Quick Answers

So, is Core i9-10980XE better than Core i7-9700K?
Yes. Core i9-10980XE is the better all-around CPU here. It gives you a 7.6% average FPS lead across 50 shared CPU game tests in our data, 123.6% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Core i9-10980XE is the better pick. According to our tests, it delivers 7.6% 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 i9-10980XE is the stronger fit. You are getting 123.6% better PassMark, backed by 18 cores and 36 threads. It also has the larger cache pool with 106.3% larger total L3 cache (25 MB vs 12 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i9-10980XE is still the much better call for a fresh build. Core i9-10980XE comes in 154.3% more expensive on MSRP at $979 MSRP versus $385 MSRP, and it still gives you a 7.6% average FPS lead across 50 shared CPU game tests in our data. Core i7-9700K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2018 platform. Even with 13.7% better value on paper (37.4 vs 32.9 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.
Which one is more future-proof for 2026 and beyond?
Core i9-10980XE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2018), 106.3% larger total L3 cache (25 MB vs 12 MB), and more multi-core headroom with 18 cores / 36 threads instead of 8/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
