Yes. Ryzen 9 5900XT is the better overall CPU here. You are getting a 38.6% average FPS lead across 50 shared CPU game tests in our data, 168.6% better Cinebench R23 multi-core, 238.5% higher 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, Ryzen 9 5900XT is the better pick here. According to our tests, it delivers 38.6% 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, Ryzen 9 5900XT is the better fit. You are getting 168.6% better Cinebench R23 multi-core, backed by 16 cores and 32 threads. It also carries the larger cache pool with 433.3% larger total L3 cache (64 MB vs 12 MB).

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

Ryzen 9 5900XT is the smarter buy today. Ryzen 9 5900XT is 118.1% more expensive on MSRP at $349 MSRP versus $160 MSRP, and it gives you a 38.6% average FPS lead across 50 shared CPU game tests in our data. It is also 55.2% better value on MSRP (126.4 vs 81.4 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play 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?

Ryzen 9 5900XT is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2020), 433.3% larger total L3 cache (64 MB vs 12 MB), and more multi-core headroom with 16 cores / 32 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.
