The Cinebench R23 results for 1950x[1] and M1Max[2], including single and multi-core:
single multi
M1Max: 1562 14970
1950X: 1035 18780
Remember that the M1 Max has 8 high performance and 2 efficiency cores vs. the 16 cores of the 1950x. Again, this is a pretty convincing victory - 1.5x single core perf in a laptop - this is not a HEDT part.[1] https://www.cpu-monkey.com/en/cpu-amd_ryzen_threadripper_195...
2. Multicore Cinebench R23 for M1 Max: 14970; Ryzen 1950X: 18780
Geekbench tests in short bursts, not taxing the CPU thermals. Cinebench is the opposite. In short, CPUs do well on some benchmarks and not so well on others.
