    Quick Answers

    So, is Athlon X2 QL-65 better than Core Duo T2500?
    Yes. Athlon X2 QL-65 is the better all-around CPU here. It gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data, 0.6% 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, Athlon X2 QL-65 is the better pick. According to our tests, it delivers 0.1% 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, Athlon X2 QL-65 is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 2 threads.
    Which one is the smarter buy today, not just the cheaper CPU?
    Athlon X2 QL-65 is the better buy right now. Athlon X2 QL-65 comes in at an unclear MSRP at $150 MSRP versus unclear MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (10.9 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
    Which one is more future-proof for 2026 and beyond?
    Athlon X2 QL-65 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2009 vs 2006) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
