Quick Answers

So, is Core i7-8809G better than Xeon E5-2665?

Not really, because they are built for different jobs. Xeon E5-2665 makes more sense for workstation-style multi-core throughput, while Core i7-8809G is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Core i7-8809G is the better pick. According to our tests, it delivers 0.5% 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, Core i7-8809G is the stronger fit. You are getting 1.9% better PassMark, backed by 4 cores and 8 threads.

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

Core i7-8809G is the better buy right now. Core i7-8809G comes in at an unclear MSRP at $450 MSRP versus unclear MSRP, and it still gives you a 0.5% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (18.8 vs 0.0 PassMark/$), 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 i7-8809G makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2012) and more multi-core headroom with 4 cores / 8 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
