Graphics Cards

[Reyfox]

I have a RX 6700XT and use Vegas Pro for editing. In an era where there could be re-flashed cards sold as one thing but are really something else, I am curious as to why, with Vegas Pro's log file, gpu_video_x64.Log report I have 20 Compute Units when AMD's website says the card has 40 Compute Units. 

Is there an official way of knowing how many Compute Units a card actually has. All the other "numbers" for the card (RAM, speed, etc) seem to be accurate except Compute Units. Installed driver is 22.5.2.
