This GPU model is based on the Navi 33 XL die, so I'm almost certain that there might an RX 7600 XT GPU also in the pipeline, which would be using the Navi 33 XT core die.
After all, the previous gen RX 6600 used the Navi 23 XL GPU, and the RX 6600 XT came equipped with Navi 23 XT. BTW, some custom AIB models will have a peak boost clock of up to 2.85 GHz.
This card doesn't seem much like a huge upgrade over the RX 6600 though. Although the effective bandwidth is 477 GB/s that accounts for 2'nd Gen Infinity Cache, but it is not much higher that the 413 GB/s bandwidth on RX 6600. Rest of the specs are similar, including the memory bus width at 128-bit.
