We can blame manufacturers, they had the samples from both Intel and AMD and they could have chosen to provide an AMD high end option based on the results I am sure they obtained for themselves in testing and the design differences.
I think the main reason they did not bank on AMD was a perception that the market wants Intel for their high End devices, and AMD is perceived as the "cheap" option only. This has proven incorrect as the market has embraced the AMD due to its performance and technology. Who isn't interested in 7nm or the prospect of 5nm laptops? Some of us consumers understand what the reduction in NM will do to fix heat, throttling and improve battery and performance because we want to run intensive tasks regularly, has anyone seen an XPS review lately and just how terrible their performance is with Intel?
We are waiting for a high end AMD option. We are not going to buy Intel. We are not going to sacrifice screen quality or other quality elements to get into AMD. There is a market now and manufacturers should address that now. They are not getting my sale until they do, I'm looking at you Razer, Dell, Lenovo..
