Quick Answers

So, is Core i3-10100T better than Core i5-9300HF?

It depends on what you want from the system. For gaming, Core i5-9300HF is ahead with a 1.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-10100T pulls ahead with 0.7% better PassMark. Core i5-9300HF also has the bigger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

For streaming, content creation, and heavier multitasking, Core i3-10100T is the stronger fit. You are getting 0.7% better PassMark, backed by 4 cores and 8 threads.

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

Core i3-10100T is the better buy right now. Core i3-10100T comes in at an unclear MSRP at $149 MSRP versus unclear MSRP, and it still gives you 0.7% better PassMark. The compromise is that Core i5-9300HF is still the better pure gaming CPU with a 1.9% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (49.0 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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) and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
