Different benchmarks favor different processors… Here's another one, now multi-threaded My quick run of `sysbench cpu` (something with prime numbers) shows: Skylark 3.3GHz 32core (at Packet; Ubuntu 18.04): events per second: 44287.87 Zen 3.85GHz 8c16t (my desktop; FreeBSD 13-CURRENT): events per second: 14632.61 And with a single thread, 1386.24 vs 1740.91. Divided by clock speed, it's about 93% of the performance.
