Phoronix发布了NVIDIA Vera CPU的首份公开基准测试。这款ARM架构数据中心处理器拥有88个Olympus核心，专为智能体AI（Agentic AI）所需的代码执行、工具调用与数据管道设计。测试数据显示，Vera编译Linux内核耗时20秒，为测试最快。其整体性能较Intel Xeon 6980P提升约1.55倍，较AMD EPYC 9575F平均领先约10%。内存方面，Vera采用LPDDR5X，提供高达1.2 TB/s的带宽，每核内存带宽是传统x86 CPU的4倍以上，且在STREAM TRIAD测试中达到了90%的峰值带宽利用率。与上一代Grace CPU相比，Vera性能平均提升1.63倍。该处理器预计于2026年H2出货给合作伙伴。

Phoronix just published one of the first public benchmarks of NVIDIA's Vera CPU. I went through the full 11-page review this morning and the results are genuinely impressive.

For those who don't follow server hardware： Vera is NVIDIA's new ARM-based data center processor with 88 custom-designed Olympus cores. The idea is straightforward. Agentic AI doesn't just need powerful GPUs. It needs CPUs that can keep up with code execution， tool calls， orchestration and data pipelines， all running concurrently at scale.

The numbers are strong. Vera compiled a default Linux kernel in 20 seconds， the fastest result in Phoronix's tested field. Across all tested workloads， it delivered about 1.55x the performance of Intel's Xeon 6980P. Against AMD's EPYC 9575F， it came out about 10% ahead on a geometric mean basis.

The memory story might be even more interesting. Vera uses LPDDR5X with up to 1.2 TB/s of bandwidth and delivers more than 4x the memory bandwidth per core compared to traditional x86 server CPUs. In the STREAM TRIAD benchmark， it sustained 90% of its rated peak bandwidth， the highest ratio Phoronix has measured on any CPU. If you're running agentic workloads with dozens of parallel processes and concurrent data queries， that kind of consistent memory performance matters more than core count on a spec sheet.

Compared to NVIDIA's own Grace CPU， Vera is 1.63x faster in the geometric mean. That is an unusually large generation-over-generation jump for a CPU.

Michael Larabel， who founded Phoronix and has been benchmarking Linux hardware for over two decades， said he's never seen any ARM processor compete with Intel and AMD at this level.

I was at GTC in March when Jensen announced Vera. The thesis that agentic AI creates entirely new CPU demand made sense to me then. These benchmarks are the first real numbers behind that thesis. And they deliver.
