NVIDIA Adds Rosa CPU, Rigel Core to its Roadmap - Data Center Richness | Substack

NVIDIA has unveiled details of its next-generation data center CPU roadmap, including the Vera CPU currently in use and the upcoming Rosa CPU, built around a new Rigel core. This development underscor... Read original →

NVIDIA’s aggressive CPU roadmap signals a structural response to AI compute bottlenecks. The Rigel core isn’t just about performance—it forces a rewrite of the data center software stack, compelling compiler and scheduler developers to optimize for tight CPU-GPU co-processing. Geopolitically, reliance on TSMC’s CoWoS packaging in Taiwan, China creates acute supply chain vulnerability; any disruption could delay Rosa’s ramp. Facing AMD’s MI300X+EPYC synergy and Intel’s Gaudi3+Sierra Forest push, NVIDIA is betting on full-stack control—but risks alienating OEMs wary of over-dependence. Within 18 months, AI inference will converge on a ‘GPU-primary, CPU-accelerator’ model, redefining CPUs as specialized pipeline units rather than general-purpose engines, fundamentally reshaping x86 vs. Arm dynamics in data centers.
