it's useless for the majority of people, because ethe cost of the laptop and this enclosure with rtx 4090 will be much expansive than custom pc with rtx 4090.
and in my opinion even when there are certain cases for this. I still can't see the value of it.
VideoCardz already has an article that tested the 4090 in an eGPU enclosure, and it says it can be up to 20% less powerful.
BUT,
if it end up to be noticeably faster than a 175W 4090 Laptop, this might finally be a viable solution.
Not surprised knowing how crazy efficient the 40 series are.
Only idiot would buy this... for that crazy price I would build whole PC with 4090 !!!
