Quick Answers

So, is Core i5-1340P better than Core i5-10400F?

Yes. Core i5-1340P is the better all-around CPU here. It gives you a 27.6% average FPS lead across 50 shared CPU game tests in our data, 31.6% better Cinebench R23 multi-core, 42.7% 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 i5-1340P is the better pick. According to our tests, it delivers 27.6% 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 i5-1340P is the stronger fit. You are getting 31.6% better Cinebench R23 multi-core, backed by 12 cores and 16 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 i5-1340P is still the faster CPU overall, but Core i5-10400F is easier to justify if budget matters more than peak performance. Core i5-1340P comes in at an unclear MSRP at unclear MSRP versus $160 MSRP, and it still gives you a 27.6% average FPS lead across 50 shared CPU game tests in our data. Core i5-10400F is also 100.0% better value on MSRP (81.4 vs 0.0 PassMark/$), 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 i5-1340P makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2020), a healthier platform with FCBGA1744 and DDR5 instead of LGA1200, 50% larger total L3 cache (18 MB vs 12 MB), and more multi-core headroom with 12 cores / 16 threads instead of 6/12. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
