[CENTER][IMG]http://media.bestofmicro.com/AMD-AMD_Radeon_HD_7900-XDR2_Rambus_Memory,3-M-307282-13.jpg [/IMG][/CENTER] Additional information leaked has the Radeon HD 7970 series with, 2048 Radeon Cores, GPU frequency of 1000 MHz and XDR2 memory at 8000 MHz, which would result in a memory bandwidth of 256 GB/s over a 256-bit memory interface. This compared to the 176 GB/s in Radeon HD 6790 with GDDR5 memory at 5500 MHz. All this power will be packed within an estimated power consumption of 190 watts [CENTER][TABLE="class: editorTblTablecenter editorTblSize70 editorTblStyleStyle3, width: 433"] [TR] [/TR] [TR] [TD]TSMC 28nm HP[/TD] [TD]TSMC 28nm HP[/TD] [TD]TSMC 40nm[/TD] [/TR] [TR] [TD]GCN[/TD] [TD]GCN[/TD] [TD]VLIW4[/TD] [/TR] [TR] [TD]Tahiti XT[/TD] [TD]Tahiti Pro[/TD] [TD]Cayman XT[/TD] [/TR] [TR] [TD]32[/TD] [TD]30[/TD] [TD]24[/TD] [/TR] [TR] [TD]2048[/TD] [TD]1920[/TD] [TD]1536[/TD] [/TR] [TR] [TD]1000 MHz[/TD] [TD]900 MHz[/TD] [TD]880 MHz[/TD] [/TR] [TR] [TD]128[/TD] [TD]120[/TD] [TD]96[/TD] [/TR] [TR] [TD]64[/TD] [TD]64[/TD] [TD]32[/TD] [/TR] [TR] [TD]2GB XDR2[/TD] [TD]2GB XDR2[/TD] [TD]2GB GDDR5[/TD] [/TR] [TR] [TD]8000 MHz[/TD] [TD]7200 MHz[/TD] [TD]5500 MHz[/TD] [/TR] [TR] [TD]256 bit[/TD] [TD]256 bit[/TD] [TD]256 bit[/TD] [/TR] [TR] [TD]256 GB/s[/TD] [TD]230 GB/s[/TD] [TD]176 GB/s[/TD] [/TR] [TR] [TD]190 watt[/TD] [TD]150 watt[/TD] [TD]250 watt[/TD] [/TR] [/TABLE] [/CENTER] There looks to be some interesting times ahead for AMD in the coming months for us to keep watch. AMD will be releasing its new "Bulldozer" architecture, along with the new GCN architecture for the 7900 series GPUs (if the information leaked is accurate).
