AMD, madzulo a kukhazikitsidwa kwa Zen 2, yalengeza za chitetezo ndi kusatetezeka kwa ma CPU ake ku ziwonongeko zatsopano.

Kwa chaka chopitilira kutulukira kwa Specter ndi Meltdown, msika wa purosesa wakhala uli pampanipani ndi kupezeka kwa zovuta zambiri zokhudzana ndi makompyuta ongopeka. Ambiri atengeke kwa iwo kuphatikizapo otsiriza ZombieLoad, zidapezeka kuti Intel chips. Zachidziwikire, AMD sinalephere kugwiritsa ntchito mwayiwu poyang'ana chitetezo cha ma CPU ake.

pa tsamba, yodzipatulira pachiwopsezo chofanana ndi Specter, kampaniyo inanena monyadira kuti: “Ku AMD, timapanga zinthu zathu ndi ntchito zathu tili ndi chitetezo. Kutengera kuwunika kwathu komanso kukambirana kwathu ndi ofufuza zachitetezo, timakhulupirira kuti zinthu zathu sizingavutike. Fallout, RIDL kapena ZombieLoad chifukwa cha kupezeka kwa macheke achitetezo a hardware muzomanga zathu. Sitinathe kubwereza zowopsa izi pazinthu za AMD ndipo tilibe umboni woti wina aliyense wakwanitsa izi. ” Ma CPU a AMD Akuti Sangathe Kuwonongeka Kwina MDS - Kutumiza kwa Store-to-Leak Forwarding.

Chifukwa cha kupezeka kwa ziwopsezo zatsopano komanso kufunikira kwa opanga kuyika zigamba zoyenera motsutsana nawo, mapurosesa a AMD atha kukhala opindulitsa kuposa mayankho a mpikisano, malinga ndi lipoti lodziyimira laposachedwa. kafukufuku, yoyendetsedwa ndi tsamba la Phoronix, kugwiritsa ntchito njira zonse zokonzera zovuta za purosesa zomwe zimagwirizanitsidwa ndi makompyuta ongoyerekeza kumabweretsa kuchepa kwa magwiridwe antchito a Intel CPU ndi avareji ya 16% (ndi Hyper-Threading olumala - ndi 25%). Pankhani ya mapurosesa a AMD Zen +, magwiridwe antchito amatsika ndi 3% yokha.

Choyipa kwambiri: Apple ndi Google langizani Ogwiritsa ntchito a Intel ayenera kuletsa Hyper-Threading, yomwe nthawi zina imatha kuchepetsa magwiridwe antchito mpaka 40-50% (kutengera ntchitoyo). Intel yokha amalimbikitsa kusachita izi nthawi zambiri, koma vuto lingakhale lovuta kwambiri kwa malo ogwirira ntchito, ma seva ndi madera ena ogwira ntchito ndi chitetezo. Pankhani ya tchipisi ta AMD, kuletsa ukadaulo wa Simultaneous Multi-Threading sikufunika. Komanso, kusefukira kwa nkhani za zofooka, kuphatikizapo zokhudza Intel amayesa kubisa zambiri kuchokera kwa anthu sangathe koma kukhudza chithunzi cha womalizayo.

Nkhaniyi imabwera panthawi yoyipa kwambiri kwa Intel: AMD yatsala pang'ono kumasula banja la ma 7nm CPU apamwamba omwe ali ndi zomangamanga za Zen 2 zamakompyuta ndi ma seva. Pakadali pano, Intel akugwiritsabe ntchito zakale kwambiri (kuchokera pamalingaliro a chitukuko chaukadaulo) ukadaulo wa 14-nm ndipo sangathe kuyambitsa kusindikiza kwakukulu kwa tchipisi ta 10-nm. Zonsezi zimasewera m'manja mwa AMD, zomwe zitha kupitiliza kukulitsa msika wake chifukwa cha izi.
