Sapphire HD 7950 Dual-X with Boost is a powerful solution from AMD based on the GCN 1.0 architecture, released on 22.06.2012. Thanks to modern manufacturing technology, engineers managed to place 4.3 billion transistorsistors transistors on a 352 mm² die. For graphics processing, 1792 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 240.00 GB/s, eliminating delays when working with demanding textures. The graphics chip operates at a base clock of 850 MHz with dynamic acceleration capability up to 925 MHz. The TDP level for this model is 200 W, so for a build, it\'s advisable to choose quality cooling and a power supply unit of at least 550 W.
