Sapphire stuns the competition with Radeon HD 4830

Oct 23, 2008 2:50 AM CDT

SAPPHIRE Technology, the leading manufacturer and worldwide supplier of AMD/ATI based graphics solutions has just introduced a new lower cost model in its successful HD 4800 series of graphics accelerators breaking new ground in 'bang for the buck'.

The new SAPPHIRE HD 4830 shares the award winning graphics architecture from the ATI division of AMD used in the existing HD 4800 series and offers the same features, but with an optimised specification and lower price point to deliver the best performance in its class.


The SAPPHIRE HD 4830 has a revised core with 640 stream processors clocked at 575MHz and is loaded with 512MB of GDDR3 memory, clocked at 900MHz. This specification delivers performance set to run even the most demanding next-generation HD games with support for Microsoft DirectX10.1 and enhanced anti-aliasing (AA). Equipped with AMD PowerPlayTM technology, this card optimises power consumption depending on usage.

Like the other members of the HD 4000 series, the SAPPHIRE HD 4830 uses the PCI-Express Gen2 interface, and features dual connectors for CrossFireX bridge cables, allowing two or more cards to be used together on a CrossFireX compatible mainboard for even higher graphics performance.

All SAPPHIRE graphics cards in the HD 4800 series incorporate the latest ATI Avivo HD Technology for enhanced Video display and feature a second generation built in hardware UVD (Unified Video decoder) considerably reducing CPU load and delivering smooth decoding of Blu-ray and HD DVD content for both VC-1 and H.264 codecs, as well as Mpeg files. In addition to two, dual-link DVI outputs, and TV-Out, a dedicated HDMI adaptor delivers both audio and video output on a single cable for direct connection to an HDMI ready display.

SAPPHIRE HD 4800 series graphics cards are Microsoft Windows Vista Premium certified and supported by the ATI Catalyst suite of software, ensuring customers have ongoing access to software updates for performance, stability and added features. Like the previous generation, these cards support DirectX10.1 for enhanced rendering performance and lighting effects.
