The GIGABYTE RX 6800 XT GAMING OC (RDNA 2.0) model joined the AMD lineup of graphics accelerators on 28.10.2020. Thanks to modern manufacturing technology, engineers managed to place 26.8 billion transistorsistors transistors on a 520 mm² die. The core configuration includes 4608 shader units, 72 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. The GDDR6 video memory capacity is 16 GB. Thanks to the 256 bit-bit bus, bandwidth reaches 512.00 GB/s, eliminating delays when working with demanding textures. In standard mode, the core operates at 1850 MHz, but auto-overclocking technology allows it to reach 2285 MHz under load. The card's power consumption (TDP) is stated at 300 W. The manufacturer recommends using a power supply unit with a wattage of at least 700 W.
