Ryzen 9 PRO 5945

2022

Why buy it

✅Better for gaming: +10.2% higher average FPS across 24 shared CPU benchmark tests.
✅+79% larger total L3 cache (64 MB vs 36 MB).
✅Draws 65W instead of 165W, a 100W reduction.

Trade-offs

❌Lower Cinebench R23 multi-core (23,200 vs 30,500).
❌Less compelling for workstation-style loads than Xeon Platinum 8260M, which brings 24 cores / 48 threads and 48 PCIe lanes.
❌No AVX-512 support for niche heavy compute workloads where it can matter.

Xeon Platinum 8260M

2019

Why buy it

✅+31.5% higher Cinebench R23 multi-core.
✅Better for workstations and heavier parallel workloads: 24 cores / 48 threads, plus 48 PCIe lanes vs 20.
✅140% more PCIe lanes (48 vs 20) for storage and expansion-heavy builds.

Trade-offs

❌Worse for gaming: lower average FPS than Ryzen 9 PRO 5945 across 24 shared CPU benchmark tests.
❌Smaller total L3 cache (36 MB vs 64 MB).
❌Launch MSRP is still $7,705 MSRP, while Ryzen 9 PRO 5945 mostly shows up through inconsistent older-market listings.
❌153.8% higher power demand at 165W vs 65W.
