NVIDIA Cuts HBM4 Speed and NVLink Bandwidth Targets for "Vera Rubin"
NVIDIA has officially revised the technical specifications for its upcoming Vera Rubin product line, resulting in lower performance targets for both memory and interconnect fabric. The company reduced the HBM4 memory speed from 11.7 Gbps per pin to 9.6 Gbps per pin, which lowers the total memory bandwidth for the NVL72 rack-scale solution from 1,580 TB/s to 1,400 TB/s.
