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

Core i7-3687U

2013

Why buy it

  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with HD Graphics 4000, while FX-4100 needs a discrete GPU.

Trade-offs

  • Lower PassMark (2,621 vs 2,630).
  • Smaller total L3 cache (4 MB vs 8 MB).
  • 438.9% higher power demand at 512W vs 95W.

FX-4100

2011

Why buy it

  • +100% larger total L3 cache (8 MB vs 4 MB).
  • Draws 95W instead of 512W, a 417W reduction.

Trade-offs

  • Launch MSRP is still $115 MSRP, while Core i7-3687U mostly shows up through inconsistent older-market listings.
  • No integrated graphics, while Core i7-3687U can still boot and troubleshoot without a discrete GPU.
