The PowerColor LCS HD 6990 graphics card from AMD is built on the TeraScale 3 architecture and was officially introduced on 08.03.2011. Thanks to modern manufacturing technology, engineers managed to place 2.6 billion transistorsistors transistors on a 389 mm² die. For graphics processing, 1536 shader units are provided. The technological equipment is complemented by 0 RT Cores and 0 Tensor Cores. The memory subsystem features GDDR5 modules with a total capacity of 2 GB. The bus width is 256 bit bits, and the peak data exchange rate is 160.00 GB/s. The graphics chip operates at a base clock of 830 MHz with dynamic acceleration capability up to 0 MHz. The card's power consumption (TDP) is stated at 375 W. The manufacturer recommends using a power supply unit with a wattage of at least 750 W.
