Ryzen 5 3450U vs Xeon E3-1275 v2: Pros, Cons & Final Verdict

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

Ryzen 5 3450U

2020

Why buy it

  • Draws 2W instead of 77W, a 75W reduction.

Trade-offs

  • Worse for gaming: lower average FPS than Xeon E3-1275 v2 across 50 shared CPU benchmark tests.
  • Lower PassMark (6,550 vs 6,644).
  • Smaller total L3 cache (4 MB vs 8 MB).
  • Less compelling for workstation-style loads than Xeon E3-1275 v2, which brings 4 cores / 8 threads and 20 PCIe lanes.
  • No integrated graphics, while Xeon E3-1275 v2 can still boot and troubleshoot without a discrete GPU.

Xeon E3-1275 v2

2012

Why buy it

  • Better for gaming: +4.2% higher average FPS across 50 shared CPU benchmark tests.
  • +100% larger total L3 cache (8 MB vs 4 MB).
  • Better for workstations and heavier parallel workloads: 4 cores / 8 threads, plus 20 PCIe lanes vs 0.
  • 100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with Intel HD Graphics P4000, while Ryzen 5 3450U needs a discrete GPU.

Trade-offs

  • Launch MSRP is still $426 MSRP, while Ryzen 5 3450U mostly shows up through inconsistent older-market listings.
  • 3750% higher power demand at 77W vs 2W.
