If you haven't received a VIN yet, I think it's extremely likely you're getting one with the AMD chip. With the AMD chip, the interface will likely be snappier. I heard that the browser is borderline unusable on the Atom chips.
That said, I think the thing that's more important to me is the Li-Ion 12V battery. I have heard stories about needing to replace the Lead-Acid battery every 3 years or so, which is really frequent compared to how often you need to replace the battery in ICE vehicles. Plus, not having to worry about being stranded if your 12V battery dies is something I really prefer to have.
