    • 1116.7% higher power demand at 73W vs 6W.

    Pentium Silver N5000

    2017

    Why buy it

    • +0.1% higher PassMark.
    • Draws 6W instead of 73W, a 67W reduction.

    Trade-offs

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

    Quick Answers

    So, is Pentium Silver N5000 better than Core i5-660?
    It depends on what you want from the system. For gaming, Core i5-660 is ahead with a 0.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium Silver N5000 pulls ahead with 0.1% better PassMark.
    Which one is better for streaming, content creation, and heavy multitasking?
    For streaming, content creation, and heavier multitasking, Pentium Silver N5000 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 4 threads.
    Which one is the smarter buy today, not just the cheaper CPU?
    Pentium Silver N5000 is still the much better call for a fresh build. Pentium Silver N5000 comes in at an unclear MSRP at unclear MSRP versus $196 MSRP, and it still gives you 0.1% better PassMark. Core i5-660 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (12.4 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1156.
    Which one is more future-proof for 2026 and beyond?
    Pentium Silver N5000 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2010) and more multi-core headroom with 4 cores / 4 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
