The MSI HD 7770 Twin Fan OC (GCN 1.0) model joined the AMD lineup of graphics accelerators on 15.02.2012. The graphics processor is manufactured using a modern process. The 123 mm² die contains approximately 1.5 billion transistorsistors transistors. 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 graphics card is equipped with 1 GB of GDDR5 memory. A 128 bit-bit bus is used, providing bandwidth at 72.00 GB/s. In standard mode, the core operates at 1000 MHz, but auto-overclocking technology allows it to reach 0 MHz under load. The TDP level for this model is 80 W, so for a build, it\'s advisable to choose quality cooling and a power supply unit of at least 250 W.
