Indeed, it is a little faster single core and a little slower in multi-core on average compared to my 24-core Zen 3 EPYC (https://browser.geekbench.com/v5/cpu/compare/13330272?baseline=10516638 https://browser.geekbench.com/v5/cpu/compare/13330272?baseli... - which I expect to be slightly slower than the new 24-core Threadripper Pro 5965WX) - certainly comparable in terms of performance. But no word yet on if the M1 Ultra supports ECC RAM or how many PCIe lanes.
