A Phoronix weboldal f\u00fcggetlen kutat\u00e1s<\/a><\/noindex> Linux probl\u00e9m\u00e1i, \u00e9s kider\u00fclt, hogy a legut\u00f3bbi id\u0151szakban felfedezett tranzitorszerkezetek teljes k\u00f6r\u0171 jav\u00edt\u00e1s\u00e1nak alkalmaz\u00e1sa az Intel processzorok teljes\u00edtm\u00e9ny\u00e9t \u00e1tlagosan 16%-kal cs\u00f6kkenti, ha a Hyper-Threading ki van kapcsolva, \u00e9s 25%-kal, ha be van kapcsolva. Ezzel szemben az AMD Zen+ architekt\u00far\u00e1j\u00fa processzorainak teljes\u00edtm\u00e9nye ezen tesztek szerint csup\u00e1n 3%-kal cs\u00f6kken.<\/p>\n

A kutat\u00e1sban bemutatott tesztekb\u0151l arra lehet k\u00f6vetkeztetni, hogy az Intel processzorok teljes\u00edtm\u00e9nycs\u00f6kken\u00e9se er\u0151sen elt\u00e9r az alkalmaz\u00e1sok k\u00f6z\u00f6tt, \u00e9s a Hyper-Threading kikapcsol\u00e1sakor k\u00f6nnyen meghaladhatja m\u00e1sf\u00e9l szeres \u00e9rt\u00e9ket. \u00c9ppen err\u0151l mondja<\/a><\/noindex> Az Apple c\u00e9g, amikor a Zombieload elt\u00fcntet\u00e9s\u00e9nek \u00e1r\u00e1t eml\u00edti, ak\u00e1r 40%-ot is mond. Az Apple, mint ahogy a Google is, azt \u00e1ll\u00edtja, hogy az Intel processzorok alap\u00fa rendszereket csak \u00edgy lehet teljesen biztons\u00e1goss\u00e1 tenni. Ha viszont nem kapcsolj\u00e1k ki a Hyper-Threadinget, a teljes\u00edtm\u00e9nycs\u00f6kken\u00e9s is meglehet\u0151sen \u00e9szlelhet\u0151 lehet: a legrosszabb esetben ak\u00e1r megdupl\u00e1z\u00f3dik.<\/p>\n

Fontos tiszt\u00e1zni, hogy a Phoronix tesztek a legut\u00f3bbi id\u0151szakban felfedezett sebezhet\u0151s\u00e9gekre vonatkoz\u00f3 \u00f6sszes jav\u00edt\u00e1s hat\u00e1s\u00e1t vizsg\u00e1lt\u00e1k, mint p\u00e9ld\u00e1ul a Spectre, Meltdown, L1TF \u00e9s MDS. Ez azt jelenti, hogy ebben az esetben a legnagyobb teljes\u00edtm\u00e9nyk\u00fcl\u00f6nbs\u00e9gr\u0151l van sz\u00f3, amelyet az Intel processzorok tulajdonosai tapasztalnak, ha az \u00f6sszes jav\u00edt\u00e1st egyszerre alkalmazz\u00e1k. Ez magyar\u00e1zza az AMD processzorok eset\u00e9ben tapasztalt teljes\u00edtm\u00e9nycs\u00f6kken\u00e9st is. B\u00e1r az MDS nem \u00e9rinti \u0151ket, az AMD chipek bizonyos t\u00edpus\u00fa Spectre sebezhet\u0151s\u00e9geknek vannak kit\u00e9ve, ez\u00e9rt programjav\u00edt\u00e1sokat is ig\u00e9nyelnek. Azonban olyan radik\u00e1lis int\u00e9zked\u00e9sekre, mint a Hyper-Threading kikapcsol\u00e1sa, nincs sz\u00fcks\u00e9g.<\/p>\n

Az Intel processzorok teljes\u00edtm\u00e9ny\u00e9nek jelent\u0151s cs\u00f6kken\u00e9se a jav\u00edt\u00e1sok alkalmaz\u00e1sa ut\u00e1n d\u00f6nt\u0151 t\u00e9nyez\u0151v\u00e9 v\u00e1lhat a c\u00e9g helyzet\u00e9ben a szerverpiacon. Mik\u00f6zben az AMD k\u00e9szen \u00e1ll arra, hogy \u00faj 7 nm-es EPYC (Rome) processzoraival felemelje a teljes\u00edtm\u00e9ny szintj\u00e9t, az Intel chipek teljes\u00edtm\u00e9nye biztosan az ellenkez\u0151 ir\u00e1nyba halad. Ugyanakkor a sebezhet\u0151s\u00e9gek jav\u00edt\u00e1sa a szervermegold\u00e1sokban elker\u00fclhetetlen, mivel ezek jelentik a legf\u0151bb vesz\u00e9lyt. \u00cdgy az AMD es\u00e9lyt kap arra, hogy hamarosan gyorsabb szervermegold\u00e1sok sz\u00e1ll\u00edt\u00f3j\u00e1v\u00e1 v\u00e1ljon, ami komoly hat\u00e1ssal lesz a szerverpiaci helyzet\u00e9re, ahol a c\u00e9g a k\u00f6vetkez\u0151 \u00e9vben 10%-os r\u00e9szesed\u00e9st k\u00edv\u00e1n megszerezni.<\/p>\n

A fogyaszt\u00f3i szint\u0171 asztali rendszerek felhaszn\u00e1l\u00f3i elvileg lemondhatnak a jav\u00edt\u00e1sok alkalmaz\u00e1s\u00e1r\u00f3l, legal\u00e1bbis addig, am\u00edg a sebezhet\u0151s\u00e9gek potenci\u00e1lisan vesz\u00e9lyes kihaszn\u00e1l\u00e1si szcen\u00e1ri\u00f3i fel nem mer\u00fclnek. Ennek ellen\u00e9re a Phoronix tesztjei szerint, ha az alap\u00e1llapotban a Core i7-8700K 24%-kal gyorsabb, mint a Ryzen 7 2700X, akkor a jav\u00edt\u00e1sok alkalmaz\u00e1sa ut\u00e1n az el\u0151ny 7%-ra cs\u00f6kken. Ha pedig k\u00f6veti a legkonzervat\u00edvabb aj\u00e1nl\u00e1sokat \u00e9s letiltja a Hyper-Threading-et, akkor az AMD cs\u00facsprocesszora 4%-kal gyorsabb lesz, mint a Core i7-8700K.<\/p>\n
