2.2 vs 2.3 vs 2.7 MacBook Pro
Processor ceev yog dab tsi?
Processor ceev yog qhov ceev uas lub processor muaj peev xwm ua kom tiav ib qho ntawm cov voj voog ib ob. Processor ceev yog ntsuas hauv Hertz. Hauv cov ntsiab lus yooj yim, yog tias lub processor ceev yog 1 hertz uas txhais tau hais tias tus processor tuaj yeem ua tiav ib lub voj voog hauv ib thib ob. Gigahertz yog qhov ntau tshaj plaws ntawm processor speeds hnub no. 1 gigahertz txhais tau hais tias lub processor ua tiav ib txhiab cycles ib ob. Overclocking yog cov txheej txheem ntawm kev khiav lub processor ntawm qhov nrawm dua li nws tau tsim los. Tab sis cov txiaj ntsig ntawm overclocking yog nyob ntawm cov cua kub ntxiv hauv cov processor vim overclocking.
Nyob rau xyoo tas los no, moos ceev tau nce sai heev. Tab sis tam sim no nws tau saturated vim tias nws nyuaj heev kom nce tus nqi tshaj 3.5 GHz vim lub cev muaj kev txwv tam sim no hauv kev tsim khoom. Txawm li cas los xij, vim yog qhov kev taw qhia ntawm processor cores (piv txwv li ob chav tub ntxhais), cov tuam txhab lag luam hauv computer nrhiav txoj hauv kev los ua kom muaj txiaj ntsig zoo ntawm tag nrho cov kab ke.
YMacBook Pro
MacBook Pro yog ib qho kev tshaj lij Macintosh phau ntawv tso tawm los ntawm Apple hauv 2006 ua thawj cov khoom lag luam hauv MacBook tsev neeg. Nws yog qhov kawg ntawm MacBook tsev neeg. MacBook Pro siv Intel Core i5 thiab i7 processors (qhia txog Thunderbolt thev naus laus zis) thiab hloov PowerBook kab. MacBook Pro muaj 13.3 '', 15.4 '' thiab 17 '' qauv. Cov ntxaij vab tshaus loj tshaj plaws ntawm 1440 × 900 lossis 1680 × 1050 (15.4 ') thiab 1920 × 1200 (17 ') muaj nrog MacBook pro. MacBook Pro muaj peb USB 2.0 chaw nres nkoj thiab FireWire 800. Muaj ob lub MacBook Pro tsim, ob qho tib si siv txhuas. Ib qho yog nqa tawm los ntawm PowerBook series thiab lwm qhov yog unibody tapered tsim. MacBook Pro los nrog 2GB RAM. Txawm li cas los xij, tus neeg siv muaj qhov kev xaiv ntawm kev txhim kho 4GB RAM thaum yuav khoom.
Qhov txawv ntawm 2.2 thiab 2.3 thiab 2.7 MacBook Pro yog dab tsi?
Txhua MacBook cov khoom lag luam hauv Australian lub lag luam tam sim no muaj dual-core lossis quad-core processors, Intel core i5 lossis i7, 4GB (1333 MHz), 320GB lossis siab dua hard disks (5400rpm) thiab Intel HD Graphics 3000. Muaj ob yam khoom siv 2.2 GHz (15-nti thiab 17-nti), uas yog kim dua li 2.3 thiab 2.7 GHz. Tus nqi siab dua (txawm tias qhov ceev qis dua) vim tias kev txhim kho hauv lwm qhov chaw (xws li 760GB hard disks tshaj 500/320 GB thiab suav nrog AMD Radeon GDDR5). Ob qho khoom siv 2.2 GHz yog kim tshaj li 2.0 GHz cov khoom, uas yuav luag tib yam specifications (tshwj tsis yog cov processor ceev). 2.7 GHz MackBook Pro yog kim tshaj li 2.3 GHz cov khoom (uas muaj cov lus qhia zoo sib xws hauv yuav luag txhua qhov chaw, tsuas yog qhov txawv ntawm Intel core i7 vs. i5 thiab 500GB nyuaj vs.320 GB).
Sib piv ntawm cov txheej txheem nrawm
Feem ntau, qhov nrawm dua txhais tau tias tus nqi ntawm lub khoos phis tawj siab dua. Ntawm qhov tod tes, kev nrawm dua ib txwm tso cua sov ntau dua yog li nws yuav xav tau cov tshuab cua txias zoo dua. Lub moos ceev ntawm CPU tsuas yog tsim nyog rau kev sib piv CPUs ntawm tib tsev neeg (vim tias muaj ntau lwm yam cuam tshuam rau CPU kev ua tau zoo xws li qhov dav ntawm CPU cov ntaub ntawv tsheb npav, nco latency thiab cache specifications).
