Core i5-580M

2010

Why buy it

✅Draws 35W instead of 512W, a 477W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics, while Core M-5Y71 needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (3 MB vs 4 MB).

Core M-5Y71

2014

Why buy it

✅+33.3% larger total L3 cache (4 MB vs 3 MB).

Trade-offs

❌Lower PassMark (1,975 vs 1,983).
❌Launch MSRP is still $281 MSRP, while Core i5-580M mostly shows up through inconsistent older-market listings.
❌1362.9% higher power demand at 512W vs 35W.
❌No integrated graphics, while Core i5-580M can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i5-580M better than Core M-5Y71?

Yes. Core i5-580M is the better all-around CPU here. It gives you a 2.8% average FPS lead across 50 shared CPU game tests in our data and 0.4% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i5-580M is the better pick. According to our tests, it delivers 2.8% 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 i5-580M is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-580M is the easy recommendation for a fresh desktop build. Core i5-580M comes in at an unclear MSRP at unclear MSRP versus $281 MSRP, and it still gives you a 2.8% average FPS lead across 50 shared CPU game tests in our data. Core M-5Y71 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 2.8% in the shared gaming data.

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

Core M-5Y71 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2010) and 33.3% larger total L3 cache (4 MB vs 3 MB). That makes it the safer long-term bet.
