- Intel makes in a few weeks as much as AMD in the whole year
- AMD doesn't own fabs and can't saturate market (as seen with 39XXx shortages)
Intel owns fabs and has been having shortages for most of the year. AMD spinning out fabs seems to have been a good choice for them, as GlobalFoundry, their spun out fab, ran into problems with process shrinking and AMD was able to move Zen to another fab that got their shrink to work.
I'm not saying Intel should spin out their fabs, I'm just saying not owning your own fabs has some advantages sometimes. Owning your own fabs also has some advantages sometimes; it's certainly been a historic advantage for Intel.
Also, AMD is going to have to keep up the momentum for a while before they can make in-ways in the enterprise market.
Not to mention, it's hard to get the top SKUs from both AMD and Intel, but something that costs 85% of Intel consumer parts and has 110% of the performance is readily available.
