Quick Answers

So, is Xeon W3520 better than Xeon X5492?

It depends on what you want from the system. For gaming, Xeon X5492 is ahead with a 3.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon W3520 pulls ahead with 1% better PassMark. Xeon X5492 also has the bigger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).

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

For streaming, content creation, and heavier multitasking, Xeon W3520 is the stronger fit. You are getting 1% better PassMark, backed by 4 cores and 8 threads.

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

Xeon W3520 is the better buy right now. Xeon W3520 comes in at an unclear MSRP at $284 MSRP versus unclear MSRP, and it still gives you 1% better PassMark. The compromise is that Xeon X5492 is still the better pure gaming CPU with a 3.6% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (10.4 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Xeon W3520 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2009 vs 2008). That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
