Quick Answers

So, is Core i7-720QM better than Core 2 Duo T5500?

It depends on what you want from the system. For gaming, Core i7-720QM is ahead with a 1.9% average FPS lead across 29 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 2 Duo T5500 pulls ahead with 0.1% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core 2 Duo T5500 is the stronger fit. You are getting 0.1% better PassMark, backed by 2 cores and 2 threads.

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

Core i7-720QM is the better buy right now. Core i7-720QM comes in at an unclear MSRP at $364 MSRP versus unclear MSRP, and it still gives you a 1.9% average FPS lead across 29 shared CPU game tests in our data. The compromise is that Core 2 Duo T5500 is still stronger for heavier multi-core work with 0.1% better PassMark. It is also 100.0% better value on MSRP (4.6 vs 0.0 PassMark/$), 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 i7-720QM makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2009 vs 2007). That makes it the safer long-term bet.
