NVIDIA B100: specs and benchmarks
Contents
Summary
NVIDIA started B100 sales on November 2024. This is a Blackwell architecture desktop card based on 5 nm manufacturing process and primarily aimed at designers. 96 GB of HBM3e memory clocked at 2 GHz are supplied, and together with 4096 Bit memory interface this creates a bandwidth of 4.1 TB/s.
Compatibility-wise, this is a sxm module graphics card attached via PCIe 5.0 x16 interface. No additional power connector is required, and power consumption is at 1000 Watt.
