eGPU – Connecting an external video card to a notebook (DIY implementation)
What about PhysX? Well, in case of games it is possible to dedicate the internal dGPU for PhysX and use the eGPU for graphics only as long as the dGPU is powerful enough to do that. Of course, the dGPU must be also a Nvidia card, AMD cards won’t work, and neither iGPUs (Intel Integrated video cards).
Setting the primary display we are ready to run some benchmarks to see how the external GPU compares to the mobile mainstream GPU (765m) inside the notebook. As you can see the performance almost doubles compared to what we could get without the eGPU.
