Core i7-3820 vs Xeon E5-2430: Pros, Cons & Final Verdict

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

Core i7-3820

2012

Why buy it

  • 100+% more PCIe lanes (40 vs 0) for storage and expansion-heavy builds.

Trade-offs

  • Smaller total L3 cache (10 MB vs 15 MB).
  • Less compelling for workstation-style loads than Xeon E5-2430, which brings 6 cores / 12 threads.
  • Launch MSRP is still $286 MSRP, while Xeon E5-2430 mostly shows up through inconsistent older-market listings.
  • 36.8% higher power demand at 130W vs 95W.

Xeon E5-2430

2012

Why buy it

  • +50% larger total L3 cache (15 MB vs 10 MB).
  • Better for workstations and heavier parallel workloads: 6 cores / 12 threads.
  • Draws 95W instead of 130W, a 35W reduction.

Trade-offs

  • Lower PassMark (5,755 vs 5,787).

Quick Answers

So, is Core i7-3820 better than Xeon E5-2430?
Not really, because they are built for different jobs. Xeon E5-2430 makes more sense for workstation-style multi-core throughput, while Core i7-3820 is the more practical desktop choice for gaming, platform cost, and everyday use.
