Juba rohkem kui aasta p\u00e4rast avastusi Spectre ja Meltdown on protsessorite turg pidevas h\u00e4das, kuna avastatakse \u00fcha uusi ja uusi haavatavusi, mis on seotud spekulatiivsete arvutustega. K\u00f5ige enam kannatavad nende all, sealhulgas<\/a><\/noindex> viimane<\/a><\/noindex> ZombieLoad<\/a><\/noindex>, on Intel'i kiibid. Muidugi, AMD kasutas sellest v\u00f5imalust, r\u00f5hutades oma protsessorite turvalisust.<\/p>\n

\"AMD<\/p>\n

Pealehe lehe<\/noindex>, mis Spectre-sarnaste haavatavustega, teatas ettev\u00f5te uhkelt: «Me AMD-s arendame oma tooteid ja teenuseid turvalisuse n\u00f5udeid silmas pidades. Tuginedes tehtud sisemisele anal\u00fc\u00fcsile ja aruteludele turvauuringute eksperdiga, usume, et meie tooted pole r\u00fcnnakutele vastuv\u00f5tlikud Fallout, RIDL<\/a><\/noindex> v\u00f5i ZombieLoad<\/a><\/noindex> . T\u00e4nu meie arhitektuuris olevate riistvarakaitse kontrollide olemasolule ei suutnud me neid haavatavusi AMD toodetes uuesti luua ega ole andmeid selle kohta, et keegi teine oleks suutnud seda saavutada». Teated \u00fctlevad, et AMD protsessorid on vastupidavad ka veel \u00fche r\u00fcnnaku MDS<\/a><\/noindex> \u2014 Store-to-Leak Forwarding<\/a><\/noindex>.<\/p>\n

Uute haavatavuste avastamise ja tootjate vajaduse t\u00f5ttu nende vastu vastavaid plaastreid paigaldada v\u00f5ivad AMD protsessorid osutuda konkurendi lahendustest tootlikumaks vastavalt hiljutisele iseseisvale uurimusele<\/a><\/noindex>, mille viis l\u00e4bi Phoronix, toob k\u00f5ikide tuvastatud protsessorite haavatavustega seotud paranduste rakendamine endaga kaasa Intel protsessorite keskmise j\u00f5udluse languse 16% (Hyper-Threadingu keelamisel isegi 25%). AMD Zen+ protsessorite puhul langeb j\u00f5udlus samades tingimustes vaid 3%.<\/p>\n

Kohan ka halvem: Apple ja Google alustada jaotatud versioonihaldust\u00f6\u00f6riistadega. Nendega on lihtsam hallata l\u00e4htekoodi. Selliste lahenduste seas on k\u00f5ige tuntumad Git, Mercurial, Subversion (SVN) ja CVS.<\/a><\/noindex> kuna Intel kasutajatel on soovitatav Hyper-Threading t\u00e4ielikult v\u00e4lja l\u00fclitada, mis v\u00f5ib j\u00f5udlust m\u00f5nikord v\u00e4hendada kuni 40\u201350% (s\u00f5ltuvalt \u00fclesandest). Isegi Intel soovitab seda mitte teha<\/a><\/noindex> enamikes olukordades, kuid probleem v\u00f5ib osutuda eriti kriitiliseks t\u00f6\u00f6jaamadele, serveritele ja muudele j\u00f5udluse ja turvalisuse osas tundlikele valdkondadele. AMD kiipide puhul ei ole samav\u00e4\u00e4rse Simultaneous Multi-Threading tehnoloogia v\u00e4ljal\u00fclitamine vajalik. Peale selle ei saa uudiste voog haavatavuste kohta, sealhulgas teavet Intel'i katsetest varjata teavet<\/a><\/noindex> avalikkuse eest, mitte m\u00f5jutada viimase mainet.<\/p>\n

Need on eriti kehv aeg Intelile: AMD on peagi turule toomas kaasaegsete 7-nanomeetriste CPUde seeria Zen 2 arhitektuuriga nii lauaarvutitele kui serverite jaoks. Vahepeal kasutab Intel endiselt v\u00e4ga vana (tehnoloogia arengu kontekstis) 14-nanomeetrist tehnoloogiat ja ei suuda kuidagi alustada 10-nanomeetrite kiipide tootmist. K\u00f5ik see m\u00e4ngib AMD kasuks, kes kindlasti j\u00e4tkab oma turuosa suurendamist.<\/p>\n
