Phantse zonke iikhompyuter zixhotyiswe ngekhadi levidiyo eligqwethekileyo. Ngesixhobo, umfanekiso obonakalayo kwiscreen sokubeka esweni senziwe. Eli candelo likude kakhulu, kodwa liqulathe iinkcukacha ezininzi zokwenza inkqubo enye yokusebenza. Kweli nqaku siza kuzama ukuxelela iinkcukacha malunga nawo onke amacandelo eKhadi leVidiyo yanamhlanje.
Lithini ikhadi levidiyo
Namhlanje siza kuqwalasela amakhadi evidiyo yendala, kuba idityanisiwe inephakheji eyahlukileyo ngokupheleleyo kwaye, ubukhulu becala, zakhiwe kwiprosesa. I-adaptha yemizobo egqwethekileyo iboniswa njengeBhodi yeSiphako eprintiweyo, efakwe kwi-vezictoctoct efanelekileyo yokwandiswa. Onke amacandelo e-adaptha yevidiyo abekwe kwiBhodi ngokwawo ngendlela ethile. Masimangaliswe onke amalungu ahlanganisiweyo.Bona kwakho:

Ithetha ukuthini ikhadi levidiyo elihlanganisiweyo
Iprosesa yegraphic
Kwasekuqaleni, kuya kufuneka uthethe ngeyona nxalenye ibaluleke kakhulu kwikhadi levidiyo - i-GPU (iprojeksi yeMizobo). Isantya kunye namandla esixhobo sonke sixhomekeke kweli candelo. Ukusebenza kwayo kubandakanya ukuqhubekeka kwemizobo ehambelana nemizobo. Iprosesa yemizobo ithatha ukwenziwa kweentshukumo ezithile, ngenxa yoko umthwalo kwi-CPU uncitshiswa, ekhulula izixhobo zayo ngezinye iinjongo. Ikhadi levidiyo elingakumbi eliphakathi, amandla e-GPU efakwe kuyo inkulu, inokuthintela nakwiprosesa eyintloko ngenxa yobukho beebhloko ezininzi zokwenza ikhompyutha.
Umlawuli wevidiyo
Umlawuli wevidiyo unoxanduva lokuvelisa umfanekiso kwimemori. Ithumela imiyalelo kumguquli we-digital-ye-Digital-qhubela ukulungiswa kwemiyalelo ye-CPU. Kwikhadi lexesha lanamhlanje, eyakhelwe-ngokwakha izinto ezininzi: umlawuli wememori yevidiyo, ibhasi yedatha yangaphandle neyangaphakathi. Icandelo ngalinye lizimeleyo ngaphandle komnye nomnye, livumela ulawulo lwalo ngaxeshanye lwemiboniso.
Imemori yevidiyo
Ukugcina imifanekiso, imiyalelo kunye ne-Enterpt, isixa esithile sememori siyadingeka kwiscreen sezinto. Ke ngoko, kwi-adaptha nganye yeadapter kukho inani eliqhelekileyo lememori. Kwenzeka iintlobo ezahlukeneyo nezahlukileyo nesantya zabo rhoqo. Uhlobo lwe-GDDR5 okwangoku luthandwa kakhulu, lisetyenziswa kumakhadi amaninzi anamhlanje.
Nangona kunjalo, kukwakufanelekile ukuba uqaphele oko, ukongeza kwizixhobo ezitsha ezakhiwe kwikhadi levidiyo, ukusetyenziswa kwezixhobo ezitsha ukusetyenziswa kunye ne-RAM efakwe kwikhompyuter. Ukufikelela kuyo, umqhubi okhethekileyo usetyenziswa nge-PCIE kunye neBhasi ye-AGP.
I-Digital-ye-Analog yokuguqula
Umlawuli wevidiyo uvelisa umfanekiso, kodwa kufuneka aguqulwe abe ngumqondiso onqwenelekayo ngamanqanaba athile ombala. Le nkqubo yenza i-DAC. Yakhiwe ngohlobo lweebhloko ezine, ezintathu ezinoxanduva lwenguqu ye-RGB (ibomvu, iluhlaza kwaye iluhlaza), kwaye ibhloko yokugqibela igcina ulwazi malunga nokuqaqamba okuzayo kunye nolungiso oluzayo. Isitishi esinye sisebenza ngamanqanaba okukhanya angama-256 kwimibala nganye, kwaye kwinani le-DAC libonisa imibala yezigidi ye-16,7.
Inkumbulo esisigxina
I-ROM igcina izinto eziyimfuneko kwiscreen, ulwazi oluvela kwi-BIOOS kunye neetafile zenkqubo. Umlawuli wevidiyo awusebenzi kunye nesixhobo sokugcina rhoqo, isibongozo kuyo sivela kuphela kwi-CPU. Kuyibulela ngokugcinwa kolwazi kwikhadi levidiyo le-BioS liqala kwaye imisebenzi ide ilayishwe ngokupheleleyo.
Inkqubo yokupholisa
Njengoko uyazi, iprosesa kunye nekhadi lemifanekiso zezona zinto zishushu zekhompyuter, ke kufuneka njalo. Ukuba, kwimeko ye-CPU, i-Couler icwangcisiwe ngokwahlukeneyo, emva koko iredireyitha kunye nabalandeli abaliqela baphakanyiselwe uninzi lwamakhadi evidiyo, eyenza ukuba ikwazi ukugcina ubushushu obuphakathi kwimithwalo ephantsi. Amanye amakhadi athile anamandla ashushu, ngoko ke inkqubo yamanzi anamandla isetyenziselwa ukupholisa.

Ikhondino
Amakhadi emizobo yanamhlanje axhotyiswe ikakhulu yi-HDMI, DVI kwaye abonise isinxibelelanisi sePort. Ezi zinto zifunyanisiweyo zezona nkqubela phambili, ngokukhawuleza kwaye uzinzile. Elinye lala mazwi linezibonelelo zalo kunye nezinto ezingalunganga, onokwazi ukwazisa ngokweenkcukacha kumanqaku kwiwebhusayithi yethu.

Kweli nqaku, sihlanganisene ngokweenkcukacha isixhobo sekhadi levidiyo, ihlolwe ngokweenkcukacha icandelo ngalinye kwaye ifumene indima yayo kwisixhobo. Sinethemba lokuba ulwazi olunikiweyo luluncedo kwaye unokufunda into entsha.
