① SA Source

Context Before

VR NVL72 CPX (Integrated): Rubin GPU and Rubin CPX within the same compute tray

Evidence

VR NVL72 CPX (Dual Rack): Rubin CPX deployed in a separate rack alongside the VR NVL72 rack

Context After

The standalone/dedicated rack direction materially changes the deployment calculus. A dual-rack approach allows hyperscalers to scale prefill and decode capacity independently, optimize datacenter power envelopes, and reduce system-level failure domains versus tightly coupled trays. More importantly, it formalizes architectural disaggregation between inference prefill (compute-bound) and decode (bandwidth-bound).

Rubin CPX was originally architected as a GDDR7-based accelerator optimized for prefill, based on three key considerations:
