    Quick Answers

    So, is Core i5-10400F better than Core i5-2450P?
    Yes. Core i5-10400F is the better all-around CPU here. It gives you a 114.9% average FPS lead across 50 shared CPU game tests in our data, 212.6% better Geekbench multi-core, 204.9% higher 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 i5-10400F is the better pick. According to our tests, it delivers 114.9% 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 i5-10400F is the stronger fit. You are getting 212.6% better Geekbench multi-core, backed by 6 cores and 12 threads. It also has the larger cache pool with 100% larger total L3 cache (12 MB vs 6 MB).
    Which one is the smarter buy today, not just the cheaper CPU?
    Core i5-10400F is the better buy right now. Core i5-10400F comes in $17 cheaper on MSRP at $160 MSRP versus $177 MSRP, and it still gives you a 114.9% average FPS lead across 50 shared CPU game tests in our data. It is also 237.3% better value on MSRP (81.4 vs 24.1 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
    Which one is more future-proof for 2026 and beyond?
