You're describing the Thinkpad T14S. It's a real shame it has soldered RAM, I hope Framework's success will show the industry there's an actual need for this.
I guess you're right, hadn't realized the AMD Thinkpads were now available with better than 1080p screens. Totally agree on the soldered RAM crap. Also would be great to buy from a more consumer-friendly company like Framework, especially if they are going to do things like support coreboot.
It doesn't seem to have a proper 14 inch HiDPI display. 1080p on 14 inches usually needs anywhere from 1.2x to 1.4x scaling and 4K would need around 2.5x scaling.
