Dual Core vs Quad Core

Dual core thiab quad core yog ob hom processor uas poob rau hauv qeb ntawm ntau tus tub ntxhais kawm. Nyob rau hauv ib tug multi-core processor, muaj ntau tshaj ib tug tub ntxhais (processor) nyob rau hauv ib tug integrated circuit tuag. Ib tug dual core processor muaj ob cores nyob rau hauv tib tug tuag thiab ib tug quad core processor muaj plaub cores nyob rau hauv tib tuag. Multi core processors yog dav siv nyob rau hauv lub hom phiaj lub hom phiaj computers, embedded li, network pab kiag li lawm, thiab lwm yam. Yuav kom tau txais qhov zoo tshaj plaws kev siv ntawm multi-core processors, cov software cov kev pab cuam uas khiav ntawm lub system yuav tsum tau siv nyob rau hauv xws li ib tug txoj kev uas lawv muaj peev xwm tau txais cov kev pab cuam ntawm cov tub ntxhais processors. kev siv tag nrho ntawm kev teeb tsa multi core.

Dual Core yog dab tsi?

Dual core processors muaj ob lub processor cores hauv tib qho tuag. Thiab txhua lub cores muaj nws tus kheej cache. Hauv cov txheej txheem ib txwm ua haujlwm, thaum ua tiav cov lus qhia, yog tias cov ntaub ntawv xav tau tsis nyob hauv lub cache, cov ntaub ntawv yuav tsum tau nqa los ntawm RAM (Random Access Memory) lossis los ntawm cov cuab yeej cia, uas yuav ua rau kev ua tiav qeeb txij li lub processor muaj. tos kom txog thaum nws tau txais cov ntaub ntawv. Tab sis nrog ob cores, txhua tus tub ntxhais ua tiav cov lus qhia nyias thiab yog li thaum ib tus tub ntxhais nkag mus rau lub cim xeeb lwm tus tub ntxhais tseem yuav ua tiav cov lus qhia. Qhov no yuav txhim kho kev ua haujlwm ntawm qhov system. Tshwj xeeb tshaj yog nrog kev ua haujlwm ntau, yog tias tsuas muaj ib lub processor xwb, qhov kev ua tau zoo yuav raug kev txom nyem vim lub processor yuav tsum tau hloov ntawm ob txheej txheem. Yog li kev ua haujlwm ntau tuaj yeem ua tiav nws qhov kev ua tau zoo tshaj plaws yog tias muaj ntau tshaj ib qho tseem ceeb. AMD Phenom II X2 thiab Intel Core Duo yog ob qho piv txwv ntawm dual core processors.

Quad Core yog dab tsi?

Quad core processor yog lub processor nrog plaub cores hauv tib qhov tuag. Tab sis, thawj quad core processors muaj txhua tus tub ntxhais sib cais hauv plaub qhov tuag thiab lawv tau muab tso rau hauv ib pob los tsim ib lub quad core processor. Tom qab ntawd tuaj cov processors nrog tag nrho plaub cores nyob rau hauv tib neeg tuag thiab lawv hu ua Monolithic plaub-core processors. Tsis tas li ntawd, qee qhov quad core processors yog tsim los ntawm kev sib txuas ob lub dual core processors rau hauv ib pob. Quad core processors muaj peev xwm ua tau plaub yam lus qhia sib txawv tib lub sijhawm. Yog li, cov no tsim nyog rau kev khiav ntau daim ntawv thov ib txhij. Tab sis feem ntau ntawm cov ntawv thov tsis tau tsim los ua kom zoo dua ntawm quad core peev xwm. Lawv yog tsim los rau ib tug core processors. Cov ntawv thov uas tau tsim los khiav ntau txoj haujlwm ib txhij yuav muaj peev xwm ua kom zoo dua ntawm quad core processor.

Qhov txawv ntawm Dual Core thiab Quad Core yog dab tsi?

Dual core processors muaj ob lub processor cores nyob rau hauv tib qhov tuag whereas quad core processor yog ib tug processor nrog plaub cores nyob rau hauv tib tuag. Yog li ntawd, lub khoos phis tawj nrog quad core processor yuav tsum ua tau zoo dua li lub khoos phis tawj nrog lub processor dual. Tab sis qhov no yuav tsis yog ib txwm muaj tseeb vim tias feem ntau ntawm cov ntawv thov raug tsim los tsom rau ib puag ncig lossis dual tub ntxhais ib puag ncig. Yog li ntawd, lawv yuav tsis tuaj yeem ua kom zoo dua ntawm kev txhim kho kev ua tau zoo los ntawm quad core processors.
