Previewed at CeBIT 2010, the Sapphire HD 5970 4GB Toxic Edition has 4GB of GDDR5 memory, a total of 3200 stream processors and 160 texture units and runs with clock speeds of 900MHz core and 1200MHz for memory (4.8GHz effective). This is significantly faster than the standard model.



With twice the computing power of the highly acclaimed SAPPHIRE HD 5870 series, this new HD 5970 model shares all the exciting features of the HD 5000 family – including support for the DirectCompute 11 instruction set of Microsoft DirectX 11, hardware tessellation and multi threaded communication with the system CPU. It also enables the acceleration of applications supported by ATI Stream, and the ability to display across three monitors simultaneously with ATI Eyefinity. All of this comes with a modest active power consumption and ATI PowerPlay Dynamic Power Management to achieve super-low power consumption in 2D and idle modes.

The card is cooled by a customised solution from Arctic Cooling with nickel plated heatpipes and fins, featuring three low-noise dual ball bearing fans and developed specially to mate with the Sapphire original design PCB. This efficient solution also provides scope for further performance tuning.
