Graphics cards for laptops typically come in several designs. For laptops with a more compact design, it will use a thin and light MXM (Mobile PCI Express Module) design, but still use the PCIe interface directly.
Recently, another new design that is thinner and more compact was shown, and it seems to use the M.2 storage interface. For this "new" graphics card, it is an NVIDIA GeForce RTX 4050 graphics card that uses three M.2 connections to connect to the motherboard components of a laptop.
The uniqueness of using a graphics card with this design is that it can be installed and removed easily, and the M.2 slots on the motherboard can be used to increase the amount of storage on the laptop.
It is expected that Lenovo will be the first laptop maker to use the NVIDIA GeForce RTX 4050 graphics card with this design.
