ARM Bifrost Architecture

So G71 MP8 has about 2/3rds the performance of Adreno 530 in Snapdragon 820 and the same performance as Tegra K1.

 

There is an update coming to the Mate 9 to fix some GPU driver issues. Hopefully it will improve the GPU performance to match the results on the Kirin 960 presentation where it outperformed the Adreno 530.

 

Yeah those figures are on the much lower side with regards what to expect from G71.

Now it is much better.

 

Does it have some impact in any important load ?

 

I have compared fps of games running on a Mali/Adreno GPU (Note3/Note4) and Mali's would get better results compared to the superior raw performance of their counterparts ( the Note 3 Mali GPU was like half the raw power but just run games at about the same fps' as the Adreno 330 ). I don't know about current versions because I don't have them to compare and almost nobody seems to do this kind of tests ( just some chinese youtube accounts that are hard to find and difficult to understand for me xD ).

 

I would not take it very seriously when it puts lower end Mali GPUs configurations over the Mali T880-MP12 inside the Exynos 8890. And there is a lot of variations between devices with the same SOC ( maybe som fake results are mixed in or tweaked kernels in action ). This tables are made with the uploaded results from users... not very trustworthy.

 

I was not questioning their tests, just the results that were shown. Yeah, there are results from reliable sources too, but the majority are from the garden users. When you see a low end GPU over a high end one, or the same soc getting twice the performance in different devices... you can see something is wrong.

And as synthetic benchmarks they are, they don't always represent real world gaming performance as I declared before: https://www.gamebench.net/blog/samsung-galaxy-note-4-beats-every-other-phone-asphalt-8

 

Mali G71 MP20 and LPDDR4X for 30 to 34GB/s bandwidth (assuming 2*32bit) in 10nm Exynos 8895:

If we look at how well the G71 MP8 in the Kirin 960 fares right now, we might be looking at something that matches the apple A9X in GPU performance.
Depending on the clocks, it might even bite at the heels of an Iris Pro 580.

 

The samsung web page says 60% more graphics performance from 8890 so I guess it is clocked aroud ~450MHz.

 

Hum..then it's not going very high.
Maybe they're targeting thermally sustainable performance this time, for GearVR.

 

Yep, that is their target this year. Same as Qualcomm.

 

I like the pace at which ARM is interating on its GPU, G71 was the first steps of their new architecture, the G72 should be interesting to follow.
Contrary to Intel which seems to have eased its effort on the GPU front, ARM is improving its product and closing the gap with its competitors with every iterations of their products.
