The GeForce 845M graphics card from NVIDIA is built on the Maxwell architecture and was officially introduced on 07.02.2015. At the core of the card is a chip created with modern lithography. The die houses 1.9 billion transistorsistors transistors, and its area is 148 mm². The core configuration includes 512 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. The graphics card is equipped with 2 GB of DDR3 memory. A 64 bit-bit bus is used, providing bandwidth at 16.02 GB/s. In standard mode, the core operates at 863 MHz, but auto-overclocking technology allows it to reach 863 MHz under load. The card's power consumption (TDP) is stated at 45 W. The manufacturer recommends using a power supply unit with a wattage of at least 0 W.
