The MSI HD 7770 Power Edition graphics card from AMD is built on the GCN 1.0 architecture and was officially introduced on 15.02.2012. At the core of the card is a chip created with modern lithography. The die houses 1.5 billion transistorsistors transistors, and its area is 123 mm². The core configuration includes 640 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. 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 nominal thermal design power is 80 W. For stable system operation, a PSU of 250 W or more will be required.
