It's not uncommon for a laptop to be connected with an independent graphics card. It can be done with a docking station. However, Lenovo has made a hard core transformation on a new air 14 version, and connected a RTX 3090 through an adapter.
Xiaoxin air 14 does not support thunderbolt 3, so it can't use the general external graphics card docking station (ASUS also released the PCI channel)It uses an m.2 transfer line and uses the PCI protocol.
In addition, this notebook does not have a unique display,A m.2 2242 slot is reserved to install the adapter cardIn order to install the rear shell, the engineer was still in a terrible situationCut a hole on D side with a cutter.
Finally, the new air connected with RTX 3090 lights up smoothly, and you can see that the system memory is 16GB, while the graphics memory of the graphics card is 24GB.
Compared with the RTX 3090, 3dmark time spy can achieve 17890 graphics score, which is less than 8% lower than RTX 3090 on desktop platform, but still higher than RTX 3080.
"Cyberpunk 2077" is also very smooth, even if you open the light chase, there is no Caton.
In addition, due to the priority of the bandwidth of the PCIe, a display is connected to the RTX 3090 through the DP data line, and the laptop's own screen is not used (of course, it can be used, but the performance will be lost).
In addition to hands-on ability, the cost of this system transformation is not high except for the RTX 3090,The connecting line is only over 200 yuan.
