Which one is better for gaming?

If gaming is the priority, Core i9-13900HX is the better pick here. According to our tests, it delivers 6.5% 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 i9-13900HX is the better fit. You are getting 12.7% better PassMark, backed by 24 cores and 32 threads. It also carries the larger cache pool with 50% larger total L3 cache (36 MB vs 24 MB).

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

Core i9-13900HX is still the faster CPU overall, but Core i5-13600K makes more sense if price matters more than absolute performance. Core i9-13900HX is at an unclear MSRP at unclear MSRP versus $329 MSRP, and it gives you a 6.5% average FPS lead across 50 shared CPU game tests in our data. Core i5-13600K is also 100.0% better value on MSRP (114.5 vs 0.0 PassMark/$), 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 i9-13900HX is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022), 50% larger total L3 cache (36 MB vs 24 MB), and more multi-core headroom with 24 cores / 32 threads instead of 14/20. 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.
