Radeon HD 5550 Ultimate, 1024MB, 128-bit DDR2, 1600 MHz, HDMI, VGA, Dual Link DVI Heatpipe technology cools new mainstream graphics card in silence
The SAPPHIRE HD 5550 ULTIMATE is equipped with 1GB of DDR2 memory, with clock speeds of 550MHz core and 800MHz effective for the memory. It has 320 Stream processors and supports Microsoft DirectX 11 as well as accelerating applications compatible with ATI Stream. The PCB is a SAPPHIRE original design and the whole graphics system is cooled by a heatpipe based wrap-over heatsink. It has no fan, so is totally silent in operation and maintenance free.
This model has the output configuration of DVI, HDMI and VGA, the most flexible combination of monitor outputs and allowing the use of HDMI enabled monitors or digital TVs to be directly driven with both video and sound signals over a single HDMI cable. As the core technology is low power, no external power connection is required, making this series ideal for system upgrades or mainstream PCs that do not have high end power supplies.
