SAPPHIRE Adds two new HD 4890 Models with Vapor-X

SAPPHIRE Technology announces two new models of the SAPPHIRE HD 4890 - offering users a choice of performance and connection options and both featuring SAPPHIRE Vapor-X cooling technology for quiet and cool operation.

Following the recent announcement of the limited edition HD 4890 ATOMIC Edition – the first graphics card to deliver a 1GHz engine clock – SAPPHIRE now offers the HD 4890 TOXIC Edition based on the same high performance components but with slightly lower core clock allowing it to be more widely available. In addition, SAPPHIRE introduces the HD 4890 Vapor-X model, a SAPPHIRE original design offering near silent operation and for the first time providing Display Port as well as HDMI, VGA and dual-link DVI connectors all on the rear bracket.

The SAPPHIRE HD 4890 TOXIC uses the same configuration of Vapor-X and heatpipe cooling technology as the ATOMIC Edition. It is factory overclocked with a high speed core clock of 960MHz as well as 1GB of GDDR5 memory with clocks of 1050MHz to give stunning performance straight out of the box. Two dual-link DVI ports are provided as well as TV out. HDMI and VGA are supported with adapters.

The SAPPHIRE HD 4890 Vapor-X model is a new SAPPHIRE original design. It has SAPPHIRE’s Vapor-X cooling module on the GPU together with a heatsink and profiled fan venting heat out of the case. It is quieter and significantly faster than the standard reference model, with core clock speed of 870MHz and 1GB of DDR5 memory clocked at 1050MHz. Any two of the four output options can be used simultaneously, giving maximum flexibility for connection to different display types. An HDMI to DVI adaptor is also included for those who wish to use a pair of DVI monitors.

The Vapor-X series features high specification solid capacitors and SAPPHIRE ‘Black Diamond’ heatsink chokes for higher efficiency and more reliable operation. The high-polymer aluminium capacitors used have characteristics superior to regular aluminium capacitors for longer product life. The choke is an important component of the power regulation on a graphics card, and the SAPPHIRE Black Diamond (patent pending) choke with integral heatsink runs 10% cooler and with 25% more power efficiency than a normal choke.

The SAPPHIRE HD 4890 series is based on a new GPU core from the ATI division of AMD. This features the same graphics architecture as the successful HD 4870 series, with 800 stream processor units, 256-bit GDDR5 memory interface and integral hardware video decoder. It also features improved memory management architecture, and technical innovations that allow higher clock speeds and reduce standby power levels.

This series uses the PCI-Express Gen2 interface, and features dual connectors for CrossFireX cables, allowing two or more cards to be used together on a CrossFireX compatible mainboard for even higher graphics performance.
