    Which one is the smarter buy today, not just the cheaper CPU?
    Core i7-9700K is the smarter buy today. Core i7-9700K is at an unclear MSRP at $385 MSRP versus unclear MSRP, and it gives you a 167.8% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (37.4 vs 0.0 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.
    Which one is more future-proof for 2026 and beyond?
    Core i7-9700K is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2010), 100% larger total L3 cache (12 MB vs 6 MB), and more multi-core headroom with 8 cores / 8 threads instead of 6/6. 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.
