Because it is the Cpu that consumes the power budget, not the gpu. The gpu is actually very clean and extremely efficient. (it is a complete marvell... far exceeding the efficieny of SB or any other gpu we know at the moment). They need the high voltages to get yields on the cpu, not the gpu. While it probably would do better without the gpu in the yield department. BD is also suffering issues on the 32nm node. So doubling the llano cores, adding fast l3cache will explode on the current process.... Currently having 50W for 4cores@2,6GHz with proper yields is pushing it for llano.... try double that, add cache and 1,5Ghz and see where that would get you. (most likely to a nuclair generator as power supply..).Originally Posted by xdan
Why you just put Llano in comparision, Llano has 40% of the die GPU that's why it has that TDP, not to mention that doing GPU on SOI was wery hard. Llano problems will be much lighter on a cpu design without GPU.
I am not talking about the possibilities on a good working process, because that would affect BD also in a positive way.
