Trade-offs

  • 89.7% HIGHER MSRP
    $385 MSRPvs$203 MSRP
  • 18.8% higher power demand at 95W vs 80W.

Xeon E3-1220 v3

2013

Why buy it

  • Costs $182 less on MSRP ($203 MSRP vs $385 MSRP).
  • Draws 80W instead of 95W, a 15W reduction.

Trade-offs

  • Worse for gaming: lower average FPS than Core i7-9700K across 50 shared CPU benchmark tests.
  • Lower PassMark (5,178 vs 14,397).
  • Smaller total L3 cache (8 MB vs 12 MB).

Quick Answers

So, is Core i7-9700K better than Xeon E3-1220 v3?
Not really, because they are built for different jobs. Xeon E3-1220 v3 makes more sense for workstation-style multi-core throughput, while Core i7-9700K 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 i7-9700K is the better pick. According to our tests, it delivers 153.0% 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 i7-9700K is the stronger fit. You are getting 178% better PassMark, backed by 8 cores and 8 threads. It also has the larger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-9700K is the better buy right now. Core i7-9700K comes in 89.7% more expensive on MSRP at $385 MSRP versus $203 MSRP, and it still gives you a 153.0% average FPS lead across 50 shared CPU game tests in our data. It is also 46.6% better value on MSRP (37.4 vs 25.5 PassMark/$), 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 i7-9700K makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2013), 50% larger total L3 cache (12 MB vs 8 MB), and more multi-core headroom with 8 cores / 8 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
