Quick Answers

So, is Core i5-2520M better than Xeon E5462?

Not really, because they are built for different jobs. Xeon E5462 makes more sense for workstation-style multi-core throughput, while Core i5-2520M is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Core i5-2520M is the better pick. According to our tests, it delivers 0.9% 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 i5-2520M is the stronger fit. You are getting 1.3% 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 $117 cheaper on MSRP at $225 MSRP versus $342 MSRP, and it still gives you a 0.9% average FPS lead across 50 shared CPU game tests in our data. It is also 53.9% better value on MSRP (10.0 vs 6.5 PassMark/$), 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 2007) 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.
