Earlier quoted context omitted.
I have a hard time believing that most purchasers of high-end consumer CPUs wouldn't use a discrete GPU. What's the use-case you're envisioning where an integrated GPU is a good use of die space?
It's mostly that there isn't a cheap discrete GPU worth buying. So if you're doing a software development rig, where yes those 12 or 16 cores will be put to good use, you're stuck with spending $100+ on a new GPU that'll spend its entire life idling or scrounging the used markets. The low-end discretes are crap rebranded from 5+ years ago. Which means outdated display connections and bad hardware video decoders.
a geforce 1030 will be adequately taxed on desktop loads: https://www.techpowerup.com/gpu-specs/geforce-gt-1030.c2954
Can get them for 40eur, they barely do 1080p.
