Where are you getting that less than $50 for a mobile 7900m series GPU? To get one of those in a laptop is a several hundred dollar upgrade. I understand that those companies need to make a profit but I highly doubt it only costs $50 for a high end mobile GPU. Unless you show me some reputable figures Im not buying that number.

That was the cost for each part in the last gen GPU in 55nm and 40nm... the 7900M chip uses a 28nm process... so even cheaper... I can't see any AMD GPU in 28nm costing more than $50.
Even the huge and expensive GTX 285 (GT200, 500mm^2) cost less than $90... and NVIDIA sold the videocard per $350 in the market.

Anyway I expect the CPU + GPU + ESRAM + "Special Sauces" of Durango to be less than 250mm^2 in 28nm... not a huge chip.
