Konke malunga neCCU, iiCCC Cores, Speed Speed, kunye nezinye
I-unit central processing unit (CPU) yinkampani yekhompyutha ejongene nokutolika nokufezekisa imiyalelo emininzi yekhompyutha kunye nesofthiwe.
Zonke iintlobo zezixhobo zisebenzisa i-CPU, kubandakanywa ideskithophu, i-laptop, kunye nekhompyutheni, ii-smartphone ... nokuba isethi ye-screen-screen yithelevishini.
I-Intel kunye ne-AMD yilezi zibini ezidumileyo ze-CPU abenzi bee desktops, ii-laptops, kunye namaseva, ngelixa i-Apple, i-NVIDIA ne-Qualcomm zikhulu ze-smartphone kunye ne-tablet ye-CPU.
Unokubona amagama amaninzi ahlukeneyo asetyenziselwa ukuchaza i-CPU, kubandakanywa iprosesa, iprojekthi yecomputer, ipropyprocessor, iprosoft processor, kunye "nobuchopho bekhompyutha."
Iirekhodi zekhompyutheni okanye ii-drivers ezinzima ngamanye amaxesha zibhekwa ngokungafanelekanga njengeCPU, kodwa ezo zixhobo ze-hardware zenza iinjongo ezahlukeneyo kwaye azikho into efanayo ne-CPU.
Yiyiphi i-CPU ekhangeleka Njengaye kwaye i-# 39;
I-CPU yanamhlanje idla ngokuba yincinci kunye nekwere, kunye nezixhumi ezincinci, ezidibeneyo, ezinxibelelwano zetsimbi kwi-underside yayo. Amanye ama-CPU asele adala anezikhonkwane endaweni yezixhumo zetsimbi.
I-CPU ifake ngqo ngqo kwi-CPU "iscket" (okanye ngamanye amaxesha "i-slot") kwibhodi ye- motherboard . I-CPU ifakwe kwisiseko se-pin-side-down, kwaye i-lever encinci inceda ukukhusela inkqubo.
Emva kokusebenza ngethuba elifutshane, ii-CPU zanamuhla zitshisa kakhulu. Ukukunceda ukunqumla ukutshatyalaliswa kwaloo nto, kufuneka ukuba unqamle ukudibanisa isitshixo sokushisa kunye nomqhubi ngqo kwi-CPU. Ngokuqhelekileyo, ezi zinto ziza ukuthengwa nge-CPU yokuthenga.
Ezinye iinketho ezipholileyo zokupholisa nazo ziyafumaneka, kufaka phakathi iikiti zokupholisa amanzi kunye neeyunithi zokutshintshwa kwesigaba.
Njengoko kuchazwe ngasentla, akuyiyo yonke i-CPU enayo izikhonkwane kumacala awo, kodwa kulawo akwenzayo, izikhonkwane zilula. Yinyamekela xa usebenzisa, ngakumbi xa ufaka kwi-motherboard.
I-CPU Clock Speed
Ijubane lewashi leprojekti yile nombolo yemiyalelo engayenza kuyo nayiphi na into yesibini, ilinganiswe kwi-gigahertz (GHz).
Umzekelo, i-CPU inesivinini se-clock ye-1 Hz ukuba ingaqwalasela isiqwengatha esinye sesibini nganye. Ukuphucula oku kumzekelo wehlabathi wangempela: i-CPU enejubane le-3.0 GHz inokuyilungisa imiyalelo yeebhiliyoni ezi-3 ngesibini.
CoU Cores
Ezinye iiprojekti zinomprojekti omnye-mqobo ngelixa abanye banokuba ne-core-core (okanye i-quad-core, njl.). Njengoko kusenokuba sele kubonakala ukuba, ukuba neeyunithi ezimbini zeprojekithi zisebenza ngecala lithetha ukuba i-CPU ingakwazi ukulawula ngokuphindwe kabini imiyalelo yonke yesibini, ukuphucula ngokukodwa ukusebenza.
Ezinye i-CPU ziyakwazi ukulungelelanisa iibhola ezimbini kuzo zonke izinto ezisemzimbeni ezikhoyo, ezaziwa ngokuba yi-Hyper-Threading. Ukutshintshela kuthetha ukuba i-CPU eneentsimbi ezine kuphela ezinokusebenza njengokuba zinezibhozo ezisibhozo, kunye neeyongezelelo ze-CPU ezongezelelweyo ezibhekiswe njengezingcingo ezihlukeneyo. Iimpawu zomzimba , nangona kunjalo, zenza ngcono kunezinto ezibonakalayo .
I-CPU ikuvumela, ezinye izicelo zingasebenzisa oko kubizwa ngokuba yi- multithreading . Ukuba umgca uqondwa njengento enye yenkqubo yekhomputha, ukusetyenziswa kwemicu emininzi kwikomkhulu enye yeCCU kuthetha imiyalelo emininzi ingacaciswa kwaye iqhutywe kwangoko. Elinye isofthiwe inokuyisebenzisa ngokunxulumene nale nxalenye kwi-core CPU engundoqo, oko kuthetha ukuba imiyalelo eninzi ingaqwalaselwa ngokukodwa.
Umzekelo: Intel Core i3 vs. i5 vs. i7
Ngokomzekelo othe ngqo wendlela amanye ama-CPU ahambelana ngayo nabanye, makhe sijonge indlela i-Intel eyenze ngayo abaprofeti bayo.
Njengoko unokubakhokrola kwigama labo, i-Intel Core i7 chips yenza ngcono kune-i5 chips, ezenza ngcono kunezi-chips ze -3. Kutheni umntu enza ngcono okanye embi kunokuba abanye kunzima kakhulu kodwa ke kulula ukuyiqonda.
Iprojekthi ze-Intel Core i3 zi-processors-core, ngelixa i-i5 ne-7 chips ziyi-quad-core.
I-Turbo Boost yinto ebonakalayo kwi-i5 kunye ne-7 chips ezenza iprojekthi ikhulise i-speed clock yayo inqamle isantya sayo sesiseko, ukususela kwi-3.0 GHz ukuya kwi-3.5 GHz, nanini na kufuneka. I-Intel Core i3 chips ayinayo le meko. Iimodeli zeprojekithi eziphela "K" zinokugqithiswa , oko kuthetha ukuba le jubane leeyure elongezelelweyo linokunyanzeliswa kwaye lisetyenziswe lonke ixesha.
I-Hyper-Threading, njengoko kuchazwe ngasentla, yenza ukuba imicu emibili iqhutywe nganye kwinkqubo nganye yeCCU. Oku kuthetha abaprofeti be-i3 kunye ne-Hyper-Threading inkxaso kuphela ezine intambo ezixeshanye (kuba zibanjwe ngabaqhubi be-core-core). Intel Core i5 abaproseshi abaxhasi i-Hyper-Threading, oku kuthetha ukuba, nabo, banokusebenza kunye nemicu emine ngexesha elinye. I-processors i7, nangona kunjalo, bayayixhasa le teknoloji, ngoko ke (ukuba yi-quad-core) inokucwangcisa iintambo ezili-8 ngexesha elinye.
Ngenxa yeengxaki zendalo ezivela kumacebo angenayo ukunikezwa kwamandla okuqhubekayo (iimveliso ezibhekiselwe ibhetri ezifana nezixhobo ze-smartphones, iipilisi, njl.), Abaproseshi-kungakhathaliseki ukuba i-i3, i5, okanye i7-ihluke kwi desktop Ii-CPUs ukuba kufuneka zifumane ukulinganisela phakathi kokusebenza kunye nokusetyenziswa kwamandla.
Ulwazi olungakumbi kwiCCUs
Ijubane le-clock, okanye nje inani le-CPU, iyona nto yodwa ebonisa ukuba i-CPU enye "ingcono" kunomnye. Ngokuqhelekileyo kuxhomekeke kuninzi kwi-software eyenza ikhompyutha-ngamanye amagama, izicelo eziza kusebenzisa i-CPU.
I-CPU enye inokuba nejubane le-clock ephantsi kodwa iprogram yecad-core, ngelixa elinye linesivinini se-clock ephezulu kodwa kuphela yinkqubo engundoqo yenkqubo. Ukugqiba ukuba yiyiphi i-CPU eya kuphelisa enye, kwakhona, kuxhomekeke ngokupheleleyo kwi-CPU esetyenziswayo.
Umzekelo, inkqubo yokulungiswa kwevidiyo ye-CPU efuna ukusebenza kakuhle kwiinkqubo ezininzi ze-CPU iya kusebenza kangcono kumprosesa we-multicore ngexabiso elide le-clock kunokuba liza ku-CPU eyodwa kunye neyure ephakamileyo. Ayikho yonke i-software, imidlalo, njalonjalo inokusebenzisa ngokuninzi ngaphezu kweyodwa okanye ezimbini zokubamba, okwenza ezinye iikhowudi ze-CPU zifumaneke zingenamsebenzi.
Elinye iqela le-CPU ligciniwe. I-CPU cache ifana nendawo yokubamba yesikhashana idata esetyenziswa rhoqo. Esikhundleni sokubiza imemori yokungena ngokungahambiyo ( RAM ) yezi zinto, i-CPU inquma ukuba yiyiphi idatha ebonakala uqhubeka ukuyisebenzisa, ithatha ukuba ufuna ukuqhubeka ukuyisebenzisa, kwaye uyigcine kwindawo yokugcina. I-Cache ikhawuleza kunokuba isebenzise i-RAM ngoba inxalenye yenyama yomprosesa; I-cache enye ithetha indawo ephezulu yokugcina olo lwazi.
Ingaba ikhomputer yakho inokuqhuba i- 32-bit okanye i-64-bit yokusebenza kwinkqubo kuxhomekeke kubukhulu beeyunithi zeedatha ezikwazi ukuphatha i-CPU. Imemori engaphezulu ingafumaneka ngokukhawuleza kunye kunye neprogram engama-64-bit, ibe yintoni eyenza iinkqubo zokusebenza kunye nama- 64-bit-specific asebenze kwi-processor 32-bit.
Uyakwazi ukubona iinkcukacha zekhompyutheni zekhompyutha, kunye nolunye ulwazi lwe-hardware, kunye nezixhobo ezininzi zonxibelelwano zesistim .
I-motherboard nganye isekela kuphela uhlobo oluthile lwezixhobo ze-CPU, ngoko rhoqo qhasela umenzi wakho webhodi lebhodi ngaphambi kokuthenga. Ii-CPU azihlali zigqibeleleyo, ngendlela. Eli nqaku liphonononga oko kungahambi kakubi nabo .
