PowerColor is working on a Non-Reference HD 4890 PCS graphics card. PCS is short for Professional Cooling System, as such you can expect the product to have a unique cooler. The GPU is cooled by a Zerotherm cooler with a large central fan, and aluminum fins to which heat is moved around by four heat-pipes.

Also the product will come factory-overclocked. As such the card will come with default high clock speeds of 950/1100 MHz (core/memory) versus the reference speeds of 850/975 MHz. To be able to manage this apparantly TUL (PowerCOlor) is making a special non-reference PCB design. The new PCB will be 10-layer PCB and comes with a more simple Voltage Regulation management area.

Up-to this moment pricing isn't shared, but judging from the design and specs .. it will not be cheap.
