AMD revealed at its Financial Analyst Day that the Trinity APU will enable system builders to ship $600 - $800 laptops with a thickness of only 18mm. A picture of such a system from Compal was published a couple of posts back.
"The 18mm reference design from Compal is what many OEMs are looking at. We believe that this will bring the ultra-thin form-factor into $600 - $800 price-point. This is [an evidence of] the value of APUs because you really have performance that you need at the power envelope that you need at the right price-point," said Lisa Su, general manager of global business units at AMD.
The 18mm thickness for a reference design of an inexpensive laptop is a remarkable achievement. For comparison: Apple Macbook Air is up to 17mm thick, Lenovo ThinkPad X1 is up to 21.5mm thick and the world's thinnest notebook - Samsung Series 9 900X3B - is 12.9mm thick. Unfortunately, AMD's reference design is made of plastic, whereas typical ultra-thin mobile PCs are made of metal. It is likely that AMD specifically recommends its partners to use inexpensive materials to ensure low price of its ultra-thin notebooks, but that will clearly affect quality.
