Pentium D 940 vs Sempron 2650: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Pentium D 940

2006

Why buy it

    Trade-offs

    • Lower PassMark (875 vs 892).
    • Launch MSRP is still $132 MSRP, while Sempron 2650 mostly shows up through inconsistent older-market listings.
    • 420% higher power demand at 130W vs 25W.

    Sempron 2650

    2014

    Why buy it

    • +1.9% higher PassMark.
    • Draws 25W instead of 130W, a 105W reduction.

    Trade-offs

    • Fewer obvious downsides in this matchup outside of normal market pricing swings.

    Quick Answers

    So, is Sempron 2650 better than Pentium D 940?
    It depends on what you want from the system. For gaming, Pentium D 940 is ahead with 120.7% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Sempron 2650 pulls ahead with 1.9% better PassMark.
    Which one is better for streaming, content creation, and heavy multitasking?
    For streaming, content creation, and heavier multitasking, Sempron 2650 is the stronger fit. You are getting 1.9% better PassMark, backed by 2 cores and 2 threads.
    Which one is the smarter buy today, not just the cheaper CPU?
    Sempron 2650 is still the much better call for a fresh build. Sempron 2650 comes in at an unclear MSRP at unclear MSRP versus $132 MSRP, and it still gives you 1.9% better PassMark. Pentium D 940 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2006 platform. Even with 100.0% better value on paper (6.6 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.
    Which one is more future-proof for 2026 and beyond?
    Sempron 2650 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 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.
