Quick Answers

So, is FX-4100 better than Core i3-6100U?
It depends on what you want from the system. For gaming, FX-4100 is ahead with a 2.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-6100U pulls ahead with 0% better PassMark. FX-4100 also has the bigger cache pool with 166.7% larger total L3 cache (8 MB vs 3 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i3-6100U is the stronger fit. You are getting 0% better PassMark, backed by 2 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
FX-4100 is the better buy right now. FX-4100 comes in at an unclear MSRP at $115 MSRP versus unclear MSRP, and it still gives you a 2.6% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i3-6100U is still stronger for heavier multi-core work with 0% better PassMark. It is also 100.0% better value on MSRP (22.9 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Core i3-6100U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2011) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
