Cloudfare to switch to 100% ARM, says would be worth it even if Intel were free

Very interesting stuff. A lot of people used to the dominance of Intel had a lot of arrogance on this topic, saying ARM couldn't scale to such uses, but there was never anything in the ISA itself limiting such expansion, it's clean and sane and scalable.

Cloudfare says they're so much more efficient that it would be worth it even if Intel gave their processors for free, for their server use. Fascinating stuff.

Given what CloudFlare does, it would probably also be better off switching to an all Atom server configuration since low-grade web serving isn't really what high-end Xeons are designed to do.

Definitely interesting, but yeah, the workload and nature of their code has quite a bit to do with it. Still cool.

ARM has been filling specific server/datacenter roles that Intel and AMD aren't interested in pursuing for for decade(s).

At one end of the spectrum you have Xeon Phi at 288-cores per server and 1.2KW of ridiculously powerful x86 compute performance, RISC servers using high-end ARM designs/OpenPOWER, and of course GPGPU compute clusters using Teslas

At the other end of the spectrum you have Atoms with 16 cores using under 10W, or ARM equivalents if the application is better suited to RISC.

The Xeons and EPYCs really only cover a slice in the middle of the market. It's a pretty big slice but there will always be fringes that Intel and AMD's portfolio of products don't suit particularly well.
