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
Not surprisingly, the first "Super RV770" product is already out. Diamond Multimedia teamed up with Danger Den and Smooth Creations to launch the "ATI Radeon HD 4870 XOC Black Edition".
I know the XOC has already been posted, but I dont think a lot of these details were included, plus I like how that last article talked about how MSI did all this custom work, seems like AMD/ATI has been behind this the whole time.
I was going to wait for the 4870 x2, but maybe I should wait for the 4870x2 XOC black edition.
