Quick Answers

So, is Core m7-6Y75 better than Core 2 Duo T6600?

Yes. Core m7-6Y75 is the better all-around CPU here. It gives you a 2.2% average FPS lead across 50 shared CPU game tests in our data, 0.3% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core m7-6Y75 is the better pick. According to our tests, it delivers 2.2% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Core m7-6Y75 is the stronger fit. You are getting 0.3% better PassMark, backed by 2 cores and 4 threads. It also has the larger cache pool with 100% larger total L3 cache (4 MB vs 2 MB).

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

Core m7-6Y75 is the better buy right now. Core m7-6Y75 comes in at an unclear MSRP at $393 MSRP versus unclear MSRP, and it still gives you a 2.2% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (6.0 vs 0.0 PassMark/$), 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 m7-6Y75 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2009), 100% larger total L3 cache (4 MB vs 2 MB), 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.
