The Mobility Radeon HD 4850 graphics card from ATI is built on the TeraScale architecture and was officially introduced on 09.01.2009. Thanks to modern manufacturing technology, engineers managed to place 1.0 billion transistorsistors transistors on a 256 mm² die. For graphics processing, 800 shader units are provided. The technological equipment is complemented by 0 RT Cores and 0 Tensor Cores. The memory subsystem features GDDR3 modules with a total capacity of 1 GB. The bus width is 256 bit bits, and the peak data exchange rate is 54.40 GB/s. The GPU's base clock speed is 503 MHz, and in Boost mode, it can automatically increase up to 0 MHz.
