I am only going by Apples blurb on it, keeping in mind this is the same company that just claimed that the Gen 3 Butterfly keyboard is 4X more durable....
“ Vega delivers an enhanced compute engine and utilizes 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 percent faster than the Radeon Pro 560X15 — for tackling demanding video, 3D, rendering, and compute workloads.”
But you can now run full Photoshop on the iPP, almost like a real computer
Edit: Unless they have greatly improved the ASK keyboard for the iPP, it’s a vinyl covered, mushy feeling, POS with no backlight or trackpad. It just has a terrible feel to it, at least the current ones do. Kind of “Oh geez, guess we gotta offer some kinda keyboard, what can we throw together real quick?”
