Core i5-5675R vs Core i7-3720QM: Pros, Cons & Final Verdict

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

Core i5-5675R

2015

Why buy it

  • βœ…100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • βœ…Integrated graphics onboard with Iris Pro Graphics 6200, while Core i7-3720QM needs a discrete GPU.

Trade-offs

  • ❌Worse for gaming: lower average FPS than Core i7-3720QM across 50 shared CPU benchmark tests.
  • ❌Lower PassMark (5,564 vs 5,591).
  • ❌Smaller total L3 cache (4 MB vs 6 MB).
  • ❌Launch MSRP is still $339 MSRP, while Core i7-3720QM mostly shows up through inconsistent older-market listings.
  • ❌44.4% higher power demand at 65W vs 45W.

Core i7-3720QM

2012

Why buy it

  • βœ…Better for gaming: +13.5% higher average FPS across 50 shared CPU benchmark tests.
  • βœ…+50% larger total L3 cache (6 MB vs 4 MB).
  • βœ…Draws 45W instead of 65W, a 20W reduction.

Trade-offs

  • ❌No integrated graphics, while Core i5-5675R can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i7-3720QM better than Core i5-5675R?
Yes. Core i7-3720QM is the better all-around CPU here. It gives you a 13.5% average FPS lead across 50 shared CPU game tests in our data and 0.5% 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 13.5% 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 0.5% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 50% larger total L3 cache (6 MB vs 4 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-3720QM is the easy recommendation for a fresh desktop build. Core i7-3720QM comes in at an unclear MSRP at unclear MSRP versus $339 MSRP, and it still gives you a 13.5% average FPS lead across 50 shared CPU game tests in our data. Core i5-5675R only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 13.5% in the shared gaming data.
Which one is more future-proof for 2026 and beyond?
Core i5-5675R makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2012). That makes it the safer long-term bet.
