The RTX A400 carries 6 second-generation RT Cores and 24 third-generation Tensor Cores, giving it AI acceleration and ray-traced visuals in a space-efficient design. Up to four displays connect from the single card, and the compact structure means it fits into a workstation chassis that could not accommodate a full-height professional GPU.

NVIDIA RTX Experience adds workstation productivity tools including desktop recording up to 8K and automatic notifications for new NVIDIA RTX Enterprise driver updates. The CUDA parallel computing framework runs C/C++ and Fortran natively alongside OpenCL, OpenACC and Direct Compute, deep learning frameworks such as TensorFlow and MXNet are accelerated by the cuDNN, cuBLAS and TensorRT libraries, and a 49-bit unified virtual address space migrates data between CPU and GPU memory.
