Quick Answers

So, is Core 2 Duo T5600 better than Xeon 5150?

Not really, because they are built for different jobs. Xeon 5150 makes more sense for workstation-style multi-core throughput, while Core 2 Duo T5600 is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Core 2 Duo T5600 is the stronger fit. You are getting 0.3% better PassMark, backed by 2 cores and 2 threads.

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

Core 2 Duo T5600 is the better buy right now. Core 2 Duo T5600 comes in at an unclear MSRP at $241 MSRP versus unclear MSRP, and it still gives you 0.3% better PassMark. The compromise is that Xeon 5150 is still the better pure gaming CPU with a 0.6% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (6.5 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core 2 Duo T5600 makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
