"The Radeon Pro SSG was demoed at the Siggraph computer graphics conference rendering raw 8K video smoothly at 30 frames per second, and AMD claims it can even run at 90 frames per second. VR content creators and the medical and scientific communities who need high-end renders would benefit the most from the large frame buffer the Radeon Pro SSG provides, and that's exactly who AMD is targeting."
