AMD outsells Intel in the datacenter space

Surprising it took so long given how dominant the EPYC CPUs were for years.

Complicated. Performance per watt was better for Intel, which matters way more when you're running a large fleet. Doesn't matter so much for workstations or gamers, where all that matters is performance. Also, certification, enterprise management story, etc was not there.

Maybe recent EPYC had caught up? I haven't been following too closely since it hasn't mattered to me. But both companies were suggesting an AMD pass by.

Not surprising at all though, anyone who's been following roadmaps knew it was only a matter of time. AMD is /hungry/.

> Performance per watt was better for Intel

No, not its not even close. AMD is miles ahead.

This is a Phoronix review for Turin (current generation): https://www.phoronix.com/review/amd-epyc-9965-9755-benchmark...

You can similarly search for phoronix reviews for the Genoa, Bergamo, and Milan generations (the last two generations).

You're thinking strictly about core performance per watt. Intel has been offering a number of accelerators and other features that make perf/watt look at lot better when you can take advantage of them.

AMD is still going to win a lot of the time, but Intel is better than it seems.

Are generic web server workloads going to use these features? I would assume the bulk of e.g. EC2 spent its time doing boring non-accelerated “stuff”.

Intel does a lot of work developing sdks to take advantage of its extra CPU features and works with open source community to integrate them so they are actually used.

Their acceleration primitives work with many TLS implementations/nginx/SSH amongst many others.

Possibly AMD is doing similar but I'm not aware.
