They all have the same size
Asus has introduced the first GeForce RTX 40 Prime video cards, which meet Nvidia's recommendations for SFF Enthusiast GeForce computers.
Let us remind you that we are talking about Nvidia’s initiative to popularize compact gaming PCs in the SFF format. Also, some sources call it Nvidia GeForce SFF-Ready.
One way or another, all Asus video cards with this nameplate are 50 mm thick and 269 mm long. That is, they are quite compact by modern standards. True, there are no top adapters in the line. So far there are only three such cards: RTX 4060 Ti, RTX 4070 and RTX 4070 Super. All three have the same cooling system with three fans.
There are no specific details about each model yet, but other than their sizes, they hardly stand out in any way. Perhaps we'll see more Nvidia GeForce SFF-Ready products at Computex 2024.
