Cishe wonke amakhompyutha ahlome ngekhadi levidiyo e-discrete. Ngale divayisi, isithombe esibonakalayo esikrinini sokuqapha siyadalwa. Le ngxenye ayilula kakhulu, kepha iqukethe imininingwane eminingi eyakha uhlelo olulodwa lokusebenza. Kulesi sihloko sizozama ukusho ngokuningiliziwe mayelana nazo zonke izingxenye zekhadi levidiyo lanamuhla.
Yini ikhadi levidiyo
Namuhla sizobheka amakhadi wevidiyo wanamuhla, ngoba ahlanganisiwe anephakethe elihluke ngokuphelele futhi, ikakhulukazi, ayakhelwe kwiprosesa. I-adaptha ye-discrete i-adaptha yethulwe njengebhodi lokujikeleza eliphrintiwe, elifakwe kwisixhumi esifanele esifanele. Zonke izingxenye ze-adaptha yevidiyo zitholakala ebhodini uqobo nge-oda elithile. Ake sizibuze zonke izingxenye eziyinhlanganisela.Bona futhi:
Yini ikhadi levidiyo e-discrete
Kusho ukuthini ikhadi levidiyo elihlanganisiwe
Processor graphic
Ekuqaleni, udinga ukukhuluma ngengxenye ebaluleke kakhulu ekhadini levidiyo - GPU (iprosesa yehluzo). Ijubane namandla edivaysi yonke kuncike kule ngxenye. Ukusebenza kwayo kufaka phakathi ukucubungula imidwebo ehambisana nehluzo. Iprosesa yehluzo ithatha ukwenziwa kwezenzo ezithile, ngenxa yokuthi umthwalo we-CPU unciphisiwe, ukhulula izinsiza zawo kwezinye izinhloso. Ikhadi levidiyo lesimanjemanje, amandla e-GPU afakwe kuwo likhulu, lingadlula ngisho neprosesa eliphakathi ngenxa yokuba khona kwamabhulokhi amaningi wekhompyutha.
Isilawuli sevidiyo
Isilawuli sevidiyo sibhekele ukukhiqiza isithombe kwimemori. Ithumela imiyalo kwi-Digital-Analog Converter futhi yenze ukucutshungulwa kwemiyalo ye-CPU. Ekhadini lesimanje, ezakhelwe ngaphakathi ezingxenyeni eziningana: Isilawuli sememori yevidiyo, ibhasi langaphandle nelingaphakathi. Izakhi ngasinye zisebenza ngokuzimela komunye nomunye, kuvumela ukuphathwa kanyekanye kokuboniswa.
Inkumbulo yevidiyo
Ukugcina izithombe, imiyalo kanye nabaphakathi, inani elithile lememori liyadingeka esikrinini sezinto. Ngakho-ke, kwimidwebo ngayinye ye-adaptha kunememori engapheli. Kuyenzeka izinhlobo ezahlukene ezihlukile ngesivinini sazo nangemvamisa. Uhlobo lwe-GDDR5 okwamanje luthandwa kakhulu, olusetshenziswa emakhadini amaningi anamuhla.
Kodwa-ke, kufanelekile ukukubheka lokho, ngaphezu kwamadivayisi amasha akhelwe ekhadini levidiyo, ukusetshenziswa kwamadivayisi amasha kanye ne-RAM efakwe kukhompyutha. Ukufinyelela kuyo, kusetshenziswa umshayeli okhethekile nge-PCIE ne-AGP.
I-Digital-Analog Converter
Isilawuli sevidiyo sikhiqiza isithombe, kepha sidinga ukuguqulwa sigisele kwisiginali oyifunayo ngamazinga athile emibala. Le nqubo yenza i-DAC. Yakhelwe ngesimo samabhulokhi amane, ezintathu zazo ezibhekele ukuguqulwa kwe-RGB (ezibomvu, eziluhlaza okotshani kanye nohlaza okwesibhakabhaka), futhi ibhlokhi yokugcina igcina imininingwane ngokukhanya okuzayo kanye nokulungiswa kwe-gamut. Isiteshi esisodwa sisebenza ngamazinga wokukhanya angama-256 wemibala yomuntu ngamunye, kanye nesamba se-DAC sibonisa imibala engu-16.7 million.
Inkumbulo engapheli
I-ROM igcina izinto ezidingekayo zesikrini, imininingwane evela kuma-bios namatafula ohlelo. Isilawuli sevidiyo asisebenzi kanye nedivaysi yokugcina njalo, isikhalazo kuyokwenzeka kuphela kusuka ku-CPU. Sibonga ukugcinwa kwemininingwane ekhadini levidiyo ye-BIOS liqala futhi lisebenze kuze kube yilapho i-OS ilayishwe ngokuphelele.
Uhlelo lokupholisa
Njengoba wazi, i-processor ne-Graphics Card iyizakhi ezishisa kakhulu zekhompyutha, ngakho-ke ukupholisa kuyadingeka kubo. Uma, esimweni se-CPU, elipholile lisethwe ngokwahlukana, i-radiator kanye nabalandeli abaningana bafakwa emakhadini amaningi wevidiyo, okwenza kungenzeka ukuthi kugcinwe izinga lokushisa eliphansi emithanjeni esindayo. Amanye amakhadi anamuhla anamandla ashisa kakhulu, ngakho-ke kusetshenziswa uhlelo olunamandla lwamanzi ukuze lubaphonse.

Ukuxhumana kokuxhumeka
Amakhadi wehluzo wanamuhla ahlome kakhulu nge-HDMI eyodwa, i-DVI nesixhumi sePort port. Lokhu okutholakele kuthuthuka kakhulu, okusheshayo futhi okuzinzile. Ngayinye yalezi zinhlaka zezinzuzo nezinzuzo zayo kanye nokubi, lapho ungazi khona ngokuningiliziwe ezihlokweni zewebhusayithi yethu.

Kulesi sihloko, sihlangene ngokuningiliziwe idivaysi yekhadi levidiyo, ihlolwe ngemininingwane ngayinye futhi yathola indima yayo kudivayisi. Siyethemba ukuthi imininingwane enikeziwe yayiwusizo futhi ungafunda okuthile okusha.
