NVIDIA发布Vera CPU基准测试报告。Vera采用Armv9.2架构，在Phoronix测试中，其整体性能比128核x86 CPU高1.5倍，比前代Grace CPU提升1.6倍（几何平均）。其每核心内存带宽是传统x86 CPU的4倍以上，使用LPDDR5X实现1.2TB/s带宽，内存功耗低于30W。该报告旨在表明NVIDIA的Arm架构CPU性能已超越Intel和AMD的x86服务器CPU，并强调在智能体AI场景下，因涉及工具调用、文件读写、代码生成等复杂任务，CPU侧工作负载变得更重。
NVIDIA published a report on Vera CPU benchmarks, done by Phoronix.
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.
