The B100 is a professional graphics card by NVIDIA, launched in 2024. Built on the 5 nm process, and based on the GB100 graphics processor, the card does not support DirectX. Since B100 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. B100 combines two graphics processors to increase performance. It features 16896 shading units, 528 texture mapping units, and 24 ROPs, per GPU. Also included are 528 tensor cores which help improve the speed of machine learning applications. NVIDIA has paired 192 GB HBM3e memory with the B100, which are connected using a 4096-bit memory interface per GPU (each GPU manages 98,304 MB). The GPU is operating at a frequency of 1665 MHz, which can be boosted up to 1837 MHz, memory is running at 2000 MHz.
Being a sxm module card, its power draw is rated at 1000 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. B100 is connected to the rest of the system using a PCI-Express 5.0 x16 interface.
