Intels failure in the mobile market was an attempt in the futile. The general idea was to cement Intels position because compiling for multiple platforms is a pain in the duckuss and you only code for one (usually) In this case it's Intel or ARM based solutions. (Although MIPS is still hanging on, not in the mobile market) As Intel saw that everyone was moving to mobile devices, that threatened their long term dominance. Competing on the ARM level would mean low margins and marginalization in the marketplace full of ARM competitors. Hence Intel tried the "Give it to them for free and then make them addicted" approach for Atom for Android.
The problem being even with Intel's advanced process nodes, Atom was a power hog. CISC overhead dealing with memory addressing was a disaster of legacy support for low powered systems. It just had too many transistors causing it to loose in the efficiency/watt. And Intel spent I don't know how much money just rewriting the android OS to support it.
Add to this a number of Atom chips that had the memory interface degradation issues that caused them to burn out. This made Intel lose a fortune.
Intels problem is they want high margins. They are trying to protect stock price. And this has caused Intel to paint themselves into a corner where they are desperately trying to figure out how to deal with mind-share to stay relevant. They are getting attacked on all traditional strongholds. (Consumer desktop (AMD), HEDT (AMD), Mobile (ARM), Servers (AMD Epyc & NVIDIA AI & Amazon & Google. All these companies are making competing chips which deliver better value))
The whole reason Intel likely got into the 5G modem business is because there wasn't much in terms of a competitive landscape and they saw fat potential margins with Apple given the dispute. They said the 5G will live on for other markets (ie: Wireless cards for laptops). And I think this is a viable plan. They will continue to lose money, but the competitive landscape for 5G SOC modems is still small. What will bite intel in the tail is their limited 10nm production capability. Do they support low powered mobile first? Or do they push the 5G SOC modem biz? If there's a reasonable 10nm successor to Gimini Lake anytime soon will be a huge shock and surprise.
If I were Intel I would start supporting 5G tower infrastructure including hardware to handle the data increases. That way they could have a claim of End to End Support. And the 5G infrastructure market will be huge. (Even if divided up)
The cutback on the SOC 5G Modem is another example where Intel is ditching funding on another division where they could make inroads, but at great cost. They have killed so many potential products. I guess they are looking at their Atom initiative for mobile and are afraid of losing more money. But at this point, do they have an option with declining market-share?
I don't even think Intel would be pushing graphics so hard (very low margin) if it weren't for the fact that I think APU's and Data centers will deliver much better value than Intel's offerings in a few years because of the lack of MIMD/Matrix operation raw GFLOP throughput. These operations are critical for not only games, but AI as well.
If I did individual stocks, I would short Intel over the next 5 years. I might even short NVIDIA. AMD is in a great position in the next couple of years in terms of APU and AI performance based on a combined ecosystem (Synergy) of APU + CPU/GPU. NVIDIA doesn't have much in terms of CPU performance. NVIDIA is offering a "Me too" ARM processor. Intel is playing catch up on graphics.
