Kusagadzikana kunogona kuita kuti AMD processors iwedzere kugadzira kupfuura anokwikwidza machipisi

Kuburitswa kuchangobva kuitika kweimwe njodzi muIntel processors, inodaidzwa kuti MDS (kana Zombieload), yakashanda sechipo chekuwedzera kwegakava pamusoro pehuwandu hwevashandisi vekusvibisa maitiro vachafanira kutsungirira kana vachida kutora mukana wezvakarongwa zvigadziriso. Hardware matambudziko. Intel yakaburitsa yayo performance tests, iyo yakaratidza kushoma kwekuita maitiro kubva kune zvigadziriso kunyangwe Hyper-Threading yakaremara. Zvisinei, havasi vose vanobvumirana nechinzvimbo ichi. Iyo Phoronix webhusaiti yakabata yayo yakazvimirira kudzidza matambudziko muLinux, uye yakaona kuti kuisa zvigadziriso zveseti yese yekusagadzikana kwe processor yakaonekwa nguva pfupi yadarika inotungamira kudzikira kwekuita kweIntel processors neavhareji ye16% pasina kudzima Hyper-Threading uye ne25% nayo yakaremara. Panguva imwecheteyo, kuita kwe AMD processors neZen + architecture, sezvakaratidzwa nemiedzo yakafanana, inoderera ne3% chete.

Kubva pamiyedzo yakapihwa muchidzidzo, tinogona kugumisa kuti kuderedzwa kwekuita kweIntel processors kunosiyana zvakanyanya kubva kune application kuenda kune application uye, kana Hyper-Threading yakadzimwa, inogona kudarika kana imwe nehafu saizi. Chaizvoizvo, izvi ndizvo chaizvo zvatiri kutaura nezvazvo anoti Apple, painodudza mutengo wayo wekubvisa Zombieload - kusvika ku40%. Panguva imwecheteyo, Apple, seGoogle, inotaura kuti iyi ndiyo nzira chete yekuita masisitimu akavakirwa paIntel processors akachengeteka zvachose. Kana ukasadzima Hyper-Threading, kuderera kwekuita kunogonawo kuoneka: mune yakaipisisa, inosvika kaviri saizi.

Izvo zvinofanirwa kujekeswa kuti bvunzo dzePhoronix dzaive nehanya nekutarisa mhedzisiro yeseti yese yezvigamba zvinopesana nenjodzi dzese dzichangoburwa - Specter, Meltdown, L1TF uye MDS. Uye izvi zvinoreva kuti mune iyi kesi tiri kutaura nezve musiyano mukuru mukuita uyo varidzi veIntel processors vanogashira mushure mekushandisa mapeche ese kamwechete. Izvi zvinotsanangurawo kudzikira kwekuita kwakaonekwa mu AMD processors. Kunyangwe MDS isingavakanganisa, AMD machipi anotapukirwa kune mamwe marudzi eSpecter kusasimba uye nekudaro anodawo zvigamba zvesoftware. Nekudaro, ivo havadi chero akasimba matanho akadai sekuremadza Hyper-Threading.

Kudzikira kwakanyanya mukuita kweIntel processors mushure mekushandisa zvigamba kunogona kuve chinhu chinouraya pachinzvimbo chekambani mumusika weseva. Ipo AMD iri kugadzirira kusimudza bhara rekuita neayo matsva 7nm EPYC (Rome) processor, Intel's chip performance iri kufamba zvishoma nezvishoma yakatarisana. Panguva imwecheteyo, hazvibviri kuramba kugadzirisa kusagadzikana mune server mhinduro - ndiko kwavanoisa njodzi huru. Nekudaro, AMD ine mukana wekukasika kuve mupi wekukurumidza sevha mhinduro, izvo zvichave nekukanganisa kwakakomba pachinzvimbo chayo mumusika weseva, umo kambani inovavarira kuwana chikamu chegumi muzana mugore rinotevera.

Vashandisi vevatengi vedesktop masisitimu vanogona kuramba kushandisa zvigamba, zvirinani kudzamara zvingangove zvine njodzi zvekushandisa zvisina kunaka zvaonekwa. Nekudaro, zvinoenderana nePhoronix bvunzo, nepo yekutanga Core i7-8700K ichikurumidza kupfuura iyo Ryzen 7 2700X neavhareji ye24%, mushure mekushandisa zvigadziriso mukana unoderedzwa kusvika 7%. Kana iwe ukatevedzera zvinonyanya kuchengetedza kurudziro uye, nekuwedzera, dzima Hyper-Threading, ipapo iyo yekare AMD processor ichakurumidza kupfuura iyo Core i7-8700K ne4%.
