Quick Answers

So, is Core i5-2520M better than Core 2 Quad Q9450?

Yes. Core i5-2520M is the better all-around CPU here. It gives you a 1.4% average FPS lead across 35 shared CPU game tests in our data, 1.5% 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 i5-2520M is the better pick. According to our tests, it delivers 1.4% more average FPS across 35 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core i5-2520M is the stronger fit. You are getting 1.5% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-2520M is the better buy right now. Core i5-2520M comes in $91 cheaper on MSRP at $225 MSRP versus $316 MSRP, and it still gives you a 1.4% average FPS lead across 35 shared CPU game tests in our data. It is also 42.5% better value on MSRP (10.0 vs 7.0 PassMark/$), 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 i5-2520M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2008) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
