At least one analyst believes Intel should shut down or sell off its GPU division

Begrudgingly, it would be best if Intel persevere and try until at least Celeste.

But if they fail, in the industry it couldn't happen to a more deserving company. Intel are have been in need of a serious humbling for years now, and their 14nm+++++++++ wasn't anywhere near enough.

And given the attitude that they seem to be taking to department performance, even with being more relevant than most, I could see them deciding for profit reasons to think this is a loss and cut it.

Short term, if you're not seeing decent ROI in a timely manner you dump and move on. Makes perfect sense. Big problem, what's a resonable time frame? 5 years, 10, how about over 22 years, because that's how long AMD and Nvidia have been refining thier products.
I remember their first offerings and they weren't all that good, hell ATI (Became AMD after buy out) had a really bad early track record IMHO. I got so many duds from them I swore off them for years and didn't buy another until I bought a HD 4870.
So, of course you don't want to fall for the sunk cost fallacy, but you want to give it a resonable try as well. And I don't think one generation of products is even close to a decent attempt. Not if you want any chance of success.
But what do I know, I just spend way too much money on the stupid things is all...
