Kuwululidwa kwaposachedwa kwa chiwopsezo china mu ma processor a Intel, otchedwa MDS (kapena Zombieload), kwathandizira kukwera kwina kwa mkangano wokhudza kuchuluka kwa magwiridwe antchito omwe akuyenera kupirira ngati akufuna kupezerapo mwayi pazokonzekera zomwe zakonzedwa. mavuto hardware. Intel yatulutsa zake , zomwe zinawonetsa kuchepa kwa magwiridwe antchito kuchokera pazokonza ngakhale Hyper-Threading idayimitsidwa. Komabe, si onse amene amavomereza maganizo amenewa. Webusaiti ya Phoronix idadziyimira yokha mavuto mu Linux, ndipo adapeza kuti kugwiritsa ntchito kukonza kwa zovuta zonse za purosesa zomwe zadziwika posachedwa kumabweretsa kuchepa kwa magwiridwe antchito a Intel processors pafupifupi 16% popanda kuletsa Hyper-Threading ndi 25% ndi olumala. Nthawi yomweyo, magwiridwe antchito a mapurosesa a AMD okhala ndi zomanga za Zen +, monga zikuwonetsedwa ndi mayeso omwewo, amachepetsa ndi 3% yokha.
Kuchokera pamayesero omwe aperekedwa mu phunziroli, titha kunena kuti kuwonongeka kwa ma processor a Intel kumasiyana kwambiri kuchokera ku ntchito kupita ku ntchito ndipo, Hyper-Threading ikayimitsidwa, imatha kupitilira kukula kamodzi ndi theka. Kwenikweni, izi ndi zomwe tikukamba Apple, ikatchula mtengo wake wochotsa Zombieload - mpaka 40%. Panthawi imodzimodziyo, Apple, monga Google, imati iyi ndi njira yokhayo yopangira machitidwe opangidwa ndi Intel processors kukhala otetezeka kwathunthu. Ngati simukuzimitsa Hyper-Threading, kuchepa kwa magwiridwe antchito kumatha kuwonekeranso: zikavuta kwambiri, zimafika kuwirikiza kawiri kukula kwake.
Ziyenera kumveka bwino kuti mayeso a Phoronix anali okhudzidwa ndikuwona zotsatira za seti yonse ya zigamba motsutsana ndi zovuta zonse zaposachedwa - Specter, Meltdown, L1TF ndi MDS. Ndipo izi zikutanthauza kuti pamenepa tikukamba za kusiyana kwakukulu kwa machitidwe omwe eni ake a Intel processors adzalandira atatha kugwiritsa ntchito zigamba zonse mwakamodzi. Izi zikufotokozeranso kuchepa kwa magwiridwe antchito omwe apezeka mu ma processor a AMD. Ngakhale MDS simawakhudza, tchipisi ta AMD titha kukhala pachiwopsezo chamtundu wina wa Specter motero amafunikiranso zigamba zamapulogalamu. Komabe, safuna kuchitapo kanthu mwamphamvu monga kuletsa Hyper-Threading.
Kuwonongeka kwakukulu kwa magwiridwe antchito a ma processor a Intel atagwiritsa ntchito zigamba zitha kukhala vuto lalikulu pamakampani pamsika wa seva. Pomwe AMD ikukonzekera kukweza kapamwamba kantchito ndi mapurosesa ake atsopano a 7nm EPYC (Rome), Intel's chip performance ikupita kwina. Panthawi imodzimodziyo, sikutheka kukana kukonza zowonongeka muzothetsera za seva - ndipamene amaika chiopsezo chachikulu. Choncho, AMD ili ndi mwayi woti posachedwa ikhale yopereka mayankho a seva mofulumira, zomwe zidzakhudza kwambiri malo ake pamsika wa seva, momwe kampaniyo ikufuna kupeza gawo la 10 peresenti chaka chamawa.
Ogwiritsa ntchito makina apakompyuta ogula atha kukana kugwiritsa ntchito zigamba, mpaka pomwe zidziwitso zowopsa zazachiwopsezo zitadziwika. Komabe, molingana ndi mayeso a Phoronix, pomwe Core i7-8700K yoyambirira imathamanga kuposa Ryzen 7 2700X pafupifupi 24%, mutagwiritsa ntchito zokonza mwayi umachepetsedwa mpaka 7%. Ngati mutsatira malangizo osamala kwambiri, komanso, kuletsa Hyper-Threading, ndiye kuti purosesa yakale ya AMD idzakhala yachangu kuposa Core i7-8700K ndi 4%.
