AWS has the Graviton ARM CPU that is pretty competitive but you can only rent them.

#23Could be the best thing that's ever happened for RISC-V!
Maybe fine for Android but this will set their windows plans back another decade if it happens
It has taken them that long to make arm be a thing on windows and that’s building on people porting stuff to arm for Mac to finally get momentum.
RISC-V with windows will be an eternity to be feasible.

Ampere has Graviton-like chips that you can actually buy, but neither Graviton or Ampere are really in the same market segment as Qualcomm and Apple.

Most people do not realize how slow RISC-V is right now. Yes, it will definitely get better, but it will take some time given how far behind it is. Like 30x slower than a top of the line Apple Mx series CPU. Maybe there is a high performing RISC-V chip out there but I haven't yet run into one. RISC-V benchmarks: https://browser.geekbench.com/search?q=RISC-V . Compare to an Apple M4 benchmark: https://browser.geekbenc…
Is it slower by design or just because it’s implementations have not been aggressively optimized?

#28Earlier quoted context omitted.
Qualcomm have a Plan B. This time last year they were all over the RISC-V mailing lists, trying to convince everyone to drop the "C" extension from RVA23 because (basically confirmed by their employees) it was not easy to retrofit mildly variable length RISC-V instructions (2 bytes and 4 bytes) to the Aarch64 core they acquired from Nuvia. At the same time, Qualcomm proposed a new RISC-V extension that was pretty muc…
Dropping "C" overnight and thus making all existing Linux software incompatible is completely out of the question. Android was never really Linux though.
This is officially too much quibbling, even if we settled philosophical questions like "Is Android Linux?" Then "If not, would dropping C make RISC nonviable", there isn't actually an Android version that'll do RISC anywhere near on the horizon. Support _reversed_ for it, got pulled 5 months ago

I believe Graviton is competitive in the server market yes, but not in mobile or laptops.

#30Let’s just assume this happens for a moment. What do Android OEMs do? They can’t use Apple chips, or now Qualcomm chips. Switching to another architecture is a big deal. Would this basically hand the Android market to Samsung and their Exynos chips? Or does another short term viable competitor exist?
There are probably Risc-V companies eagerly anticipating an opportunity in that space, but I don't know if any are in the performance ballpark right now.
