can people not use a little common sense, a 680gtx, a 780gtx, a mustang 28, or a keplersuperdupafasterthan 7970.
The NAME is irrelevant, when people say 780gtx, or 680gtx, or BIG kepler, they are all referring to the same damn thing. The faster single core Nvidia gpu from the next gen.
It also wouldn't matter if a midrange is a fermi shrink, a fermi on 28nm with a lot more shaders, or a kepler on 28nm with more shaders.
We don't know the specs, or the performance, its guesswork, the names are for want of a better word(or maybe its spot on, I dunno) a place holder for the card we are all talking about.
Some generations AMD/nvidia rebrand old gen stuff with new gen names, sometimes they shrink old gen stuff on a new process and give it a new gen name then decide its unfair to call their "real" new gen that name and jump forward another step. AMD and Nvidia have both done every combination of every type of name change there is so predicting the final names based of almost certain low end 28nm parts being called 600 series is daft.
You could have 28nm low end 600 parts, and still have the high end new gen be 680gtx, you could have fermi 40nm low end 600 parts, and still have the high end Keplers be 680gtx. Guessing won't change the fact that the fastest biggest core will be the fastest biggest core, no matter how fast or what architecture it is, and same goes for the middle core.
Meh, I'm high(not fun, pain medication
) and I've seen probably 50 posts on "but but, I thought it was a 780/680/999999gtx/potatocakefishcard, it's peeing me off.
