Quick Answers

So, is Core 2 Duo E4600 better than Atom x5-Z8500?

It depends on what you want from the system. For gaming, Core 2 Duo E4600 is ahead with a 0.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Atom x5-Z8500 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, Atom x5-Z8500 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?

Core 2 Duo E4600 is the better buy right now. Core 2 Duo E4600 comes in at an unclear MSRP at $133 MSRP versus unclear MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Atom x5-Z8500 is still stronger for heavier multi-core work with 0.6% better PassMark. It is also 100.0% better value on MSRP (9.3 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Atom x5-Z8500 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2007) 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.
