In all honesty i had thought the idea of an APU would of been something of this design with a Central processor attached. Cause for the card size even, you are getting a gpu and cpu for one card size. So you could process quicker within the processing chain, within two additional discrete cards, right? But for mobile graphics discretely to say, are probably very resourceful designs or uses for what they make and offer. Laptops to say have some requires additional to say a tower or PC.
As for Phyx to say is hard place though, given that anymore is more of just having another GPU then anything. Rather even on the mobile for ATI with Radeons, hard saying. There isnt much interest probably for them, when with another GPU or better can process more frame rates at higher details.
As say for the War continues is as speculative as saying probably there isnt a difference between a desktop card and laptop card, right? Or a Phyx card and GPU card. Rather ATI calls thiers Phyx i dont know.
