Quick Answers

So, is Core i5-1335U better than Core i5-12400F?

It depends on what you want from the system. For gaming, Core i5-1335U is ahead with a 1.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-12400F pulls ahead with 37.9% better Cinebench R23 multi-core. Core i5-12400F also has the bigger cache pool with 50% larger total L3 cache (18 MB vs 12 MB).

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

For streaming, content creation, and heavier multitasking, Core i5-12400F is the stronger fit. You are getting 37.9% better Cinebench R23 multi-core, backed by 6 cores and 12 threads. It also has the larger cache pool with 50% larger total L3 cache (18 MB vs 12 MB).

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

Core i5-1335U is still the faster CPU overall, but Core i5-12400F is easier to justify if budget matters more than peak performance. Core i5-1335U comes in at an unclear MSRP at unclear MSRP versus $174 MSRP, and it still gives you a 1.7% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i5-12400F is still stronger for heavier multi-core work with 37.9% better Cinebench R23 multi-core. Core i5-12400F is also 100.0% better value on MSRP (112.3 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core i5-1335U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022). That makes it the safer long-term bet.
