NVIDIA CEO Jensen Huang denied delays for Vera Rubin production, stating "giant amounts of production incoming," reiterating prior announcements of production in January and sampling in February. However, reports from SemiAnalysis indicate delays for the Kyber NVL144 rack-scale solution (copper interconnects) from 2027 to 2028 due to complex PCB midplane manufacturing, and the NVL576 (co-packaged optics) due to "ongoing CPO challenges." An alternative NVL72x2 dual-rack design was reportedly canceled, potentially limiting NVIDIA's scale-up offerings to 72-way systems until 2028.
