NVIDIA 用 Arm 架构正面挑战 Intel/AMD 服务器 CPU，性能更强且功耗更低，做 AI 推理和智能体系统的团队值得关注——CPU 端负载正在变重，Vera 可能是更优选择。
NVIDIA 发布了由 Phoronix 完成的 Vera CPU 基准测试报告。报告显示，Vera 相比当前 128 核 x86 CPU 整体性能领先 1.5 倍，相比前代 Grace CPU 几何平均性能提升 1.6 倍。Vera 采用 Armv9.2 架构，每核内存带宽是传统 x86 的 4 倍以上，LPDDR5X 带宽达 1.2TB/s，功耗仅 30W，而典型 DDR5 服务器功耗超 100W。对于智能体 AI 场景，CPU 端任务（如工具调用、文件读写、浏览器操作）日益繁重，Vera 的高效计算能力将显著提升这类工作负载的表现。

Compares Vera directly against a current 128-core x86 CPU and claims a 1.5x overall performance advantage
Compared with the prior-generation NVIDIA Grace CPU, Vera delivered a 1.6x geometric mean increase in Phoronix’s testing.
Vera delivered over 4x the memory bandwidth per core compared with traditional x86 CPUs.
Vera delivers 1.2TB/s bandwidth using LPDDR5X, while keeping memory power under 30W, compared with more than 100W for many DDR5 server setups.
---- To note, Vera uses Armv9.2, not x86, so NVIDIA is basically saying that their Arm-based CPU can beat the usual Intel and AMD server CPUs.
For agentic AI, this CPU-side work becomes much heavier because the AI is not only generating text, but also calling tools, reading files, writing code, using browsers, running sandboxes, and managing workflows.
