Jim Keller: Ma Microarchitectures omwe akubwera a Intel apereka phindu lalikulu

Potsatira zomwe Jim Keller, wachiwiri kwa purezidenti wamkulu waukadaulo ndi zomangamanga ku Intel, adauza dziko lonse lapansi, kampani yake ikugwira ntchito yopanga zomangamanga zatsopano, zomwe ziyenera kukhala "zokulirapo komanso kuyandikira kudalira kwa magwiridwe antchito. pa chiwerengero cha ma transistors,” kusiyana ndi kamangidwe kamakono ka Sunny Cove. Mwachiwonekere, izi ziyenera kutanthauziridwa mwanjira yakuti m'zaka zingapo tidzalandira purosesa yomwe idzakhala yovuta kwambiri komanso yamphamvu kwambiri kuposa ma CPU omwe chimphona cha microprocessor chimapereka panopa.

Zatsopano zatsopano za Sunny Cove microarchitecture, zomwe Intel amagwiritsa ntchito mu processors zatsopano za Ice Lake, zakhala zopambana kwambiri, popeza patadutsa nthawi yayitali zawonjezera IPC (chiwerengero cha malangizo omwe amaperekedwa pa wotchi iliyonse). Koma purosesa wamkulu Jim Keller, yemwe pano akugwira ntchito ku Intel, akuti izi zili kutali ndi mapeto. Tsopano akugwira ntchito pa m'badwo wotsatira wa microarchitecture, womwe udzatha kugwiritsa ntchito bwino kuwonjezereka kochuluka kwa bajeti ya transistor yomwe ikuyembekezeka pazaka zingapo zikubwerazi.

Malinga ndi kuyerekezera kwa Intel, mwayi wa Sunny Cove cores poyerekeza ndi Coffee Lake cores mu magwiridwe antchito amafika 15-18% (pa liwiro la wotchi yomweyo). Komabe, bajeti ya transistor ya Sunny Cove imaposa bajeti ya omwe adatsogolera ndi kuchuluka kwakukulu - pafupifupi 38%. Malinga ndi chidziwitso chomwe Keller adawululira, pakatikati ndi Sunny Cove microarchitecture imakhala ndi ma transistors pafupifupi 300 miliyoni a 10-nm, pomwe pakatikati pa Coffee Lake pali ma transistors pafupifupi 217 miliyoni a 14-nm. Zikuoneka kuti kukula kwa zokolola ku Sunny Cove sikufikira kudalira kwamtundu wa kukula kwa transistor bajeti: kupita patsogolo kwa zokolola kunakhala pafupifupi theka lachangu monga kuwonjezeka kwa zovuta za semiconductor crystal. Malinga ndi Keller, siziyenera kukhala chonchi.

Polankhula ku yunivesite ya Berkeley, katswiri wotsogola ku Intel adadzutsa nkhani yakusintha kwa ma processor a Intel ndipo m'nkhaniyi sanakhazikike pa Sunny Cove, koma adatchulapo wolowa m'malo mwa kamangidwe kameneka: "Sunny Cove amagwira ntchito ndi Malangizo 800 nthawi imodzi, kuchita kuchokera ku 3 mpaka 6 x86- malangizo pa koloko ... Ili ndi zolosera zazikulu za data, zolosera zazikulu za nthambi. Koma tikugwira ntchito m'badwo wa microarchitecture womwe ndi waukulu kwambiri, ndipo lamulo la kukula kwa ntchito liri pafupi ndi mzere. Ndi kusintha kwakukulu m'malingaliro. "

Udindo wa injiniya wa nyenyezi ndikuti ukadaulo wa purosesa ukadali kutali kuti ufikire malire aliwonse. Malinga ndi Keller, Intel ali ndi zolinga zokhumba zamtsogolo, zomwe zikuphatikizapo kuwonjezeka kwa 50 kwa chiwerengero cha transistors mu processors ndi kusintha kwakukulu pafupifupi pafupifupi gawo lililonse la ntchito. Ndipo palibe chosatheka pa izi. Monga momwe Keller akulongosolera: “Makompyuta amapangidwa ndi chiŵerengero chachikulu cha anthu, koma kwenikweni ndi chiŵerengero chachikulu cha timagulu tating’ono. Mutha kukonza zolosera za nthambi, magawo a malangizo, kapangidwe kake, kukhathamiritsa, kugwiritsa ntchito zida zopangira bwino komanso malaibulale abwino. Kuchuluka kwa malo osiyanasiyana ogwiritsira ntchito komwe kuli malo opangira zatsopano ndikokulirapo kwambiri. ”

Mapulani apagulu a Intel akuphatikizanso kubwereza kuwiri kwa zomangamanga zazing'ono kupitilira Sunny Cove. Mapangidwe otsatirawa a Willow Cove alonjezedwa kuti awonetsa kusintha kwa kachesi kakang'ono ndikusunthira kuukadaulo watsopano wa semiconductor (mwina 7nm). Golden Cove idzakulitsa magwiridwe antchito a ulusi umodzi ndikuyang'ana kwambiri ntchito za AI, komanso kukhathamiritsa kofunikira kuti mugwire bwino ntchito pamanetiweki a XNUMXG. Mwina Jim Keller anali ndi Golden Cove m'malingaliro mu lipoti lake, ngakhale palibe chomwe chinanenedwa mwachindunji za izi.
