The Diamond HD 7970 GHz Edition graphics card from AMD is built on the GCN 1.0 architecture and was officially introduced on 22.06.2012. At the core of the card is a chip created with modern lithography. The die houses 4.3 billion transistorsistors transistors, and its area is 352 mm². The core configuration includes 2048 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 3 GB. The bus width is 384 bit bits, and the peak data exchange rate is 288.00 GB/s. The graphics chip operates at a base clock of 1000 MHz with dynamic acceleration capability up to 1050 MHz. The nominal thermal design power is 300 W. For stable system operation, a PSU of 700 W or more will be required.
