NVIDIA GTC 2026 Keynote March 16: Rubin GPU with 288GB HBM4, 5x Blackwell Throughput Expected
Jensen Huang's two-hour keynote kicks off March 16 in San Jose. Rubin-generation GPUs are expected to be the centerpiece, featuring up to 288GB HBM4 memory, 22TB/s bandwidth, and 35-50 petaFLOPS of dense NVFP4 performance — approximately 5x the floating-point throughput of current Blackwell parts. NVIDIA is also expected to detail OpenClaw, its agentic AI platform for always-running local assistants, and new cooling targets likely exceeding one megawatt per rack.
