Radeon Pro Vega graphics.
The 15-inch MacBook Pro offers Radeon Pro Vega GPU options — the first discrete mobile Vega GPUs in a notebook. Vega, the same graphics architecture found in iMac Pro, delivers an enhanced compute engine and utilises High Bandwidth Memory (HBM2). HBM2 doubles the memory bandwidth to the GPU while doing so at considerably lower power, so more of the graphics power budget can be used by the GPU itself. The result is significantly faster graphics performance — up to 60 per cent faster than the Radeon Pro 560X13 — for tackling demanding video, 3D, rendering and compute workloads.
