According to source? 168mm^2 Combined CGPU + 45mm^2 ED-Ram = 213mm^2 total

Vs Jasper: 135mm^2 CPU + 121mm^2 GPU (256mm^2) + 64mm^2 ED-Ram = 320mm^2 total

Vs Xenon: 176mm^2 CPU + 182mm^2 GPU (358mm^2) + 80mm^2 ED-Ram = 438mm^2 total

So roughly speaking its 34% smaller than Jasper overall in combined CGPU die sizes and 53% smaller than the original CGPU. The overall die sizes appear to follow the same trend although I haven't calculated the percentage changes. One would expect that what we are seeing here is a combined 45nm die as seen on the leaked roadmaps. I suspect the ED-Ram has also been shrunk although its difficult to say whether its 45nm, 55nm or 65nm.

Tease.
