EPYC 9135 vs Ryzen 9 7945HX3D: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

EPYC 9135

2024

Why buy it

  • +0% higher PassMark.
  • Better for workstations and heavier parallel workloads: 16 cores / 32 threads, plus 128 PCIe lanes vs 28.
  • 357.1% more PCIe lanes (128 vs 28) for storage and expansion-heavy builds.

Trade-offs

  • Worse for gaming: lower average FPS than Ryzen 9 7945HX3D across 50 shared CPU benchmark tests.
  • Launch MSRP is still $1,214 MSRP, while Ryzen 9 7945HX3D mostly shows up through inconsistent older-market listings.
  • 263.6% higher power demand at 200W vs 55W.
  • No integrated graphics, while Ryzen 9 7945HX3D can still boot and troubleshoot without a discrete GPU.

Ryzen 9 7945HX3D

2023

Why buy it
