The Radeon 550X 640SP graphics adapter is based on the advanced GCN 4.0 architecture. AMD announced this model on 11.04.2018. At the core of the card is a chip created with modern lithography. The die houses 2.2 billion transistorsistors transistors, and its area is 103 mm². The core configuration includes 640 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 4 GB. The bus width is 64 bit bits, and the peak data exchange rate is 48.00 GB/s. The graphics chip operates at a base clock of 1019 MHz with dynamic acceleration capability up to 1071 MHz. The card's power consumption (TDP) is stated at 50 W. The manufacturer recommends using a power supply unit with a wattage of at least 250 W.
