The purpose is to position products in a way that avoids a negative impression, in a manner that might impact sales. I would not be surprised to hear that OEMs view this quirk product positioning in a positive light. It doesn't take much to imagine a customer thinking to themselves "Why are the laptop CPUs only in the 2000's when the desktop CPUs are in the 3000's? I'll wait and buy later." So AMD wants to position the current-best available products in each market segment as the current generation numerically, branding-wise, without respect to manufacturing process details. Most consumers don't know what a "process" or "architecture" is anyway. Then the nerds who track these things, such as ourselves, will complain, but we won't be fooled by it. If that seems to you like taking advantage of people, then yes, that is exactly what they are doing. Intel dodges this problem (at least for the last 4-5 years) by shipping their mobile SKUs on a new march or process first, and the nerds waiting on DIY Desktop parts their "8th Gen" or "9th Gen" or whatever later.
