Quick Answers

So, is Core i5-1335UE better than Core i5-10400F?

It depends on what you want from the system. For gaming, Core i5-1335UE is ahead with a 1.5% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-10400F pulls ahead with 19.5% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i5-10400F is the stronger fit. You are getting 19.5% better PassMark, backed by 6 cores and 12 threads.

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

Core i5-1335UE is still the faster CPU overall, but Core i5-10400F is easier to justify if budget matters more than peak performance. Core i5-1335UE comes in 95.0% more expensive on MSRP at $312 MSRP versus $160 MSRP, and it still gives you a 1.5% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i5-10400F is still stronger for heavier multi-core work with 19.5% better PassMark. Core i5-10400F is also 133.0% better value on MSRP (81.4 vs 34.9 PassMark/$), 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 i5-1335UE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2020) and a healthier platform with FCBGA1744 and DDR5 instead of LGA1200. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
