Quick Answers

So, is Athlon II M340 better than A6-5345M?

It depends on what you want from the system. For gaming, Athlon II M340 is ahead with 243.2% stronger Geekbench single-core performance. For rendering, compiling, streaming, and heavier multitasking, A6-5345M pulls ahead with 0.6% better PassMark.

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

For streaming, content creation, and heavier multitasking, A6-5345M is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 2 threads.

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

Athlon II M340 is the better buy right now. Athlon II M340 comes in at an unclear MSRP at $80 MSRP versus unclear MSRP, and it still gives you 243.2% stronger Geekbench single-core performance. The compromise is that A6-5345M is still stronger for heavier multi-core work with 0.6% better PassMark. It is also 100.0% better value on MSRP (13.9 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

A6-5345M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2009) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
