Core i7-2860QM vs Pentium Gold G6605: Pros, Cons & Final Verdict

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

Core i7-2860QM

2011

Why buy it

  • Better for gaming: +8.8% higher average FPS across 50 shared CPU benchmark tests.
  • +100% larger total L3 cache (8 MB vs 4 MB).
  • Draws 45W instead of 58W, a 13W reduction.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with Intel HD Graphics 3000, while Pentium Gold G6605 needs a discrete GPU.

Trade-offs

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

Pentium Gold G6605

2021

Why buy it

    Trade-offs

    • Worse for gaming: lower average FPS than Core i7-2860QM across 50 shared CPU benchmark tests.
    • Lower PassMark (4,488 vs 4,597).
    • Smaller total L3 cache (4 MB vs 8 MB).
    • 28.9% higher power demand at 58W vs 45W.

    Quick Answers

    So, is Core i7-2860QM better than Pentium Gold G6605?
    Yes. Core i7-2860QM is the better all-around CPU here. It gives you a 8.8% average FPS lead across 50 shared CPU game tests in our data and 2.4% better PassMark, which is enough to make it the stronger overall pick.
    Which one is better for gaming?
    If gaming is the priority, Core i7-2860QM is the better pick. According to our tests, it delivers 8.8% 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, Core i7-2860QM is the stronger fit. You are getting 2.4% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 100% larger total L3 cache (8 MB vs 4 MB).
    Which one is the smarter buy today, not just the cheaper CPU?
    Core i7-2860QM still makes the most sense overall. Core i7-2860QM comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 8.8% average FPS lead across 50 shared CPU game tests in our data. That said, if you already own a compatible LGA1200 + DDR4 setup, Pentium Gold G6605 can still make sense as a platform-matched option because it avoids a motherboard and RAM swap.
    Which one is more future-proof for 2026 and beyond?
    Pentium Gold G6605 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2011). That makes it the safer long-term bet.
