Date added: 01/03/2012 PCPerspectives - Does AMD have a 2304 stream processor GPU in waiting?

The review for the AMD Radeon HD 7970 3GB card based on the Tahiti GPU and the new Southern Islands architecture was released on December 22nd with expected availability on January 9th.  In that review we show a diagram of the Tahiti GPU and its 32 Compute Units (CUs) that combine to form the total 2048 stream processors (SPs).  

We asked and asked, but a die shot was never given to us for our review - a very non-standard practice for new launches.  That started us wondering - was there something AMD was hiding from reviewers about the architecture?  Were there some disabled CUs on the 28nm GPU that they had disabled for business, yield or clock speed reasons?  Think of what Intel has done with Sandy Bridge-E or what NVIDIA did originally with the GTX 480 GPU.  

AMD assured us that was not the case - Tahiti is the full die enabled, 32 CUs and 2048 SPs.
