The SPARKLE Calibre GTX 680 Captain graphics card from NVIDIA is built on the Kepler architecture and was officially introduced on 22.03.2012. Thanks to modern manufacturing technology, engineers managed to place 3.5 billion transistorsistors transistors on a 294 mm² die. For graphics processing, 1536 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 256 bit-bit bus, bandwidth reaches 192.30 GB/s, eliminating delays when working with demanding textures. The GPU's base clock speed is 1124 MHz, and in Boost mode, it can automatically increase up to 1189 MHz. The card's power consumption (TDP) is stated at 195 W. The manufacturer recommends using a power supply unit with a wattage of at least 450 W.
