Is the combination with Bluetooth only essential difference between RTL8821AE and RTL8812AE?

*If* the undermentioned two devices are based on RTL8812AE chipset,
whether they supported via 'rtl8821ae.ko' & 'rtl8821aefw.bin'?

Both RTL8812AE and RTL8821AE have wifi and Bluetooth. There is a difference in 
the radio structure. The 8812 has the potential to handle 867 Mbps - the 8821 
only half that rate. In any case, driver rtl8821ae handles both devices, and the 
firmware is the same. One other difference is that I have not tested the 8812 as 
I only have 8821 devices.

One other difference is that the firmware can handle BT coexistence internally 
in the 8821, but not in the 8812. Realtek is still working on getting a method 
of handling that problem. None of the Realtek Bluetooth adaptors has a driver in 
the kernel. Fixing that issue is my current project.
