ive been hearing apple transitioning nvidia graphics cards, , hope not case.
looking @ apple current high end mobile gpu amd 6770m runs on pcie 2.1x16 @ 17.4 gtextures/s
equivalent on nvidia's side 555m runs pcie 2.0x16 @ 12 gtextures/s
looking @ new crop of gpu chipsets presumably make next mbp amd 7750m , nvidia 635m
amd 7750m runs on pcie 3.0x16 @ 40.2 gtextures/s
nvidia 635m runs pcie 2.0x16 @ 16.2 gtextures/s
if use higher nvidia card info has not released yet, won't take advantage of new pcie 3.0 , won't match anywhere near amd claiming.
thought reason apple went amd because of nvidia's poor graphics performance seem continuing...i hope reports wrong.
the "i hear" relates macpro refresh makes sense, since software requires level of horsepower requires cuda means nvidia. , since nvidia's kepler gpu in channel it'a timed match up.
