Quick Answers

So, is Core 2 Duo E8700 better than Core i3-5020U?

It depends on what you want from the system. For gaming, Core 2 Duo E8700 is ahead with a 0.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-5020U 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, Core i3-5020U is the stronger fit. You are getting 0.9% better PassMark, backed by 2 cores and 4 threads.

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

Core 2 Duo E8700 is the better buy right now. Core 2 Duo E8700 comes in at an unclear MSRP at $256 MSRP versus unclear MSRP, and it still gives you a 0.6% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i3-5020U is still stronger for heavier multi-core work with 0.9% better PassMark. It is also 100.0% better value on MSRP (8.6 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i3-5020U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2009) and more multi-core headroom with 2 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.
