Quick Answers

So, is Pentium G645 better than A4-6300?

It depends on what you want from the system. For gaming, A4-6300 is ahead with a 2.3% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium G645 pulls ahead with 1% better PassMark.

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

For streaming, content creation, and heavier multitasking, Pentium G645 is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 2 threads.

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

Pentium G645 is the better buy right now. Pentium G645 comes in at an unclear MSRP at $80 MSRP versus unclear MSRP, and it still gives you 1% better PassMark. The compromise is that A4-6300 is still the better pure gaming CPU with a 2.3% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (18.1 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

A4-6300 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2012). That makes it the safer long-term bet.
