Native Refresh Rate
The CX and A80J are both 120 Hz television sets.
This means that you can play games at 120 frames per second in 1080p and 4K if you have a PlayStation 5 system.
If you have an Xbox Series X, then you should be able to play games at 120 fps in 1080p, 1440p and 4K with the CX. For the A80J, you can play games at 120 fps in 1080p and 4K.
For the Xbox Series S, you can play games at 120 frames per second in 1080p and 1440p with the CX as well as 120 frames per second in 1080p on the A80J. In order to play games at 120 fps in 4K for both of these OLEDs, you need to get your own HDMI 2.1 cable as the Series S only comes with a HDMI 2.0 cable.
Adaptive Sync Support
The CX is the only OLED in this comparison to work with FreeSync (supported by AMD PC graphics cards), GSYNC (supported by NVIVDA PC graphics cards) in addition to Variable Refresh Rate (supported by Xbox Series S, Xbox Series X and, if the future, PlayStation 5).
While the A80J currently does not support any of the aforementioned adaptive sync features, Sony is expected to add Variable Refresh Rate via a future firmware update for the TV.
Input Lag
According to tests done by RTINGS.com, the CX has slightly lower input lag than the A80J when you compare the same resolution and refresh rate combinations.
With that said, both of these OLEDs should be very responsive when it comes to playing games on PC and consoles.
