The Sapphire HD 4850 X2 2 GB graphics adapter is based on the advanced TeraScale architecture. ATI announced this model on 07.11.2008. The graphics processor is manufactured using a modern process. The 256 mm² die contains approximately 1.0 billion transistorsistors transistors. The core configuration includes 800 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. The GDDR3 video memory capacity is 1 GB. Thanks to the 256 bit-bit bus, bandwidth reaches 63.68 GB/s, eliminating delays when working with demanding textures. In standard mode, the core operates at 625 MHz, but auto-overclocking technology allows it to reach 0 MHz under load. The TDP level for this model is 250 W, so for a build, it\'s advisable to choose quality cooling and a power supply unit of at least 600 W.
