Vratislav Holub Kev tuaj txog ntawm Apple Silicon tau ua rau lub sijhawm tshiab ntawm Apple computers. Qhov no yog vim peb tau txais kev ua tau zoo dua thiab kev siv hluav taws xob qis dua, uas ua rau lub neej tshiab rau Macs thiab ua rau lawv muaj koob meej. Txij li cov chips tshiab yog qhov tseem ceeb dua kev lag luam piv rau cov txheej txheem los ntawm Intel, lawv tsis txawm raug kev txom nyem los ntawm cov teeb meem nto moo nrog overheating thiab xyaum ib txwm ua kom "lub taub hau txias".
Nws yuav yog txaus siab rau koj
Tom qab hloov mus rau Mac tshiab nrog Apple Silicon nti, ntau tus neeg siv Apple xav tsis thoob thaum pom tias cov qauv no tsis tuaj yeem ua kom sov. Cov pov thawj tseeb yog, piv txwv li, MacBook Cua. Nws yog qhov kev lag luam uas nws tuaj yeem ua tiav yam tsis muaj kev ua kom txias nyob rau hauv daim ntawv ntawm tus kiv cua, uas tsuas yog tsis tuaj yeem ua tau yav dhau los. Txawm li cas los xij, Cua tuaj yeem yooj yim tiv nrog, piv txwv li, kev ua si. Tom qab tag nrho, peb tso qee lub teeb rau qhov no hauv peb tsab xov xwm txog gaming ntawm MacBook Cua, thaum peb sim ob peb lub npe.
Vim li cas Apple Silicon tsis overheat
Tab sis cia peb mus rau qhov tseem ceeb tshaj plaws, lossis yog vim li cas Macs nrog Apple Silicon nti tsis ua kom sov ntau. Ob peb yam ua si hauv kev pom zoo ntawm cov chips tshiab, uas tom qab kuj ua rau qhov zoo tshaj plaws. Thaum pib, nws yog qhov tsim nyog los hais txog qhov sib txawv architecture. Apple Silicon chips yog tsim los ntawm ARM architecture, uas yog ib txwm siv rau hauv, piv txwv li, xov tooj ntawm tes. Cov qauv no muaj kev lag luam ntau dua thiab tuaj yeem ua tau yooj yim yam tsis muaj cua txias yam tsis muaj kev poob haujlwm hauv txhua txoj kev. Kev siv cov txheej txheem tsim khoom 5nm kuj tseem ua lub luag haujlwm tseem ceeb. Hauv txoj ntsiab cai, qhov me me ntawm cov txheej txheem ntau lawm, qhov ua tau zoo thiab kev lag luam ntawm cov nti yog. Piv txwv li, rau 5-core Intel Core i3,0 nrog zaus ntawm 4,1 GHz (nrog Turbo Boost txog 14 GHz), uas ntaus nyob rau hauv tam sim no muag Mac mini nrog Intel CPU, yog raws li XNUMXnm cov txheej txheem ntau lawm.
MacBook Air nrog M2 (2022)
Txawm li cas los xij, qhov tseem ceeb tshaj plaws yog kev siv hluav taws xob. Ntawm no, kev sib raug zoo ncaj qha siv - qhov ntau dua qhov kev siv hluav taws xob, qhov yuav ua rau muaj cua sov ntxiv. Tom qab tag nrho, qhov no yog qhov tseeb vim li cas Apple bets ntawm kev faib cov cores rau hauv kev lag luam thiab muaj zog hauv nws cov chips. Rau kev sib piv, peb tuaj yeem nqa Apple M1 chipset. Nws muaj 4 cores muaj zog nrog qhov siab tshaj plaws ntawm 13,8 W thiab 4 kev lag luam cores nrog kev siv siab tshaj plaws ntawm 1,3 W. Nws yog qhov sib txawv tseem ceeb uas ua lub luag haujlwm tseem ceeb. Txij li thaum lub sijhawm ua haujlwm hauv ib txwm ua haujlwm (xws li Internet, sau ntawv e-mail, thiab lwm yam) lub cuab yeej siv tsis muaj dab tsi, nws tsis muaj qhov xav tau los ua kom sov. Ntawm qhov tsis sib xws, tiam dhau los ntawm MacBook Cua yuav muaj kev noj 10 W hauv qhov xwm txheej zoo li no (ntawm qhov qis tshaj plaws).
Kev ua kom zoo
Txawm hais tias Apple cov khoom yuav tsis zoo li zoo tshaj plaws ntawm daim ntawv, lawv tseem muaj qhov ua tau zoo thiab ua tau ntau dua lossis tsawg dua yam tsis muaj teeb meem. Tab sis tus yuam sij rau qhov no tsis yog kho vajtse xwb, tab sis nws zoo optimization nyob rau hauv ua ke nrog software. Qhov no yog qhov tseeb uas Apple tau ua raws nws cov iPhones rau ntau xyoo, thiab tam sim no nws tau hloov pauv cov txiaj ntsig zoo ib yam rau lub ntiaj teb ntawm Apple cov khoos phis tawj, uas, ua ke nrog nws tus kheej chipsets, yog nyob rau theem tshiab kiag li. Optimizing lub operating system nrog lub hardware nws tus kheej yog li bears txiv hmab txiv ntoo. Ua tsaug rau qhov no, cov ntawv thov lawv tus kheej yog me ntsis maj mam thiab tsis tas yuav muaj lub zog zoo li no, uas ib txwm txo lawv cov txiaj ntsig ntawm kev noj thiab kev tsim hluav taws xob tom ntej.
Nws yuav yog txaus siab rau koj
Nws yog qhov lom zem tiag tiag los sib piv "xyoo pua" i5 ntawm 14nm nrog SoCs tam sim no ntawm 5/4nm. Lub "apple silicon" architecture ib leeg yeej tsis muaj qhov ua tau zoo (txawm tias zoo li tam sim no i5). Kua thawj koom ruam ntawm tshwj xeeb accelerators (coprocessors). Qhov hais txog kev ua kom zoo dua ntawm OS ntawm lawv SoC yog li coj qhov "zoo siab" kev ua haujlwm. Tab sis - yog tias koj siv daim ntawv thov uas "apple silicon" tsis muaj cov txheej txheem sib txuas, qhov kev ua tau zoo yuav poob qis thiab yuav NW nyuam qhuav nyob rau theem qis tshaj i3. Ntawm qhov tod tes, i5 tau hais los saum toj no ua "tsis zoo sib npaug" hauv txhua hom haujlwm (tsis suav nws cov duab tragic). Tau kawg, kuv tsis tau hais tias "apple silicon" SoCs phem, Kuv tsuas yog piav qhia qhov txawv. x86 tau yooj yim rub tawm kev sib raug zoo txij li xyoo 1976 (!), yog li software txij li lub sijhawm ntawd tuaj yeem khiav ntawm x86 CPUs / SoCs niaj hnub no. Uas yog ib qho teeb meem ntawm "slowness" ntawm x86 piv rau "apple-optimized" aarch64 architecture…
Zoo, Intel muaj nws tus kheej los liam rau qhov ntawd, vim nws tseem tso tawm cov txheej txheem tshiab nrog 14nm processors. Thaum koj sib piv cov kev ua yeeb yam ntawm tus kheej cov txheej txheem tshiab, koj tsis tuaj yeem pom qhov kev hloov pauv tseem ceeb xyoo-rau-xyoo! Intel tau so ntawm peb cov laurels me ntsis thiab tam sim no lawv tau them rau nws.
