    Quick Answers

    So, is Celeron G540 better than Athlon 64 X2 4000+?
    Yes. Celeron G540 is the better all-around CPU here. It gives you a 1.4% average FPS lead across 47 shared CPU game tests in our data, 72.4% better Geekbench multi-core, 0.6% 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, Celeron G540 is the better pick. According to our tests, it delivers 1.4% more average FPS across 47 shared CPU game tests.
    Which one is better for streaming, content creation, and heavy multitasking?
    For streaming, content creation, and heavier multitasking, Celeron G540 is the stronger fit. You are getting 72.4% better Geekbench multi-core, backed by 2 cores and 2 threads.
    Which one is the smarter buy today, not just the cheaper CPU?
    Celeron G540 is the better buy right now. Celeron G540 comes in $286 cheaper on MSRP at $42 MSRP versus $328 MSRP, and it still gives you a 1.4% average FPS lead across 47 shared CPU game tests in our data. It is also 685.6% better value on MSRP (28.1 vs 3.6 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
    Which one is more future-proof for 2026 and beyond?
    Celeron G540 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2006) and more multi-core headroom with 2 cores / 2 threads instead of 2/2.
