The XFX HD 7870 (GCN 1.0) model joined the AMD lineup of graphics accelerators on 05.03.2012. Thanks to modern manufacturing technology, engineers managed to place 2.8 billion transistorsistors transistors on a 212 mm² die. For graphics processing, 1280 shader units are provided. The technological equipment is complemented by 0 RT Cores and 0 Tensor Cores. 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 1000 MHz, and in Boost mode, it can automatically increase up to 0 MHz. The card's power consumption (TDP) is stated at 175 W. The manufacturer recommends using a power supply unit with a wattage of at least 450 W.
