Quick Answers

So, is Ryzen 5 PRO 7645 better than Core i5-12400F?

Yes. Ryzen 5 PRO 7645 is the better overall CPU here. You are getting a 29.8% average FPS lead across 6 shared CPU game tests in our data, 41.1% 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 5 PRO 7645 is the better pick here. According to our tests, it delivers 29.8% more average FPS across 6 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Ryzen 5 PRO 7645 is the better fit. You are getting 41.1% better PassMark, backed by 6 cores and 12 threads. It also carries the larger cache pool with 77.8% larger total L3 cache (32 MB vs 18 MB).

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

Ryzen 5 PRO 7645 is the smarter buy today. Ryzen 5 PRO 7645 is 31.6% more expensive on MSRP at $229 MSRP versus $174 MSRP, and it gives you a 29.8% average FPS lead across 6 shared CPU game tests in our data. It is also 7.2% better value on MSRP (120.4 vs 112.3 PassMark/$), 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 LGA1700 + DDR5 setup, Core i5-12400F 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 5 PRO 7645 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022), 77.8% larger total L3 cache (32 MB vs 18 MB), and more multi-core headroom with 6 cores / 12 threads instead of 6/12. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.
