Quick Answers

So, is Core 2 Duo T5200 better than Athlon 64 FX-55?

Yes. Core 2 Duo T5200 is the better all-around CPU here. It gives you a 5.7% average FPS lead across 50 shared CPU game tests in our data, 2.2% 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 2 Duo T5200 is the better pick. According to our tests, it delivers 5.7% 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 2 Duo T5200 is the stronger fit. You are getting 2.2% better PassMark, backed by 2 cores and 2 threads.

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

Core 2 Duo T5200 is still the much better call for a fresh build. Core 2 Duo T5200 comes in at an unclear MSRP at unclear MSRP versus $827 MSRP, and it still gives you a 5.7% average FPS lead across 50 shared CPU game tests in our data. Athlon 64 FX-55 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2004 platform. Even with 100.0% better value on paper (0.8 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on 939.

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

Core 2 Duo T5200 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2006 vs 2004) and more multi-core headroom with 2 cores / 2 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
