Quick Answers

So, is A9-9420e better than Core 2 Duo E8435?

It depends on what you want from the system. For gaming, A9-9420e is ahead with 3471.4% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Core 2 Duo E8435 pulls ahead with 0.3% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core 2 Duo E8435 is the stronger fit. You are getting 0.3% better PassMark, backed by 2 cores and 2 threads.

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

A9-9420e is still the much better call for a fresh build. A9-9420e comes in at an unclear MSRP at unclear MSRP versus $150 MSRP, and it still gives you 3471.4% higher max boost clock. Core 2 Duo E8435 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 100.0% better value on paper (7.4 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on P.

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

A9-9420e makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2009). That makes it the safer long-term bet.
