Wonke ama-CPUs, ama-CPU Cores, i-Clock Speed, nokuningi
I-central processing unit (CPU) yinkampani yekhompiyutha enesibopho sokuhumusha nokwenza imiyalo eminingi kusuka kwezinye izinto zekhompyutha kanye nesofthiwe.
Zonke izinhlobo zamadivaysi zisebenzisa i-CPU, kufaka phakathi ideskithophu, i-laptop, namakhompyutha we- tablet , ama-smartphone ... ngisho nesethi yethelevishini yakho yesikrini.
I-Intel ne-AMD yilabo abakhiqizi be-CPU abadume kakhulu kuma-desktops, ama-laptops, namaseva, kuyilapho i-Apple, i-NVIDIA, ne-Qualcomm yizinkampani ezinkulu ze-smartphone ne-tablet CPU.
Ungabona amagama amaningi ahlukene asetshenziselwa ukuchaza i-CPU, kufaka phakathi iprosesa, inqubo yekhompyutheni, i-microprocessor, iphrosesa ephakathi, kanye "nobuchopho bekhompyutha."
Amakhompiyutha noma ama- hard drives ngezinye izikhathi abizwa ngokungalungile njenge-CPU, kodwa lezo zicucu ze-hardware zisebenza ngezinhloso ezifani ngokuphelele futhi azikho into efanayo ne-CPU.
Yeka ukuthi i-CPU ibukeka kanjani nokuthi ikhona kuphi & # 39; s
I-CPU yesimanje ngokuvamile iyingcosana nesigcawu, enezixhumanisi eziningi ezincane, ezihlangene, zensimbi ezingaphansi kwayo. Amanye ama-CPU asekhulile anezikhonkwane esikhundleni sezixhumanisi zensimbi.
I-CPU ifaka ngqo ku-CPU "isikhwama" (noma ngezinye izikhathi "slot") ebhodini le- motherboard . I-CPU ifakwe ngaphakathi kwe-pin-side-down, futhi i-lever encane isiza ukuvikela iphrosesa.
Ngemuva kokusebenza ngisho nesikhashana, ama-CPU anamuhla angashisa kakhulu. Ukuze usize ukuhlakaza lokhu kushisa, kudingeke njalo kudingeke ukuba unamathisele umshini wokushisa nomoya ngokuqondile phezulu kwe-CPU. Ngokujwayelekile, lezi ziza ukuthengwa nge-CPU yokuthenga.
Ezinye izinketho zokuphefumula ezithuthukisiwe nazo ziyatholakala, kufaka phakathi izinkinobho zokupholisa amanzi kanye nezinyathelo zokushintsha kwesigaba.
Njengoba kukhonjisiwe ngenhla, akuwona wonke ama-CPU anayo izikhonkwane ezinhlangothini zawo ezingezansi, kodwa kulabo abenzayo, izikhonkwane ziboshelwa kalula. Nakekela kahle lapho uphatha, ikakhulukazi uma ufaka kwi-motherboard.
I-CPU Clock Speed
Ijubane lewashi leprosesa yinombolo yemiyalelo engakwazi ukuyisebenzisa kunoma yisiphi isibili esinikeziwe, kulinganiswa ku-gigahertz (GHz).
Isibonelo, i-CPU inejubane lewashi le-1 Hz uma lingakwazi ukucubungula isiqeshana esisodwa semfundo njalo ngomzuzwana. Ukwengeza lokhu kusibonelo somhlaba wangempela: i-CPU enejubane le-3.0 GHz lingakwazi ukucubungula iziyalezo eziyizigidi eziyi-3 ngomzuzwana ngamunye.
Amakhodi we-CPU
Amanye amadivayisi aneprosesa eyodwa-core ngenkathi abanye bangase babe ne-double-core (noma i-quad-core, njll.). Njengoba kungenzeka ukuthi sekuvele kubonakala, ukuba nama-processor amabili asebenza ngokubambisana kusho ukuthi i-CPU ingakwazi ukuphatha ngokuphindaphindiwe imiyalo kabili, isithuthukisa kakhulu ukusebenza.
Amanye ama-CPU angakwazi ukufeza ama-cores amabili kuwo wonke umuntu oyedwa ongokwenyama otholakala, owaziwa njenge-Hyper-Threading. Ukubukeka kahle kusho ukuthi i-CPU enezingqimba ezine kuphela ingasebenza njengokuthi inezinhlamvu eziyisishiyagalombili, kanti amanye amakhodi we-CPU engeziwe ayibhekwa njengezintambo ezihlukile. Ama-body cores, enza, angcono kunama- virtual .
I-CPU evumela, ezinye izinhlelo zokusebenza zingasebenzisa okuthiwa i- multithreading . Uma intambo iqondwa njengengxenye eyodwa yenqubo yekhompiyutha, besebenzisa izintambo eziningi kumuntu oyedwa we-CPU kusho ukuthi imiyalo eminingi ingaqondwa futhi isetshenziswe ngesikhathi esisodwa. Elinye isofthiwe lingasebenzisa lesi sici kumgqa ongaphezu kweyodwa we-CPU, okusho ukuthi imiyalo engaphezulu ingacutshungulwa kanyekanye.
Isibonelo: I-Intel Core i3 vs. i5 vs. i7
Ukuze uthole isibonelo esithile esithile sokuthi amanye ama-CPU asheshe kangakanani kunabanye, ake sibheke ukuthi i-Intel ikhiphe kanjani abacubungulayo.
Njengoba nje uzosolwa ngokuqamba igama, i-Intel Core i7 chips yenza kangcono kune-i5 chips, eyenza ngcono kunezingu-i3. Kungani umuntu enza okungcono noma okubi kunabanye kunzima kakhulu kodwa kusengcono kakhulu ukuyiqonda.
I-Intel Core iprosesa ye-i3 yi-processor core, kuyilapho i-i5 ne-i7 chips kuyi-quad-core.
I-Turbo Boost iyingxenye ye-i5 ne-i7 chips eyenza iprosesa yanda isivinini sayo sewashi sidlule isivinini sayo sesisekelo, njengokusuka ku-3.0 GHz kuya ku-3.5 GHz, noma kunini lapho kudingeka khona. I-Intel Core i3 chips ayinayo lekhono. Amamodeli weprosesa agcina ku-"K" angafakwa ngaphezulu , okusho ukuthi isivinini sewashi esengeziwe singaphoqelelwa futhi sisetshenziswe ngaso sonke isikhathi.
I-Hyper-Threading, njengoba kushiwo ngaphambili, yenza izintambo ezimbili zicutshungulwe ngomgomo ngamunye we-CPU. Lokhu kusho amaprosesa we-i3 nge-Hyper-Threading ukwesekwa kuphela izintambo ezine ngesikhathi esisodwa (njengoba ziyizicubungula ezimbili). Ama-processors e-Intel Core i5 awasekeli i-Hyper-Threading, okusho nokuthi nabo bangasebenza ngezintambo ezine ngesikhathi esifanayo. I-processors ye-i7, noma kunjalo, isekela lobu buchwepheshe, ngakho-ke (kuba yi-quad-core) ingahlela izintambo ezingu-8 ngesikhathi esifanayo.
Ngenxa yenkinga yamandla ekhona kumadivayisi angenawo amandla okuqhubekayo (imikhiqizo enikwe ibhethri efana ne-Smartphones, amaphilisi, njll), abaproseshi babo-kungakhathaliseki ukuthi i-i3, i5, noma i-i7-ihluke kusuka kwideskithophu Ama-CPU ukuthi kufanele athole ibhalansi phakathi kokusebenza nokusetshenziswa kwamandla.
Ulwazi Oluthe xaxa kuma-CPU
Isivinini se-clock, noma nje inani lezinhlamvu ze-CPU, yiyona nto kuphela ekhomba ukuthi i-CPU eyodwa "ingcono" kunomunye. Ngokuvamile kuxhomeke kakhulu kunhlobo lwe-software egijima kukhompyutha-ngamanye amagama, izinhlelo zokusebenza ezizosebenzisa i-CPU.
I-CPU eyodwa ingaba nesivinini sewashi esincane kodwa isishukela se-quad-core, kanti omunye unesisindo sewashi eliphezulu kodwa kuphela yiprosesa yombili. Ukunquma ukuthi yiliphi i-CPU elizokhipha elinye, futhi, lixhomeke ngokuphelele kulokho okusetshenziselwa i-CPU.
Isibonelo, uhlelo lokuhlela ividiyo oludinga i-CPU olusebenza kahle kuma-CPU amaningi luzosebenza kangcono kumprosesa we-multicore ngejubane eliphansi lewashi kunokuba liqhubeke ne-CPU eyodwa-core enejubane eliphezulu. Akuwona wonke ama-software, amageyimu nokunye okunjalo angasebenzisa okungaphezu kwekhamera elilodwa noma amabili, okwenza noma yiziphi izinhlamvu ze-CPU ezitholakalayo ezingenalusizo.
Enye ingxenye ye-CPU isilondolozi. I-CPU isilondolozi sinjengendawo yokugcina isikhashana yedatha evame ukusetshenziswa. Esikhundleni sokubiza imemori yokufinyelela okungahleliwe ( RAM ) yalezi zinto, i-CPU inquma ukuthi iyiphi idatha obonakala uyayisebenzisa, ithatha ukuthi uzofuna ukuqhubeka uyisebenzisa, bese uyigcina emcimbini. I-Cache iyashesha kunokusebenzisa i-RAM ngoba iyinxenye engokwenyama yeprosesa; I-cache eningi isho isikhala esiningi sokubamba lolo lwazi.
Kungakhathaliseki ukuthi ikhompyutha yakho ingaqhuba uhlelo lwe- 32-bit noma uhlelo lwe -64-bit yokusebenza lugxile kubukhulu bezinyunithi zedatha ukuthi i-CPU ingayisingatha. Inkumbulo engaphezulu ingafinyelelwa ngesikhathi esisodwa nangaphansi kwezicucu ezinkulu nangeprosesa engu-64-bit kune-32-bit eyodwa, yingakho izinhlelo zokusebenza nezinhlelo zokusebenza ezinama- 64-bit azikwazi ukugijima ku-proxy 32-bit.
Ungabona imininingwane ye-CPU yekhompyutha, kanye nolunye ulwazi lwe-hardware, ngamathuluzi amaningi olwazi lwedatha yamahhala .
I-motherboard ngayinye isekela uhlobo oluthile lwezinhlobo ze-CPU, ngakho-ke hlola njalo nomkhiqizi wakho we-motherboard ngaphambi kokuthenga. Ama-CPU awahlali ephelele, ngendlela. Lesi sihloko sihlola ukuthi yini engase ihambe kabi nabo .
