Following the introduction of the highly acclaimed HD 4800 series, SAPPHIRE Technology is now shipping two new models of HD 4850 providing a further choice of price: performance points for the enthusiast.
The new SAPPHIRE HD 4850 1GB is a new version of the HD 4850 designed by SAPPHIRE for the user who demands more memory for specific applications like rendering. It offers similar overall performance to the standard model, with clock speeds of 625MHz (core) and 993MHz (memory).

Delivering higher performance to the enthusiast for only a small price premium over the standard model, the SAPPHIRE HD 4850 TOXIC Edition has been designed by SAPPHIRE to run significantly faster – shipping with core clock speeds of 675MHz and fitted with 512MB of high speed memory operating at 1100MHz. It also features a Zalman heatpipe fan, providing more efficient cooling - running at much lower temperatures than the standard design – as well as quieter operation and more headroom for performance tuning.
Both models use the PCI-Express Gen2 interface, and feature dual connectors for CrossFireX cables, allowing two or more cards to be used together on a CrossFireX compatible motherboard for even higher graphics performance. Both are based on the powerful new graphics architectures from the ATI division of AMD, incorporating 800 process units, improved memory management architecture and an upgraded hardware video decoder.

All SAPPHIRE graphics cards in the HD 4800 series incorporate the latest ATI Avivo™ HD Technology for enhanced Video display and feature a new 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.
