Quick Answers

So, is Pentium SU4100 better than Athlon 64 4000+?

It depends on what you want from the system. For gaming, Athlon 64 4000+ is ahead with a 0.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium SU4100 pulls ahead with 1.5% better PassMark.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Pentium SU4100 is the stronger fit. You are getting 1.5% better PassMark, backed by 2 cores and 2 threads.

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

Pentium SU4100 is the better buy right now. Pentium SU4100 comes in $193 cheaper on MSRP at $289 MSRP versus $482 MSRP, and it still gives you 1.5% better PassMark. The compromise is that Athlon 64 4000+ is still the better pure gaming CPU with a 0.2% average FPS lead across 50 shared CPU game tests in our data. It is also 69.3% better value on MSRP (2.4 vs 1.4 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium SU4100 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2009 vs 2001) 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.
