Quick Answers

So, is Ryzen 9 7945HX3D better than Core i5-10400F?

Yes. Ryzen 9 7945HX3D is the better overall CPU here. You are getting a 105.6% average FPS lead across 6 shared CPU game tests in our data, 343.6% 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, Ryzen 9 7945HX3D is the better pick here. According to our tests, it delivers 105.6% more average FPS across 6 shared CPU game tests. It also has a big cache advantage at 128 MB vs 12 MB.

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

For streaming, content creation, and heavier multitasking, Ryzen 9 7945HX3D is the better fit. You are getting 343.6% better PassMark, backed by 16 cores and 32 threads. It also carries the larger cache pool with 966.7% larger total L3 cache (128 MB vs 12 MB).

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

Ryzen 9 7945HX3D is still the faster CPU overall, but Core i5-10400F makes more sense if price matters more than absolute performance. Ryzen 9 7945HX3D is at an unclear MSRP at unclear MSRP versus $160 MSRP, and it gives you a 105.6% average FPS lead across 6 shared CPU game tests in our data. Core i5-10400F is also 100.0% better value on MSRP (81.4 vs 0.0 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.

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

Ryzen 9 7945HX3D is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2020), a healthier platform with FL1 and DDR5 instead of LGA1200, 3D V-Cache and a much larger 128 MB L3 cache instead of 12 MB, and more multi-core headroom with 16 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

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.
