Taiwan's TUL Corporation today launched its PowerColor PCS HD4850 2GB graphics card, becoming the first company to offer home users a video card with as much memory. Part of the HD4800 series launched late last month, the PowerColor PCS HD4850's RV770 core chip is rated at 663MHz. The HD4850 card is also available in 512MB and 1GB GDDR3 memory sizes but it's the 2GB version that will allow the most room for textures and improve performance at higher resolutions, resulting in smooth, fast-moving graphics. The flagship card features a maximum memory bandwidth of 57.6GBps, further enhancing performance. All three cards will support 7.1-channel surround audio via a built-in HDMI port and are PCI Express 2.0 compatible.

Gamers running AMD's processors can expand their system's performance thanks to ATI's CrossFireX technology, which allows two or more discrete graphics cards to work together. The HD4850 cards feature Microsoft's latest DirectX 10.1 API.

The company's professional cooling system (PCS) and proprietary fan control design will detect the chip's temperature and adjust fan speed to control it accordingly. PowerColor has not announced pricing or on-the-shelf dates for the new graphics cards.
