![]() This post focuses on eGPUs on Ubuntu Linux. The folks over at eGPU.io maintain a list of the best laptops for eGPU applications.ĮGPUs are supported on Windows and Linux. ![]() ![]() Laptop manufacturers can design laptops with fewer than four lanes though, so you should consult the laptop manufacturer to find out how many PCIe lanes are available using Thunderbolt 3 on your machine. Thunderbolt 3 is a hardware interface that works over USB-C and supports up to four PCI Express (PCIe) lanes between the host CPU and devices such as GPUs, which gives you a theoretical maximum: 4 x 8Gbps (the bandwidth of a single PCIe Gen3 lane) = 32 Gbps Making sure that your laptop supports Thunderbolt 3 The performance of an eGPU solution depends largely on the performance of the GPU, performance of the CPU, and connection bandwidth between the two. With a single Thunderbolt 3 cable, I can connect my laptop to a powerful, dedicated GPU multiple monitors and peripherals. Most enclosures provide all of these, so all you need to use them is a laptop with Thunderbolt 3.īecause I value the portability of a thin and light laptop but want the raw horsepower of a dedicated GPU to get serious work done, eGPUs allow me to get the best of both worlds. A Thunderbolt 3 connection to the laptop.With the introduction of Intel Thunderbolt 3 in laptops, you can now use an external GPU (eGPU) enclosure to use a dedicated GPU for gaming, production, and data science.
