Performance isn’t there. Why spend 3k+ on this?

M1 Ultra on macOS: ca. 1800 (1C) ca. 24000 (20C) https://browser.geekbench.com/v5/cpu/20798209

Ampere Altra on Windows: ca. 800 (1C) ca. 12800 (80C) https://browser.geekbench.com/v5/cpu/20639458

Ampere Altra on Linux: ca. 900 (1C) ca. 44000 (80C) https://www.tomshardware.com/news/ampere-altra-max-80-ccore-...

Apparently the key to getting performance out of the Ampere Altra is … to just not use Windows? And have a very parallel workload. Yes, a single Altra core is half as fast as a single M1 Ultra core. But it really depends on your use case and other factors (e.g. power efficiency) which one is preferable.

What's wrong with the performance?

A comparable m1 is twice as fast in the above benchmarks?

And that’s Apple’s chip from 2 years ago!

Core for core this is a dog.
