One indication that it may not be SMIC is that Huawei spelled out the process node (5nm) on the product page. They did not do that for 9000S. But it may not be the exact 9006C from the older laptop either. My reasoning is because the product page for the new laptop is a copy paste of the old one. All the specs, features, images, processor name (9006C 5n) is the same. It looks like they just only changed laptop model number. So the question is why would they change the model number if the resulting product is not going to have any performance difference with the old one. So my thinking is if it's not a newly fabbed chip then it may also not be the exact old 9006C either. So this could be another TSMC-era chip just labelled as 9006C.
