MediaTek runs Mali's latest video drivers which are the r4p0 drivers which I haven't been able to get in order to test yet. The Chromium guys should be pushing it to the dev channel update within a few weeks so I'll be able to test it then. Doesn't matter too terribly much since it's still a GLES3 feature set and we use a lot of other features to speed up emulation. So /if/ they fixed their slow buffer streaming then performance will increase a bit due to less CPU overhead in the GPU drivers.
The CPU should be quicker, but of course there aren't any fruitless AArch64 CPUs out so we don't know how it'll perform. It would still need to run the ARMv7 CPU core since again, I don't have the CPU to complete the AArch64 emitter or the JIT. I've got a AArch64 emitter started, but it'll take many months after I get a device with it to get both the emitter and a JIT to point the ARMv7 JIT is.
