Quick Answers

So, is Atom Z3740 better than Phenom II X6 1065T?

It depends on what you want from the system. For gaming, Atom Z3740 is ahead with a 4.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Phenom II X6 1065T pulls ahead with 0.9% better PassMark.

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

For streaming, content creation, and heavier multitasking, Phenom II X6 1065T is the stronger fit. You are getting 0.9% better PassMark, backed by 6 cores and 6 threads.

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

Atom Z3740 is still the much better call for a fresh build. Atom Z3740 comes in at an unclear MSRP at unclear MSRP versus $426 MSRP, and it still gives you a 4.9% average FPS lead across 50 shared CPU game tests in our data. Phenom II X6 1065T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (8.0 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on AM3.

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

Atom Z3740 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2010). That makes it the safer long-term bet.
