Sapphire is readying a new custom-design Radeon HD 6970 2 GB graphics card. The card uses a PCB that closely resembles the AMD reference-design PCB, but comes in blue color. It also uses a custom designed cooler that uses a traditional blower channeling air through a dense aluminum fin canal block. The most peculiar feature is a round rotary knob, which lets you switch between the two BIOS ROM chips on board, thereby letting you maintain two hardware-stored clock and fan profiles. This knob appears to be coin-turned. The Radeon HD 6970 packs 1536 VLIW4 stream processors, and connects to 2 GB of memory over a high-speed GDDR5 memory interface.
