1. Overview High Bandwidth Memory (HBM) is a computer memory interface technology for 3D-stacked synchronous dynamic random-access memory (SDRAM), jointly developed by Samsung, AMD, and SK Hynix. In October 2013, HBM was adopted as an industry standard (JESD235) by JEDEC. The technology vertically stacks multiple DRAM dies, using Through-Silicon Vias (TSVs) and microbumps to achieve inter-layer interconnection, and is then tightly coupled with a GPU or accelerator via a silicon interposer, thereby delivering data transfer bandwidth tens of times greater than traditional DDR/GDDR solutions with far smaller volume and lower power consumption. ...

NVIDIA SXM 1. SXM Overview SXM stands for Server PCI Express Module, which is NVIDIA’s proprietary high-bandwidth GPU socket/connector solution designed for mounting data-center-class GPU accelerators directly onto server motherboards. Core Design Philosophy Proprietary: SXM is NVIDIA’s closed proprietary interface standard with undisclosed specifications (requires NDA, Non-Disclosure Agreement), giving NVIDIA complete design freedom High Bandwidth: Direct GPU-to-GPU interconnection via NVLink, with bandwidth far exceeding PCIe High Power: Not limited by the PCIe standard 75W/300W limits; directly powered through the socket up to 700W-1400W+ ...
