I am pretty sure https://en.wikipedia.org/wiki/Fujitsu_A64FX beats the stuff out of M1 and has the numbers to prove it. The question if there will be a good deal for Fujitsu to even consider consumer segment. And of course how much work would it take to scale it down from 48 cores to 8 cores and keep the power efficiency (Fugaku has the first place in Green500 list).

A64FX will only beat M1 when using SVE. For desktop workloads it's probably no contest. But at least it has 32GB RAM!

The OP was criticizing all vendors for dropping the ball on "gigantic memory bandwidth, 8-way decode, re-order buffers twice as deep, specialized instructions for x86 translation and reference counting". A64FX has all that (incl. assistant cores in addition to the regular ones and on-chip RAM with HBM interface) AND SVE, not just bare SVE as your comment seems to imply. And of course a big redesign would be necessary, I never implied it's ready to be put in the next MS Surface. But screaming that all processor vendors are 100 years behind Apple is a bit questionable.

So my thoughts were: cool, Apple is bringing some of the processor developments to mass market that I didn't think would hit the market for another 5 years. I am just a bit sad to see everyone (esp on HN) saying it was never seen before.

The Fujitsu chip is amazing too! But I am only familiar with common desktop and laptop CPUs, not HPC specialty hardware.

Sounds like part of the special sauce in the M1 is bringing supercomputer architecture to laptops. That seems like an amazing feat too.

Also, I don't think I was "screaming" about "100 years". Maybe you are thinking of someone else's comment?
