Ama-Intel processors aqukethe iphutha elikhulu lezokuphepha, ukulungiswa okuzokwenza ukuthi amakhompyutha ehlise ijubane

Izolo ebusuku, kuvele umyalezo obucayi kakhulu kuwebhu wokuthi ama-Intel processors anephutha elisanda kutholwa lezokuphepha. Lokhu kuyinkinga engathi sína ngoba kuyiphutha elibangelwa ukwakheka kwesakhiwo ngokwaso. Ngaphezu kwalokho, leli phutha livela kuwo wonke ama-Intel processors esimanje ngakho-ke aqinisekiswa ngokuyisisekelo ukuthi azothinta okungenani wonke amamodeli avela emndenini we-Core iX. Lokhu kuvele emashalofini esitolo ngo-2008. Lokhu kushiyeka kwezokuphepha kudinga isiqeshana esisezingeni lesistimu yokusebenza, kodwa lokhu kuzobangela ikhompuyutha ngokwayo ukuthi ihambe kancane.

Lolu lwazi luvele izolo, futhi kusukela ngaleso sikhathi kwethulwe inqwaba yokuqagela nolwazi olunganembile, olungakapheli. Kuze kube manje, kusobala kuphela ukuthi le nkinga ithinta wonke amaphrosesa anamuhla avela ku-Intel, futhi ukulungisa le nkinga kuzodinga isibuyekezo sesistimu yokusebenza efanele, kungaba yiWindows, macOS noma iLinux. Isiphazamisi sisekuklanyweni kwesakhiwo se-x86 futhi uguquko olulula ku-microcode ngeke lusize.

Ulwazi olufanele mayelana naleli cala alusizwa ukuthi lonke uphenyo lugubuzelwe wukuvinjelwa kolwazi oluzosebenza kuze kube sekupheleni kukaJanuwari. Ngokolwazi olutholakalayo, inkinga ukuthi lesi siphazamisi sivumela izinhlelo ukuthi zifinyelele esigabeni esivikelwe sememori ye-kernel ngokuvamile ebezingeke zikwazi ukuyifinyelela. Izinhlelo eziyingozi zingangena kule nkumbulo futhi zifunde ekuqukethe. Isibonelo, amaphasiwedi, idatha yokungena, ulwazi mayelana namafayela noma izitifiketi ezihlukahlukene, njll. kungatholakala lapha.

Icala elibi kakhulu: 23%

Kuze kube manje, kubukeka sengathi lesi isiphazamisi esibi ngempela uma kubhekwa ukuthi abathuthukisi beWindows neLinux basabela kanjani kuso - ukulungisa sekuvele kunzima emsebenzini. Ukuze ulungise leli phutha, ingxenye yenkumbulo ye-kernel idinga ukuhlukaniswa kabusha nezinqubo ezizungezile. Nokho, lesi senzo sizobangela ikhompuyutha ukuthi yehlise ijubane phakathi kuka-5 no-30%. Okwamanje akukacaci ngokuphelele ukuthi lolu daba luzodlalwa kanjani endaweni yesikhulumi se-macOS. Nokho, singalindela ukuthi umthelela ufane nezinye izinkundla. Ukulungisa sekuvele kunzima emsebenzini, njengoba sekushicilelwe izikhathi eziningana yimithombo ehlukahlukene. Ulwazi olwengeziwe luzovela ngemva kokuphela kwe-embargo, esikhathini esithile engxenyeni yesibili kaJanuwari. Ungathola ulwazi olwengeziwe (ngesiNgisi). lapha.

Phew, AMD :)

Kuze kube manje, akubukeki njengokuthi "Ugh, AMD". Ngokwemibiko yakuqala, i-AMD yehlulekile ukukholisa abathuthukisi abafanelekile ukuthi bagcine amasistimu anama-AMD processors kusuka kulesi sibuyekezo se-OS.
