so what's Mali like?

[Nintonito]

On the current driver revision is Mali anywhere near reasonable? At least better than Qualcomm? Also, when the hell are we gonna see PowerVR 600 in a SoC?

I've no idea, as a general rule devs at XDA actually prefer the Qualcomm stuff for documentation and driver support, which may not bode that well for the current Mali GPUs. Hopefully someone with definite knowledge can chime in, as I would love this not to be the case as I eye a Note 4.

Well its already been established by the dolphin devs several tines that Qualcomm is bottom of the barrel. They are awful with their broken and slow drivers. XDA likes them because they are just building Roms, nobody is testing whether the drivers are any good.

Mali latest r4p0 driver contains glBufferSubData bug which stalls driver, this is the main performance bug on both Adreno and Mali. Arm does test drivers internally, no such thing like dev drivers, consumer drivers are pushed infrequently. So I belive they both on pair with Adreno crap. Mali had less bugs overall, but the most important, affecting dolphin performance is still there

Wonderful. Well at least Mali is usually in faster chips anyways. Qualcomm is all CPU throttle and poor cycle efficiency. I would hopefully expect a true Cortex A15 (or A57) to provide a CPU improvement that could offset the persistent driver slowdowns.

It would be still quite interesting to see snapdragon 810 in action since it's a cortex A57 instead of crap krait core. Adreno 430 probably will have v94 driver and I believe that's the same developer driver from the August 7th, just with a different name as it's supposed to be a consumer release
