While CPUs excel at sequential tasks, GPUs contain thousands of cores that execute the same operation simultaneously across multiple threads. AI training relies heavily on matrix multiplications—repetitive operations ideal for parallel processing. The SIMT (Single Instruction Multiple Threads) architecture enables warp scheduling, where the GPU instantly switches between thread groups to maximize utilization and avoid idle time. This design keeps thousands of workers continuously active, explaining why AI training requires massive GPU clusters. ## Full article daily.dev links to this article rather than hosting it.
