Quick Answers

So, is Ryzen 9 PRO 7945 better than Ryzen 7 3700X?
Yes. Ryzen 9 PRO 7945 is the better overall CPU here. You are getting a 11.4% average FPS lead across 36 shared CPU game tests in our data, 108.8% 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 PRO 7945 is the better pick here. According to our tests, it delivers 11.4% more average FPS across 36 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Ryzen 9 PRO 7945 is the better fit. You are getting 108.8% better PassMark, backed by 12 cores and 24 threads. It also carries the larger cache pool with 100% larger total L3 cache (64 MB vs 32 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Ryzen 9 PRO 7945 is the smarter buy today. Ryzen 9 PRO 7945 is 24.3% more expensive on MSRP at $409 MSRP versus $329 MSRP, and it gives you a 11.4% average FPS lead across 36 shared CPU game tests in our data. It is also 67.9% better value on MSRP (114.5 vs 68.2 PassMark/$), 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 AM4 + DDR4 setup, Ryzen 7 3700X 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 PRO 7945 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2019), a healthier platform with AM5 and DDR5 instead of AM4, 100% larger total L3 cache (64 MB vs 32 MB), and more multi-core headroom with 12 cores / 24 threads instead of 8/16. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

Games Benchmarks

Paired with RTX 4090
