Quick Answers

So, is Xeon E5-2679 v4 better than Core i7-9700K?

Not in a simple one-size-fits-all way. Xeon E5-2679 v4 makes more sense for workstation-style multi-core throughput, while Core i7-9700K is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.

Which one is better for gaming?

If gaming is the priority, Xeon E5-2679 v4 is the better pick here. According to our tests, it delivers 30.2% more average FPS across 4 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Xeon E5-2679 v4 is the better fit. You are getting 67.6% better PassMark, backed by 20 cores and 40 threads. It also carries the larger cache pool with 316.7% larger total L3 cache (50 MB vs 12 MB).

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

Xeon E5-2679 v4 is the smarter buy by a wide margin for a fresh build. Xeon E5-2679 v4 is 601.8% more expensive on MSRP at $2,702 MSRP versus $385 MSRP, and it gives you a 30.2% average FPS lead across 4 shared CPU game tests in our data. Core i7-9700K only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2018 platform. Even with 318.7% better value on paper (37.4 vs 8.9 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Core i7-9700K is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2016). That makes it the safer long-term pick.
