The solution to increase graphics processing power for some laptops without a discrete graphics card is eGPU, this technology helps laptop Thin and light can play games and do heavy graphics. Let me find out about eGPU through this article.
1. What is eGPU?
The external GPU, also known as eGPU, is a set of external graphics cards for laptops that use video cards on desktop PCs to provide laptop performance to increase graphics rendering or gaming.
2. Common eGPU connection ports
Thunderbolt 2 is the specialized port available on the line MacBook Apple from 2015 onwards. This connection standard gives the bandwidth speed between eGPU and laptop up to 20 Gbps which is equivalent to the speed of 2500Mb / s. Because it is a specific gateway, eGPUs that use this gateway are often expensive.
USB Type C – Thunderbolt 3
The thunderbolt 3 standard is 2 times faster than thunderbolt 2 with 40Gbps equivalent to 5Gb / s, which reduces latency and higher performance than the eGPU using thunderbolt 2.
3. Is the performance of eGPU really good?
The power that eGPU gives to the laptop depends on the video card that is attached to the eGPU, the more you want the performance and processing speed, the stronger the GPU will be to meet your needs. In addition, you must use the right connection standard to bring the highest performance, the greater the bandwidth as you take full advantage of the performance on the video card. Usually you can only take advantage of 70% – 80% of the power of the video card available on the eGPU.
4. Notes when using eGPU
To get the most out of your power, you should use thunderbolt 3-connected eGPU models, and after connecting an eGPU to a laptop, you should install a driver for the video card. In addition, the choice of GPU mounted on the eGPU is also important because the stronger the video card will produce the higher performance.
