Quick Answers

So, is Pentium G2120 better than A6-3620?

It depends on what you want from the system. For gaming, Pentium G2120 is ahead with a 1.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, A6-3620 pulls ahead with 0.1% better PassMark.

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

For streaming, content creation, and heavier multitasking, A6-3620 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 4 threads.

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

Pentium G2120 is the better buy right now. Pentium G2120 comes in at an unclear MSRP at $86 MSRP versus unclear MSRP, and it still gives you a 1.8% average FPS lead across 50 shared CPU game tests in our data. The compromise is that A6-3620 is still stronger for heavier multi-core work with 0.1% better PassMark. It is also 100.0% better value on MSRP (21.8 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium G2120 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2011). That makes it the safer long-term bet.
