eGPU is a type of graphics processor that is useful outside the computer.
The full form of eGPU is ” External Graphics Processing Unit .”
These eGPU attach via a high-speed connection, such as Thunderbolt cable, which provides sufficient bandwidth to allow graphics to be processed outside the computer in real-time .
eGPUs can be used in both desktop and laptop computers.
They are used on most laptops because desktop PCs have internal expansion slots for graphics cards. In both cases, the main function of eGPU is to provide higher graphics processing performance to the connected machine.
Historically, graphics performance of a single computer becomes limited without expansion slots according to the speed of the built-in graphics card.
With the introduction of high-speed Thunderbolt 2 and Thunderbolt 3 interfaces, it is possible to render graphics in real-time using an external GPU.
The four components in an eGPU setup are the most prominent:
1. Computer2. eGPU enclosure या adapter
3. Video card (GPU)4. Cable
While it is possible that you can use a rudimentary adapter to connect an external graphics card, eGPU enclosures are mostly used because they protect the GPU and provide more reliable performance.
An eGPU provides enclosure for a connection video card (such as a PCI Express slot) and also has an interface for connecting with the computer, such as a Thunderbolt port.
Most eGPU enclosures support many different types of models video cards, which means that you can upgrade your card anytime.
Like an internal GPU, the graphics processor that is used in an eGPU must be supported by the operating system so that it can work.
This means that you may need to install the drivers before using it for eGPU.
NOTE: Apple added operating system-level support for eGPUs to macOS High Sierra10.13.4, which was released in March 29, 2018.
