Quick Answers

So, is Core i5-6300U better than FX-4350?

It depends on what you want from the system. For gaming, FX-4350 is ahead with a 11.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-6300U pulls ahead with 0.7% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i5-6300U is the stronger fit. You are getting 0.7% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-6300U is still the much better call for a fresh build. Core i5-6300U comes in at an unclear MSRP at unclear MSRP versus $122 MSRP, and it still gives you 0.7% better PassMark. FX-4350 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2013 platform. Even with 100.0% better value on paper (26.1 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on AM3+.

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

Core i5-6300U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2013) 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.
