NVIDIA GB200 Grace Blackwell Superchip

Pairs 1 Grace CPU with 2 Blackwell GPUs over 900 GB/s NVLink-C2C; vramGb reflects HBM3e per Blackwell GPU (matches standalone B200 top-bin figure). Typically deployed rack-scale as GB200 NVL72 (36 Grace CPUs + 72 Blackwell GPUs acting as one NVLink domain: up to 13.4 TB HBM3e, 576 TB/s aggregate bandwidth, FP8/FP6 720 PFLOPS and FP4 1,440 PFLOPS for the full 72-GPU rack). Per-GPU fp16Tflops/fp8Tflops are not separately broken out on the pages checked; left unset rather than inferred from rack-level figures.
