    Quick Answers

    So, is Core i7-10810U better than Core i7-8709G?
    Yes. Core i7-10810U is the better all-around CPU here. It gives you a 19.6% average FPS lead across 50 shared CPU game tests in our data, 0.7% 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, Core i7-10810U is the better pick. According to our tests, it delivers 19.6% 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 i7-10810U is the stronger fit. You are getting 0.7% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).
    Which one is the smarter buy today, not just the cheaper CPU?
    Core i7-10810U is the easy recommendation for a fresh desktop build. Core i7-10810U comes in at an unclear MSRP at unclear MSRP versus $338 MSRP, and it still gives you a 19.6% average FPS lead across 50 shared CPU game tests in our data. Core i7-8709G only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 19.6% in the shared gaming data.
    Which one is more future-proof for 2026 and beyond?
    Core i7-10810U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2018), 50% larger total L3 cache (12 MB vs 8 MB), and more multi-core headroom with 6 cores / 12 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
