Just want to add that while the MI350P is a PCIe card, it is designed for servers. It just has a heatsink (with no fan) which the powerful full-case fans of a rackmount server are supposed to cool. So while the MI350P is certainly more attainable for us regular folk due to its formfactor, we won't be able to just drop it into our gaming PCs like a regular graphics card.

That being said, if you're dropping tens of thousands of dollars on graphics cards then picking up a rackmount case to go around the card is pretty insignificant.
