they were aldready detailed earlier this month, Sapphire has now officially announced its two versions of the new Radeon HD 7950 card. The base model will feature a single fan while the OC version will end up with a much beefier dual fan cooler.
As far as the specs go, both models will pack 1792 stream processors packed in 28 GCN compute units and 3GB of GDDR5 memory paired up with a 384-bit memory interface. The base model ends up working at AMD's reference clocks of 800MHz for the GPU and 1250MHz (5GHz) for memory. The OC version on the other hand got boosted to 900MHz for the GPU although memory remained at reference 1250MHz.
The Dual-X cooler on the OC version packs two fans that cool a rather hefty heatsink connected to the copper baseplate via five copper heatpipes.
Both cards are already available with a suggested price tag of US $449 for the base version and US $479 for the OC one.
