In addition, half of the inventory bloat was due to ATI underestimating the yields on its wafer by a factor of roughly 40% (i.e., the wafers yielded 40% more die than expected), further compounding its inventory glut (under ATI s die buy model, ATI purchases on a per-die as opposed to per-wafer basis, implying that it has secured the price per die based on theoretical yields from the fab, and has committed to purchase the entire wafer no matter what the yield).
On rage.3d as well. Can't link now appears to be down.
