Although the AMD Radeon HD 7970 has been enjoying its time kicking the arse of virtually every other GPU in the world, the second GPU in AMD's 28nm-powered, GCN-busting lineup has been delayed.
AMD's Radeon HD 7950 won't reach us this month and has been delayed until February. A paper launch of the Radeon HD 7970 late last year is not the usual move for AMD, and they want to avoid similar problems with the HD 7950 when it launches, so a delay could actually be a good thing.
The Radeon HD 7950 is based on the same Tahiti core as the higher-end HD 7970 brother, except that 4 of its GCN (Graphics Core Next) compute units have been disabled. Because of this, it takes on the moniker "Tahiti Pro" versus the 7970's "Tahiti XT". The 7950 will sport 1792 streaming processors, 3GB of GDDR5 and a 384-bit interface. It should also feature the same amount of video outputs, allowing 6-screen support.
Right now, unknown information on the HD 7950 are total TDP, clock speeds and pricing. We should hopefully see some of these questions answered at CES 2012 next week where AMD have promised to fly me over to wine and dine me. I kid I kid, but a parcel full of HD 7970's would be nice.
