Quick Answers

So, is Core i5-13400F better than Core i5-1345U?

It depends on what you want from the system. For gaming, Core i5-1345U is ahead with a 2.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-13400F pulls ahead with 75.9% better PassMark. Core i5-13400F also has the bigger cache pool with 66.7% larger total L3 cache (20 MB vs 12 MB).

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

For streaming, content creation, and heavier multitasking, Core i5-13400F is the stronger fit. You are getting 75.9% better PassMark, backed by 10 cores and 16 threads. It also has the larger cache pool with 66.7% larger total L3 cache (20 MB vs 12 MB).

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

Core i5-13400F is the better buy right now. Core i5-13400F comes in at an unclear MSRP at $196 MSRP versus unclear MSRP, and it still gives you 75.9% better PassMark. The compromise is that Core i5-1345U is still the better pure gaming CPU with a 2.1% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (127.7 vs 0.0 PassMark/$), 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 i5-13400F makes more sense long term for 2026 and beyond. You are getting 66.7% larger total L3 cache (20 MB vs 12 MB) and more multi-core headroom with 10 cores / 16 threads instead of 10/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
