an iPad mini, well, It gave me something like 8 hours of usage playing hearthstone...
Same with video watching on Nook HD+
Same with Video (and reading webpages) watching on 920/1020
Same on reading webpages/playing weak applications on my Moto G
Same with web pages on some cheapass Android LG
Same with video/web pages on my old iPhone 4.
I would guess the real battery is closer to 4-4.5 hours (happy to be proven wrong ^__^) and the SoC is not running max clock (for good reason, no need to run max clock when you already hit a game fps gap, or, the refresh rate of the tablet)

Doesn't Asus have a TF701T? which uses a Tegra 4 @ 1.9Mhz, WITHOUT A FAN? One bad review, because Toshiba don't know how to make a tablet, and everyone thinks T4 runs hot. The fan in the Shield is very quite and doesn't 'spool' up as if T4 was overheating, it runs very smoothly and the the interface is very smooth. Also, streaming AWAY from your house on good WiFi for PC games is working quite well now.And at least NV is updating its software....consistently...unlike most OEMs.

Agreed. Also Denver is in house where 810 isn't. I would expect CPU stuff to show Denver is better on power when taxed as Qcom in house won't be around until late 2015 or Q1 2016 since 810 is 1h2015. The GPU will heavily favor NV (even AMD at some point if they get in with a good SOC) as nobody else but AMD has 20yrs of gaming experience. We already have seen K1 is pretty good against the 805. Odd they ran from battery here..."Here even NVIDIA's Shield with Tegra 4 cooled by a fan can't outperform the Adreno 420 GPU"
Anandtech needs to stop makings dumb NV statements. It's a YEAR old device and won't even be in this race, not to mention it's not getting a ton from the fan anyway which is really there for longevity and temps in the hands for hours (we game hard and for hours so keeps it cool). The fan isn't in there to hit 2.5ghz or something, it's 1.9. This device will be facing K1. Stop taking AMD checks to be their portal site, and you can get back to making unbiased reporting without the little BS NV digs.

So true for the last paragraph !Let's see if Anand will say "TK1 Kepler GPU smokes Adreno 420, providing twice the performance on GFX3.0 bench with half memory bandwidth"
I'm waiting for it, right Anand ?
ams23 - Thursday, May 22, 2014 - link
Technically the difference in memory bandwidth is closer to 50% due to differences in mem. operating speeds for these two SoC's.
