8-high HBM3E stack with 24 GB capacity and 9.2 Gbps per pin, proven in volume on shipping AI accelerator platforms.
Capacities
Overview
What this part is for
The 8-high HBM3E stack was the first extended-HBM3 product to reach volume production, supplying 24 GB per stack at 9.2 Gbps per pin — roughly 1.18 TB/s of bandwidth. It ships in high volume on current AI accelerator platforms across training and inference roles.
MR-MUF packaging and proven TSV yield give the 8-high stack a mature supply profile relative to newer 12-high parts, making it the volume anchor of HBM3E procurement. Thermal behavior and power draw per stack are correspondingly lower than 12-high configurations.
