The Mobility Radeon HD 3850 X2 graphics card from ATI is built on the TeraScale architecture and was officially introduced on 04.06.2008. The graphics processor is manufactured using a modern process. The 192 mm² die contains approximately 0.7 billion transistorsistors transistors. For graphics processing, 320 shader units are provided. The technological equipment is complemented by 0 RT Cores and 0 Tensor Cores. The GDDR3 video memory capacity is 1 GB. Thanks to the 256 bit-bit bus, bandwidth reaches 48.00 GB/s, eliminating delays when working with demanding textures. In standard mode, the core operates at 580 MHz, but auto-overclocking technology allows it to reach 0 MHz under load. The card's power consumption (TDP) is stated at 70 W. The manufacturer recommends using a power supply unit with a wattage of at least 0 W.
