Does MHz Still Matter?
To provide VMs of any size, we slice bare metal into smaller VMs, sometimes even 1 vCPU. So, the performance of one fast core matters a lot. We evaluated new servers from Hetzner with AMD EPYC and Ryzen CPUs.
The previous benchmark provided a general view of the performance difference, but identifying bottlenecks requires a controlled setup. Moving the same workloads from EPYC 9454P to Ryzen 9 7950X3D delivered a steady 32–38% improvement, and IO‑heavy cases often gained more because our encrypted storage path puts extra work on the CPU. We can conclude that one faster core lifts short jobs, reduces IO wait, and keeps NVMe busier.
