Core i7-9700KF vs Xeon E5-4660 v3: Pros, Cons & Final Verdict

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

Core i7-9700KF

2019

Why buy it

  • Better for gaming: +24.3% higher average FPS across 50 shared CPU benchmark tests.
  • Draws 95W instead of 120W, a 25W reduction.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.

Trade-offs

  • Smaller total L3 cache (12 MB vs 35 MB).
  • Less compelling for workstation-style loads than Xeon E5-4660 v3, which brings 14 cores / 28 threads.
  • Launch MSRP is still $374 MSRP, while Xeon E5-4660 v3 mostly shows up through inconsistent older-market listings.

Xeon E5-4660 v3

2015

Why buy it

  • +191.7% larger total L3 cache (35 MB vs 12 MB).
  • Better for workstations and heavier parallel workloads: 14 cores / 28 threads.

Trade-offs

  • Worse for gaming: lower average FPS than Core i7-9700KF across 50 shared CPU benchmark tests.
  • Lower PassMark (14,167 vs 14,250).
  • 26.3% higher power demand at 120W vs 95W.

Quick Answers

So, is Core i7-9700KF better than Xeon E5-4660 v3?
Not really, because they are built for different jobs. Xeon E5-4660 v3 makes more sense for workstation-style multi-core throughput, while Core i7-9700KF is the more practical desktop choice for gaming, platform cost, and everyday use.
Which one is better for gaming?
If gaming is the priority, Core i7-9700KF is the better pick. According to our tests, it delivers 24.3% more average FPS across 50 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i7-9700KF is the stronger fit. You are getting 0.6% better PassMark, backed by 8 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-9700KF is the better buy right now. Core i7-9700KF comes in at an unclear MSRP at $374 MSRP versus unclear MSRP, and it still gives you a 24.3% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (38.1 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Core i7-9700KF makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2015) and more multi-core headroom with 8 cores / 8 threads instead of 14/28. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
