Quick Answers

So, is A8-4555M better than Athlon X2 340?

It depends on what you want from the system. For gaming, Athlon X2 340 is ahead with a 2.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, A8-4555M 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, A8-4555M is the stronger fit. You are getting 0.6% better PassMark, backed by 4 cores and 4 threads.

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

A8-4555M is still the much better call for a fresh build. A8-4555M comes in at an unclear MSRP at unclear MSRP versus $30 MSRP, and it still gives you 0.6% better PassMark. Athlon X2 340 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 100.0% better value on paper (44.4 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on FM2.

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

A8-4555M makes more sense long term for 2026 and beyond. You are getting 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.
