Quick Answers

So, is Ryzen 7 PRO 4750U better than Core i7-6900K?

It depends on what you want from the system. For gaming, Core i7-6900K is ahead with a 7.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Ryzen 7 PRO 4750U pulls ahead with 0.6% better PassMark. Core i7-6900K also has the bigger cache pool with 150% larger total L3 cache (20 MB vs 8 MB).

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

For streaming, content creation, and heavier multitasking, Ryzen 7 PRO 4750U is the stronger fit. You are getting 0.6% better PassMark, backed by 8 cores and 16 threads.

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

Ryzen 7 PRO 4750U is still the much better call for a fresh build. Ryzen 7 PRO 4750U comes in at an unclear MSRP at unclear MSRP versus $1,089 MSRP, and it still gives you 0.6% better PassMark. Core i7-6900K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2016 platform. Even with 100.0% better value on paper (13.5 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA2011.

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

Ryzen 7 PRO 4750U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2016) and more multi-core headroom with 8 cores / 16 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
