NVIDIA's next-generation AI GPU, the B100 "Blackwell," is now in the hands of the company's biggest ecosystem partners and customers for evaluation, and one of them is Dell. Jeff Clarke, the OEM giant's chief operating officer, speaking to industry analysts in an investor teleconference, said that he is excited about the upcoming B100 and B200 chips from NVIDIA. B100 is codename for the AI GPU NVIDIA designs for PCIe add-on card and the SXM socket, meant for systems powered by x86 CPUs such as the AMD EPYC or Intel Xeon Scalable. The B200 is its variant meant for machines powered by NVIDIA's in-house Arm-based processors, such as the successor to its Grace CPU, and its combination with an AI GPU, called Grace Hopper (GH200).

Perhaps the most interesting remark by Clarke about the B100 is that he doesn't think it needs liquid cooling, and can make do with high-airflow cooling like the H100. "We're excited about what happens at the B100 and the B200, and we think that's where there's actually another opportunity to distinguish engineering confidence. Our characterization in the thermal side, you really don't need to direct-liquid cooling to get to the energy density of 1000 W per GPU. That happens next year with the B200," he said. NVIDIA is planning a 2024 debut for "Blackwell" in the AI GPU space with the B100, with B200 slated for 2025, possibly alongside a new CPU.
