Quick Answers

So, is A6-3420M better than Core 2 Duo E8500?

It depends on what you want from the system. For gaming, Core 2 Duo E8500 is ahead with a 2.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, A6-3420M pulls ahead with 1% better PassMark.

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

For streaming, content creation, and heavier multitasking, A6-3420M is the stronger fit. You are getting 1% better PassMark, backed by 4 cores and 4 threads.

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

A6-3420M is still the much better call for a fresh build. A6-3420M comes in at an unclear MSRP at unclear MSRP versus $26 MSRP, and it still gives you 1% better PassMark. Core 2 Duo E8500 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 100.0% better value on paper (49.9 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.

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

A6-3420M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2008) 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.
