The Radeon HD 6490M Mac Edition (TeraScale 2) model joined the AMD lineup of graphics accelerators on 02.05.2011. At the core of the card is a chip created with modern lithography. The die houses 0.4 billion transistorsistors transistors, and its area is 67 mm². For graphics processing, 160 shader units are provided. The technological equipment is complemented by 0 RT Cores and 0 Tensor Cores. The GDDR5 video memory capacity is 0 GB. Thanks to the 64 bit-bit bus, bandwidth reaches 25.41 GB/s, eliminating delays when working with demanding textures. In standard mode, the core operates at 750 MHz, but auto-overclocking technology allows it to reach 0 MHz under load.
