That strategy doesn't win though. The enterprise is going to buy the enterprise GPU anyway because they're spending someone else's money and it's a tax write off and the enterprise GPUs are faster and have ECC memory in addition to having more VRAM. But giving something for hobbyists to play with is how you build an ecosystem. So not only do they get higher margins on their consumer GPUs, they get more code written for their architecture, which lets them sell more of the expensive GPUs.

Not doing that is making a mistake.
