What is GPU?
Short for graphics processing unit: a processor with many simple execution units that processes large amounts of data in parallel. Besides graphics, it is widely used for AI training and inference.
Field: CPUs and architecture
GPU in the explanations
Placing the GPU and HBM side by side on a silicon interposer, where fine wiring can be made, connects them over short distances with many wires, achieving the very high memory bandwidth AI computation needs.
In AI GPUs, what is the main reason the GPU chip and HBM ar…Chips are placed around the GPU on the board with short traces.
Which is a characteristic of GDDR, used as graphics memory …AI packages need interposers several times that size to hold a GPU and many HBM stacks.
