AMD Radeon HD 7900 to offer new architecture and Rambus XDR2?

Posted on Monday, September 12 2011 @ 22:17:22 CEST by

Nordic Hardware heard rumors that AMD's Radeon HD 7900 series may use the new Core Next architecture and XDR2 memory from Rambus.
The information that has leaked on Radeon HD 7900 series says that AMD will pair the new architecture with XDR2 memory at up to 8000 MHz, which in the flagship would result in a memory bandwidth of 256 GB/s over a 256-bit memory interface, comparable to 176 GB/s in Radeon HD 6790 with GDDR5 memory at 5500 MHz.


The unconfirmed information says that the flagship Radeon HD 7970 (Tahiti XT) will ship with 2048 Radeon cores and a GPU frequency of 1000 MHz, which should result in a performance to remember, but despite that the power consumption will only be 190 watt, thanks to the new node technology. Radeon HD 7950 (Tahiti Pro) and Radeon HD 7990 (New Zeeland) are also mentioned. Where the latter is the first graphics card with dual GPUs based on the Graphics Core Next architecture.
