Nyuam qhuav pib lub hlis no, nws tau paub txog kev tshawb pom ntawm qhov tsis txaus ntseeg tshiab hauv Intel processors, uas yog hu ua "Spoiler". Cov kws tshaj lij uas txheeb xyuas qhov teeb meem tau tshaj tawm tias AMD thiab ARM processors tsis raug rau nws. Tam sim no AMD tau lees paub tias, ua tsaug rau nws cov qauv tsim vaj tsev, Spoiler tsis ua rau muaj kev hem thawj rau nws cov txheej txheem.
Raws li nrog Spectre thiab Meltdown vulnerabilities, qhov teeb meem tshiab nyob rau hauv qhov kev siv ntawm speculative execution mechanisms nyob rau hauv Intel processors. Hauv AMD chips, cov txheej txheem no tau siv sib txawv; tshwj xeeb, kev sib txawv yog siv los tswj cov haujlwm hauv RAM thiab cache. Tshwj xeeb tshaj yog, Spoiler tuaj yeem nkag mus rau qee qhov chaw nyob cov ntaub ntawv (saum toj no qhov chaw nyob me ntsis 11) thaum lub sijhawm ua haujlwm khau raj. Thiab AMD processors tsis siv ib feem qhov chaw sib tw saum toj no qhov chaw nyob me ntsis 11 thaum daws teeb meem khau raj.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txawm hais tias Spoiler, zoo li Spectre, tso siab rau cov txheej txheem rau kev ua tiav cov lus qhia, nws yuav tsis tuaj yeem kaw qhov tsis muaj zog tshiab nrog "patch" uas twb muaj lawm los ntawm kev siv yav dhau los. Ntawd yog, tam sim no Intel processors xav tau thaj ua rau thaj tshiab, uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov chips. Thiab yav tom ntej, Intel yuav, ntawm chav kawm, xav tau kev kho ntawm qib architecture. AMD yuav tsis tas yuav ua li ntawd.
Thaum kawg, peb nco ntsoov tias Spoiler cuam tshuam rau tag nrho Intel processors, pib nrog thawj tiam Core chips thiab xaus nrog Coffee Lake Refresh tam sim no, nrog rau qhov tseem tsis tau tso tawm Cascade Lake thiab Ice Lake. Txawm hais tias qhov tseeb tias Intel nws tus kheej tau ceeb toom txog qhov teeb meem thaum pib lub Kaum Ob Hlis xyoo tas los, thiab ntau tshaj kaum hnub tau dhau los txij li Spoiler tau tshaj tawm rau pej xeem, Intel tsis tau nthuav tawm cov kev daws teeb meem rau qhov teeb meem thiab tseem tsis tau tshaj tawm cov lus tshaj tawm hauv qhov no hais txog.
