# B200 (InfiniBand)

> Specifications, pricing, and availability for the B200 (InfiniBand) GPU instance

Powered by eight NVIDIA B200 Blackwell GPUs, each with 180 GB of HBM3e memory, these instances deliver outstanding performance for enterprise AI workloads, including training and real-time inference. They offer more than twice the performance per GPU compared to previous-generation NVIDIA Hopper GPUs. The GPUs are interconnected using NVIDIA NVLink and NVLink Switch to enable fast data transfer. For networking, B200 instances feature an NVIDIA BlueField-3 DPU and eight NVIDIA ConnectX-7 InfiniBand host channel adapters (HCAs), supporting high throughput and lossless scaling. A 400G NDR non-blocking NVIDIA Quantum-2 InfiniBand fabric ensures seamless, high-speed connectivity.
