在gaf那个良率问题/降频贴里，有人贴出了这样一张图片。。

In the Xbox picture provided by Mistercteam on SemiAccurate above, the power to Kryptos is via a CPU and a GPU power plane (right of the Kryptos chip) and 9 separate but identical bucky phase additive switching regulators; 4 for CPU and 5 for GPU. What's puzzling is that it looks like the CPU has 4/5ths of the max power the GPU would have. Two jaguar CPU packages should be about 4 watts while a 12 CU GPU should be over 50 watts. ??

Is the CPU side also feeding special chips or mistercteam is correct and there is a big cpu in there we haven't heard about? Could this explain the overheating? In any case the GPU and CPU can be powered separately.

但这里有让人抓头的地方，cpu/gpu的供电部分居然如此接近？？cpu的功耗不是很低么？？

在电源部分那只是9个滤波电容吧。。。

参考最下面一项，cpu部分的tdp为30w对吧？
