What gave me pause was when my base-spec M1 Air handily beat my admittedly old server (Xeon E5-2650v2) on a single-core compute-bound task [0] (generating a ton of UUIDs). I know Ivy Bridge is 12 years old at this point, but I didn’t expect it to be 2x slower.

EDIT: Also, I know the code in the link is awful; the point is doing a 1:1 comparison between the architectures.
