TG Daily claims AMD has developed a AIB/OEM-only product codenamed "Super RV770". This graphics card has an unlocked BIOS and has pre-installed watercooling to allow big overclocks:
The "Super RV770" will arrive with pre-installed water-cooling and features unlocked BIOS, which enables the GPU to be pushed all the way to 950 MHz, while the memory can be pushed to 4.8 GT/s (1.2 GHz QDR). According to our sources, you may be able to push the GPU even beyond 1 GHz, if you use TEC elements, and keep the temperature of GPU low.
At 4.8 GT/s, the "Super RV770" can achieve a bandwidth of 150 GB/s, taking the crown from the GeForce GTX 280. The RV770 chip has a 256-bit (32-byte) interface, which means we can calculate the bandwidth in the following way:
ATI RV770: 32-byte x 4.8 Billion Transfers/sec = 150 GB/s
Nvidia GT200: 64-byte x 2.2 Billion Transfers/sec = 138.37 GB/s
