Having hit the 1.00 GHz (core) mark with its recently-introduced Radeon HD 4890 Atomic Vapor-X, Sapphire still finds the need for a card with the Vapor-X cooler sans the factory-overclocking, leaving some headroom for enthusiasts to play with. The new HD 4890 Vapor-X uses a non-reference blue PCB, along with the Vapor-X cooler similar to that on the HD 4870 Vapor-X model. A vapor-chamber plate makes direct contact with the GPU. It conveys heat to a radial heatsink cooled by a central fan. The memory is cooled by heatsinks, while the VRM-area is cooled by a heatsink of its own.
Sapphire uses AMD reference clock speeds: 850 MHz (core), and 975 MHz memory. The card features 1 GB of GDDR5 memory. Its outputs are care of DVI, D-Sub, HDMI and DisplayPort connectors provided right on the card. The card will reach retail in a few weeks' time.
