I am going to get a NVIDIA GeForce RTX 3060 Ti and an eGPU chassis for my computer. I have a MacBook Air (I Know NVIDIA isn't supported for macOS) and use the eGPU on bootcamp.
I have heard that your CPU can bottleneck GPU performance. The main reason why I am purchasing this GPU is to increase Blender Cycles render times. How much bottleneck will my CPU have on this GPU?
Intel Core i5 8210Y (1.6 GHz, Dual-Core, 4 threads)
8 GB LPDDR3 2133 MHz RAM
MacBook Air (Retina, 13-inch, 2019)
