    Quick Answers

    So, is Ryzen 7 7800X3D better than Core Ultra 5 115U?
    Yes. Ryzen 7 7800X3D is the better all-around CPU here. It gives you a 90.0% average FPS lead across 34 shared CPU game tests in our data, 197.7% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.
    Which one is better for gaming?
    If gaming is the priority, Ryzen 7 7800X3D is the better pick. According to our tests, it delivers 90.0% more average FPS across 34 shared CPU game tests. It also has a clear cache advantage at 96 MB versus 10 MB.
    Which one is better for streaming, content creation, and heavy multitasking?
    For streaming, content creation, and heavier multitasking, Ryzen 7 7800X3D is the stronger fit. You are getting 197.7% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 860% larger total L3 cache (96 MB vs 10 MB).
    Which one is the smarter buy today, not just the cheaper CPU?
    Ryzen 7 7800X3D is the better buy right now. Ryzen 7 7800X3D comes in at an unclear MSRP at $449 MSRP versus unclear MSRP, and it still gives you a 90.0% average FPS lead across 34 shared CPU game tests in our data. It is also 100.0% better value on MSRP (76.4 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
    Which one is more future-proof for 2026 and beyond?
    Ryzen 7 7800X3D makes more sense long term for 2026 and beyond. You are getting 3D V-Cache and a much larger 96 MB L3 cache instead of 10 MB and more multi-core headroom with 8 cores / 16 threads instead of 8/10. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
