NVIDIA Confirms Some Rosa CPU Details With Its Rigel Core

In a blog post today talking up the single threaded CPU performance of their Vera CPU with Olympus cores, NVIDIA confirmed a few basic details of their next-gen Rosa CPU featuring their "Rigel" core.

While NVIDIA Vera only recently began shipping and in late May we delivered some of the first benchmarks of the NVIDIA Vera CPU, NVIDIA has already begun sharing some brief details around their next-generation Rosa CPU with Rigel core.

NVIDIA shared in a blog post predominantly talking up Vera's single threaded performance benefits:

"NVIDIA’s next-generation Rosa CPU with the Rigel core will continue the company’s CPU roadmap for the agentic AI era. Rigel is NVIDIA’s next-generation Arm v9.2 CPU core, delivering higher per-core performance than Olympus while keeping the same silicon footprint. Key improvements include better instruction delivery, a larger L2 cache and more efficient memory handling."

NVIDIA Rosa will build off Vera's successes as an agentic AI processor while featuring higher per-core performance, larger L2 cache, and more efficient memory handling while sticking to Vera's silicon footprint. That's all for now on the Rosa/Rigel details shared by NVIDIA.

In due time it will be interesting to see how the NVIDIA Rosa CPU can compete with the other server CPU competition in the form of AMD EPYC Venice and Intel Xeon Diamond Rapids.
