Quick Answers

So, is Core i7-8700B better than Xeon E5-2650 v3?

Not really, because they are built for different jobs. Xeon E5-2650 v3 makes more sense for workstation-style multi-core throughput, while Core i7-8700B 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 i7-8700B is the better pick. According to our tests, it delivers 3.3% 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, Core i7-8700B is the stronger fit. You are getting 1.1% better PassMark, backed by 6 cores and 12 threads.

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

Core i7-8700B is the better buy right now. Core i7-8700B comes in at an unclear MSRP at $303 MSRP versus unclear MSRP, and it still gives you a 3.3% average FPS lead across 48 shared CPU game tests in our data. It is also 100.0% better value on MSRP (38.9 vs 0.0 PassMark/$), 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 i7-8700B makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2014) and more multi-core headroom with 6 cores / 12 threads instead of 10/20. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
