Quick Answers

So, is Phenom II X2 N640 better than Core i3-380UM?

It depends on what you want from the system. For gaming, Phenom II X2 N640 is ahead with a 2.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-380UM pulls ahead with 6.9% better Geekbench multi-core.

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

For streaming, content creation, and heavier multitasking, Core i3-380UM is the stronger fit. You are getting 6.9% better Geekbench multi-core, backed by 2 cores and 4 threads.

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

Phenom II X2 N640 is the better buy right now. Phenom II X2 N640 comes in at an unclear MSRP at $100 MSRP versus unclear MSRP, and it still gives you a 2.4% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i3-380UM is still stronger for heavier multi-core work with 6.9% better Geekbench multi-core. It is also 100.0% better value on MSRP (15.1 vs 0.0 PassMark/$), 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 i3-380UM makes more sense long term for 2026 and beyond. You are getting 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.
