Emhlabeni wanamuhla, abaningi bezwe ngomqondo onjalo njengekhadi levidiyo. Abasebenzisi abangafundile kakhulu bangazibuza ukuthi kuyini nokuthi kungani le divayisi idingeka. Othile angeke anamathisele ukubaluleka kwe-GPU, kepha ngehluleka. Uzofunda ngokubaluleka kwekhadi levidiyo nemisebenzi eliyenzayo ezinhlelweni ezithile kulo mbhalo.
Kungani ngidinga ikhadi lemifanekiso
Amakhadi wevidiyo ayisixhumanisi phakathi komsebenzisi ne-PC. Adlulisa imininingwane eyenziwe yinkampani ye-computer ebhekise kuqapha, ngaleyo ndlela enza kube lula ukuxhumana phakathi komuntu nekhompyutha. Ngokungeziwe kokukhishwa kwesithombe okujwayelekile, le divayisi isebenza ngokusebenza nokusebenza kokuphathelene, kwezinye izikhathi, ilayisha iprosesa. Ake sibhekisise isenzo sekhadi levidiyo ezimeni ezahlukahlukene.
Indima eyinhloko yekhadi levidiyo
Uwubona umfanekiso esibonelweni sakho ngenxa yokuthi ikhadi levidiyo licubungula imininingwane ebonakalayo, wasiguqula saba ngamasignali evidiyo futhi wasikhombisa esibukweni. Amakhadi wegrafu wesimanje (i-GPUs) angamadivayisi azimele yedwa, ngakho-ke athulula i-RAM ne-processor (CPU) emisebenzini eyengeziwe. Kufanele kwaziwe ukuthi manje ama-adaptha wesithombe akuvumela ukuthi uxhume i-track usebenzisa i-interface eyahlukahlukene, ngakho-ke amadivayisi aguqula isiginali yohlobo lokuxhumana olusebenzayo.
Ukuxhuma nge-VGA kuya ngokuya kungasebenzi, futhi uma lesi sixhumanisi sisatholakala kumakhadi wevidiyo, asitholakali kumamodeli athile wokubheka. I-DVI idlulisela isithombe kangcono kancane, kepha ayikwazi ukuthola amasiginali womsindo, yingakho iphansi ekuxhumekeni nge-HDMI, ethuthukiswa nesizukulwane ngasinye. Isibonisi se-DisplayPort sithathwa njengethuthuka kakhulu, siyafana ne-HDMI, kepha sinesiteshi esibanzi sokudlulisa imininingwane. Esizeni sethu ungazijwayeza ukuqhathanisa nezindawo zokuxhumana ezixhumanisa umlingisi ekhadini levidiyo bese ukhetha eyodwa efanele wena.

Ngaphezu kwalokho, kufanelekile ukunaka ama-accelerators wehluzo ahlanganisiwe. Njengoba ziyingxenye yeprosesa, umqaphi uxhunywe kuphela ngezixhumi ezikwibhodi yomama. Futhi uma unekhadi le-discrete, bese uxhuma izikrini kuphela ngalo, ngakho-ke ngeke usebenzise umgogodla owakhelwe ngaphakathi futhi uthole ukusebenza okuningi.

Indima yekhadi levidiyo emidlalweni
Abasebenzisi abaningi bathenga amakhadi wezithombe ezinamandla kuphela ukusebenzisa imidlalo yesimanje. Iprosesa lehluzo linakekela imisebenzi eyisisekelo. Isibonelo, ukwakha ifreyimu ebonakalayo kumdlali, ukubeka ngamanani okungafani kwezinto ezibonakalayo, ukukhanyisa nokufaka ngemuva ngokungezwa kwemiphumela nokuhlunga kuyenziwa. Konke lokhu kuwela emandleni we-GPU, futhi i-CPU yenza ingxenye encane kuphela yayo yonke inqubo yokudala izithombe.

Kulokhu kuvela ukuthi ikhadi levidiyo linamandla ngokwengeziwe, ukucubungula ngokushesha imininingwane ebonakalayo ebonakalayo. Ukulungiswa okuphezulu, imininingwane kanye nezinye izilungiselelo zehluzo kudinga inani elikhulu lezinsiza nesikhathi sokusebenza. Ngakho-ke, enye yamapharamitha abaluleke kakhulu ekukhetheni inani lememori i-GPU. Ungafunda okuningi ngokukhetha ikhadi lomdlalo esihlokweni sethu.

I-Rumor inakho ukuthi ukumodela kwe-3D ezinhlelweni ezithile, kuyadingeka ikhadi elikhethekile lehluzo, isibonelo, uchungechunge lwe-Quadro oluvela eNvidia. Lokhu kuyiqiniso ngokwengxenye, umenzi ulolonge ngqo uchungechunge lwe-GPU ngemisebenzi ekhethekile, isibonelo, uchungechunge lwe-GTX lwenza kahle emidlalweni, futhi amakhompyutha akhethekile asuselwa kumaTesla GPU asetshenziswa ocwaningweni lwesayensi nobuchwepheshe.
Kodwa-ke, empeleni kuvela ukuthi ikhadi levidiyo alibandakanyeki ekucutshungweni kwezigcawu ze-3D, amamodeli nevidiyo. Amandla ayo asetshenziswa ngokuyinhloko ukudala izithombe kuwindo lokuqagela lomhleli - isibuko. Uma uhlanganyela ekuhleleni noma ekuhlolweni, sincoma ukuthi kuqala unake amandla we-processor nenani le-RAM.

Kulesi sihloko, sihlole kabanzi iqhaza lekhadi levidiyo ekhompyutheni, sikhulume ngezinhloso zalo emidlalweni nasezinhlelweni ezikhethekile. Le ngxenye yenza izenzo ezibalulekile, sibonga iGPU sithola isithombe esihle emidlalweni kanye nokukhonjiswa okuyikho kwengxenye yonke ebonakalayo yohlelo.
