this is getting ridicilous

I wouldn't exactly call any of the listed GPUs to be next generation, but more of a nice iteration between current and next.

Neither AMD nor NVIDIA can sell chips that their foundry cannot produce. We will see 20nm GPUs when they are able to be manufactured and pushed to retail. It isn't as though the designers are intentionally limiting themselves at the moment, as I'm sure they would like the freedom to put more transistors where they need them as much as you want to see that done.
 
Well everything is made by TSCM(Taiwan Semiconductor Manufacturing Company). All AMD and nVidia GPU's, plus a bunch of chips for smart phones(Apple ect...).

The whole industry will(better) be making the move to 20nm soon. Early 2014 hopefully! And I'll agree with Ridiculous! 28nm tech dates to late 2011. The 7970 is extremely long lived! But you may agree that tech(hardware) is "finally" mature(fast) enough that it has some longevity. It has taken decades and billions of dollars, to get where we are today.

Check out the little table on Wikipedia, dating back to 1971. 20nm isn't listed, as this table is inline with Intel and their CPU's. Ah, fond memories(not really) of my old Pentium 4 (1.7 GHz), even brand new that Windows XP based rig was slow.

Pentium 4 sucked :kaola:
 

I guess AMD could always go back to GlobalFoundries for their GPUs, but... I seriously doubt that would get them to smaller process nodes any faster. TSMC and GlobalFoundries have both had issues. Intel are the only ones who seem to just keep trucking.
 


late 2011?? big deal lol, everyone expects things to be released faster these days and they bitch about it... and then things get released too soon and they have problems and people bitch some more... why not just accept it as it comes... unless ofcourse u guys wanna do it yourself lol
