Sapphire
Sapphire wprowadza na rynek dwie nowe karty graficzne: HD 4890 i HD 4890 OC Edition. Radeon HD 4890 jest nowym rdzeniem ATI, opartym na architekturze znanej z chipsetu HD 4870. Jest tak samo wyposażony w 800 procesorów strumieniowych, 256-bitowy kontroler pamięci oraz zintegrowany sprzętowy dekoder wideo. Poprawie uległo zarządzanie pamięcią oraz wprowadzone zostały ulepszenia umożliwiające osiągnięcie wyższych częstotliwości taktowania i obniżenie ilości pobieranej energii w trybie 2D.
Sapphire HD 4890 posiada wyższą wydajność w porównaniu ze swoją poprzedniczką HD 4870. W przypadku HD 4890 taktowanie rdzenia i pamięci wynosi odpowiednio 850 MHz i 975 MHz (3,6 GHz efektywnie), natomiast w przypadku HD 4890 OC Edition – 901 MHz i 1000 MHz (4 GHz efektywnie).
Karty graficzne HD 4890 współpracują z bibliotekami DirectX 10.1. Sugerowana cena detaliczna Sapphire HD 4890 wynosi 1050 zł brutto, natomiast cena wersji podkręconej HD 4890 OC Edition zostanie ujawniona w drugiej połowie kwietnia. Obie karty objęte są 2-letnią gwarancją producenta.
