    Quick Answers

    So, is Core i7-11800H better than Core i7-9700K?
    It depends on what matters more to you. For gaming, Core i7-9700K is ahead with 6.5% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Core i7-11800H pulls ahead with 37.8% better PassMark. Core i7-11800H also has the bigger cache pool with 100% larger total L3 cache (24 MB vs 12 MB).
    Which one is better for streaming, content creation, and heavy multitasking?
    For streaming, content creation, and heavier multitasking, Core i7-11800H is the better fit. You are getting 37.8% better PassMark, backed by 8 cores and 16 threads. It also carries the larger cache pool with 100% larger total L3 cache (24 MB vs 12 MB).
    Which one is the smarter buy today, not just the cheaper CPU?
    Core i7-11800H is the smarter buy by a wide margin for a fresh build. Core i7-11800H is at an unclear MSRP at unclear MSRP versus $385 MSRP, and it gives you 37.8% better PassMark. Core i7-9700K only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2018 platform. Even with 100.0% better value on paper (37.4 vs 0.0 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA1151.
    Which one is more future-proof for 2026 and beyond?
    Core i7-11800H is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2018), 100% larger total L3 cache (24 MB vs 12 MB), and more multi-core headroom with 8 cores / 16 threads instead of 8/8. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.

    Games Benchmarks

    Paired with RTX 4090

    To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

    Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
