Are there different versions of the 3060 in laptops?

A friend of mine claims that, but I can't find anything about it.

Different in that the TGP is different for all the RTX 3000 laptops. So the power consumption more or less, although a higher TGP is better because more can be done.

Is there.

Yes there's. The TDP is between 60 and 130 watts, depending on the version. This results in a massive difference in performance
