Which one is the smarter buy today, not just the cheaper CPU?
Core i7-11700K is still the faster CPU overall, but Core i5-10400F makes more sense if price matters more than absolute performance. Core i7-11700K is 149.4% more expensive on MSRP at $399 MSRP versus $160 MSRP, and it gives you a 76.6% average FPS lead across 4 shared CPU game tests in our data. Core i5-10400F is also 33.4% better value on MSRP (81.4 vs 61.1 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.
Which one is more future-proof for 2026 and beyond?
Core i7-11700K is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2020), 33.3% larger total L3 cache (16 MB vs 12 MB), and more multi-core headroom with 8 cores / 16 threads instead of 6/12. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
