Quick Answers

So, is Core i7-9700K better than Core i3-10105T?
Yes. Core i7-9700K is the better all-around CPU here. It gives you a 85.7% average FPS lead across 50 shared CPU game tests in our data and 84.2% better PassMark, 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 85.7% 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 84.2% better PassMark, backed by 8 cores and 8 threads. It also has the larger cache pool with 100% larger total L3 cache (12 MB vs 6 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-9700K is still the better call for a fresh build. Core i7-9700K comes in 215.6% more expensive on MSRP at $385 MSRP versus $122 MSRP, and it still gives you a 85.7% average FPS lead across 50 shared CPU game tests in our data. Core i3-10105T only looks stronger on raw value math because it is so cheap, but its absolute performance tier is too low to be the better recommendation now. Giving up that much average FPS in the shared benchmark data is simply too much for that budget trade-off.
Which one is more future-proof for 2026 and beyond?
Core i3-10105T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2018). That makes it the safer long-term bet.
