You can bet your bottom dollar that GK110 had completed the prototyping phase well and truly before kepler was ever released and could have been rolled out as a GTX680 if Nvidia pleased. What happened was once kepler tapered out and the HD7970 was released, Nvidia saw the potential of GK104 and made the decision to shelve GK110 from GeForce production......in other words, they could have used GK110, however GK104 was strong enough, and much cheaper to manufacture and as such, GK104 became the GTX680 as it performed on par with Tahiti XT and cost considerably less to manufacture (this means higher profit margins for Nvidia).
GPU chips aren't like shoes, they don't get manufactured, shoved in a box, then sent in a shipping container on a boat on the same day. The production ready designs are completed well in advance of product shipment dates and Nvidia would have had an idea of GK104 and GK110 performance months before the GTX680 was released and once they saw the Tahiti XT performance numbers, it made economical and business sense to go with the GK104 chip for the GTX680.
So just because the Tesla GK110 cards weren't released until November, that doesn't mean that GK110 wasn't ready for mass production well and truly in advance, it simply means that Nvidia made the smart business decision and used a cheaper product that performed more than adequately.
So much fail in this reply.
a) In I+D environments, as soon as the product is done, you put it out. Everyday the tech is ready but not into the market you are losing money, since you allow your competition to catch-up. Would you invest hundreds of millions into a product and, then, wait a year to release it? Really?
b) Any CEO not following a) strictly would get fired by their shareholders any minute. Do you have any idea why products get revisions? Or bugs? Because all companies in I+D related industries work against the clock and any minute the product is not out there is a ton of revenue lost.
c) Do you truly think that GK110 didn't get released early even for Tesla when such cards have a HUGE mark-up and there was a TON of expectation?
Conclusion: you are clueless. NVIDIA, and any other tech-company that has competition around it, will release every product the single minute they can, and not a minute later. Why did GK110 come that late? Because it wasn't ready: be it that it was too expensive, or the fab couldn't keep up or whatever reason: it wasn't ready.
