Quick Answers

So, is Ryzen 7 3700X better than Xeon X5660?

Not really, because they are built for different jobs. Xeon X5660 makes more sense for workstation-style multi-core throughput, while Ryzen 7 3700X is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Ryzen 7 3700X is the better pick. According to our tests, it delivers 114.4% more average FPS across 48 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Ryzen 7 3700X is the stronger fit. You are getting 275.1% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 166.7% larger total L3 cache (32 MB vs 12 MB).

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

Ryzen 7 3700X is the better buy right now. Ryzen 7 3700X comes in $890 cheaper on MSRP at $329 MSRP versus $1,219 MSRP, and it still gives you a 114.4% average FPS lead across 48 shared CPU game tests in our data. It is also 1290.0% better value on MSRP (68.2 vs 4.9 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Ryzen 7 3700X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2010), 166.7% larger total L3 cache (32 MB vs 12 MB), and more multi-core headroom with 8 cores / 16 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
