First deep look at the NVIDIA HGX Rubin NVL8 in near-production form. Eight Rubin GPUs at 288GB HBM4 each, NVLink 6 switches bridging the GPU complex, ConnectX-9 at 1.6 TB/s per port, BlueField-4 for KV cache offload, and host CPU choice across Vera, AMD, and Intel. Liquid cooled throughout. #NVIDIA #Rubin #AI #GPU
