The central processing unit (CPU) and the graphics processing unit (GPU) handle different types of data. The CPU is used in almost all devices including computers, cellphones, tablets, smartwatches and TVs. It deals with processing general information on the device, making sure software is running correctly. While the GPU  complements the CPU, it handles complex workloads like supercomputing, AI, machine learning and extensive data analysis where numerical precision is required. 

The COVID-induced chip shortage led global chipmakers to search for alternatives to standard chips to help ensure a steady supply of semiconductors. At the same time, companies are constantly searching for more efficient ways to cut costs and improve productivity at the chip level. The data processing unit, or DPU, has emerged as a complement to CPUs and GPUs to help. The DPU offloads communication networking from the CPU or GPU to help optimize workload for cloud and data centers, and get help reduce the cost by reducing the workloads of more expensive GPUs and CPUs.
