They come with the 780M and 680M processors, respectively, and both are outperformed by the 980M at a lower power draw [0]. Theoretically a consumer can't put these parts directly in a pc there's already a mini-pc with the laptop part 980M [1]. The 7800G sometimes shows up in mid-range and high-end gaming PCs with discrete graphics cards [2], which makes so little sense that I wonder if AMD quietly offloaded them in bulk at a steep discount to vendors.
I've commented on this before [3], can anyone shed light on the situation?
