Source procured a slide presentation of AMD, which sheds light on the GPU under the symbol Tenerife. It is assumed that this model will follow Tahiti (Radeon HD 7970).
The basis of Tenerife is the "improved architecture Graphics CoreNext» or Graphics CoreNext 2.0. As stated, it is possible to increase productivity by 20% compared to Tahiti. The slide does not indicate the number of stream processors, but according to some, it is equal to 2304. I wonder what this is now the number of stream processors in the Radeon HD 7970. According to unconfirmed reports, up to 2048 in the serial product is reduced to increase the yield rate of products. This method is used by other manufacturers, for example, the GeForce GTX 480 is used by 480 CUDA cores of the 512 possible, and six-core processors Intel Sandy Bridge-E Core i7 obtained from the eight-crystals (in addition, they use only 15 MB of cache memory of 20 MB formed on the substrate).
Map based on the new GPU will have 3 GB of memory GDDR5. A typical value of power consumption is also not specified, but the card is in idle mode consumes only 3 Watts. The equipment products designed to connect up to six displays, video outputs include HDMI and miniDP.
It is expected that the new product will be released in the third quarter. Whether products based on Tenerife belong to series Radeon HD 7000 or they will open the series Radeon HD 8900 - one can only guess.
