Introduction



Earlier this year AMD launched their Radeon HD 7800 Series. The GPU, Pitcairn, is a downscale from the HD 7900 "Tahiti" silicon, which introduced AMD's new Graphics Core Next architecture. Targeting a wide price-range between $250-$350, the HD 7800 series falls into the market-segment both AMD and NVIDIA have known to refer to as the "sweetspot" segment. Apart from 1280 stream processors, Pitcairn has 80 Texture Memory Units (TMUs), 32 ROPs (Raster Operations), and a 256-bit wide GDDR5 memory interface, holding 2 GB of memory.



Sapphire's HD 7870 Flex uses the AMD Reference clocks, but comes with a unique feature. It is able to support three DVI/HDMI monitors without the need for an active DisplayPort adapter. This make life easier for users who plan to use EyeFinity.
