The Radeon HD 8770M (GCN 1.0) model joined the AMD lineup of graphics accelerators on 01.04.2013. Thanks to modern manufacturing technology, engineers managed to place 1.0 billion transistorsistors transistors on a 77 mm² die. For graphics processing, 384 shader units are provided. The technological equipment is complemented by 0 RT Cores and 0 Tensor Cores. The GDDR5 video memory capacity is 2 GB. Thanks to the 128 bit-bit bus, bandwidth reaches 72.00 GB/s, eliminating delays when working with demanding textures. The GPU's base clock speed is 775 MHz, and in Boost mode, it can automatically increase up to 825 MHz.
