Quick Answers

So, is Ryzen 9 8945HX better than Core i5-10400F?

Yes. Ryzen 9 8945HX is the better all-around CPU here. It gives you a 45.7% average FPS lead across 50 shared CPU game tests in our data, 308.4% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Ryzen 9 8945HX is the better pick. According to our tests, it delivers 45.7% 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 8945HX is the stronger fit. You are getting 308.4% better PassMark, backed by 16 cores and 32 threads. It also has 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 8945HX is still the much better call for a fresh build. Ryzen 9 8945HX comes in at an unclear MSRP at unclear MSRP versus $160 MSRP, and it still gives you a 45.7% average FPS lead across 50 shared CPU game tests in our data. Core i5-10400F only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2020 platform. Even with 100.0% better value on paper (81.4 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1200.

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

Ryzen 9 8945HX makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2020), a healthier platform with FL1 and DDR5 instead of LGA1200, 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 gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
