Nvidia reveals Blackwell B200 GPU, the ‘world’s most powerful chip’ for AI

Twenty petaflops of AI performance, says Nvidia.

Nvidia’s must-have H100 AI chip made it a multitrillion-dollar company, one that may be worth more than Alphabet and Amazon, and competitors have been fighting to catch up. Nvidia told journalists one of the key improvements is a second-gen transformer engine that doubles the compute, bandwidth, and model size by using four bits for each neuron instead of eight (thus, the 20 petaflops of FP4 I mentioned earlier). Nvidia is counting on companies buying large quantities of these GPUs, of course, and is packaging them in larger supercomputer-ready designs, like the GB200 NVL72, which plugs 36 CPUs and 72 GPUs into a single liquid-cooled rack for a total of 720 petaflops of AI training performance or 1,440 petaflops (aka 1.4 exaflops) of inference.
