The Radeon HD 7770 GHz Edition graphics adapter is based on the advanced GCN 1.0 architecture. AMD announced this model on 15.02.2012. Thanks to modern manufacturing technology, engineers managed to place 1.5 billion transistorsistors transistors on a 123 mm² die. For graphics processing, 640 shader units are provided. The technological equipment is complemented by 0 RT Cores and 0 Tensor Cores. The memory subsystem features GDDR5 modules with a total capacity of 1 GB. The bus width is 128 bit bits, and the peak data exchange rate is 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.
