Graphics Processing Unit (GPU)

A massively parallel processor, originally for graphics, that accelerates the matrix math behind AI training and inference.

Definition

GPUs contain thousands of cores plus specialized Tensor Cores and high-bandwidth memory, delivering far higher throughput than CPUs on parallel workloads. Data-center GPUs such as NVIDIA H100, H200, B200 and B300 are the dominant AI accelerators.

Exam tip

CPUs excel at sequential, branching tasks; GPUs excel at parallel matrix math.
