Quick Answers

So, is Core i5-8260U better than Core i3-10100T?

Yes. Core i5-8260U is the better all-around CPU here. It gives you a 2.3% average FPS lead across 50 shared CPU game tests in our data and 0.2% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i5-8260U is the better pick. According to our tests, it delivers 2.3% 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 i5-8260U is the stronger fit. You are getting 0.2% better PassMark, backed by 4 cores and 8 threads.

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

Core i5-8260U is still the better call for a fresh build. Core i5-8260U comes in at an unclear MSRP at unclear MSRP versus $149 MSRP, and it still gives you a 2.3% average FPS lead across 50 shared CPU game tests in our data. Core i3-10100T 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. At roughly 7,305 PassMark with 4 cores and 8 threads, it only really makes sense as a bare-minimum stopgap or a very constrained existing-platform upgrade.

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

Core i3-10100T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2019). That makes it the safer long-term bet.
