Quick Answers

So, is Core i5-7640X better than Xeon W3680?

Not really, because they are built for different jobs. Xeon W3680 makes more sense for workstation-style multi-core throughput, while Core i5-7640X 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 i5-7640X is the better pick. According to our tests, it delivers 1.3% 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 i5-7640X is the stronger fit. You are getting 0.5% better PassMark, backed by 4 cores and 4 threads.

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

Core i5-7640X is the better buy right now. Core i5-7640X comes in $345 cheaper on MSRP at $249 MSRP versus $594 MSRP, and it still gives you a 1.3% average FPS lead across 50 shared CPU game tests in our data. It is also 139.7% better value on MSRP (28.4 vs 11.8 PassMark/$), 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 i5-7640X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2010) and more multi-core headroom with 4 cores / 4 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
