The Dataland HD 7770 Dual Cool (GCN 1.0) model joined the AMD lineup of graphics accelerators on 15.02.2012. Thanks to modern manufacturing technology, engineers managed to place 1.5 billion transistorsistors transistors on a 123 mm² die. The model's computational arsenal includes 640 universal processors. Also available are 0 specialized cores for ray rendering and 0 cores for accelerating artificial intelligence. The GDDR5 video memory capacity is 1 GB. Thanks to the 128 bit-bit bus, bandwidth reaches 72.00 GB/s, eliminating delays when working with demanding textures. In standard mode, the core operates at 1000 MHz, but auto-overclocking technology allows it to reach 0 MHz under load. The card's power consumption (TDP) is stated at 80 W. The manufacturer recommends using a power supply unit with a wattage of at least 250 W.
