Quick Answers

So, is Mobile Pentium 4 2.80 better than Athlon 64 2800+?

Yes. Mobile Pentium 4 2.80 is the better all-around CPU here. It gives you a 9.8% average FPS lead across 50 shared CPU game tests in our data and 1.9% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Mobile Pentium 4 2.80 is the better pick. According to our tests, it delivers 9.8% 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, Mobile Pentium 4 2.80 is the stronger fit. You are getting 1.9% better PassMark, backed by 1 cores and 2 threads.

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

Mobile Pentium 4 2.80 is still the much better call for a fresh build. Mobile Pentium 4 2.80 comes in at an unclear MSRP at unclear MSRP versus $178 MSRP, and it still gives you a 9.8% average FPS lead across 50 shared CPU game tests in our data. Athlon 64 2800+ only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2004 platform. Even with 100.0% better value on paper (2.4 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on 754.

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

Athlon 64 2800+ makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2004 vs 2003). That makes it the safer long-term bet.
