ASUS announced the Radeon R9 285 Strix graphics card, based on AMD's latest 28 nm "Tonga" silicon. The card utilizes ASUS' latest Strix cooling solution, which stays silent until a thermal threshold is reached, only beyond which, its fans begin to spool up. Barring its new cooler shroud design and fan-speed management, the Strix cooling solution bears strong resemblance to the company's DirectCU II cooling solution. ASUS is shipping the card with a factory-overclock. Based on the 28 nm "Tonga" silicon, the R9 285 from AMD features 1,792 stream processors, 112 TMUs, 32 ROPs, and a 256-bit wide memory interface, which holds 2 GB of memory on this card.
