Latest rumors claim that AMD is preparing a March launch for the RX 6700 XT mid-range gaming cards, even though Team Red is among the companies that have been hit the hardest by the global semiconductor shortages. This will most likely be another rushed paper launch to counter Nvidia's RTX 3060 release.

There is a mistake in your 6600M description. It says 1792SPs, but 24CUs. Obviously, 1792/64=28CUs, not 24. Also, 28CUs makes way more sense, as cutting 32CU Navi23 to just 24CUs (and for the midrange 6600M) is too much, this is almost Navi24 territory.
Thanks, was a typo, yep it's supposed to feature 28CUs = 1792 cores.
