Ukubhengezwa kwamva nje kobunye ubuthathaka kwi-Intel processors, ebizwa ngokuba yi-MDS (okanye iZombieload), isebenze njengenkuthazo yolunye ulwando lwengxoxo malunga nokuba bangakanani na abasebenzisi bokuthotywa komgangatho wokusebenza ekuya kufuneka banyamezele ukuba bafuna ukuthatha ithuba lolungiso olucetywayo. iingxaki zehardware. I-Intel ipapashe eyayo , ebonise impembelelo encinci kakhulu yokusebenza ukusuka kwizilungiso naxa i-Hyper-Threading ivaliwe. Noko ke, asingabo bonke abavumelanayo nesi sigqibo. Iwebhusayithi yePhoronix yazibambela ngokwayo iingxaki kwi-Linux, kwaye yafumanisa ukuba ukusetyenziswa kokulungiswa kweseti yonke yobuthathaka beprosesa echongiweyo kutshanje ikhokelela ekunciphiseni kwentsebenzo ye-Intel processors nge-avareji ye-16% ngaphandle kokukhubaza i-Hyper-Threading kunye ne-25% nayo ikhubazekile. Ngelo xesha, ukusebenza kweeprosesa ze-AMD nge-architecture ye-Zen +, njengoko kuboniswe ngovavanyo olufanayo, kuncipha kuphela nge-3%.
Ukusuka kwiimvavanyo ezinikezelwe kwisifundo, sinokugqiba ukuba ukuthotywa kwentsebenzo ye-Intel processors kuyahluka kakhulu ukusuka kwisicelo ukuya kwisicelo kwaye, xa i-Hyper-Threading ikhutshaziwe, inokugqithisa ngokulula kunye nesiqingatha sobukhulu. Ngenene, yile nto kanye sithetha ngayo I-Apple, xa ibiza ixabiso layo lokuphelisa i-Zombieload - ukuya kuthi ga kwi-40%. Ngelo xesha, i-Apple, njengeGoogle, ithi le kuphela kwendlela yokwenza iinkqubo ezisekelwe kwi-Intel processors zikhuselekile ngokupheleleyo. Ukuba awuyicimi i-Hyper-Threading, ukuhla kwentsebenzo kunokubonakala kakhulu: kwimeko embi kakhulu, ifikelela ngokuphindwe kabini ubukhulu.
Kufuneka kucaciswe ukuba iimvavanyo zePhoronix zijongene nokujonga umphumo wesethi yonke yeepetshi ezichasene nazo zonke izithintelo zamva nje - i-Specter, i-Meltdown, i-L1TF kunye ne-MDS. Kwaye oku kuthetha ukuba kule meko sithetha ngomahluko omkhulu ekusebenzeni abanini be-Intel processors abaya kufumana emva kokufaka zonke iipetshi ngaxeshanye. Oku kukwachaza ukuhla kwentsebenzo efunyenwe kwiiprosesa ze-AMD. Nangona i-MDS ingabachaphazeli, iitshiphusi ze-AMD zisesichengeni sohlobo oluthile lobuthathaka beSpecter kwaye ke zifuna iipetshi zesoftware. Nangona kunjalo, abafuni nawaphi na amanyathelo angqongqo njengokukhubaza i-Hyper-Threading.
Ukuwohloka okunzulu ekusebenzeni kweeprosesa ze-Intel emva kokufaka iipetshi kunokuba yinto ebulalayo kwisikhundla senkampani kwimarike yeseva. Ngelixa i-AMD ilungiselela ukuphakamisa ibha yokusebenza kunye neeprosesa zayo ezintsha ze-7nm EPYC (eRoma), ukusebenza kwe-Intel chip kuhamba ngokuthe ngcembe kwicala elichaseneyo. Ngexesha elifanayo, akunakwenzeka ukwala ukulungisa ubuthathaka kwizisombululo zeseva - kulapho zibeka ingozi enkulu. Ngaloo ndlela, i-AMD inethuba lokukhawuleza ibe ngumthengisi wezisombululo zeseva ezikhawulezayo, eziza kuba nefuthe elibi kwindawo yayo kwimarike yomncedisi, apho inkampani ijolise ekufumaneni isabelo se-10 ekhulwini kunyaka ozayo.
Abasebenzisi benkqubo yedesktophu yabathengi banokusala ukusebenzisa iipetshi, ubuncinci de kuchongwe iimeko zoxhatshazo olunokuba nobungozi bobuthathaka. Nangona kunjalo, ngokweemvavanyo zePhoronix, ngelixa i-Core i7-8700K yasekuqaleni ikhawuleza kune-Ryzen 7 2700X nge-avareji ye-24%, emva kokufaka izilungiso inzuzo iyancipha ukuya kwi-7%. Ukuba ulandela ezona ngcebiso zolondolozo kwaye, ukongeza, khubaza i-Hyper-Threading, ke iprosesa ye-AMD endala iya kukhawuleza kune-Core i7-8700K nge-4%.
