The Radeon HD 7970M graphics card from AMD is built on the GCN 1.0 architecture and was officially introduced on 24.04.2012. Thanks to modern manufacturing technology, engineers managed to place 2.8 billion transistorsistors transistors on a 212 mm² die. The core configuration includes 1280 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. The graphics card is equipped with 2 GB of GDDR5 memory. A 256 bit-bit bus is used, providing bandwidth at 153.60 GB/s. The GPU's base clock speed is 850 MHz, and in Boost mode, it can automatically increase up to 0 MHz. The TDP level for this model is 100 W, so for a build, it\'s advisable to choose quality cooling and a power supply unit of at least 0 W.
