[EDIT]hmmm.....whats going on at AMD? (and history of 3Dfx Rampage)

Looks like it will be like the next HD 3870 (55nm) that AMD thought was going to rock the world vs Nvidia's 65nm 8800GT, as AMD released a dual-GPU 3870x2 about a month after the paper launch of a single-chip 3870, just in time for Xmas 2007.  Still, no dice at all as 8800GT took the spotlight, while NV didn't release a dual-chip 9800GX2 until many months later. 

Then AMD finally got the bigger 4870 ready on 55nm with first GDDR5 (which should've been called QDR instead of DDR) just in time for Nvidia's monolithic 65nm GTX 280.  The 4870 actually turned out to be a big success with the humble pricing - probably not something AMD would ever do again if greed continues to run rampant.  

AMD's compact 14nm Polaris vs Nvidia's 16nm Pascal...  history lesson: it doesn't matter which is smaller - what matters is price and performance.
