have been quite a few rumours recently regarding AMD's mobile lineup and in addition to the already announced 40nm rebrand 7000M series parts, guys from Anandtech managed to score some more details regarding the 28nm GCN based ones that should carry HD 7700M, HD 7800M and HD 7900M series brands.
According to the post, AMD's Tahiti GPU will remain as a desktop-only GPU while the mobile lineup will be based on Pitcairn and Cape Verde 28nm GPUs. The rebranded parts were already seen running at CES and it is a matter of time before these start to show up in notebooks from various manufacturers, while the 28nm GCN parts will apparently wait for April/May timefrime.
Of course, both Pitcairn, which should end up the fastest 28nm mobile GPU and will certainly pack a decent punch as well as full support for DirectX 11.1, AMD's Video Codec Engine and ZeroCore.
