    Quick Answers

    So, is Core i7-4550U better than Turion II Ultra M660?
    Yes. Core i7-4550U is the better all-around CPU here. It gives you a 0.4% average FPS lead across 50 shared CPU game tests in our data, 1.3% 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 i7-4550U is the better pick. According to our tests, it delivers 0.4% 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 i7-4550U is the stronger fit. You are getting 1.3% better PassMark, backed by 2 cores and 4 threads.
    Which one is the smarter buy today, not just the cheaper CPU?
    Core i7-4550U still makes the most sense overall. Core i7-4550U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 0.4% average FPS lead across 50 shared CPU game tests in our data.
    Which one is more future-proof for 2026 and beyond?
    Core i7-4550U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 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.
