Zvose NeC CPU, CPU Cores, Clock Speed, uye More
Iyo inonzi processing unit (CPU) ndiyo inowanikwa mumakombiyuta iyo inofanirwa yekududzira nekuita mitemo yakawanda kubva pane imwe yemashini yemapuraneti uye software.
Mhando dzose dzemashandisi dzinoshandisa CPU, kusanganisira yedhidhiyo, laptop, uye tablet computers, mafoni-foni ... kunyange yako flat flat-screen terevhizheni.
Intel uye AMD ndiwo mazita maviri anonyanya kuzivikanwa eCupp manufacturers for desktops, laptops, uye sevhisi, apo Apple, NVIDIA, uye Qualcomm ndivo guru smartphone uye tablet ye CPU makenzi.
Iwe unogona kuona mazita mazhinji akasiyana-siyana anoshandiswa kurondedzera CPU, kusanganisira processor, computer protoor, microprocessor, central processor, uye "ubongo hwekombiyuta."
Makombiyuta anotarisa kana madhiyabhorosi akaoma dzimwe nguva anonyanya kutaurwa seCUU, asi zvikamu zve hardware zvinoshanda zvakasiyana zvakasiyana uye hazvina zvimwe zvakafanana neCPU.
Iko CPU Inoita Kuita Uye Iyo Yakawanika
Iko kemazuva ano CPU inowanzoita shoma uye yakareba, ine mafupi akawanda, akapoteredzwa, akabatanidza midziyo yesimbi pamusana wayo. Vamwe vakwegura veCUs vane pini panzvimbo yezvigadzirwa zvesimbi.
Iyo CPU inonamatira zvakananga kuC CPU "socket" (kana dzimwe nguva "slot") pane mamabhobho . Iyo CPU inopindirwa muchekete-pin-side-pasi, uye hove duku inobatsira kuchengetedza purogiramu.
Mushure mokunge mhanya kunyange kwenguva pfupi, maCCU emazuva ano anogona kutonhora zvikuru. Kuti ubatsire kubvisa kupisa uku, inenge nguva dzose inodiwa kusungira kunyura kwehuni uye mutambi zvakananga pamusoro peCUU. Kazhinji, izvi zvinouya zvakasungwa neCUU kutenga.
Zvimwe zvimwe zvekufema zvakanyanya zvakasarudzwa zvinowanikwawo, kusanganisira mvura yakonhorera kits uye shanduko kuchinja mauniti.
Sezvakataurwa pamusoro apa, haisi ma CPUs ane mapepa pamativi avo epasi, asi mune izvo zvinoita, mapepa anonyorera nyore. Ngwarira paunenge uchibata, kunyanya paunenge uchiisa mubhodhibhodhi.
CPU Clock Speed
Hondo yeawa yepurogiramu ndiyo nhamba yemirayiridzo inogona kushanda mune imwe yechipiri yakapiwa, yakayerwa mu gigahertz (GHz).
Semuenzaniso, CPU ine nguva yeawa 1 Hz kana ikakwanisa kugadzirisa chikamu chimwe chekurayiridzo kwechipiri chepiri. Kuwedzera ichi ichi kune muenzaniso chaiwo-wenyika: CPU neawa reawa yeGear 3.0 GHz inogona kushanda mabhiriyoni matatu mirairo yega yechipiri.
CPU Cores
Zvimwe zvigadziri zvine imwe-core processor apo vamwe vanogona kuva ne-double-core (kana quad-core, etc.) processor. Sezvo zvingave zvichange zvave pachena, kuva nemaviri mapurisa ekushanda anoshanda pamwe chete zvinoreva kuti CPU inogona kuita panguva imwechete mirayiridzo yese yechipiri, ichivandudza kushanda.
Zvimwe CPUs zvinogona kuwedzera mahara maviri emhando yega yega yemuviri inowanika, inonzi Hyper-Threading. Virtualizing zvinoreva kuti CPU ine mavara mana chete inogona kuita sekunge iine masere, pamwe nehuwandu hweC CPU hunoti hutete hwakasiyana. Zvisikwa zvenyama, kunyange zvakadaro, zvinoshanda zviri nani kudarika zvikaita .
CPU inobvumira, mamwe maitiro anogona kushandisa izvo zvinonzi multithreading . Kana tambo inonzwisiswa sechinhu chimwe chete chekombiyuta, zvino kushandisa tsvina dzakawanda mune imwe nhengo yeCCU zvinoreva mamwe mazano anogona kunzwisiswa uye kushandiswa kamwechete. Zvimwe zvepurogiramu zvinogona kushandisa zvinyorwa izvi pane imwechete yeCC core, izvo zvinoreva kuti kunyanya mirayiridzo inogona kushandiswa panguva imwe chete.
Muenzaniso: Intel Core i3 vs. i5 vs. i7
Kuti uwane humwe muenzaniso chaiwo wekuti dzimwe CPUs dziri kukurumidza sei kune vamwe, ngatitarise kuti Intel yakagadzira sei mapurogiramu.
Sezvo iwe ungangodaro unofungidzira kubva kune zita ravo, Intel Core i7 chips inoita nani kupfuura i5 chips, iyo inoita nani kupfuura i3 chips. Chikonzero nei munhu anoita zviri nani kana kuti akaipa kudarika vamwe zvakaoma zvakanyanya asi zvichiri nyore nyore kunzwisisa.
Intel Core i3 mapurisa ndiwo maviri-core processors, asi i5 uye i7 chips ndeye-quad-core.
Turbo Boost inowanikwa muI5 uye i7 chips inoita kuti purogiramu iwedzere maawa ayo ekufambisa kupfuura nheyo yaro, kubva pa 3.0 GHz kusvika ku 3.5 GHz, chero ipi zvayo inoda. Intel Core i3 chips hauna uhwu. Maitiro ekugadzirisa mapepa ekupedzisira mu "K" anogona kunge akaputika , izvo zvinoreva kuti izvi zvinowedzera maawa masikati zvinogona kumanikidzwa uye kushandiswa nguva dzose.
Hyper-Threading, sezvakataurwa kare, inoita kuti tsvina mbiri dzigadziriswe pamusi wega wega CPU. Izvi zvinoreva i3 mapurogiramu neHyper-Threading kutsigirwa chete nhete dzomukati pamwe chete (sezvo dziri vaviri-core processors). Intel Core i5 vashanduri havatsigire Hyper-Threading, zvinoreva kuti ivowo, vanogona kushanda nematafura mana panguva imwechete. I7 vashanduri, zvisinei, vanobatsigira teknolojia iyi, uye naizvozvo (kuva quad-core) inokwanisa kutora tambo 8 panguva imwe chete.
Pamusana pezvipingamupinyi zvemasimba zvinowanikwa mune zvishandiso zvisina kuenderera mberi kwemasimba (zvinotengeswa nebheteri-zvakagadzirwa sefoni, mahwendefa, nezvimwewo), vashanduri vavo-pasinei kana vari i3, i5, kana i7-yakasiyana kubva pakombiyuta CPUs mune kuti vanofanira kuwana kuenzanisa pakati pekushandiswa uye simba rekushandisa.
Mamwe Mashoko pamusoro peCPUs
Handizvo maawa ekuvhara, kana kuti nhamba ye CPU cores, ndiyo chete inokonzera kana CPU imwe "iri nani" pane imwe. Inowanzoenderana nehuwandu hwemapurogiramu anotamba pamakombiyuta-mune mamwe mazwi, maitiro anenge ari kushandisa CPU.
Imwe CPU inogona kuva neawa yakadzika maawa asi iyo inonzi quad-core processor, asi imwe inenge yakakurumidza kumhanya kweawa asi inongova ye-double-core processor. Kusarudza kuti CPU ingapedzei imwe, zvakare, inodaro zvakakwana pane izvo CPU iri kushandiswa.
Semuenzaniso, chirongwa chekugadzira mavhidhiyo eC CPU- chinoshandiswa chinoshanda zvakakwana pane zvakawanda ma CPU cores zvichashanda zviri nani pamushandisi we-multicore neawa yakadzika maawa kupfuura zvaizoita pa-single-core CPU nepamusoro pemaawa. Kwete yose software, mitambo, nezvimwewo zvinogona kutora zvishoma pane imwe chete kana maviri mapepa, zvichiita kuti zvimwe zveCUU zvive zvisingabatsiri.
Chimwe chikamu cheCUU chiri cache. CPU cache yakafanana nekuchengetedza kwenguva pfupi yedhesi inowanzoshandiswa. Panzvimbo yekushevedza kusakanganwa kuchengetedza ( RAM ) yezvinhu izvi, CPU inosarudza kuti iwe unofunga kuti chii chaunoramba uchichishandisa, inofunga kuti iwe unoda kuramba uchiishandisa, uye unoichengeta mumudzidzi. Cache inokurumidza kudarika kushandisa RAM nokuti inhengo yepanyama yepurosesa; zvimwe cache zvinoreva nzvimbo yakawanda yekuchengetedza ruzivo rwakadaro.
Kunyangwe kombiyuta yako inogona kukwanisa 32-bit kana 64-bit operating system inotarisana nehukuru hwezvikwata zve data izvo CPU inogona kubata. Zvimwe zviyeuchidzo zvinogona kuwanikwa panguva imwechete uye muzvikamu zvakakura ne 64-bit processor kupfuura 32-bit rimwe, ndicho chikonzero kushandiswa kwezvirongwa uye zvidzidzo zviri 64-bit-zvakananga hazvikwanisi kumhanya pane 32-bit processor.
Iwe unogona kuona tsananguro ye CPU yemakombiyuta, pamwe chete nedzimwe ruzivo rwehutori, nehuwandu hwemashoko ehurongwa hwekushandisa .
Bhobho rimwe nerimwe raamai rinotsigira chete humwe huwandu hwemhando dzeCUU, saka kazhinji chengetedza nebhokisi rako rekipiki usati watenga kutenga. CPUs haisi nguva dzose yakakwana, nenzira. Nyaya iyi inotsvaga izvo zvingafamba zvisina kunaka navo .
