Given that today's HPC architectures are mostly power constrained, and a majority of the FLOPS often come from GPUs (for their flop/watt ratios), this direction is not surprising.

ARM has been making major strides in the high performance area. The new AWS Graviton processors are pretty nice from what I have heard. And then there's the ARM in Mac. Yup and Julia will run on all of these!

While I say all of this, I should also point out that the top500 benchmark pretty much is not representative of most real-life workloads, and is largely based on your ability to solve the largest dense linear solve you possibly can - something almost no real application does.

(The website is down, so I haven't been able to look at the specs of the actual machine).

I can't help but think that the top minds from Cyrix aren't feeling both smug at the vindication and dismayed that they were just a little too ahead of the curve.

The writing was on the wall that RISC would win, but the x86 juggernaut appeared unbeatable.

Get ready for a surprise then: all those FLOPS are coming from the ARM cores.... This beast has no GPUs:

Worth noting that Fugaku has no GPU/accelerator; all the compute is located in-core (cpu). The core itself has some GPU-like qualities, of course, since it's more optimized for semi-uniform compute throughput than a "normal" CPU is.
