Quick Answers

So, is Mobile Athlon 64 2800+ better than Celeron 540?

Yes. Mobile Athlon 64 2800+ is the better all-around CPU here. It gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data and 2.9% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Mobile Athlon 64 2800+ is the better pick. According to our tests, it delivers 0.2% 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 Athlon 64 2800+ is the stronger fit. You are getting 2.9% better PassMark, backed by 1 cores and 1 threads.

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

Mobile Athlon 64 2800+ is still the much better call for a fresh build. Mobile Athlon 64 2800+ comes in at an unclear MSRP at unclear MSRP versus $86 MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. Celeron 540 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2007 platform. Even with 100.0% better value on paper (4.7 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA478.

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

Celeron 540 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2007 vs 2004). That makes it the safer long-term bet.
