An “AMD Confidential” slide was leaked by OBR-Hardware recently regarding a new “World’s Fastest GPU, Based on the Enhanced GCN Architecture”. According to the slide, “Tenerife” is expected to contain 1.2x the compute power of the current¬†performance¬†king, the AMD Radeon HD7970, GCN 2.0 architecture, and and 3GB of GDDR5 on a 384-bit memory interface.

Additionally, according to OBR-Hardware, “Tenerife” will pack 2304 stream processors, the memory will run at a clock speed of 6GHz, and it should be coming around Q3 this year or Q1 2013.

As usual, this is just a rumor only, so take all this information with a grain of salt. OBR-Hardware also touches upon the dual GPU HD7990, which they claim will not be released in Q1 or Q2 as originally planned. More information at the link below.
