Yes. Core i9-13900T is the better overall CPU here. You are getting a 56.5% average FPS lead across 3 shared CPU game tests in our data, 228% better PassMark, and the stronger long-term platform, which makes it the stronger all-around choice.

Which one is better for gaming?

If gaming is the priority, Core i9-13900T is the better pick here. According to our tests, it delivers 56.5% more average FPS across 3 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Core i9-13900T is the better fit. You are getting 228% better PassMark, backed by 24 cores and 32 threads. It also carries the larger cache pool with 200% larger total L3 cache (36 MB vs 12 MB).

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

Core i9-13900T is still the faster CPU overall, but Core i5-10400F makes more sense if price matters more than absolute performance. Core i9-13900T is 243.1% more expensive on MSRP at $549 MSRP versus $160 MSRP, and it gives you a 56.5% average FPS lead across 3 shared CPU game tests in our data. Core i5-10400F is also 4.6% better value on MSRP (81.4 vs 77.8 PassMark/$), which is why it is easier to justify for price-conscious builds on paper. That said, if you already own a compatible LGA1200 + DDR4 setup, Core i5-10400F can still make sense as a platform-matched option because it avoids a motherboard and RAM swap.

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

Core i9-13900T is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2020), a healthier platform with LGA1700 and DDR5 instead of LGA1200, 200% larger total L3 cache (36 MB vs 12 MB), and more multi-core headroom with 24 cores / 32 threads instead of 6/12. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

Games Benchmarks

Paired with RTX 4090
