>>70174725Depending on how the connection bandwidth is set up, they can either perform as expected or not so well.PCIe 2x is not good, even for low-end cards. 4x is acceptable, but not as ideal as 8x. PCIe 4.0 should fix those issues, because each lane will be twice as capable.For laptop users, I assume this is a godsend. The best cards you can fit inside them are expensive to make compared to ATX-compliant cards, and also will never run at full spec.
>>70175522I realize that I should specify that 8x isn't really possible with current designsAlso I mean that the best cards you can fit in the laptop itself, not the external case.
