Thunderbolt 3 based eGPUs have been around for many years, offering the ability to plug a full desktop-class GPU into a laptop. Theoretically it’s an appealing idea, especially if someone is using an older laptop that has a perfectly fine CPU to handle games, but the GPU is long in the tooth. But there are some drawbacks.In this video I talk about my experiences using an eGPU over the past 4 months to play 10 of the biggest games from the past couple of years. Each game was tested in four different ways, and below are the specs of the equipment I used—all of which is covered in the video.

Dell XPS 15 7590 specs:

15.6-inch 4K OLED panel
Intel 9th-gen Core i9-9980HK
Nvidia GeForce GTX 1650
32GB DDR4/2666
1TB Samsung NVMe M.2 SSD

eGPU setup:

Asus XG Station Pro ($330 from B&H PhotoRemove non-product link)
Nvidia GeForce RTX 2070 Super Founders Edition ($856.80 from AmazonRemove non-product link)

As you can see in the video, the 2070 Super inside this eGPU offered higher frame rates than the GTX 1650 in the XPS 15 in almost every game. The 8-core Core i9-9980HK was also able to perform with higher clocks for longer periods, because it didn’t have to share cooling with the GTX 1650. The improvements would be even more dramatic on older laptops with out-of-date video cards.To read this article in full, please click here
