Quick Answers

So, is Core 2 Quad Q9300 better than Core i3-5005U?

It depends on what you want from the system. For gaming, Core 2 Quad Q9300 is ahead with a 1.6% 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% 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% better PassMark, backed by 2 cores and 4 threads.

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

Core 2 Quad Q9300 is the better buy right now. Core 2 Quad Q9300 comes in at an unclear MSRP at $266 MSRP versus unclear MSRP, and it still gives you a 1.6% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i3-5005U is still stronger for heavier multi-core work with 0% better PassMark. It is also 100.0% better value on MSRP (7.6 vs 0.0 PassMark/$), 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 i3-5005U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2008) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
