I really believe this lackluster launch is a direct result of the cost cutting and transformation Intel is attempting.
That seems like a stretch. It happened too recently. Whoever was managing the release would've had a schedule with the remaining work planned and would know who's on the hook for what. Employees key to that delivery wouldn't have been terminated. Also, keep in mind that the 15% workforce reduction didn't occur on the day it was announced. It unfolded in the following month or more, I think. It's not like just turning up for work and finding 1 of every 6 colleagues randomly absent.
Any who quit of their own accord would've given notice (usually 2 weeks). Their manager could've arranged time for knowledge transfer to their colleagues who were remaining.
Also, don't forget that Lunar Lake was basically the same architecture and launched a couple months earlier. That should've provided some initial experience tuning big/little scheduling, etc. Furthermore, the launch date for Arrow Lake seemed to slip a few weeks, which should've given them even more time.
Basically, if this does really explain the botched launch, then Intel already would've had to be a clown show.
