The two new models are only available in China for now and the single difference between the two is the material framing the screen and thus a slight weight reduction for the Air variant. Otherwise, both versions are powered by the Intel i5-11320H quad-core CPU coupled with 16 GB of LPDR4x-4266 RAM and 512 GB NVMe SSD, plus they feature a 14-inch 1440p 3:2 IPS LCD. They even integrate a Thunderbolt 4 connector, all for around $750.
