The following information is not very detailed, that is because everyone has to keep a non-disclosure agreement. Even the ‘unknown Chinese’ sources are keeping their mouths shut. But nevertheless ORB-Hardware decided to share a fresh info about upcoming mid-range GeForce 600 cards. It seems that few of them will be released in May.

ORB-Hardware:
I can tell you less than I know, because I promised to keep the NDA. Server SweClockers notes that Nvidia will soon show something new. Everything started on the Nvidia facebook with teaser “Its coming”. Yes, something is really coming. In the coming weeks we can expect few new cards … more details later.

UPDATE: Head on to this article for GTX 690 release date!
So which cards can we expect for sure? Well, most probably the first card we will see is GeForce GTX 690, a dual-gpu zombie killing machine. Then we are pretty confident about GTX 670 coming right after. We actually don’t know if the Ti model will come simultaneously with non-Ti, so we shouldn’t expect it right now. Further, I’d say that GTX 660 release is quite possible – that’s the most anticipated card for many people (Obviously not for our readers – we like high-end card don’t we? But that’s the most popular graphics cards segment right now). It’s also quite possible that NVIDIA will present their GeForce GTX 650 GPU. Usually those GTX x50 cards are not very different from GTX x60, also it’s about time for NVIDIA to respond to AMD’s HD 7800 and 7700 Series. But those are only rumors, maybe you have a better idea, or some leaked information you’d like to share with us, then write a comment.
