The GeForce GT 640M LE (Fermi) model joined the NVIDIA lineup of graphics accelerators on 04.05.2012. Thanks to modern manufacturing technology, engineers managed to place 0.6 billion transistorsistors transistors on a 116 mm² die. For graphics processing, 96 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 50.24 GB/s, eliminating delays when working with demanding textures. The GPU's base clock speed is 753 MHz, and in Boost mode, it can automatically increase up to 0 MHz. The card's power consumption (TDP) is stated at 32 W. The manufacturer recommends using a power supply unit with a wattage of at least 0 W.
