Tick tock (not tik tok)
"How portable are the chips at moving to different fabs that use different processes? I don't know, but would suspect they are designed to use the processes that the target fab uses."
Certainly Intel used to like people to believe that close architecture/process co-operation worked in their favour.
"Tick tock" advances used to be a key marketing message from Intel: alternate process improvements and architecture improvements:
"A Tick Advances Manufacturing Technology
In every "tick" cycle, Intel introduced advanced manufacturing process technology to help deliver the expected benefits of Moore’s Law to users.
A Tock Delivers New Microarchitecture
In every “tock” cycle, Intel introduced manufacturing process technologies to introduce the next big innovation in processor microarchitecture. Intel® microarchitecture advancements seek to improve energy efficiency and performance as well as functionality and density of features such as hardware-supported video transcoding, encryption/decryption, and other integrated capabilities."
Tick tock was publically abandoned around 2016 when it became apparent that Intel's 10nm process wasn't what it ought to have been, see e.g.
Intel tried to continue the link by describing their new approach as "Process - Architecture - Optimisation" but sooner or later people will notice that the new products aren't available as planned.
