The Inno3D GT 640 graphics card from NVIDIA is built on the Kepler 2.0 architecture and was officially introduced on 29.05.2013. The graphics processor is manufactured using a modern process. The 87 mm² die contains approximately 1.0 billion transistorsistors transistors. The core configuration includes 384 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. The GDDR5 video memory capacity is 1 GB. Thanks to the 64 bit-bit bus, bandwidth reaches 40.06 GB/s, eliminating delays when working with demanding textures. The GPU's base clock speed is 1046 MHz, and in Boost mode, it can automatically increase up to 0 MHz. The card's power consumption (TDP) is stated at 49 W. The manufacturer recommends using a power supply unit with a wattage of at least 200 W.
