Testing libgcrypt with the integrated benchmark. Looks to be single-threaded.
Topdown profile shows some blurring, probably from different crypt subtests.
AMD metrics show little floaitng point, a very low amount of frontend stalls and very little L2 access.

Intel metrics show memory accesses are all L1. Interesting to see relative amounts of memory-bound vs cpu-bound flipped between AMD and Intel.
