LGZS Platform Controller?
The current Intel processors apparently need a separate chip called an "LGZS Platform Controller" in order to connect a discrete GPU, the need for which some have speculated (most notably in an article at Arstechnica) is related to Apple not offering a 13" MacBook Pro with an i5 processor, with the reasoning going along the lines that there wouldn't be enough space on the motherboard to hold the rather large LGZS thingy, the rather large processor, and the similarly large discrete GPU. Apple doesn't want to give up the high performance discrete graphics, so it has to suffer along with the older Core2 Duo.
Now my vague understanding is that Sandy Bridge does a better job of integrating things, so perhaps the functions of the LGZS Platform Controller no longer require a separate chip. Does anyone know if this is the case?
Also, for what it's worth: I've driven across a bridge over the Sandy River east of Portland Oregon in the United States. Intel has a habit of assigning code names inspired by Oregon geography, so it seems plausible this bridge is the source of the name. Maybe some chip design team executive commutes across it every day. The bridge itself is a green steel truss bridge and is in a very scenic area near the Columbia River Gorge.
Evil Steve because I can't prove he isn't sticking with a C2D in the 13" MacBook Pro just to annoy me as revenge for me not buying an iPhone.
