Sezvinotevera kubva kune ruzivo rwakataurwa naJim Keller, mutevedzeri wemutungamiri wetekinoroji uye system architecture kuIntel, kambani yake parizvino iri kushanda mukugadzira hunyanzvi hutsva hwekuvaka, hunofanirwa kuve "hwakakura uye padyo nekutsamira kwemutsara wekuita. pahuwandu hwema transistors,β kupfuura dhizaini yemazuva ano yeSunny Cove. Sezviri pachena, izvi zvinofanirwa kududzirwa nenzira yekuti mumakore mashoma isu tichagamuchira processor ichave yakanyanya kuomarara uye ine simba zvakanyanya kupfuura maCPU anopihwa neiyo microprocessor hofori parizvino.
Iyo nyowani Sunny Cove microarchitecture, iyo Intel inoshandisa mune itsva Ice Lake chizvarwa processors, yave budiriro yakakomba, sezvo mushure mekuzorora kwenguva yakareba yakawedzera zvinooneka IPC (nhamba yemirairo yakaitwa pawachi kutenderera). Asi processor guru Jim Keller, anoshanda kuIntel parizvino, anoti izvi zviri kure nekumagumo. Iye zvino ari kushanda pachizvarwa chinotevera che microarchitecture, icho chichakwanisa kushandisa zvizere kuwedzera kwakawanda kwebhajeti ye transistor inotarisirwa mumakore mashoma anotevera.
Zvinoenderana nefungidziro yeIntel, mukana weSunny Cove cores uchienzaniswa neKofi Lake cores mune chaiyo mashandiro anosvika 15-18% (panguva imwechete yekumhanyisa wachi). Nekudaro, iyo transistor bhajeti yeSunny Cove inodarika iyo bhajeti yeyakatangira neyakanyanya kukosha - yakatenderedza 38%. Zvinoenderana neruzivo rwakaziviswa naKeller, musimboti neSunny Cove microarchitecture ine angangoita 300 miriyoni 10-nm transistors, nepo iyo Coffee Lake musimboti inosanganisira angangoita 217 miriyoni 14-nm transistors. Zvinoitika kuti kukura kwechigadzirwa muSunny Cove hakusviki kune mutsara kutsamira pahukuru hweiyo transistor bhajeti: kufambira mberi mukugadzirwa kwakave kunenge hafu nekukurumidza sekuwedzera kwekuoma kweiyo semiconductor crystal. Sekureva kwaKeller, hazvifanirwe kunge zvakadaro.
Achipa hurukuro kuYunivhesiti yeBerkeley, nyanzvi inotungamira kubva kuIntel yakasimudza nyaya yekushanduka kwema microarchitectures eIntel processors uye munyaya haana kugara paSunny Cove, asi akataura angangove mutsivi weiyi microarchitecture: "Sunny Cove inoshanda na. 800 mirayiridzo panguva imwe chete, kuita kubva 3 kusvika 6 x86- mirairo pawachi ... Iine data guru rekufungidzira, guru rebazi rekufungidzira. Asi isu tiri kushanda pane microarchitecture chizvarwa icho chakakura zvakanyanya, uye mutemo wekukura kwekuita uri padyo nemutsara. Iko kuchinja kukuru mukufunga. "
Nzvimbo yeinjiniya wenyeredzi ndeyekuti processor tekinoroji ichiri kure nekusvika chero muganhu. Sekureva kwaKeller, Intel ine hurongwa hwekutarisira ramangwana, zvinosanganisira kuwedzera makumi mashanu-kukapetwa muhuwandu hwema transistors muma processors uye kuvandudzwa kukuru munenge mune yese inoshanda unit. Uye hapana chinhu chisingagoneki pamusoro peizvi. Sokutsanangura kunoita Keller: βMakombiyuta anogadzirwa nenhamba huru yevanhu, asi chaizvoizvo iboka guru rezvikwata zviduku. Iwe unogona kuvandudza fungidziro yebazi, iyo yekuraira seti, iyo dhizaini, ita optimizations, shandisa zvirinani maturusi ekugadzira uye maraibhurari ari nani. Huwandu hwenzvimbo dzakasiyana dzekushandisa uko kune nzvimbo yekuvandudza ichokwadi, yakakura kwazvo. "
Zvirongwa zveIntel zvazvino zveveruzhinji zvinosanganisira maviri iterations ye microarchitecture ekuwedzera kupfuura Sunny Cove. Iyo inotevera Willow Cove dhizaini inovimbiswa kuratidza shanduko kune cache subsystem uye kutamira kune nyowani semiconductor tekinoroji (ingangoita 7nm). Goridhe Cove ichabva yawedzera tambo-yakapetwa kuita uye kutarisa paAI basa rekutakura, pamwe nekugadzirisa kunodiwa kuita zvirinani pane XNUMXG network. Zvichida Jim Keller aive neGolden Cove mupfungwa mumushumo wake, kunyangwe pasina chakataurwa nezveizvi.
