An upcoming NVIDIA Ampere GPU with board number PG133A has just passed RRA certification (Kopite via Videocardz). Since PG132 is the board number that AIBs will use, this is likely the Founders Edition card that NVIDIA will ship themselves. Since it has just passed RRA certification, it is also likely that this card will be available shortly. We have previously seen the wacky new design from NVIDIA for the RTX 3080 and we believe this is it.

Korea's RRA certification is required for every IC that is going to be made available to the public and usually one of the most prominent indicators of an imminent release (although it can show up anywhere from a month to 6 months before release). This particular PG number is in line with the part numbers that we know belong to the NVIDIA Ampere lineup.
