Ryzen 7 PRO 5845

2022

Why buy it

✅Better for gaming: +3.8% higher average FPS across 50 shared CPU benchmark tests.
✅Draws 65W instead of 180W, a 115W reduction.

Trade-offs

❌Smaller total L3 cache (32 MB vs 64 MB).
❌Less compelling for workstation-style loads than EPYC 7551, which brings 32 cores / 64 threads.
❌Launch MSRP is still $300 MSRP, while EPYC 7551 mostly shows up through inconsistent older-market listings.

Quick Answers

So, is Ryzen 7 PRO 5845 better than EPYC 7551?

Not really, because they are built for different jobs. EPYC 7551 makes more sense for workstation-style multi-core throughput, while Ryzen 7 PRO 5845 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Ryzen 7 PRO 5845 is the better pick. According to our tests, it delivers 3.8% 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 7 PRO 5845 is the stronger fit. You are getting 0.8% better PassMark, backed by 8 cores and 16 threads.

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

Ryzen 7 PRO 5845 is the better buy right now. Ryzen 7 PRO 5845 comes in at an unclear MSRP at $300 MSRP versus unclear MSRP, and it still gives you a 3.8% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (86.8 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Ryzen 7 PRO 5845 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2017) and more multi-core headroom with 8 cores / 16 threads instead of 32/64. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
