Everyone is excited about the launch of Nvidia's GeForce RTX 3000 Mobile Series GPU based on the Ampere architecture. From the information provided to us by Nvidia, we only know of three models: GeForce RTX 3080, 3070, and 3060 mobile series GPUs. This statement is only partially true, Nvidia as a provider of the GPU only has three models, but this time, Nvidia partners have been given more freedom to modify the cards for the use case. With all this in mind, not every RTX 3000 series mobile GPU is created equally.

Wait... How many variants could there possibly be then? According to the most recent ComputerBase report, there are a whopping 28 variants of the RTX 3000 series mobile GPUs. In reality, not every GPU is exactly the same because of the silicon, but they are within a small margin of each other. This time around the GPUs have larger gaps in the specifications and performance based on the partner who modified them.
