Quick Answers

So, is Core i5-10400T better than Core i7-8750H?

It depends on what you want from the system. For gaming, Core i7-8750H is ahead with a 8.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-10400T pulls ahead with 0.2% better PassMark. Core i5-10400T also has the bigger cache pool with 33.3% larger total L3 cache (12 MB vs 9 MB).

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

For streaming, content creation, and heavier multitasking, Core i5-10400T is the stronger fit. You are getting 0.2% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 33.3% larger total L3 cache (12 MB vs 9 MB).

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

Core i5-10400T is the better buy right now. Core i5-10400T comes in at an unclear MSRP at $182 MSRP versus unclear MSRP, and it still gives you 0.2% better PassMark. The compromise is that Core i7-8750H is still the better pure gaming CPU with a 8.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (53.8 vs 0.0 PassMark/$), 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 i5-10400T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2018), 33.3% larger total L3 cache (12 MB vs 9 MB), and more multi-core headroom with 6 cores / 12 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
