Sapphire Unveils Small-Sized R9 285 2GB GDDR5 ITX Compact Edition Graphics Cards

Optimized energy efficiency offered by AMD Radeon R9 285 graphics adapters has become a key factor for Sapphire to elaborate a pair of original proprietary versions. The new-comers, codenamed R9 285 2GB GDDR5 ITX Compact Edition, are targeting mini-ITX systems with huge performance ambitions. The pair traditionally involves a standard model with etalon specifications and OC model with a factory overclocking.

Both graphics cards employ a small-sized two-slot cooler that consists of a compact heatsink, four copper heatpipes, and a single fan of 100 mm dimensional type. Connection with PC monitors and other visual solutions is realized by means of HDMI, DVI-I, and a couple of mini-DisplayPorts. Additionally, the models feature dual BIOS chips (standard and UEFI) which might be switched with the help of a dedicated key on the case.

To continue, Sapphire R9 285 2GB GDDR5 ITX Compact Edition and OC Edition are based on AMT Tonga GPU (28 nm, GCN) with 1792 stream processors, 112 …
