Quick Answers

So, is Core i7-3520M better than Core 2 Duo SP9600?

Yes. Core i7-3520M is the better all-around CPU here. It gives you a 5.0% average FPS lead across 50 shared CPU game tests in our data, 0.2% 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 i7-3520M is the better pick. According to our tests, it delivers 5.0% 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 i7-3520M is the stronger fit. You are getting 0.2% better PassMark, backed by 2 cores and 4 threads.

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

Core i7-3520M is the easy recommendation for a fresh desktop build. Core i7-3520M comes in 9.5% more expensive on MSRP at $346 MSRP versus $316 MSRP, and it still gives you a 5.0% average FPS lead across 50 shared CPU game tests in our data. Core 2 Duo SP9600 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 5.0% in the shared gaming data.

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

Core i7-3520M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 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.
