In Time Spy, the Alienware scores 7,446 to the EGPU's 7,629. Similarly in the hardcore Firestrike Ultra, the EGPU enables the Yoga to score a whopping 5,990 points to the 650 it gets on its own.Įven compared to the Alienware m15, the Yoga with an EGPU is looking quite nice. For instance, in Time Spy, the Lenovo Yoga C940 goes from 885 points all the way up to 7,629 when connected to the graphics box.
We tested that against the laptop without an EGPU, an Alienware m15 R2 with an Intel Core i7-9750H, an Nvidia GeForce RTX 2080 and 16GB of RAM, and finally, our test bench with an AMD Ryzen 9 3900X, 32GB of RAM and the same Nvidia GeForce RTX 2080 tested in the external GPU box.Īnd, when we just look at synthetic benchmarks through 3DMark, it's looking pretty good for the external GPU.
In order to test the performance of an Nvidia GeForce RTX 2080 on an EGPU, we paired it with a Lenovo Yoga C940 with an Intel Core i7-1065G7, 12GB of RAM and a 512GB NVMe SSD. This is the desktop system we used for comparisonĬPU: AMD Ryzen 9 3900X (12-core, up to 4.6GHz)
