GPU Performance


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

GFXBench 3.0 Manhattan (Onscreen)

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.

GFXBench 3.0 Manhattan (Offscreen)

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.

GFXBench 3.0 T-Rex HD (Onscreen)

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

GFXBench 3.0 T-Rex HD (Offscreen)

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.

    Too bad it seems like the LG G3 might not have this beast... So close LG, so close!

    I wonder what the scrolling performance will be like on the G3 given its resolution and "just" having an 801 chip. I feel like scrolling performance is finally good with the 1080p and the latest generation of processors, but are we going backwards in performance with the leap to 4k?

    Still dunno why they're pushing for even higher DPI on phones, seems almost absurd at this point.

    Because people are very, very simple in the head and think bigger numbers are better.

    High DPI phones will hopefully die a silent and quick death. Even 1080p is overkill for me on any screen smaller than 5 inch, and staying at 720p at that size is great for battery life...

    I don't know man. The difference in pushing and power consumption and price between 720p and 1080p is not that much to deter from the noticeably better quality.

    Say what you will but I (with my less than perfect vision) can still see pixelation at battery indicators or other small elements. Not to mention native full HD content should you wish it. and obviously SOCs today able to cope with 1080p.

    I'm not sure why some people spend as much effort deriding the push for higher pixel densities as they do. Most of it sounds more like sneering for the sake of sneering than having an actual point to make, to me (I'm not saying I know that to be the case here). One should at least make the effort to differentiate himself from the person telling us we should not try to improve the quality of what we see by reaching for more than 60 DPI not all that long ago, because that was "good enough".

    Human vision isn't the simple mechanism some people think it is. Research has shown a density of over 600 DPI can be useful. I tend to agree that there are other ways to make smart phones better at this point, and it's hard for me to imagine that I would be able to see any benefit beyond 300 DPI personally, but I'm not against increasing the ability of our technology to do more than we can use. Perhaps the technology will lead to improvements in other areas, like responsiveness, or fluidity. Seems to me that giving designing engineers all the power they could possibly use can't be a bad thing. :)

    Increased power draw, cost, performance issues.

    Hey looks reasons!
