    Quick Answers

    So, is EPYC 4545P better than Ryzen 9 7940HX?
    Not in a simple one-size-fits-all way. EPYC 4545P makes more sense for workstation-style multi-core throughput, while Ryzen 9 7940HX is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.
    Which one is better for gaming?
    If gaming is the priority, EPYC 4545P is the better pick here. According to our tests, it delivers 1.1% more average FPS across 4 shared CPU game tests.
    Which one is better for streaming, content creation, and heavy multitasking?
    For streaming, content creation, and heavier multitasking, EPYC 4545P is the better fit. You are getting 1.2% better PassMark, backed by 16 cores and 32 threads.
    Which one is the smarter buy today, not just the cheaper CPU?
    EPYC 4545P is the smarter buy today. EPYC 4545P is at an unclear MSRP at $549 MSRP versus unclear MSRP, and it gives you a 1.1% average FPS lead across 4 shared CPU game tests in our data. It is also 100.0% better value on MSRP (98.8 vs 0.0 PassMark/$), 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?
    EPYC 4545P is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2024) and more multi-core headroom with 16 cores / 32 threads instead of 16/32. 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.
