Quick Answers

So, is Core i5-13400F better than Core i5-1335U?

Yes. Core i5-13400F is the better all-around CPU here. It gives you a 2.7% average FPS lead across 50 shared CPU game tests in our data, 80.6% better Cinebench R23 multi-core, 77.6% higher PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i5-13400F is the better pick. According to our tests, it delivers 2.7% more average FPS across 50 shared CPU game tests.

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 80.6% better Cinebench R23 multi-core, 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 $196 MSRP versus unclear MSRP, and it still gives you a 2.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (127.7 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

Which one is more future-proof for 2026 and beyond?
