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

Ryzen 7 3780U

2019

Why buy it

  • Draws 15W instead of 80W, a 65W reduction.

Trade-offs

  • Lower PassMark (7,483 vs 7,504).
  • Smaller total L3 cache (4 MB vs 8 MB).
  • Less compelling for workstation-style loads than Xeon E3-1271 v3, which brings 4 cores / 8 threads and 16 PCIe lanes.

Xeon E3-1271 v3

2014

Why buy it

  • +0.3% higher PassMark.
  • +100% larger total L3 cache (8 MB vs 4 MB).
  • Better for workstations and heavier parallel workloads: 4 cores / 8 threads, plus 16 PCIe lanes vs 0.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.

Trade-offs

  • Launch MSRP is still $727 MSRP, while Ryzen 7 3780U mostly shows up through inconsistent older-market listings.
  • 433.3% higher power demand at 80W vs 15W.
