Kuna informatsiooni, mille jagas maailmaga Intel'i tehnoloogia ja s\u00fcsteemi arhitektuuri asepresident Jim Keller, t\u00f6\u00f6tas tema ettev\u00f5te praegu t\u00e4iesti uue mikroarhitektuuri loomise kallal, mis peaks olema \u201esignifikantsem ja l\u00e4hemal lineaarsele s\u00f5ltuvusele j\u00f5udluse ja transistorite arvu vahel\u201d, kui kaasaegne Sunny Cove disain. Tundub, et see tuleks t\u00f5lgendada nii, et paar aasta p\u00e4rast saame protsessori, mis on oluliselt keerukam ja oluliselt t\u00f5husam kui need CPU-d, mida mikroprotsessorigigant praegu pakub.<\/p>\n

Intel'i uusimate Ice Lake'i protsessorite genereeritud Sunny Cove'i mikroarhitektuur on t\u00f5eline l\u00e4bimurdepunkt, kuna see on p\u00e4rast pikka pausi oluliselt t\u00f5stnud IPC (t\u00e4itmise k\u00e4igus instruktsioonide arvu). Kuid protsessoriekspert Jim Keller, kes hetkel t\u00f6\u00f6tab Intel'is, \u00fctleb, et see pole kaugeltki l\u00f5pp-punkt. Ta t\u00f6\u00f6tab praegu j\u00e4rgmise p\u00f5lvkonna mikroarhitektuuri kallal, mis suudab t\u00e4ielikult \u00e4ra kasutada mitmekordset transistoribud\u017eeti suurenemist, mida oodatakse l\u00e4hiaastatel.<\/p>\n

\"Jim<\/p>\n

Intel'i hinnangute kohaselt ulatub Sunny Cove'i tuumade eesn\u00e4\u00e4rme Coffee Lake'i tuumade ees 15\u201318% (samas taktsageduses) saavutatud erapoolikuse \u00fcle. Samas \u00fcletab Sunny Cove'i transistorieelarve eelk\u00e4ija oma t\u00f5sise n\u00e4itaja - umbes 38%. Kelleri paljastatud teabe kohaselt sisaldab Sunny Cove mikroarhitektuuriga tuum umbes 300 miljonit 10 nm transistorit, samas kui Coffee Lake'i tuum sisaldab umbes 217 miljonit 14 nm transistorit. Seega on Sunny Cove'i j\u00f5udluse kasv alla lineaarsuse transistorieelarve suurusest: j\u00f5udluse edusammud on umbes kaks korda madalamad kui pooljuhtkristalli keerukuse kasv. Kelleri arvates ei tohiks see nii olla.<\/p>\n

Berkeley \u00fclikoolis loengut pidades mainis Intel'i juhtiv spetsialist Intel'i protsessorite mikroarhitektuuride arengut ning ei piirdunud Sunny Cove'i aruteluga, vaid mainis ka selle mikroarhitektuuri v\u00f5imalikku j\u00e4rglast: «Sunny Cove t\u00f6\u00f6tleb korraga 800 k\u00e4sku, t\u00e4ites 3 kuni 6 x86-k\u00e4sku iga takti jooksul\u2026 Seal on suured andmeprognoosijad, suured haruprognoosijad. Kuid me t\u00f6\u00f6tame j\u00e4rgmise mikroarhitektuuri p\u00f5lvkonna kallal, mis on m\u00e4rkimisv\u00e4\u00e4rselt v\u00f5imsam ning mille j\u00f5udluse kasv on l\u00e4hemal lineaarsele. See on t\u00f5eliselt suur m\u00f5tteviisi muutus».<\/p>\n

<\/center><\/p>\n

T\u00e4heinseneri roll seisneb selles, et protsessoritehnoloogia on veel kaugel hetkest, mil oleks saavutatud mingi piir. Nagu Keller \u00fctleb, on Intelil tulevikuks ambitsioonikad plaanid, sealhulgas transistorite arvu viiekordne suurendamine protsessorites ja m\u00e4rkimisv\u00e4\u00e4rsed t\u00e4iustused peaaegu igas funktsionaalses plokis. Ja selles ei ole midagi v\u00f5imatut. Keller selgitab: \"Arvuteid loob tohutult palju inimesi, kuid tegelikult on see suur hulk v\u00e4ikeseid gruppe. Ennustuste, k\u00e4skluste komplekti, arhitektuuri parendamine, optimeerimine, arenenumate disainit\u00f6\u00f6riistade ja parimate raamatukogude kasutamine. Erinevaid rakenduskohti, kus innovatsiooniks ruumi on, on tegelikult v\u00e4ga ja v\u00e4ga palju.\"<\/p>\n

\"Jim<\/p>\n

Intel'i praegused avalikud plaanid h\u00f5lmavad kahte mikroarhitektuuri t\u00e4iustamise iteratsiooni p\u00e4rast Sunny Cove'i. J\u00e4rgmises disainis, Willow Cove'is, nagu lubatud, on oodata muudatusi vahem\u00e4lu alams\u00fcsteemis ning \u00fcleminekut uuele pooljuhttehnoloogiale (t\u00f5en\u00e4oliselt 7 nm). Seej\u00e4rel suurendab Golden Cove \u00fchetuuma j\u00f5udlust ja keskendub tehisintellekti \u00fclesannete t\u00f6\u00f6tlemisele koos optimeeringutega, mis on vajalikud parema j\u00f5udluse saavutamiseks viienda p\u00f5lvkonna v\u00f5rkudes. V\u00f5ib-olla m\u00f5tles Jim Keller oma ettekandes just Golden Cove'ile, kuigi selle kohta ei oldud konkreetselt midagi \u00f6eldud.<\/p>\n
