AMD Says AI Makes Dual 3D V-Cache More Viable
AMD client product management senior director Travis Kirsch said traditional games process workloads almost entirely on one CCD, so adding 3D V-Cache to both CCDs did not previously provide enough gaming performance to offset the higher price. He said AMD's rationale for the dual-cache Ryzen 9 9950X3D2 is that AI applications offer a more reasonable use case, although the interview did not provide workload benchmarks. The processor launched in the first half covered by the report, with a Chinese price of RMB 6,999. The interview also covered continued AM4 support, AMD's plan to extend AM5 where technical needs allow, and a proposed Ryzen 7 5800X3D anniversary edition for AM4 users.
AMD has provided its economic and application rationale for a dual-cache design that was previously considered insufficiently valuable for gaming. The AI rationale remains the company's explanation rather than a demonstrated workload result.
IT之家 10 月 22 日消息，日本媒体《Mynavi News》当地时间 10 月 20 日放出了对 AMD 客户端产品管理高级总监 Travis Kirsch 的采访，谈到了有关锐龙处理器产品布局、3D V-Cache 技术、内存市场变化以及下一代处理器的规划。
Travis Kirsch 表示，AMD 仍将继续支持 AM4 平台，并计划在技术需求尚未迫使平台升级的情况下，尽可能延长 AM5 平台的生命周期。
2025 年 1 月，AMD 在回答德媒 Hardwareluxx 提问时表示，双 3D V-Cache 缓存设计并不存在技术上的问题，而不推出此类型产品主要是经济方面的考虑。同年，Kirsch 同样是在接受 Mynavi News 采访时表示，“3D V-Cache 是一项昂贵的技术，即使两个芯片都配备也无法提供足够的价值。”
后续，AMD 在今年上半年推出了搭载双 3D V-Cache 缓存的锐龙 9 9950X3D2 处理器，国行售价 6999 元。
对于这一堪称回旋镖的操作，Kirsch 在最新采访中回应称，由于传统游戏基本只能利用单个 CCD，双 CCD 均配备 3D V-Cache 的设计此前难以体现与成本提升相匹配的游戏性能增益。不过，随着 AI 应用的发展，这种设计如今有了更合理的应用空间。IT之家翻译如下：
