La Ikhadi lemifanekiso Lelinye lamacandelo asisiseko kuyo nayiphi na ikhompyuter, ngakumbi kwimeko yezixhobo ezilungiselelwe iGaming. Kule post siza kuzama ukuchaza athini kanye kanye lamakhadi, yeyiphi imisebenzi abayenzayo kwaye zingaphi iintlobo zazo ezahlukeneyo ezikhoyo.
Ngamanye amazwi, kwaye njengoko igama layo libonisa, yinto enikezelwe kwi ukusetyenzwa kwedatha enxulumene nevidiyo kunye nemifanekiso. Yonke into esiyibonayo kwiscreen lulwazi oluye lwenziwa leli khadi ukwenza ukuba saziwe kuthi.
Ngokwenyani, ikhadi lemizobo (ekwabizwa ngokuba yikhadi levidiyo) kukwandiswa kwebhodi yomama yekhompyuter. Umsebenzi wayo uqulathe qhubekisa idatha ethunyelwe yi-GPU yekhompyuter, uyiguqule ibe lulwazi olubonakalayo kwaye uyinikeze kwimonitha.
Kuba la makhadi aneyunithi yawo yokusetyenzwa, okanye i-GPU, igama elifanayo lihlala lisetyenziswa ukubhekisa kuwo, nangona oku kubhida ngandlel’ ithile. Ikhadi lemizobo ikwabizwa ngokuba yi-adaptha yokubonisa, iadaptha yevidiyo okanye ikhadi, kunye nekhadi le-accelerator yemizobo.
Ubume bekhadi lemizobo
Zeziphi izinto ezenza ikhadi lemizobo? Izinto ezintathu eziphambili yi-GPU, imemori ye-GRAM kunye ne-RMDAC, esiyichaza ngezantsi:
GPU
Inxalenye ephambili, njengoko besitshilo ngaphambili, yi GPU o Iyunithi yokulungisa imizobo. Yinkqubo entsonkothileyo yokujikeleza kunye nezigidi zeetshiphusi ezincinci, kunye neecores ezininzi ezinamandla okusebenza ngokuzimeleyo, ezinikezelwe ikakhulu kwi-vertex kunye nokusetyenzwa kwepixel. Okukhona zinamandla ngakumbi nangakumbi, kokukhona umgangatho womfanekiso oveliswa likhadi lemizobo ungcono.
inkumbulo yegram
Enye into esisiseko kula makhadi yi inkumbulo yegram (IMemori yoFikelelo ngokuKhethekileyo), ekhawulezisa inkqubo yokugcina nokuhambisa idatha.
I-RAMDAC
Ikwabalulekile I-RAMDAC, imemori yofikelelo olungenamkhethe lwedijithali ukuya kwi-analog converter. Eli candelo liyi-converter eneneni esetyenziselwa ukuhamba ukusuka kwisignali yedijithali ukuya kwisignali ye-analog. Umsebenzi osisiseko wekhadi.
Ukongeza kula macandelo mathathu aphambili, kufuneka sikhankanye iifeni okanye izitsini zobushushu, iyimfuneko ukuze ikhadi lemizobo lingatshisi ngokugqithisileyo ngelixa silisebenzisa kakhulu, njengokuba sichitha iiyure kunye neeyure nomdlalo.
I sebenza njani
Ukuyichaza ngendlela edibeneyo, izigaba ezibini zinokuchongwa ngaphakathi kokusebenza kwekhadi lemizobo:
- ukusetyenzwa kwevertex, equka ukufumana ulwazi lwe-vertex olubalwe yi-CPU. Kwakhona ulungelelwaniso lwayo lwesithuba, ukujikeleza kwayo, kunye nomsebenzi wokumisela ukuba yeyiphi kwezi zinto eza kubonakala ngokomzobo.
- ukuqhubekeka kwe-pixel, okanye ukuboniswa okubonakalayo kwayo yonke le nkqubo kwimonitha yekhompyuter yethu.
Ekugqibeleni, kufuneka kukhankanywe ukuba uxhulumaniso phakathi kwekhadi lemizobo kunye ne-monitor ingaba neentlobo ezahlukeneyo (i-DVI, i-VGA, i-HDMI, i-DisplayPort okanye i-USB-C), nganye ineempawu zayo.
Iintlobo zekhadi lemizobo
Nje ukuba siyazi ukuba yintoni kwaye isebenza njani, umbuzo omkhulu uyeza: Leliphi ikhadi lemizobo ukukhetha? Impendulo iya kuxhomekeka ekubeni kukuphi ukusetyenziswa okuqhelekileyo esiza kukunika ikhompyuter yethu. Ukusetyenziswa okuqhelekileyo, ngaphandle kweemfuno ezinkulu, naliphi na ikhadi elisisiseko liya kwenza; Kwelinye icala, ukuba siza kunikezela ngePC yethu kumdlalo, kuya kufuneka sifake ikhadi lemizobo elinamandla.
Kufuneka kutshiwo ukuba amakhadi egraphics awasebenzi nje ukufumana amava angcono ngemidlalo yevidiyo, aya kusinceda nathi ukwenziwa kweefoto, oopopayi okanye iiprojekthi zesiqulatho sedijithali, Umzekelo. Bade bakhonze Iimali zedijithali zam.
Kodwa xa i-push isiza ukutyhala, umbuzo ubuyela kukhetho olulula phakathi kweebrendi ezimbini ezinkulu: NVIDIA okanye AMD.
NVIDIA
Amakhadi emizobo enziwe yi-NVIDIA awona athengiswa kakhulu kwihlabathi liphela. La makhadi anayo Itekhnoloji yeDLSS, evumela ukuba kusetyenziswe amandla othungelwano olunzulu lwe-neural network, ngaloo ndlela ukwandisa umlinganiselo wesakhelo kunye nokufezekisa ukuphuculwa okuphawulekayo kumgangatho womfanekiso.
AMD
Kwicala labo, amakhadi e-AMD eza nobuchwepheshe Imemori yokuFikelela ye-AMD apho uphuculo olukhulu ekusebenzeni kwemidlalo luphunyezwa ngenxa yonxibelelwano olumanzi ngakumbi phakathi kweeprosesa zeRyzen kunye namakhadi emizobo yeRadeon.
Nokuba sikhetha ntoni na, into ebalulekileyo ekufuneka siyiqwalasele kukuba zombini isisombululo kunye nesantya sohlaziyo sekhompyuter yethu siyahambelana nomgangatho kunye namandla ekhadi lemizobo esiza kulifaka. Kunokuthiwa okufanayo malunga ne-CPU kunye ne-RAM yezixhobo zethu.
Kwaye sele sithetha ngamaxabiso, zombini enye kunye nolunye uhlobo lubonelela ngoluhlu olubanzi lweemodeli ezinamaxabiso ukusuka ngaphantsi kwe-300 euro ukuya ngaphezulu kwe-euro eyi-1.000.
