It’s hard to determine with certainty which cards were confiscated as they lack the stickers and branding we are used to seeing. This video shows they do not have any video outputs, leading us to believe these are indeed Nvidia CMP series cards.
The release of the CMP 30HX and 40HX was scheduled for March, but only the former has been found on sale. Since no CMP 40HX cards have been seen on the wild so far, the confiscated cards are most likely the former.
