Mukupindura chikumbiro chakatumirwa che kernel Linux Linus Torvalds, muchikamu chinotsigira maswichi e compiler anotsanangura "version" ye x86_64 microarchitecture (level ye microarchitecture), akataura kushoropodza kwakasimba uye kwakanaka kwechirongwa ichi. Mavhezheni anotaura nezve microarchitecture state slices dzakataurwa ne AMD, Intel, Red Hat, uye SUSE, dzichifukidza mamwe ma extensions. Semuenzaniso, x86-64-v3 inoratidza kuvapo kweAVX, AVX2, BMI2, FMA, LZCNT, MOVBE, uye SXSAVE extensions, nepo x86-64-v4 ichireva AVX512F, AVX512BW, AVX512CD, AVX512DQ, uye AVX512VL.
Zvichemo zvaLinus zvinodzika kusvika pamapoinzi matatu:
- Rondedzero yataurwa haina pamutemo uye haienderane nechero chinhu.
- Iyo vhezheni sisitimu inotsiva iyo iri nyore mubvunzo "iyi processor ingaite murairo wakadaro?" pamwe nekunyanya kuoma "chii chinonzi x86_64 v3 chinomborevei uye chingaite sei?!"
- Pfungwa yekuyedza kuenzanisa CPUID uye kuiita kuti ive "shanduro" yakashoropodzwa. Izvi hazvina kubudirira zvekuti zvakatungamira kune ichangoburwa Intel desktop processors isingaite AVX-512 kuve iri pamutemo vhezheni yakaderera pane ekare processors anotsigira AVX-512, inova mamiriro asinganzwisisike.
