The GeForce 845M (Maxwell) model joined the NVIDIA lineup of graphics accelerators on 26.08.2015. Thanks to modern manufacturing technology, engineers managed to place 1.0 billion transistorsistors transistors on a 77 mm² die. The core configuration includes 384 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. The graphics card is equipped with 2 GB of GDDR5 memory. A 64 bit-bit bus is used, providing bandwidth at 40.10 GB/s. The graphics chip operates at a base clock of 1071 MHz with dynamic acceleration capability up to 1150 MHz. The nominal thermal design power is 33 W. For stable system operation, a PSU of 0 W or more will be required.
