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

Core i5-4670K

2013

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics 4600, while Core i7-3720QM needs a discrete GPU.
✅Includes a boxed cooler (Yes), unlike Core i7-3720QM.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-3720QM across 50 shared CPU benchmark tests.
❌Lower PassMark (5,584 vs 5,591).
❌Launch MSRP is still $328 MSRP, while Core i7-3720QM mostly shows up through inconsistent older-market listings.
❌86.7% higher power demand at 84W vs 45W.

Core i7-3720QM

2012

Why buy it

✅Better for gaming: +11.1% higher average FPS across 50 shared CPU benchmark tests.
✅Draws 45W instead of 84W, a 39W reduction.

Trade-offs

❌No integrated graphics, while Core i5-4670K can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike Core i5-4670K.

Quick Answers

So, is Core i7-3720QM better than Core i5-4670K?

Yes. Core i7-3720QM is the better all-around CPU here. It gives you a 11.1% average FPS lead across 50 shared CPU game tests in our data and 0.1% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-3720QM is the better pick. According to our tests, it delivers 11.1% 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 i7-3720QM is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 8 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Core i7-3720QM is still the much better call for a fresh build. Core i7-3720QM comes in at an unclear MSRP at unclear MSRP versus $328 MSRP, and it still gives you a 11.1% average FPS lead across 50 shared CPU game tests in our data. Core i5-4670K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2013 platform. Even with 100.0% better value on paper (17.0 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1150.

Which one is more future-proof for 2026 and beyond?

Core i5-4670K makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2012). That makes it the safer long-term bet.
