The Radeon HD 7450A graphics adapter is based on the advanced TeraScale 2 architecture. AMD announced this model on 05.01.2012. Thanks to modern manufacturing technology, engineers managed to place 0.4 billion transistorsistors transistors on a 67 mm² die. The model's computational arsenal includes 160 universal processors. Also available are 0 specialized cores for ray rendering and 0 cores for accelerating artificial intelligence. The memory subsystem features GDDR3 modules with a total capacity of 1 GB. The bus width is 64 bit bits, and the peak data exchange rate is 12.80 GB/s. The graphics chip operates at a base clock of 625 MHz with dynamic acceleration capability up to 0 MHz. The nominal thermal design power is 25 W. For stable system operation, a PSU of 0 W or more will be required.
