Dont forget Imagination have been bought by Apple ... (Apple is not really known for give the right price to IP ( basically they even lower the price as low they can ) ... ( this was the real start of the hostility with Samsung, as Samsung have collaborate with them ( Imagination ) for developp the gpu at start and from Scratch for include it in the A1-2-3-4-5 (easy to find in the pressnews room of the society ) ( Apple willing to buy all the company who have start build the hardware for them ( huum i should say who was work with Samsung ).
But this join exactly was i was saying, the gpu cost in a soc, licenced is really low ( enough for generate a good amount of money as we speak about hundred of millions of chip ) but still really low by units. ( on a sold prouct, the licence price is even lower ). But does they have the choice ?
