Hiljutine teave uuest Intel'i protsessorite haavatavusest, tuntud kui MDS (v\u00f5i Zombieload), on toonud esile uue arutelu selle \u00fcle, millisest j\u00f5udluse langusest peavad kasutajad loobuma, kui nad soovivad kasutada pakutavaid riistvaraprobleemide parandusi. Intel on avaldanud oma j\u00f5udlustestid<\/a><\/noindex>, mis n\u00e4itavad, et paranduste m\u00f5ju j\u00f5udlusele on \u00e4\u00e4rmiselt v\u00e4ike, isegi kui Hyper-Threading on v\u00e4lja l\u00fclitatud. Siiski ei ole k\u00f5ik sellega n\u00f5us. Portaal Phoronix teostas oma s\u00f5ltumatu uurimus<\/a><\/noindex> Linuxi probleemide k\u00e4igus on selgunud, et hiljutiste protsessorivulnerabiliteetide kompleksi parandamine p\u00f5hjustab Intel'i protsessorite keskmise j\u00f5udluse langust 16% v\u00f5rreldes Hyper-Threadingu v\u00e4ljal\u00fclitamisega ja 25% \u2014 selle v\u00e4ljal\u00fclitamisega. Samal ajal j\u00e4\u00e4b AMD Zen+ arhitektuuri protsessorite j\u00f5udlus, nagu need testid n\u00e4itavad, vaid 3% alla.<\/p>\n

\"Haavatavused<\/p>\n

Uuringu testide p\u00f5hjal v\u00f5ib j\u00e4reldada, et Intel'i protsessorite j\u00f5udluse langus varieerub oluliselt erinevate rakenduste vahel ning Hyper-Threadingi v\u00e4ljal\u00fclitamisel v\u00f5ib see kergesti \u00fcletada isegi 1,5-kordset taset. T\u00e4pselt sellest ongi juttu. \u00fctleb<\/a><\/noindex> Apple, kui see nimetab Zombieloadi k\u00f5rvaldamise hinnaks kuni 40%. Samuti \u00fctleb Apple, nagu ka Google, et Intel'i protsessoritel p\u00f5hinevate s\u00fcsteemide t\u00e4iesti turvaliseks muutmine on v\u00f5imalik ainult nii. Kui Hyper-Threadingu v\u00e4ljal\u00fclitamisele ei toetuta, v\u00f5ib j\u00f5udluse langus olla samuti \u00fcsna m\u00e4rgatav: halvemal juhul v\u00f5ib see ulatuda kahekordse suuruseni.<\/p>\n

\"Haavatavused<\/p>\n

Oluline on m\u00e4rkida, et Phoronixi testid k\u00e4sitlesid kogu plaastrite kogumi m\u00f5ju viimaste haavatavuste, nagu Spectre, Meltdown, L1TF ja MDS, korral. See t\u00e4hendab, et antud juhul r\u00e4\u00e4gitakse maksimaalsest j\u00f5udluse erinevusest, mida saavad Intel-i protsessorite omanikud, kui aktiveerida k\u00f5ik plaastrid korraga. Samuti selgitab see j\u00f5udluse langust, mis tuvastati AMD protsessorite puhul. Kuigi MDS neid ei m\u00f5juta, on AMD kiibid haavatavad teatud Spectre'i t\u00fc\u00fcpide suhtes, mist\u00f5ttu vajavad nad samuti tarkvarakorrektiive. Siiski ei ole vajalikud mingeid radikaalseid meetmeid, nagu Hyper-Threading'i v\u00e4ljal\u00fclitamine.<\/p>\n

Intel-i protsessorite j\u00f5udluse t\u00f5sine halvenemine p\u00e4rast plaastrite rakendamist v\u00f5ib osutuda ettev\u00f5tte jaoks saatuslikuks teguriks serveriturul. Samal ajal kui AMD valmistub oma uute 7-nm EPYC (Rome) protsessoritega j\u00f5udluse taset t\u00f5stma, liiguvad Intel-i kiipide tulemused kindlalt vastupidises suunas. Samuti ei saa serverilahendustes haavatavuste parandamisest loobuda \u2014 seal esindavad need just k\u00f5ige suuremat ohtu. Seega on AMD-l v\u00f5imalus varsti saada kiiremate serverilahenduste pakkujaks, mis m\u00f5jutab t\u00f5siselt tema positsiooni serveriturul, kus ettev\u00f5te plaanib j\u00e4rgmise aasta jooksul taastada 10% turuosa.<\/p>\n

\n\"Haavatavused<\/p>\n

Tavalisest lauas\u00fcsteemide kasutajad v\u00f5ivad v\u00e4hemalt kuni potentsiaalselt ohtlike haavatavuste kasutusskeemide tuvastamiseni plaanidest loobuda. Siiski on Phoronixi testide p\u00f5hjal, et kui algselt on Core i7-8700K keskmiselt 24% kiiremini kui Ryzen 7 2700X, siis p\u00e4rast paranduste rakendamist see eelis kahaneb 7%-ni. Kui aga j\u00e4rgida konservatiivsemaid soovitusi ja lisaks v\u00e4lja l\u00fclitada Hyper-Threading, siis osutub vanem AMD protsessor 4% kiiremaks kui Core i7-8700K.<\/p>\n
