Quick Answers

So, is Turion II Neo K625 better than Core 2 Duo E6420?

It depends on what you want from the system. For gaming, Core 2 Duo E6420 is ahead with 42% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Turion II Neo K625 pulls ahead with 0.5% better PassMark.

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

For streaming, content creation, and heavier multitasking, Turion II Neo K625 is the stronger fit. You are getting 0.5% better PassMark, backed by 2 cores and 2 threads.

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

Turion II Neo K625 is still the much better call for a fresh build. Turion II Neo K625 comes in at an unclear MSRP at unclear MSRP versus $183 MSRP, and it still gives you 0.5% better PassMark. Core 2 Duo E6420 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2007 platform. Even with 100.0% better value on paper (6.7 vs 0.0 PassMark/$), 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?

Turion II Neo K625 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2007) 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.
