About PassMark

PassMark CPU Mark evaluates processor speed through complex mathematical computations. It provides a reliable metric to compare multi-core performance, where higher scores indicate faster processing for multitasking, gaming, and heavy workloads.

Atom E660 vs Sempron 2300+: Pros, Cons & Final Verdict

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

Atom E660

2010

Why buy it

  • ✅Better for gaming: +16.7% higher average FPS across 50 shared CPU benchmark tests.
  • ✅Draws 3W instead of 62W, a 59W reduction.
  • ✅100+% more PCIe lanes (4 vs 0) for storage and expansion-heavy builds.
  • ✅Integrated graphics onboard with Intel GMA 600, while Sempron 2300+ needs a discrete GPU.

Trade-offs

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

Sempron 2300+

2001

Why buy it

    Trade-offs

    • ❌Worse for gaming: lower average FPS than Atom E660 across 50 shared CPU benchmark tests.
    • ❌Lower PassMark (248 vs 275).
    • ❌1966.7% higher power demand at 62W vs 3W.
    • ❌No integrated graphics, while Atom E660 can still boot and troubleshoot without a discrete GPU.

    Quick Answers

    So, is Atom E660 better than Sempron 2300+?
    Yes. Atom E660 is the better all-around CPU here. It gives you a 16.7% average FPS lead across 50 shared CPU game tests in our data, 10.9% better 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, Atom E660 is the better pick. According to our tests, it delivers 16.7% 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, Atom E660 is the stronger fit. You are getting 10.9% better PassMark, backed by 1 cores and 2 threads.
    Which one is the smarter buy today, not just the cheaper CPU?
    Atom E660 still makes the most sense overall. Atom E660 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 16.7% average FPS lead across 50 shared CPU game tests in our data.
    Which one is more future-proof for 2026 and beyond?
    Atom E660 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2001) and more multi-core headroom with 1 cores / 2 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
