Of course, that's the non XT model. Materials obtained by VideoCardz indicate the AMD Radeon RX 6600 graphics card is scheduled to ship in October. 

Interested board partners who wish to submit cards for review must tell AMD by September 15th, and AMD will begin shipping cards to reviewers on September 29th. The Navi 23 GPU is used by the AMD Radeon RX 6600 with four compute units are turned off. This results in a total of 1792 Stream Processors. In addition, it has 8 GB gddr6 memory and a 32 MB Infinity Cache. As with the RX 6600 XT, AMD will most likely not release a reference design.

The review embargo would be October 13th at 9 a.m. Eastern Standard Time, the card should be available immediately.
