Back in February, the company Sapphire released a powerful graphics card HD 7750 Ultimate with a passive cooling system. At Computex, AMD general partner introduced her older sister, based on the faster Radeon HD 7770. The novelty is called Sapphire HD 7770 Ultimate and also uses a massive passive cooling system.
The cooling system was so large that the video turned out nearly equal in length Model 7900 Series. Despite the length of the video card is not much added to the volume and still only takes up two expansion slots in the system unit.
The frequency of the GPU Sapphire HD 7770 Ultimate is 1000 MHz, memory GDDR5, which is soldered 1GB with 128-bit bus running at a speed of 1125 MHz (4.50 GHz effective). The video card is based on 28 nm of the crystal "Cape Verde" with 640 GPUs CoreNext. In the sale of novelty will arrive later.
