Quick Answers

So, is Athlon 64 X2 5800+ better than Core i5-520M?

Yes. Athlon 64 X2 5800+ is the better all-around CPU here. It gives you a 4.8% average FPS lead across 50 shared CPU game tests in our data and 1% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Athlon 64 X2 5800+ is the better pick. According to our tests, it delivers 4.8% 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, Athlon 64 X2 5800+ is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 2 threads.

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

Athlon 64 X2 5800+ is still the much better call for a fresh build. Athlon 64 X2 5800+ comes in 2.2% more expensive on MSRP at $230 MSRP versus $225 MSRP, and it still gives you a 4.8% average FPS lead across 50 shared CPU game tests in our data. Core i5-520M only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 1.2% better value on paper (7.7 vs 7.6 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA988.

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

Core i5-520M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2008). That makes it the safer long-term bet.
