Quick Answers

So, is Ryzen 5 PRO 8640U better than Core i9-10900X?

It depends on what you want from the system. For gaming, Ryzen 5 PRO 8640U is ahead with a 1.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i9-10900X pulls ahead with 0% better PassMark. Core i9-10900X also has the bigger cache pool with 20.3% larger total L3 cache (19 MB vs 16 MB).

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

For streaming, content creation, and heavier multitasking, Core i9-10900X is the stronger fit. You are getting 0% better PassMark, backed by 10 cores and 20 threads. It also has the larger cache pool with 20.3% larger total L3 cache (19 MB vs 16 MB).

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

Ryzen 5 PRO 8640U is still the faster CPU overall, but Core i9-10900X is easier to justify if budget matters more than peak performance. Ryzen 5 PRO 8640U comes in at an unclear MSRP at unclear MSRP versus $590 MSRP, and it still gives you a 1.8% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i9-10900X is still stronger for heavier multi-core work with 0% better PassMark. Core i9-10900X is also 100.0% better value on MSRP (37.9 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Ryzen 5 PRO 8640U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2019) and a healthier platform with FP7 and DDR5 instead of LGA2066. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
