Den seneste afsl\u00f8ring af en ny s\u00e5rbarhed i Intel-processorer, kaldet MDS (eller Zombieload), har givet anledning til en ny ophedet debat om, hvilken ydelsesnedgang brugerne m\u00e5 forholde sig til, hvis de \u00f8nsker at benytte de foresl\u00e5ede rettelser til hardwareproblemerne. Intel har offentliggjort sine egne ydelsestests<\/a><\/noindex>, som viser en ekstremt lille indvirkning fra rettelserne p\u00e5 hastigheden, selv n\u00e5r Hyper-Threading teknologien er deaktiveret. Dog er der ikke enighed om denne holdning. Phoronix hjemmeside gennemf\u00f8rte en uafh\u00e6ngig forskning<\/a><\/noindex> Problemer i Linux har vist, at anvendelse af rettelser til det nyligt opdagede s\u00e6t af processorfejl resulterer i et gennemsnitligt pr\u00e6stationsfald p\u00e5 16 % for Intel-processorer uden at sl\u00e5 Hyper-Threading fra, og 25 % med det sl\u00e5et fra. Samtidig viser disse tests, at pr\u00e6stationen af AMD's Zen+-arkitektur-processorer kun falder med 3 %.<\/p>\n

\"S\u00e5rbarheder<\/p>\n

Ud fra de pr\u00e6senterede testresultater kan det konkluderes, at ydelsesnedgangen for Intel-processorer varierer meget fra applikation til applikation og kan let overstige 1,5 gange, n\u00e5r Hyper-Threading er deaktiveret. Det er netop dette says<\/a><\/noindex> Apple omtaler prisen for at fjerne Zombieload som op til 40 %. Apple, ligesom Google, p\u00e5peger, at systemer baseret p\u00e5 Intel-processorer kun kan g\u00f8res helt sikre p\u00e5 denne m\u00e5de. Hvis Hyper-Threading ikke sl\u00e5s fra, kan pr\u00e6stationsfaldet dog ogs\u00e5 v\u00e6re meget m\u00e6rkbart: i v\u00e6rste fald opn\u00e5r det en dobbelt st\u00f8rrelse.<\/p>\n

\"S\u00e5rbarheder<\/p>\n

Det skal understreges, at Phoronix' tests omhandlede unders\u00f8gelsen af indflydelsen af alle de nyligt offentliggjorte sikkerhedsopdateringer mod de seneste s\u00e5rbarheder \u2013 Spectre, Meltdown, L1TF og MDS. Det betyder, at der er tale om den maksimale forskel i pr\u00e6station, som ejere af Intel-processorer f\u00e5r efter at have anvendt alle patchene. Det forklarer ogs\u00e5 det pr\u00e6stationsfald, der er registreret for AMD-processorer. Selvom MDS ikke p\u00e5virker dem, er AMD-chips udsat for visse typer af Spectre-s\u00e5rbarhed, hvilket ogs\u00e5 kr\u00e6ver installation af softwarerettelser. Der er dog ikke behov for nogen drastiske foranstaltninger som at sl\u00e5 Hyper-Threading fra for dem.<\/p>\n

Det alvorlige pr\u00e6stationsfald for Intel-processorer efter anvendelsen af patchene kan blive en fatal faktor for virksomhedens position p\u00e5 servermarkedet. Mens AMD er ved at h\u00e6ve standarden for ydeevne med sine nye 7-nm EPYC (Rome) processorer, bev\u00e6ger pr\u00e6stationen for Intel-chips sig sikkert i den stik modsatte retning. At undlade at rette s\u00e5rbarheder i serverl\u00f8sninger er dog umuligt \u2013 der udg\u00f8r de netop den st\u00f8rste fare. Dermed har AMD en chance for snart at blive leverand\u00f8r af hurtigere serverl\u00f8sninger, hvilket vil have en betydelig indvirkning p\u00e5 virksomhedens position p\u00e5 servermarkedet, hvor den planl\u00e6gger at generobre en 10 procent andel over det n\u00e6ste \u00e5r.<\/p>\n

\n\"S\u00e5rbarheder<\/p>\n

Brugere af forbruger-niveau desktop-systemer kan ganske vist v\u00e6lge at undg\u00e5 at anvende patches, i det mindste indtil der identificeres potentielt farlige udnyttelsesscenarier for deres s\u00e5rbarheder. Ikke desto mindre viser tests fra Phoronix, at hvis en Core i7-8700K i sin oprindelige tilstand er hurtigere end en Ryzen 7 2700X med gennemsnitligt 24 %, s\u00e5 reduceres fordelen til 7 % efter anvendelse af rettelserne. Hvis man f\u00f8lger de mest konservative anbefalinger og desuden deaktiverer Hyper-Threading, vil den \u00e6ldre AMD-processor v\u00e6re hurtigere end Core i7-8700K med 4 %.<\/p>\n
