AMD "Vega 20" Optical-Shrunk GPU Surfaces in Linux Patches
AMD "Vega 20" is rumored to be an optical shrink of the current "Vega 10" GPU die to a newer process, either 12 nm, or 10 nm, or perhaps even 7 nm. Six new device IDs that point to "Vega 20" based products, surfaced on AMD's GPU drivers source code, with its latest commit made as recently as on 28th March. AMD "Vega 10" is a multi-chip module of a 14 nm GPU die, and two "10 nm-class" HBM2 memory stacks, sitting on a silicon interposer that facilitates high-density wiring between the three. In an effort to increase clock speeds, efficiency, or both, AMD could optically shrink the GPU die to a smaller silicon fabrication process, and carve out a new product line based on the resulting chip.
