Apple Another Apple-to-switch-Macs-to-ARM post. "Apple engineers have grown confident that the chip designs used for its mobile devices will one day be powerful enough to run its desktops and laptops, said three people with knowledge of the work, who asked to remain anonymous because the plans are confidential. Apple began using Intel chips for Macs in 2005." No idea when Apple will make the switch, but they will do it. I'm thinking 5-10 year timeframe.

I don't understand: even if Apple could get that much of a performance boost by using GPGPU on ARM, couldn't they also get the very same perf boost with GPGPU on x86?

simple answer: if they want to switch to ARM than they could use GPU to compensate speed difference between ARM and intel x86 chips!


and even on desktop x86 you will need to utilize GPU in future if you want real impressive speed gain!
at the end speed of x86 would be less and less relevant! - "it should be only fast enough for "Office-like" jobs..." and real speed (where it is needed) will come from GPU.

even AMD bet entire company on this premise! - CPU part could be anything (ARM/x86); it does not matter. GPU is one that count. look at latest AMD GPUs - they go so far that you can pass pointers from x86 directly to GPU, they add exception support, virtual memory and page tables, calls and conditional branches, integer operations with 256 GPR. it looks like complete CPU and still massive SIMD monster.

they only need "fast enough" x86 execution since real speed will come from SIMD GPU.
