NVIDIA GB200 NVL72 GPU 186GB

This is a single Blackwell GPU as deployed inside a GB200 NVL72 rack, which is the unit cloud providers actually rent and quote. It is the same silicon as the HGX B200 but a different bin: NVIDIA rates the liquid-cooled rack part about 11 percent higher on every tensor and shader row, and gives it 186 GB of HBM3e against the air-cooled board's 180 GB. Dense NVFP4 is 10 PFLOPS here against the HGX part's 9. NVLink 5 carries 1.8 TB/s per GPU, which is what makes a 72-GPU coherent domain practical in the first place. Two of these plus one Grace CPU make up the GB200 Grace Blackwell Superchip, so that row's figures are pair totals and sit at roughly double the ones here. If you are comparing rental prices, this is the row to compare against; if you are costing rack hardware, the superchip row is the building block.
