Ukudalulwa kwakamuva kokunye ukuba sengozini kuma-Intel processors, okubizwa nge-MDS (noma i-Zombieload), kube yisisusa sokunye ukwanda kwenkulumompikiswano mayelana nokuthi kungakanani ukucekelwa phansi komsebenzi abasebenzisi okuzodingeka bakubekezelele uma befuna ukusizakala ngokulungiswa okuhlongozwayo. izinkinga zehardware. I-Intel isishicilele eyakhe , ebonise umthelela omncane kakhulu wokusebenza kusukela ekulungisweni nalapho i-Hyper-Threading ikhutshaziwe. Nokho, akubona bonke abavumelana nalesi sikhundla. Iwebhusayithi yePhoronix ibizimele ngokwayo izinkinga ku-Linux, futhi ithole ukuthi ukusebenzisa ukulungiswa kwesethi yonke yokuba sengozini kwephrosesa okuhlonzwe kamuva nje kuholela ekwehleni kokusebenza kwama-Intel processors ngesilinganiso esingu-16% ngaphandle kokukhubaza i-Hyper-Threading futhi ngo-25% ikhutshaziwe. Ngesikhathi esifanayo, ukusebenza kwe-AMD processors nge-Architecture ye-Zen +, njengoba kuboniswa ukuhlolwa okufanayo, kwehla ngo-3% kuphela.
Kusukela ekuhlolweni okwethulwe ocwaningweni, singaphetha ngokuthi ukuwohloka kokusebenza kwama-Intel processors kuyahluka kakhulu kusukela kuhlelo lokusebenza kuya ekusetshenzisweni futhi, lapho i-Hyper-Threading ikhutshaziwe, ingadlula kalula ngisho nezikhathi eziphindwe nesigamu kunosayizi. Empeleni, yilokhu kanye esikhuluma ngakho I-Apple, uma ibiza intengo yayo yokuqeda i-Zombieload - kufika ku-40%. Ngesikhathi esifanayo, i-Apple, njenge-Google, ithi lena ukuphela kwendlela yokwenza amasistimu asekelwe ku-Intel processors aphephe ngokuphelele. Uma ungayivali i-Hyper-Threading, ukwehla kokusebenza nakho kungabonakala: esimweni esibi kakhulu, kufinyelela usayizi ophindwe kabili.
Kufanele kucaciswe ukuthi ukuhlolwa kwe-Phoronix bekuphathelene nokuhlola umphumela wayo yonke isethi yamapeshi ngokumelene nabo bonke ubungozi bamuva - i-Specter, i-Meltdown, i-L1TF ne-MDS. Futhi lokhu kusho ukuthi kuleli cala sikhuluma ngomehluko omkhulu ekusebenzeni okuzotholwa ngabanikazi be-Intel processors ngemuva kokusebenzisa wonke ama-patches ngesikhathi esisodwa. Lokhu kuphinde kuchaze ukwehla kokusebenza okutholwe kumaphrosesa e-AMD. Nakuba i-MDS ingazithinti, ama-chips e-AMD angenwa ezinye izinhlobo zobungozi be-Specter ngakho-ke adinga neziqephu zesoftware. Kodwa-ke, azidingi izinyathelo eziqinile njengokukhubaza i-Hyper-Threading.
Ukuwohloka okukhulu ekusebenzeni kwama-Intel processors ngemva kokufaka ama-patches kungaba yingozi enkulu esikhundleni senkampani emakethe yeseva. Ngenkathi i-AMD ilungiselela ukuphakamisa ibha yokusebenza ngamaphrosesa ayo amasha e-7nm EPYC (Roma), ukusebenza kwe-chip ye-Intel kuhamba kancane kuya kolunye uhlangothi. Ngesikhathi esifanayo, akunakwenzeka ukwenqaba ukulungisa ukukhubazeka kuzixazululo zeseva - yilapho bebeka khona ingozi enkulu. Ngakho-ke, i-AMD inethuba lokuthi maduzane ibe umphakeli wezixazululo zeseva ezisheshayo, okuzoba nomthelela omkhulu endaweni yayo emakethe yeseva, lapho inkampani ihlose ukuthola isabelo samaphesenti angu-10 ngonyaka ozayo.
Abasebenzisi bezinhlelo zedeskithophu yabathengi bangase banqabe ukusebenzisa amapeshi, okungenani kuze kubonakale izimo zokuxhashazwa okungaba yingozi zobungozi. Kodwa-ke, ngokusho kokuhlolwa kwePhoronix, kuyilapho i-Core i7-8700K yasekuqaleni ishesha kune-Ryzen 7 2700X ngesilinganiso esingu-24%, ngemva kokufaka izilungiso inzuzo iyancipha ibe ngu-7%. Uma ulandela izincomo eziqinile kakhulu futhi, ngaphezu kwalokho, ukhubaza i-Hyper-Threading, khona-ke iphrosesa endala ye-AMD izoshesha kune-Core i7-8700K ngo-4%.
