Graphics Processing Units: Powering Visual Computing
A Graphics Processing Unit, or GPU, is a specialized electronic circuit designed to rapidly manipulate memory to accelerate image creation for display devices. Once focused on graphics rendering, GPUs have evolved into powerful parallel processing units capable of complex calculations and data-intensive tasks. Comprising thousands of smaller computing units called "cores," GPUs execute tasks simultaneously, making them efficient for parallel computing.
How do GPUs Work?
GPUs utilize a parallel computing architecture known as SIMD (Single Instruction, Multiple Data). This allows a single instruction to execute on multiple data points at once, enabling GPUs to perform numerous calculations in parallel.
GPUs excel in tasks that require massive parallelism, such as rendering 3D graphics or training complex AI models. They divide workloads into smaller tasks and assign them to individual cores, allowing for quick processing of large data sets and outperforming traditional CPUs in specific applications.
