its Loadsamoney in every thread saying the same old tripe. the G81 is skipped, straight to G90, there is ONE article with no proof, no quotes, no anything at all to indicate its true whatsoever.
the G90, as the rumours go is exactly the bloomin same as the G81 but on a smaller process than the G80. that is all the G81 was going to be anyway, call it G81, G90, G14000, if its the same spec it does not matter what you will call it. the rumour goes that G81 was going to be 80nm, now its that the G90 will be 65nm and not to far away. even though TSMC has only just announced making 65nm edram, lower process's are far far easier to use on very very simple design couple million edram transistors and what, the G80 is over 700 million transistors and 100's of times more complex, theres no capacity or company in the world that seems capable of mass producing a 65nm high end gpu.
the only theoretical differences between G81/G90 would be process size, and therefore possibly clock speeds, and there was a guess then might fit a 512mbit bus in there, which would MATCH x2800xtx specs, not surpass or blow away, but MATCH.
fact is the 80nm process takes very little effort to impliment, 65nm is incredibly difficult, intel have a huge design team and it took them a couple years to go 90-65nm. amd are taking ages to go from 90-65nm, but nvidia, with a chip with more transistors will do it in just what, 6-10 months? bull, it probo will go 65nm for its next gen core, would be mad not to, but theres no facilities, and no time for them to make it anytime soon. the 80nm drop for very VERY little time and effort increases profits for them on their entire range. it makes no sense to keep making 90nm 8800 cards for the next 6 months while it doesn't have to.
