Quick Answers

So, is Xeon E5-2609 better than Core 2 Duo P8800?

Not really, because they are built for different jobs. Xeon E5-2609 makes more sense for workstation-style multi-core throughput, while Core 2 Duo P8800 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Xeon E5-2609 is the better pick. According to our tests, it delivers 5.9% 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, Xeon E5-2609 is the stronger fit. You are getting 0.4% better PassMark, backed by 4 cores and 4 threads. It also has the larger cache pool with 233.3% larger total L3 cache (10 MB vs 3 MB).

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

Xeon E5-2609 still makes the most sense overall. Xeon E5-2609 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 5.9% average FPS lead across 50 shared CPU game tests in our data.

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

Xeon E5-2609 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2009), 233.3% larger total L3 cache (10 MB vs 3 MB), and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
