AMD Radeon RX 6600 series has 8GB GDDR6?

Twitter leaker KOMACHI_ENSAKA spotted listings of several ASRock Radeon RX 6600 and RX 6600 XT video cards in the database of the EEC (Eurasian Economic Commission).

8GB memory and not 6GB or 12GB

Probably one of the most interesting observations here is that these cards feature 8GB GDDR6 memory -- and now 6GB or 12GB as was previously rumored. It also suggests these models don't have a 192-bit memory bus but a 128-bit bus.

The listing reveals ASRock plans Radeon RX 6600 XT Phantom Gaming D, P, and I models, as well as a Radeon RX 6600 Challenger series.

This isn’t the first time RX 6600 XT appears in ASRock EEC filing though. The company had already submitted RX 6600 XT 12GB model, but that was 3 months ago. The fact that the new listing shows 8GB memory, indicates that there has been a change in plans or the previous listing was simply inaccurate.

An exact launch date of the RX 6600 series remains unknown. Just like the Radeon RX 6700 non-XT, the RX 6600 lineup seems delayed due to the current GPU shortages.
