PowerColor previously established an RX 6600 XT category on its website two weeks ago by accident, but there's more to come. At least three versions currently seem to have been developed and they've been posted at an etailer.
The card is scheduled for August 11th, although AMD probably will not offer a model reference. Eight gigabytes of GDR6 are all available on the PowerColor Fighter, Hellhound, and Red Devil, two of which are factory overclocked. the accurate frequency is not known yet.
The pricing appears to be a placeholder, the prices of cards are most probably not correct. A heavy price for a lesser card, 1250 Australian dollars can be exchanged to 780 euros, especially when PBTech, the same dealer, offers 6700 XT available at the same price. The initial delivery date would be September 16, although no specs have been added yet.
