ATI showcased during last weekend's Texas Gaming Festival a Radeon X850 XT prototype with 512 MB of GDDR3 memory using dual-rank design. The company plans to offer 512 MB cards commercially soon. The prototype presented during the festival was set with the same frequencies as standard X850 XT cards: core at 520 MHz and memory at 1.08 GHz. A statement from the company assured that the 512 MB piece ensures higher perfomance even in current games and outperforms higher-end X850 XT Platinum Edition cards.
