Lub ntsiab yam ntxwv ntawm lub processor uas yuav tsum tau mus nrhiav thaum yuav

Yog hais tias koj txiav txim siab mus sib sau ua ke ib lub computer, es yuav npaj txhij-ua ntim, nws yog tsim nyog los xav hais tias ua ntej dab tsi processor koj xav rau nruab rau hauv lub system unit. CPU yam ntxwv ua si ib qho tseem ceeb luag hauj lwm nyob rau hauv kev xaiv ib tug motherboard. Thiab nws, nyob rau hauv lem, muaj feem xyuam rau txhua tsav txhua yam. Nyob rau hauv lwm yam lus, Yog hais tias koj yuav tsis muaj zog qub tiam processor, koj yuav tsis tau ib tug tshiab motherboard. Ntawm cov hoob kawm, yuav ib yam dab tsi koj ua tau, tab sis nyob rau tib lub sij hawm teem nyob rau hauv lub computer xaiv lub processor thiab lub rooj tsavxwm - tsis muaj.

Cov yooj yim cov yam ntxwv ntawm cov processor yog raws li nram no:

• Connector, txwv tsis pub lub npe hu ua ib tug socket. Qhov no yog lub ntsiab taw tes hais tias koj xav tau them sai sai mus rau txoj kev xaiv lub motherboard mus rau lub CPU los yog vice versa. Lub Rooj Tswjhwm Saib muaj ib connector, tsim los rau ib hom ntawm processor. Piv txwv li, ib tug niam nrog socket LGA tshaj tsuas nrog processors uas muaj ib tug LGA775 socket.

• moos zaus. Qhov loj qhov nqi ntawm no zaus, ntau dua qhov lub lag luam processor yuav ua tau nyob rau hauv ib tug muab lub sij hawm ntawm lub sij hawm.

• Pem hauv ntej sab Bus. Xwb, Yog hais tias nyob rau hauv ib tug yooj yim txoj kev, lub zaus ntawm lub system tsheb npav processor. Qhov no yog xws li ib tug tshwj xeeb lub tsheb npav pab kev sib txuas lus channel thiab kis ntaub ntawv ntawm tag nrho cov pab kiag li lawm tsis pub dhau lub system unit nws tus kheej thiab lub CPU.

• Cache. Ib hom ntawm lub cim xeeb, tiam sis tsuas yog nyob rau hauv lub processor, uas ua hauj lwm pab raws li ib tug intermediary ntawm lub RAM-nco thiab lub CPU nws tus kheej.

Xav txog tus yam ntxwv ntawm lub processor thiab ib lub zuj zus rau ntau yam. Peb pib nrog cov connector. Thaum xaiv ib tug processor thiab motherboard xav tau ib puas feem pua paub tseeb tias cov connectors rau lub processor thiab lub motherboard yog tib yam. Txwv tsis pub, koj yuav tsum hloov ib yam dab tsi los ntawm lawv. Ntawm cov hoob kawm, tus newer thiab ntau haib processor, lub newer thiab ntau npaum yuav tsum tau them ib tug nqi, ntsig txog, nws yuav twb yuav xam nyob rau hauv lub tshiab thiab haib processor.

Piv txwv li, cov laus processors «Intel Celeron» mus rau lub connectors LGA775. Nyob rau tib lub connector yuav muab tso, thiab tseem ua «Intel Core 2 Duo» thiab «Intel Core 2 Quad». Nyob rau hauv no hais txog, qhov no socket yog pab tau, vim hais tias cov tib daim card yuav tsum muab ntsia ntau hom ntawm processors, uas txawv ob nyob rau hauv nqe thiab kev kawm ntawv.

Nws yuav tsum tau muab sau tseg tias thaum yuav ib lub CPU «Intel Core i3» yuav tsum xyuam xim rau cov cim ntawm ib qho kev processor koj. Vim hais tias muaj thawj thiab thib ob tiam, ob qho tib si ntawm uas pom tau hais tias yuav Core i3, thiab yog li txawv nyob. Tsis txhob xav yuam kev.

Lub moos ceev yog ib qho tseem ceeb point, tab sis nws tsis yog qhov tseem ceeb. Yog li ntawd tsis txhob saib cov nqi ntawm zaus, yuav tsum tau them lawv txog lub cache thiab chaw tos tsheb loj ceev. Yog hais tias qhov kev kawm, lub moos zaus yuav muab ntau zog. Yuav ua li cas los mus hloov lub zaus ntawm lub processor? Nws tsis yog yooj yim heev, thiab tsis yog txhua tus yuav tau daws raws li koj muaj peev xwm tswj kom lwj lub processor. Cov txheej txheem yog hais tias ua rau kom cov zaus ntawm acceleration. Koj muaj peev xwm ceev rau hauv lub "BIOS".

Qhov tseem ceeb dua yog suav tias yog lub cache. Yog hais tias lub processor yog tsis nkaus tshiab, nws muaj ob tug cache theem. Thiab yog hais tias tus tshiab, uas yog, lub xeem tiam, uas nyob rau hauv cov qauv, muaj yog cov thib peb-theem cache.

Vim lub fact tias cov cache khw muag khoom noj cov ntaub ntawv uas yog yuav tsum tau nyob rau hauv lub sij hawm ntawd, ces, qhov ntau cache nyob rau hauv lub processor, lub tsawg accesses rau lub RAM, raws li feem ntau tsim nyog yog twb nyob rau hauv. Tab sis yog hais tias tus qub qauv, cov ntaub ntawv yog muab tso rau cov uas tsis muaj, thiab raws li ib tug tshwm sim ntawm cov CPU pheej hais txog cov RAM. Qhov no slows thiab thiaj li ua tau zoo.

L1 cache yog rau tag nrho cov processors. Nco nws yog heev, heev me me, tab sis ceev heev. Nws yog tsim nyog rau lub internal xav tau kev pab ntawm cov CPU tub ntxhais. Piv txwv li, tus nqi ntawm lub cim xeeb feem ntau tsawg tshaj li 100kb. Tab sis lub L2 cache yog twb tsim rau cov lag luam, ntsig txog, nws yog txaus loj nyiaj ntawm lub cim xeeb. Tus tshiab, zoo qauv, nws nce mus txog 2-4 megabytes. Yog hais tias qhov tseeb tiam qauv yog muaj koj yuav L3-cache. Muaj ntxiv, tab sis muaj tsawg ceev.

Kuv xav kom koj nco ntsoov ib zaug dua hais tias tus processor yam ntxwv ua si ib qho tseem ceeb luag hauj lwm nyob rau hauv lub resulting kev kawm ntawm cov tag nrho lub computer.
