AMD Zen 1 Linux Performance Hit From Retbleed, Accumulated CPU Mitigation Impact

Written by Michael Larabel in Software on 20 July 2022. Page 6 of 6. 39 Comments

Those wanting to see even more of these AMD Zen 1 Linux CPU mitigation benchmarks can find all of my raw benchmark data via this OpenBenchmarking.org result page. Especially with Zen 4 right around the corner, if still on AMD Zen 1 it may be time to consider upgrading soon if aiming for peak performance as well as much better power efficiency compared to these older CPUs.
