Quick Answers

So, is Ryzen 3 3300X better than Core i5-10400F?

Yes. Ryzen 3 3300X is the better overall CPU here. You are getting a 1.3% average FPS lead across 4 shared CPU game tests in our data and 3% better PassMark, which makes it the stronger all-around choice.

Which one is better for gaming?

For gaming, the two CPUs are effectively a wash in the available data.

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

For streaming, content creation, and heavier multitasking, Ryzen 3 3300X is the better fit. You are getting 3% better PassMark, backed by 4 cores and 8 threads. It also carries the larger cache pool with 33.3% larger total L3 cache (16 MB vs 12 MB).

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

Ryzen 3 3300X is the smarter buy today. Ryzen 3 3300X is $40 cheaper on MSRP at $120 MSRP versus $160 MSRP, and it gives you a 1.3% average FPS lead across 4 shared CPU game tests in our data. It is also 37.4% better value on MSRP (111.9 vs 81.4 PassMark/$), 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, but on MSRP alone you would want to find it meaningfully cheaper in real-world listings before that path becomes easy to justify.

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

Ryzen 3 3300X is the safer long-term CPU choice because it gives you more overall headroom and a better platform outlook.

Games Benchmarks

Paired with RTX 4090
