The GeForce GT 645M graphics adapter is based on the advanced Kepler architecture. NVIDIA announced this model on 01.10.2012. The graphics processor is manufactured using a modern process. The 118 mm² die contains approximately 1.3 billion transistorsistors transistors. The core configuration includes 384 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. The DDR3 video memory capacity is 2 GB. Thanks to the 128 bit-bit bus, bandwidth reaches 28.80 GB/s, eliminating delays when working with demanding textures. The GPU's base clock speed is 709 MHz, and in Boost mode, it can automatically increase up to 780 MHz. The nominal thermal design power is 32 W. For stable system operation, a PSU of 0 W or more will be required.
