Quick Answers

So, is Core i3-1315UE better than Core i5-12400F?

It depends on what you want from the system. For gaming, Core i5-12400F is ahead with a 36.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-1315UE pulls ahead with 219.6% better Geekbench multi-core. Core i5-12400F also has the bigger cache pool with 80% larger total L3 cache (18 MB vs 10 MB).

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

For streaming, content creation, and heavier multitasking, Core i3-1315UE is the stronger fit. You are getting 219.6% better Geekbench multi-core, backed by 6 cores and 8 threads.

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

Core i3-1315UE is still the faster CPU overall, but Core i5-12400F is easier to justify if budget matters more than peak performance. Core i3-1315UE comes in 79.3% more expensive on MSRP at $312 MSRP versus $174 MSRP, and it still gives you 219.6% better Geekbench multi-core. The compromise is that Core i5-12400F is still the better pure gaming CPU with a 36.9% average FPS lead across 50 shared CPU game tests in our data. Core i5-12400F is also 289.0% better value on MSRP (112.3 vs 28.9 PassMark/$), 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 i3-1315UE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022) and more multi-core headroom with 6 cores / 8 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
