Quick Answers

So, is A4 PRO-3340B better than Athlon X2 QL-66?

Yes. A4 PRO-3340B is the better all-around CPU here. It gives you a 2.2% average FPS lead across 50 shared CPU game tests in our data, 0.8% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

For gaming, this matchup is basically a tie in the data we have.

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

For streaming, content creation, and heavier multitasking, A4 PRO-3340B is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 4 threads.

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

A4 PRO-3340B is still the much better call for a fresh build. A4 PRO-3340B comes in at an unclear MSRP at unclear MSRP versus $150 MSRP, and it still gives you a 2.2% average FPS lead across 50 shared CPU game tests in our data. Athlon X2 QL-66 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 100.0% better value on paper (11.3 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on S1g2.

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

A4 PRO-3340B makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2009) and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
