Quick Answers

So, is Core i3-13100T better than Core i5-1235U?

It depends on what you want from the system. For gaming, Core i5-1235U is ahead with a 24.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-13100T pulls ahead with 0.5% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i3-13100T is the stronger fit. You are getting 0.5% better PassMark, backed by 4 cores and 8 threads.

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

Core i3-13100T is the better buy right now. Core i3-13100T comes in at an unclear MSRP at $134 MSRP versus unclear MSRP, and it still gives you 0.5% better PassMark. The compromise is that Core i5-1235U is still the better pure gaming CPU with a 24.4% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (95.5 vs 0.0 PassMark/$), 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 i3-13100T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022) and more multi-core headroom with 4 cores / 8 threads instead of 10/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
