Searching on Geekbench for Apple M1 ultra single core scores returns values mostly in the 1770-1780 range. E.g. https://browser.geekbench.com/v5/cpu/14597244
Most 12900K score are between 1900 and 2200 but then there is this outlier with single core score of 1252: https://browser.geekbench.com/v5/cpu/14572307
Intel certainly wins on single core, but the m1 Ultra multicore scores are still impressive in comparison being generally 23-24000, while the 12900k are around 15-20000.
Disingenuous would be to focus on the outlier.
Apple on the otherhand doesn't overclock, focuses on multi-core performance, has great memory bandwidth, and all the submitted scores are within 1%.
The M1 ultra is also 1.32x faster in the multiprocessing benchmark. Looks pretty impressive to me, even ignoring the much less power the M1 ultra uses.
