Radeon HD 7970 is a powerful solution from AMD based on the GCN 1.0 architecture, released on 09.01.2012. 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. For graphics processing, 2048 shader units are provided. The technological equipment is complemented by 0 RT Cores and 0 Tensor Cores. The GDDR5 video memory capacity is 3 GB. Thanks to the 384 bit-bit bus, bandwidth reaches 264.00 GB/s, eliminating delays when working with demanding textures. The graphics chip operates at a base clock of 925 MHz with dynamic acceleration capability up to 0 MHz. The card's power consumption (TDP) is stated at 250 W. The manufacturer recommends using a power supply unit with a wattage of at least 600 W.
