    Which one is the smarter buy today, not just the cheaper CPU?
    Core Ultra 7 255HX is still the faster CPU overall, but Core Ultra 7 265 makes more sense if price matters more than absolute performance. Core Ultra 7 255HX is at an unclear MSRP at unclear MSRP versus $384 MSRP, and it gives you 0.2% better PassMark. The trade-off is that Core Ultra 7 265 is still the better pure gaming CPU with a 0.3% average FPS lead across 50 shared CPU game tests in our data. Core Ultra 7 265 is also 100.0% better value on MSRP (129.3 vs 0.0 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.
    Which one is more future-proof for 2026 and beyond?
    Core Ultra 7 255HX is the more future-proof choice for 2026 and beyond. You are getting more multi-core headroom with 20 cores / 20 threads instead of 20/20. 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.
