Yuav ua li cas yog clocked

Keeb kwm, lub CPU moos ceev yog qhov tseem ceeb qhia ntawm lub computer kev ua tau zoo, thiab nyob rau ib lub sij hawm txawm ib tug ruam tug neeg uas tsis paub dab tsi tus kho qhov muag disc yog txawv los ntawm lub saj zawg zog, tau mus rau lub xeev tseeb hais tias cov ntau gigahertz nyob rau hauv lub tsheb, lub zoo dua, thiab tsis muaj ib tug yuav kuv sib cav nrog nws. Niaj hnub no, nyob rau hauv nruab nrab ntawm lub computer era, qhov no zoo ntawm zam tau dhau, thiab lub developers tseem tabtom mus tau deb nyob rau hauv cov kev taw qhia ntawm kev tsim ib tug ntau zoo meej architecture, ua pes tsawg tus cache thiab tus xov tooj ntawm cores, tab sis lub moos zaus yog lub "huab tais" ntawm kev ua tau zoo. Nyob rau hauv ib tug general kev txiav txim zoo, qhov no yog lub xov tooj ntawm elementary hauj lwm (mus) hais tias tus processor yuav ua tau ib tug thib ob lub sij hawm.

Nws hais ntxiv hais tias lub siab lub CPU moos zaus, qhov ntau elementary hauj lwm tau ua ib tug computer, thiab thiaj li, tus ceev nws ua hauj lwm.

Lub moos zaus tshaj processors yog hom twg los ntawm ob mus rau plaub gigahertz. Nws yog txiav txim los ntawm txawj lub processor tsheb npav zaus ntawm ib tug tej yam ratio. Piv txwv li, Intel Processor Core i7 siv x20 d thiab ib lub tsheb npav zaus sib npaug zos rau 133 MHz, whereby lub processor moos zaus yog 2660 MHz.

Niaj hnub nimno processors: cache thiab ntsiav

Txawm tias muaj tseeb hais tias ua ntej lawm lub "multi-core" yog ib tug novelty ntawm lub lag luam hnub no yog yuav luag tsis muaj tub ntxhais ib leeg processors. Thiab muaj tsis muaj dab tsi ceeb nyob rau hauv no, vim hais tias cov computer kev lag luam yog tsis sawv tseem.

Nws yuav tsum yog li ntawd yuav ntshiab yuav ua li cas los mus txiav txim lub moos zaus rau lub processor, muaj ob tug los yog ntau tshaj nuclei.

Nws yog hais tias muaj yog ib qho misconception txog lub xam ntawm lub zaus ntawm xws processors. Piv txwv li: "Muaj ib tug dual-core processor clocked ntawm 1.8 GHz, li no nws tag nrho zaus yuav muaj 2 x 1.8 GHz = 3.6GGts, txoj cai?". Tsis yog, tsis ncaj ncees lawm. Tu siab, lub xov tooj ntawm cores tsis cuam tshuam rau zaum kawg moos speeds yog tias koj processor ua hauj lwm ntawm ib tug ceev ntawm 3 GHz, vim li ntawd nws ua hauj lwm thiab yuav tsum tau, tab sis nrog ib tug loj tus naj npawb ntawm cores rau kom nws cov kev pab, thiab qhov no, nyob rau hauv lem, heev kom efficiency.

Tsis txhob hnov qab tias rau ib tug niaj hnub processor yog tshwj xeeb tshaj yog ib qho tseem ceeb npaum li cas ntawm cache nco. Qhov no yog tus ceev tshaj computer nco, uas yog duplicated nyob rau hauv lub lag luam ntaub ntawv, uas yog yuav tsum tau kom sai nkag ntawm ib lub sij hawm.

Vim qhov no hom ntawm lub cim xeeb yog heev kim thiab laborious los tsim, nws cov nuj nqis yog tus me me, tab sis txaus rau cov tsis nyob rau hauv thiaj li yuav nce kev kawm ntawm cov tag nrho lub system tsis muaj kev hloov tsis xws li moos zaus.

Maximum CPU moos ceev thiab acceleration

Yuav ua li cas yuav koj lub computer yuav tau zoo, muaj ib hnub nws yog tseem outdated. Tab sis tsis muaj nws nyob rau hauv lub thoob khib nyiab, thiab nrog qhib lub hnab tawv pojniam khiav mus rau qhov ze electronics khw. Feem ntau cov niaj hnub ua thiab video card muab ib tug ntxiv (nyob rau hauv tas li ntawd mus rau lub Hoobkas) acceleration, thiab muaj ib tug zoo txias system, koj yuav tau tsa lub theem ntawm cov nominal zaus 200-300 GHz. Rau adventurers thiab lovers coob raws li muaj ib tug "overclocking" hu rau nyem tawm cov nyiaj pab ntau tshaj technology. Muaj coob tus neeg muab kev koom tes nyob rau hauv no txaus ntshai ua lag ua luam, yuav yooj yim overclock ib zaug xwb tub ntxhais processor mus txog 6-7 GHz, thiab ib txhia txawm muab ib cov ntaub ntawv kev ua tau zoo nyob rau hauv lub 8.2 GHz band.
