But Thunderbolt 3 already exists, and both Intel and Nvidia support it. Intel does not have any discrete GPUs of their own, of course, but they did open up Thunderbolt 3 to external GPUs. Nvidia drivers have already been updated to support external GPUs over Thunderbolt 3. Thunderbolt 3 external GPU enclosures are still rare, but products such as the Razer Core are on the way and should work with any laptop that supports Thunderbolt 3, of which there are a growing number. There should be nothing stopping AMD from supporting eGPU enclosures via Thunderbolt 3. I'm honestly perplexed why they think we need yet another competing standard.
