An external graphics processing unit, or eGPU, is a graphics engine. It is connected using a fast link, like a Thunderbolt cord, which offers enough capacity for graphics processing in real time away from the computer.

Both desktop and mobile PCs can use eGPUs. However, because desktop Computers frequently have integrated extension ports for graphics cards, notebooks are more frequently linked to them. In either scenario, an eGPU's main goal is to boost the linked machine's graphics working speed.

Four elements are necessary for an eGPU setup...

• eGPU enclosure or adapter
• Computer
• Cable
• Video card (GPU)

Although it is possible to attach an external graphics card using a crude adaptor, eGPU containers are more frequently used because they secure the GPU and offer more dependable performance. An link for attaching to the computer, such as a Thunderbolt connector, is provided by an eGPU case, which also offers a connection for the video card (such as a PCI Express socket).

The majority of eGPU containers accommodate a variety of video card types, allowing you to update the card whenever you like. Comparable to a native GPU, an eGPU's graphics engine relies on the operating system's assistance for it to function. This implies that before using the eGPU, software may need to be installed.
