Quick Answers

So, is Core i3-5005U better than Core 2 Duo T7600?

It depends on what you want from the system. For gaming, Core 2 Duo T7600 is ahead with a 1.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-5005U pulls ahead with 0.4% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i3-5005U is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 4 threads.

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

Core i3-5005U still makes the most sense overall. Core i3-5005U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.4% better PassMark.

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

Core i3-5005U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2006) 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.
