Intel Mobile Processors Core i7 vs Core i7 Extreme Edition
Core i7 thiab Core i7 Extreme yog Intel cov txheej txheem ua haujlwm raws li Sandy Bridge architecture. Ntawm no peb yuav txheeb xyuas qhov sib txawv ntawm Intel Core i7-2820QM thiab Intel Core Extreme i7-2920XM. Inter Core i7-2820QM thiab Core i7 Extreme (i7-2920XM) ob leeg muaj yuav luag tib yam kev ua tau zoo thiab kev ua haujlwm tshwj tsis yog moos ceev, tsheb npav mus rau tub ntxhais piv, Max TDP thiab cov khoom siv txhawb nqa. Kev ua tau zoo thiab kev ntsuas ceev ntawm cov processors tau tham txog hauv qab no. Hauv kev xaus Intel core i7 Extreme (i7-2920XM) zoo dua Intel Core i7-2820QM.
Hyper-Threading Technology
Hyper-Threading Technology yog dab tsi?
Hyper-Treading Technology siv cov khoom siv processor zoo thiab ua tau zoo los ntawm kev khiav ntau cov xov ntawm txhua tus tub ntxhais. Yog li nws ua rau kom muaj kev sib tw, txhim kho kev ua tau zoo tag nrho ntawm cov software threaded.
Hyper-Threading thev naus laus zis yog siv los ntawm Intel cov tub ntxhais los simulate ntau cores dua li cov cores tiag tiag. Piv txwv li i7 processor tsev neeg muaj 4 cores tab sis nws simulates li yim cores.
Max Turbo Boost zaus
Dab tsi yog Max Turbo Boost Technology thiab Max Turbo Boost zaus?
Max Turbo Boost Frequency yog lub moos siab tshaj plaws uas lub processor muaj peev xwm ua haujlwm siv Turbo Boost Technology. Intel tau tshaj tawm Turbo Boost Technology los muab kev ua haujlwm ntau dua thaum xav tau. Cov thev naus laus zis no tau qhia hauv microarchitecture ntawm Sandy Bridge. Qhov tseeb version ntawm Turbo Boost yog 2.0, qhov no cia li tso cai rau processor cores khiav nrawm dua li lub hauv paus zaus thaum nws ua haujlwm hauv qab lub zog, tam sim no thiab kub. Qhov Turbo Boost no tau qhib thaum Lub Chaw Haujlwm (Ex: Windows) thov kom muaj kev ua haujlwm siab ntawm lub xeev.
Core i7-2820QM txhawb nqa mus txog 3.4 GHz turbo boost zaus thiab Core i7 Extreme (i7-2920XM) txhawb txog 3.5 GHz.
Clock Ceev
Processor moos ceev yog dab tsi?
moos ceev ntawm lub processor yog tus nqi uas tus processor tuaj yeem ua tiav lub voj voog ua haujlwm. Nws ib txwm ntsuas hauv MHz lossis GHz. Ib MHz (Mega Hertz) yog sib npaug rau ib lab cycles ib ob thiab ib GHz yog ib tug billion cycles ib ob. Yog li 2 GHZ processor yog ob zaug ceev moos ceev tshaj 1 GHz processor. Txawm li cas los xij nws tsis txhais hais tias 2 GHz processor yog ib txwm nrawm dua 1 GHz processor vim tias cov txheej txheem sib txawv siv cov qauv sib txawv.
Tab sis Core i7 thiab Core i7 Extreme ob leeg raws li Sandy Choj architecture kom peb tuaj yeem sib piv qhov nrawm nrog moos ceev ib yam.
Core i7 -2820QM los nrog 2.3 GHz thiab Core i7 Extreme (i7-2920XM) los nrog 2.5 GHz. Yog li peb tuaj yeem xaus Core i7-2920XM sai dua Core i7-2820QM.
Bus to Core Ratio
Bus mus rau Core (Bus / Core) Ratio hauv Computer Architecture yog dab tsi?
Nyob hauv Intel Architecture, Lub Tsheb Pem Hauv Ntej khiav hauv qhov nrawm nrawm thaum processor khiav hauv qhov sib txawv. Yog tias lawv nyob ze dua, processor yuav tsum tau tos tsawg lub voj voog hauv kev ua tiav. Nyob rau hauv txoj kev xav, qhov ze ntawm lub tsheb npav ceev yog rau lub nti, qhov kev ua haujlwm sai dua.
Intel Core i7-2820QM muaj Bus / Core piv ntawm 23 thiab Intel Core i7 Extreme (i7-2920XM) li 25.
Maximum TDP (Thermal Design Power)
TDP siab kawg ntawm tus txheej txheem yog dab tsi?
Qhov siab tshaj TDP yog qhov sib sau ntawm qhov siab tshaj TDP qhov tseem ceeb ntawm tus processor. TDP txhais tau tias Thermal Design Power uas yog lub zog ntawm cov cua txias hauv lub processor uas tuaj yeem ua rau cov cua sov tsis tau mus txog qhov siab tshaj plaws ntawm qhov sib txuas. Piv txwv li 55 Watts TDP txhais tau hais tias lub processor tuaj yeem tawg mus txog 55 Watts ntawm cov cua sov yam tsis muaj qhov kub siab tshaj qhov taw qhia tau hais tseg.
Max TDP ntawm Core i7-2820QM yog 45 Watts thiab Core i7 Extreme (i7-2920XM) yog 55 Watts.
