Quick Answers

So, is Ryzen 5 PRO 5655GE better than Core i9-9900K?

It depends on what you want from the system. For gaming, Core i9-9900K is ahead with a 29.5% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Ryzen 5 PRO 5655GE pulls ahead with 0.3% better PassMark.

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

For streaming, content creation, and heavier multitasking, Ryzen 5 PRO 5655GE is the stronger fit. You are getting 0.3% better PassMark, backed by 6 cores and 12 threads.

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

Ryzen 5 PRO 5655GE is the better buy right now. Ryzen 5 PRO 5655GE comes in $342 cheaper on MSRP at $146 MSRP versus $488 MSRP, and it still gives you 0.3% better PassMark. The compromise is that Core i9-9900K is still the better pure gaming CPU with a 29.5% average FPS lead across 50 shared CPU game tests in our data. It is also 235.4% better value on MSRP (124.4 vs 37.1 PassMark/$), 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 5655GE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2018) and more multi-core headroom with 6 cores / 12 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
