How Do GPUs Work?

Graphics Processing Units (GPUs) are highly parallel processors optimized for throughput rather than latency. Unlike CPUs, which are designed for diverse sequential tasks with a few complex cores, GPUs contain thousands of simpler, lightweight cores that excel at executing the same instruction across many data elements. For example, a modern NVIDIA A100 GPU has 6,912 CUDA cores, compared to a CPU with typically 8–64 cores. This massive parallelism makes GPUs indispensable not just for rendering graphics but also for scientific simulations, cryptography, and modern artificial intelligence training.
