Quick Answers

So, is Core i3-10105T better than Core i5-9400H?

It depends on what you want from the system. For gaming, Core i5-9400H is ahead with a 6.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-10105T pulls ahead with 0.3% better PassMark. Core i5-9400H 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 i3-10105T is the stronger fit. You are getting 0.3% better PassMark, backed by 4 cores and 8 threads.

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

Core i3-10105T is the better buy right now. Core i3-10105T comes in $60 cheaper on MSRP at $122 MSRP versus $182 MSRP, and it still gives you 0.3% better PassMark. The compromise is that Core i5-9400H is still the better pure gaming CPU with a 6.7% average FPS lead across 50 shared CPU game tests in our data. It is also 49.6% better value on MSRP (64.1 vs 42.8 PassMark/$), 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 i3-10105T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 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.
