Quick Answers

So, is Core i7-740QM better than Core 2 Duo T5550?
Yes. Core i7-740QM is the better all-around CPU here. It gives you a 3.7% average FPS lead across 50 shared CPU game tests in our data, 0.9% 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 i7-740QM is the better pick. According to our tests, it delivers 3.7% 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 i7-740QM is the stronger fit. You are getting 0.9% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 200% larger total L3 cache (6 MB vs 2 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-740QM is the better buy right now. Core i7-740QM comes in at an unclear MSRP at $378 MSRP versus unclear MSRP, and it still gives you a 3.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (4.9 vs 0.0 PassMark/$), 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 i7-740QM makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2008), 200% larger total L3 cache (6 MB vs 2 MB), and more multi-core headroom with 4 cores / 8 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
