The RX 6600 non-XT would be Navi 23 “73FF:C7”, and the XT, would be “73FF:C1”. The leaker claimed that he was using a 21.4.1 driver that already featured RX 6600M support. This implies that the driver has been modified to support these graphics cards. The GPU-Z utility was recently updated to support both cards.
Clock speeds of the non-XT variant haven’t been listed by the GPU-Z utility yet, but the graphics card could have a clock speed of 1692/2684 MHz with a memory clock at 16 Gbps.
