Is ARM/RISC the future of computing beyond X86?

[Steevo]

No.

We have had threads which point out the performance of ARM devices and in certain well tuned applications they excel.

POWER9 & ARM Performance Against Intel Xeon Cascadelake + AMD EPYC Rome Review - Phoronix

www.phoronix.com

The linked site compares Arm and PowerPC architecture to AMD and Intel X86-64 in numerous benchmarks.

Thoughts or evidence to the contrary?

Only Apple believes this to be true.

To be fair, they're comparing really expensive hardware to very inexpensive hardware. Epyc 7742 is 64c/128t and they're using two of them at $7800 (and 225w) each. Cavium ThunderX has 48 cores for like $2400 and a paltry 400w total system power. It's not really an apples to apples comparison.

Since when and in what universe is POWER9 cheap?

Didn't say it was. The argument was x86 vs ARM so that's what I focused on. To be honest, Intel Atom versus ARM makes more sense than Epyc/Xeon.

They're comparing something worth like $2500 (Cavium) to something worth well over $20,000 (Epyc).

ARM simply does not have good enough designs outside mobile for HPC and similarly x86 is nearly non existent in mobile. The moment ARM will try to change that the two will simply converge, it's not like ARM can find some sort of optimum that AMD and Intel have failed to dig up.
