The XFX Double D HD 7870 graphics adapter is based on the advanced GCN 1.0 architecture. AMD announced this model on 19.11.2012. Thanks to modern manufacturing technology, engineers managed to place 4.3 billion transistorsistors transistors on a 352 mm² die. The model's computational arsenal includes 1536 universal processors. Also available are 0 specialized cores for ray rendering and 0 cores for accelerating artificial intelligence. The graphics card is equipped with 2 GB of GDDR5 memory. A 256 bit-bit bus is used, providing bandwidth at 192.00 GB/s. The GPU's base clock speed is 925 MHz, and in Boost mode, it can automatically increase up to 1000 MHz. The TDP level for this model is 185 W, so for a build, it\'s advisable to choose quality cooling and a power supply unit of at least 450 W.
