The ASUS HD 7770 DirectCU OC V2 graphics card from AMD is built on the GCN 1.0 architecture and was officially introduced 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 core configuration includes 640 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. 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 nominal thermal design power is 80 W. For stable system operation, a PSU of 250 W or more will be required.
