Quick Answers

So, is Pentium Gold G5600 better than FX-6120?

It depends on what you want from the system. For gaming, Pentium Gold G5600 is ahead with a 3.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, FX-6120 pulls ahead with 0.2% better PassMark. FX-6120 also has the bigger cache pool with 100% larger total L3 cache (8 MB vs 4 MB).

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

For streaming, content creation, and heavier multitasking, FX-6120 is the stronger fit. You are getting 0.2% better PassMark, backed by 6 cores and 6 threads. It also has the larger cache pool with 100% larger total L3 cache (8 MB vs 4 MB).

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

Pentium Gold G5600 is still the much better call for a fresh build. Pentium Gold G5600 comes in at an unclear MSRP at unclear MSRP versus $188 MSRP, and it still gives you a 3.6% average FPS lead across 50 shared CPU game tests in our data. FX-6120 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 100.0% better value on paper (20.5 vs 0.0 PassMark/$), 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?

Pentium Gold G5600 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2012). That makes it the safer long-term bet.
