I'm same with the i7-7500U on my XPS 13. It's an example of Intel market segmentation where the most expensive isn't really any better, and i'm looking forward to my next Ultralight work laptop being an AMD job - the better graphics will be nice too.
If you're using Linux for work, be careful with AMD - I had no end of trouble with the video drivers. Everytime the kernel updated the screen would only be black with the drivers installed. I had to go through an elaborate process of uninstalling the drivers, booting in safe mode so the video settings wouldn't also black out, run updates, and then make several attempts to get the drivers back in. Happened for both Debian and Red Hat distro variants, and I never found a fix despite a lot of forum research. I'll never try an AMD with Linux again.
