mem bw between cores matters for .... literally all workloads that are not single-core (read: all). And FP8 matters not at all cause inference on cpu is too slow to be of any use whatsoever in the day…

Yes it does. LPCAMM path is still dozens of millimeters. Soldered on is one mm or less.

ANDI is not 1-extended (though that would be nice) it is 0-extended. MIPS only has 2 extension modes for immediates - sign extended and zero-extended. all logical ops are 0-extended, all arith ops are…

IF you care to read the article, they indeed do not blame the architecture but the available silicon implementations.

Entirely disagreed. In a simple step by step emulator it can be as much as 30% of the time spent. In a jit indeed it is less of an effect.

MIPS (the arch of which RISCV is mostly a copy) is even easier to emulate, unlike RV it does not scatter immediate bits al over the instruction word, making it easier for an emulator to get immediates…

Oh, FFS, who asked for this? Why not fix perf issues, or autofill randomly breaking requiring a restart?

aarch64 is not an extension. It is a whole new architecture having NOTHING in common with ARMv7 and below. Nothing!

Graviton, Apple M-series... That variable-length encoding and strongly ordered memory model will do x86 in sooner and not later.

And that may be true, but the point remains: it is illegal to make cheap cars due to regulations requiring a lot of features that cost a lot of money to implement.

I disagree. This feature protects people who do not know better. Those who do, instead of raising their blood pressure by writing rants, can simply disable this feature.
