The new HD 5550 Overclocked Edition works at 650MHz for the Redwood based GPU, has 2GB of DDR3 memory clocked at 2400MHz and feature 320 stream processors, DirectX 11 support and features DVI, HDMI and D-Sub outputs.
It is cooled by a rather small active cooler and takes up a single slot.
The new HD 5550 still isn't listed in Europe but we guess that it could end up with a price tag of around €100.
