After seeing all the issues surface with not requiring vendors to list the exact specifications of the GPU, NVIDIA has now changed their stance. As we covered earlier, there were a whopping 28 variants of RTX 30 series mobile cards. XMG was the frontrunner in working to fix this issue being the most transparent of the bunch having the specifications available from day 1. ASUS followed by releasing them yesterday, but now NVIDIA is requiring all vendors to list the exact specifications of the cards on the laptops.

Before this change, manufacturers did not have to show the specifications of the card like the TGP and clock speeds. This move made the consumer's experience of buying a laptop much more difficult because they did not know what they were getting. A laptop with an RTX 3080 from MSI is not the same as it is from ASUS. The differences weren't made clear to the buyer. The only way to get a clear picture is through plenty of research and looking for reviews.
