I think it’s money. nVidia is selling same chips on different boards for different prices. An example from the current generation, $800 GeForce 4070 Ti, and $2500 L4 are based on the same chip. The difference between these two cards is amount of VRAM, some settings which control clock frequencies, and these legal/software limitations. Without the legal limitations, people who need to compute stuff which fits in 12GB VRAM would only pay them $800 for the GeForce model.
