With CES in Las Vegas starting next week, ATI is likely announcing their budget graphics cards. Among them a DX 11 ready Radeon HD 5570. On a website some photo's however already leaked on this Redwood based GPU. The card you are looking at comes from the brand Unika and comes with a 128-bit memory bus an 1 GB DDR3 memory running at 1800 MHz.
Though it is unknown how many shader processors the card entails we do know that is runs at 650 MHz. The 5570 obviously is a budget card which in all its ways shows clearly (short PCB).
Our money would still be on a Radeon HD 5750 though, anyway have a peek.
