Quick Answers

So, is Core i7-9700K better than Core i5-8600T?

Yes. Core i7-9700K is the better all-around CPU here. It gives you a 83.0% average FPS lead across 50 shared CPU game tests in our data, 56.5% 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 i7-9700K is the better pick. According to our tests, it delivers 83.0% 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 i7-9700K is the stronger fit. You are getting 56.5% better PassMark, backed by 8 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (12 MB vs 9 MB).

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

Core i7-9700K is still the much better call for a fresh build. Core i7-9700K comes in 80.8% more expensive on MSRP at $385 MSRP versus $213 MSRP, and it still gives you a 83.0% average FPS lead across 50 shared CPU game tests in our data. Core i5-8600T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2018 platform. Even with 15.5% better value on paper (43.2 vs 37.4 PassMark/$), 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 i7-9700K makes more sense long term for 2026 and beyond. You are getting 33.3% larger total L3 cache (12 MB vs 9 MB) and more multi-core headroom with 8 cores / 8 threads instead of 6/6. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
