Ka rite ki te maha atu microprocessors x86, whakamaoritia ratou x86-whakaaro (whakaaro CISC) ki ngā mahi ā-roto māmā (i ētahi wā e kiia ana he iti-op, i.e., whai hua RISC tohutohu kāhua) i mua i te whakahaeretanga. Ko te nuinga o ngā tohutohu hua kotahi iti-op ina whakamaoritia, me te a tawhio noa 4% o ngā tohutohu whakamahia i roto i ngā hōtaka auau whakaputa maha iti-op. Ko te maha o ngā tohutohu e whakaputa i neke atu i te kotahi iti-op he nui iti iho i te P6 me te NetBurst microarchitectures. I roto i te Bonnell microarchitecture, ka taea e ngā pūtukatuka ā-op ā-roto e rua i te mahara, me te kawenga i roto i te mahara ki te mahi ALU anake, na te mea atu kaha ki te taumata x86 (CISC tohutohu) me taea ai te whakamahi i ngā kaupapa rite rite i roto i te Intel i whakamahia i mua i roto i te Bonnell. Heoi, ko te nuinga o ngā tohutohu hua kotahi iti-op ina whakamaoritia, ki te
te whakarei ake i te mahinga mo ia whatianga
