The Sapphire HD 7950 Dual-X Platinum Edition graphics adapter is based on the advanced GCN 1.0 architecture. AMD announced this model on 22.06.2012. Thanks to modern manufacturing technology, engineers managed to place 4.3 billion transistorsistors transistors on a 352 mm² die. The core configuration includes 1792 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. The memory subsystem features GDDR5 modules with a total capacity of 3 GB. The bus width is 384 bit bits, and the peak data exchange rate is 240.00 GB/s. 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.
