Sapphire is working on a new custom-design Radeon HD 6970 2GB graphics card. This card will closely resemble the reference design from AMD but will feature a blue PCB and a custom cooling solution. Additionally, the card also has a rotary knob that lets you switch between two BIOS settings.
t 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.
