MSI, unfortunately for them, has leaked confidential AMD information to the press. This information gives us details on the roadmap for the rest of the HD 7000 series of cards. It first of all reaffirms what we’ve already seen, that the HD 7970 will launch on the 9th of January (which it did) and that the HD 7950 will launch on January the 31st (which it did). It also disappoints by telling us the HD 7990, the dual GPU card of the HD 7000 series, is still under development and its launch date has not been decided yet. It also tells us that the HD 7870 based on the Pitcairn XT core will come in to replace the HD 6870 in March. The HD 7850 will come in to replace the HD 6850 in March too but this one is based off the Pitcairn Pro core. Both both of these 78X0 cards will come with 2GB of GDDR5 memory.
The HD 7770 will come along with the HD 7750 on February the 15th. These will be direct replacements for the 6770 and 6750. Both will come with 1GB of GDDR5 memory and are based on the Cape Verde XT and Cape Verde Pr0 cores respectively. AMD is not at this time seeking to make a direct HD 6790 replacement according to this document, although a HD 7790 may come at a later date.
