архитектура компьютера — нет, процессора не совсем, то что внутри — структурой называют
In computer engineering, microarchitecture, also called computer organization and sometimes abbreviated as µarch or uarch, is the way a given instruction set architecture (ISA) is implemented in a particular processor.[1] A given ISA may be implemented with different microarchitectures;[2][3] implementations may vary due to different goals of a given design or due to shifts in technology.[4]
