Okay, I've heard this many, many,MANY times in the past few months, the 256 bit bus (in the GTX770 4gb-version) is not enough to use the entirety of the 4 gigs of vram in the gphx card. Can someone explain to me WHY this is so?
I have conflicting data, there is this one man(link shown)who says that the bus size is independent of the vram, to wit:
LINK!
But, as I am sure a lot of people who are reading this have read on many forums, there are numerous forums that downplay the 4gb vram on the GTX 770 4GB as an unnecessary addition and even on some places, gone so far as to say that the extra 2GB shows NO performance gain:
(I dont have a link to back up that last statement, but definitely remember reading it)
If it is true, then why do manufacturers continue making (and more importantly people continue buying) these extra GB cards like the GTX770-4GB or the GTX780-6GB? AND MORE IMPORTANTLY, if this is true, and if the rumour mill is to be be believed, why is nvidia making a 4gb GTX 980 with a 256 bit bus and, well whaddaya know, 4GB VRAM??
IF it is not true, why is it such a popular opinion among the masses?
