Quick Answers

So, is Ryzen 5 PRO 7645 better than Xeon Gold 6154?

Not really, because they are built for different jobs. Xeon Gold 6154 makes more sense for workstation-style multi-core throughput, while Ryzen 5 PRO 7645 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 5 PRO 7645 is the better pick. According to our tests, it delivers 9.4% 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 5 PRO 7645 is the stronger fit. You are getting 0.4% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 29.3% larger total L3 cache (32 MB vs 25 MB).

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

Ryzen 5 PRO 7645 is the better buy right now. Ryzen 5 PRO 7645 comes in at an unclear MSRP at $229 MSRP versus unclear MSRP, and it still gives you a 9.4% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (120.4 vs 0.0 PassMark/$), 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 5 PRO 7645 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2017), a healthier platform with AM5 and DDR5 instead of LGA3647, 29.3% larger total L3 cache (32 MB vs 25 MB), and more multi-core headroom with 6 cores / 12 threads instead of 18/36. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
