    Quick Answers

    So, is Xeon Platinum 8481C better than Core Ultra 5 115U?
    Not really, because they are built for different jobs. Xeon Platinum 8481C makes more sense for workstation-style multi-core throughput, while Core Ultra 5 115U is the more practical desktop choice for gaming, platform cost, and everyday use.
    Which one is better for gaming?
    If gaming is the priority, Xeon Platinum 8481C is the better pick. According to our tests, it delivers 14.5% more average FPS across 50 shared CPU game tests. It also has a clear cache advantage at 105 MB versus 10 MB.
    Which one is better for streaming, content creation, and heavy multitasking?
    For streaming, content creation, and heavier multitasking, Xeon Platinum 8481C is the stronger fit. You are getting 1.4% better PassMark, backed by 56 cores and 112 threads. It also has the larger cache pool with 950% larger total L3 cache (105 MB vs 10 MB).
    Which one is the smarter buy today, not just the cheaper CPU?
    Xeon Platinum 8481C still makes the most sense overall. Xeon Platinum 8481C comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 14.5% average FPS lead across 50 shared CPU game tests in our data.
    Which one is more future-proof for 2026 and beyond?
    Xeon Platinum 8481C makes more sense long term for 2026 and beyond. You are getting 3D V-Cache and a much larger 105 MB L3 cache instead of 10 MB and more multi-core headroom with 56 cores / 112 threads instead of 8/10. That extra cache should keep paying off in CPU-limited games and high-refresh builds.
