Core i7-3720QM vs Core i7-9700K: Pros, Cons & Final Verdict

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

Core i7-3720QM

2012

Why buy it

  • Draws 45W instead of 95W, a 50W reduction.

Trade-offs

  • Worse for gaming: lower average FPS than Core i7-9700K across 50 shared CPU benchmark tests.
  • Lower PassMark (5,591 vs 14,397).
  • Smaller total L3 cache (6 MB vs 12 MB).
  • No integrated graphics, while Core i7-9700K can still boot and troubleshoot without a discrete GPU.

Core i7-9700K

2018

Why buy it

  • Better for gaming: +105.8% higher average FPS across 50 shared CPU benchmark tests.
  • +100% larger total L3 cache (12 MB vs 6 MB).
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with UHD Graphics 630, while Core i7-3720QM needs a discrete GPU.

Trade-offs

  • Launch MSRP is still $385 MSRP, while Core i7-3720QM mostly shows up through inconsistent older-market listings.
  • 111.1% higher power demand at 95W vs 45W.

Quick Answers

So, is Core i7-9700K better than Core i7-3720QM?
Yes. Core i7-9700K is the better all-around CPU here. It gives you a 105.8% average FPS lead across 50 shared CPU game tests in our data, 157.5% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Core i7-9700K is the better pick. According to our tests, it delivers 105.8% 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 157.5% better PassMark, backed by 8 cores and 8 threads. It also has the larger cache pool with 100% larger total L3 cache (12 MB vs 6 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 at an unclear MSRP at $385 MSRP versus unclear MSRP, and it still gives you a 105.8% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (37.4 vs 0.0 PassMark/$), 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 i7-9700K makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2012), 100% larger total L3 cache (12 MB vs 6 MB), and more multi-core headroom with 8 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
