As I said in my first post, the smart money was always going to be on it being a variant of the desktop GM204 - which is exactly what it is.Fantastic news and all the comments made to me at the beginning of my post, l can say l have been vindicated although the name is not as expected.
All eyes on Pascal now - and I wouldn't mind betting Nvidia do the same again, offering a crippled version of the midrange chip, then an uncrippled version at a later date.
