What is an eGPU and how does it work?
An external graphics processing unit (eGPU) is a device that provides additional graphics processing power to a computer, allowing for improved performance and capabilities. An eGPU works by connecting to a computer via a high-speed interface, such as Thunderbolt 3, and utilizing the computer’s existing graphics processing unit (GPU) to offload graphics-intensive tasks. This allows for improved performance, reduced lag, and increased capabilities in applications that rely heavily on graphics processing.
In an eGPU setup, the computer’s existing GPU is used as a primary graphics processor, while the eGPU provides additional processing power to handle more demanding tasks. This allows for improved performance in applications such as gaming, video editing, and 3D modeling, among others. Additionally, eGPUs can be used to upgrade older computers with older GPUs, effectively giving them a new life and extending their useful lifespan.
Do I need Thunderbolt 3 to use an eGPU?
Thunderbolt 3 is not the only interface that can be used to connect an eGPU to a computer, but it is one of the most popular and widely supported.
