Quick Answers

So, is Opteron 254 better than Pentium SU4100?

Not really, because they are built for different jobs. Opteron 254 makes more sense for workstation-style multi-core throughput, while Pentium SU4100 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Opteron 254 is the better pick. According to our tests, it delivers 0.1% 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, Opteron 254 is the stronger fit. You are getting 0.7% better PassMark, backed by 1 cores and 1 threads.

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

Opteron 254 is the easy recommendation for a fresh desktop build. Opteron 254 comes in at an unclear MSRP at unclear MSRP versus $289 MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data. Pentium SU4100 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 0.1% in the shared gaming data.

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 2005). That makes it the safer long-term bet.
