Graphics Processing Unit - specialized hardware designed for parallel processing that accelerates AI training and graphics rendering. Like having thousands of workers doing calculations simultaneously instead of one at a time.
Training large AI models on GPUs can be 100x faster than using regular CPUs because GPUs can process many calculations at once.
All major clouds provide GPUs primarily through VM/compute offerings. AWS, Azure, GCP, and OCI let you run GPU-accelerated workloads (AI training/inference, rendering, HPC) by selecting GPU-enabled instance/VM types (or attaching GPUs on GCP). Differences are mainly in available GPU models, networking/storage options, and regional availability.
