I think that he’ll be focussed on Arm because when Intel uses the phrase SoC internally they are referring to Arm, and they use the term to make a distinction with x86.
That's an increasingly archaic distinction; especially inside of the Intel client platform division. Maybe that persists in the server group, but the laptop solutions are primarily SoCs.
At this point Intel has put Thunderbolt inside of the "CPU" package. Ethernet.. on the CPU paciage. Wifi ... base unit ... on the CPU package.
Going to "CPU" packages with tiled/chiplet implementations that is likely to get even more integrated in 2-3 generations down the road.
If go back to Intel even 5-6 this wasn't the case. When Intel was selling lots more discrete chip bundles to customers that was a distinction. When there were viable 3rd party chipset vendors even more. But in 2020+ that is a "terminology" that is just lost in significant distinction.
AMD desktop Ryzen solutions are GPU less. Pragmatically all of Intel's client desktop and laptop solutions have iGPUs. iGPUs always present is in the SoC-zone.
Picking someone who was in charge of the Mac transition I suspect has little to do with ARM instruction set and more so about putting together better SoC package combos. Which set of technology implementation tiles does Intel integrate into a product groupings ?
x86_64 certainly could do with a dump of the constipation (more than complexity) there is present. Old dead ends from the 1990's . What do they toss and what do they keep would be more helping than doing an ARM "swap out" . That is in part what go 'sorted' in the Mac transition process. Some stuff got dumped on the transition.
For the client platform group .... most of what they sell is Laptops "CPU" . The whole high skew to super modularity on the desktop isn't the driving force for that division anymore. As CTO of division that is the 'ball' needs to be primarily focused on.
The server platfrom division may not weave GPUs into the "CPU" package , but there are probably specific accelerators that will be "tiled' into a broader range of server "CPU" packages in the generations 2-3 iterations out.
Servers tend to have more variable I/O components attached so harder to all the possible combos on a single 'chip' package, but it isn't going to be immune to the SoC effect of the CPU packages subsuming some stuff off the standard server logic board over time.
One of INtel's problems is that they try to build everything for everybody. That probably isn't tractable going forward. Not shrinking down to the overly narrow product line that Apple pursues, but Intel needs to get better at choosing where to apply more focus and which edge cases aren't worth doing solely internally.
