    Quick Answers

    So, is Celeron E1400 better than Pentium D 915?
    It depends on what you want from the system. For gaming, Pentium D 915 is ahead with a 0.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron E1400 pulls ahead with 1.4% better PassMark.
    Which one is better for streaming, content creation, and heavy multitasking?
    For streaming, content creation, and heavier multitasking, Celeron E1400 is the stronger fit. You are getting 1.4% better PassMark, backed by 2 cores and 2 threads.
    Which one is the smarter buy today, not just the cheaper CPU?
    Celeron E1400 is the better buy right now. Celeron E1400 comes in $21 cheaper on MSRP at $53 MSRP versus $74 MSRP, and it still gives you 1.4% better PassMark. The compromise is that Pentium D 915 is still the better pure gaming CPU with a 0.1% average FPS lead across 50 shared CPU game tests in our data. It is also 41.6% better value on MSRP (13.5 vs 9.5 PassMark/$), 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 E1400 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2008 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.
