Well, the description doesn't match what they claim to be selling. Hard to say if they actually have the 4080 16" laptop or a 17" laptop with a 4070 in it.
"Please do not compare with anything not on amazon.com."
Why are comparisons being restricted to Amazon?
As noted by @Eximo Amazon's descriptions and other information does not match.
You could find other mismatches, errors, etc. by making comparisons via other source websites.
My last big purchase (and literally my last big purchase) via Amazon was a power tool.
The tool I received was likely refurbished and not new as I ordered and paid for. And next day delivery = 2 weeks. Tracking simply stopped somewhere.... RMA'd after discovering some problems with the new tool.
I am now all the more leery of Amazon's product descriptons etc..
Comparing Amazon offerings to other Amazon offerings is a bit inbred as I now view it all.
