Introduction



PowerColor is one of the first ATI AIBs to release their own HD 4890 design called HD 4890 PCS it features a non-reference cooler and custom PCB .

AMD has made clear that RV790 will have plenty of overclocking potential, so PowerColor went all out and is shipping their HD 4890 PCS with stock clocks of 950 MHz core and 1100 MHz memory. As cooler a solution from Zerotherm is used. Last but not least, the voltage controller design has been changed as well, most probably to reduce cost significantly. All this results in a card that will not cost more than most reference cards: $249.
