AMD has rolled out its ATI Radeon HD 4830 graphics card, pitching the part as a low-cost entry into its top-of-the-line GPU range.

One of the first 4830-based boards out of the gate is Sapphire's HD 4830, which clocks the GPU to 575MHz and links the core to 512MB of GDDR 3 memory running at 900MHz and sitting on a 256-bit bus.

The GPU contain 640 unified shader processor. It supports DirectX 10.1 gaming and incorporates AMD's Unified Video Decoder (UVD) engine for dedicated picture streams encoded using VC-1 and H.264 - the two key Blu-ray Disc codecs.

In addition to the two dual-link DVI outputs and a TV port on the card, the Sapphire board comes with an HDMI adaptor that delivers both 7.1-channel audio and video output to an HD TV.

Sapphire also touted the new GPU's 24x custom-filter anti-aliasing and dynamic geometry acceleration, both intended to improve game performance and imagery. The 4830 is CrossFireX capable.

Sapphire wants £100 for the card.
