Ikhadi levidyo

Imemori yevidiyo ingenye yezici ezibaluleke kakhulu zekhadi levidyo. Inethonya elinamandla kakhulu ekusebenzeni jikelele, ikhwalithi yesithombe sokukhishwa, isinqumo sayo, futhi ngokuyinhloko ekudluleni kwekhadi levidiyo, ozofunda ngakho ngokufunda lesi sihloko. Funda futhi: Iprosesa ithinta kanjani emidlalweni? Imiphumela yemvamisa yememori yevidiyo

Ukuthuthukiswa nokukhiqizwa kwezinto zokuqala ze-video amakhadi kuyaziwa ezinkampanini eziningi AMD kanye ne-NVIDIA, kodwa ingxenye encane ye-accelerators yama-graphics evela kulabo abakhiqizi bangena emakethe enkulu. Ezimweni eziningi, izinkampani zomlingani, ezishintsha ukubukeka neminye imininingwane yamakhadi njengoba zibona kufanelekile, faka umsebenzi.

Uma usebenzisa ikhadi levidiyo, singase sibhekane nezinkinga eziningi nezinkinga, okunye okungukuthi kukhona idivayisi kuMphathi weDivaysi yeWindows. Ngokuvamile, ukuhluleka okunjalo kuphawulwa uma kunezici ezimbili ze-ihluzo ze-ihluzo ohlelweni - oludidiyelwe nolungaqondakali. Kuphela kokugcina futhi "kunganyamalala" ohlwini lwamadivayisi atholakalayo.

Ezweni lanamuhla, abaningi baye bazwa ngomqondo onjalo njengekhadi levidiyo. Abasebenzisi abanolwazi kakhulu bangase bazibuze ukuthi kuyini nokuthi kungani udinga le divayisi. Omunye angase angathinti ukubaluleka kweGPU, kodwa ngeze. Uzofunda ngokubaluleka kwekhadi levidiyo kanye nemisebenzi eyenziwa ngezinqubo ezithile kulesi sihloko.

Ukubuyekeza abashayeli bekhadi lehluzo le-NVIDIA ngokuzithandela futhi akudingeki njalo, kodwa ngokukhululwa kwezinguqulo ezintsha ze-software, singathola "amabhuzu" engeziwe engeziwe ngendlela yokuthuthukisa kangcono, ukusebenza okwenyuka kwamanye imidlalo kanye nezinhlelo zokusebenza. Ngaphezu kwalokho, izinguqulo ezintsha zilungisa amaphutha ahlukahlukene kanye nokungaphumeleli kukhodi.

Ikhadi levidiyo yidivayisi eyinkimbinkimbi edinga ukuhambisana ngokugcwele nehadiwe efakwe ne-software. Ngezinye izikhathi i-adapters inezinkinga ezenza kube nzima ukuzisebenzisa. Kulesi sihloko sizokhuluma ngekhodi yephutha 43 nokuthi singalungiswa kanjani.

Njengomthetho, izibuyekezo zesofthiwe yesistimu yeprosesa yehluzo ziletha ukuthuthukiswa komsebenzi nokusekela ubuchwepheshe obusha. Ngezinye izikhathi, kunomphumela ohlukile: emva kokuvuselelwa komshayeli, ikhompyutha iqala ukusebenza kakhulu. Ake sibone ukuthi kungani lokhu kwenzeka, nokuthi ungalungisa kanjani lolu hlobo lokuhluleka.

Ngokuhamba kwesikhathi ekuphileni kwakho konke ikhompyutha kuza isikhathi sokuthuthukisa okungenakugwemeka. Lokhu kusho ukuthi kudingekile ukufaka esikhundleni sezingxenye zakudala ngezinguquko ezintsha, ezanamuhla. Abasebenzisi abaningi besaba ukuzimela ngokuzimela ekufakweni kwensimbi. Kulesi sihloko sizobonisa, sisebenzisa isibonelo sokunqamula ikhadi levidyo kusuka ebhodini le-motherboard, ukuthi akukho lutho olungalungile ngalokhu.

Uma ubheka izici ze-laptops, ungavame ukukhubeka kwi-value "ehlangene" ensimini ukuze ubonise uhlobo lwekhadi levidyo. Kulesi sihloko sizobheka ngokucophelela lokho okubizwa ngokuthi ihluzo ezihlanganisiwe, ukuthi yikuphi, nezinye izinto ezihlobene nesihloko se-chips ehlanganisiwe.

Emidlalweni, ikhadi levidiyo lisebenza ngokusebenzisa inani elithile lezinsiza zalo, okukuvumela ukuba uthole i-FPS ephezulu kakhulu neyikhululekile. Nokho, ngezinye izikhathi i-adapter ihluzo ayisebenzisi wonke amandla, ngenxa yokuthi umdlalo uqala ukunciphisa futhi ubushelelezi ulahlekile. Sinikeza izixazululo eziningana kule nkinga.

Ikhompuyutha yesimanje, uma iqhathaniswa nabalingani bayo asebekhulile, iyisetshenziswa esiphezulu esinamandla kakhulu. Ukukhiqizwa kwensimbi yeselula kukhula nsuku zonke, okudinga amandla amaningi. Ukugcina amandla webhethri, abakhiqizi bafaka amakhadi amabili evidyo kuma-laptops: owakhelwe ngaphakathi kwebhodi le-motherboard futhi enesisetshenziswa samandla aphansi, futhi okwesibini okungaqondakali, okunamandla kakhulu.

Uma ufunda ulwazi mayelana nezinsimbi zamakhompiyutha, ungakhuthaza into enjengekhadi levidyo le-discrete. Kulesi sihloko sizobheka ukuthi iyiphi ividyo lekhadi elidumile nokuthi lisinikeza yona. Izici zekhadi levidiyo elingaqondakali Ikhadi levidiyo elingaqondakali liyidivaysi ezayo njengengxenye ehlukile, okungukuthi, ingasuswa ngaphandle kokuthinta lonke i-PC.

Uma uqala ukuqaphela ukuthi umsindo owenziwe ngenkathi ikhompyutha isebenzayo, sekuyisikhathi sokugcoba ipholile. Ngokuvamile ukukhala nokukhala okukhulu kubonakala kuphela phakathi kwemizuzu yokuqala yesistimu, khona-ke i-lubricant ivuselela ngenxa yokushisa futhi isondliwe ekuthwaleni, ukunciphisa ukungqubuzana. Kulesi sihloko sizobheka inqubo yokugcoba kwe-cooler ekhadini levidiyo.

Ngokuhamba kwesikhathi, waqala ukubona ukuthi izinga lokushisa kwekhadi legrafu laliphakeme kakhulu kunemva kokuthenga. Abalandeli bokupholisa bajikeleza ngokugcwele amandla, bexosha futhi bebole esikrinini. Lokhu kuyashisa. Ukushisa kakhulu kwekhadi levidiyo kuyinkinga enkulu kakhulu. Ukushisa okukhulayo kungaholela ekuvuseleleni okuqhubekayo ngesikhathi sokusebenza, kanye nokulimala kudivayisi.

Eminyakeni embalwa edlule, i-AMD ne-NVIDIA bathule ubuchwepheshe obusha kubasebenzisi. Enkampanini yokuqala, ibizwa nge-Crossfire, futhi kwesibili - SLI. Lesi sici sikuvumela ukuthi uxhumanise ama-video amabili wevidiyo ukuze wenze ukusebenza okuphezulu, okungukuthi, bazocubungula isithombe esisodwa ndawonye, ​​futhi ngombono, sebenze kabili ngokukhawuleza njengekhadi elilodwa.

Ngezinye izikhathi, ngesikhathi sokushisa okude isikhathi eside, amakhadi evidyo aqhutshelwa ukuqhutshwa kwe-chip video noma imemori yezinkumbulo. Ngenxa yalokhu, kunezinkinga ezihlukahlukene, kusukela ekubukeni kwezinto zokusebenza kanye nemigoqo yemibala esikrinini, ekupheleni kokungabikho okuphelele kwesithombe. Ukulungisa le nkinga, kungcono ukuxhumana nesikhungo sesevisi, kodwa okuthile kungenziwa ngezandla zakho.

I-grease yama-thermal (isikhombisi esibonakalayo esishisayo) yinto ehlukahlukene eyenzelwe ukuthuthukisa ukudluliswa kwe-heat kusuka ku-chip kuya ku-radiator. Umphumela utholakala ngokugcwalisa ukungalungi ezindaweni zombili zombili, okukhona okudala izikhala zomoya ngokumelana nokushisa okuphezulu, ngakho-ke ukuqhuba okuphansi kwe-thermal.

Uhlobo lwememori yevidiyo olufakwe ku-adapter yehluzo okungenani kunquma izinga lokusebenza kwalo, kanye nenani lomakhi ozolibeka emakethe. Ngemva kokufunda lesi sihloko, uzofunda ukuthi izinhlobo ezahlukene zememori yevidiyo zingahluka kanjani komunye nomunye. Sizokuthinta ngesikhashana isihloko senkumbulo ngokwayo kanye nendima yayo emsebenzini we-GPU, futhi okubaluleke kakhulu, sizofunda ukuthi sibuke kanjani uhlobo lwenkumbulo efakwe ekhadini levidiyo ku-unit yakho yesistimu.

I-TDP (i-Thermal Design Power), futhi "nezidingo zokushisa okushisa" zesiRashiya, iyim parameter ebaluleke kakhulu okumelwe igcinwe engqondweni futhi uyibeke ngokucophelela lapho ukhetha ingxenye yekhompyutha. Iningi lawo wonke ugesi ku-PC lugqunywa yiprosesa ephakathi nendawo yokuhluza ihluzo, ngamanye amazwi, ikhadi levidyo.

Ngaphambilini, amakhadi wevidiyo ayexhunywe kumlindisi usebenzisa i-VGA video interface. Ukudluliswa kwesithombe kwenziwa nge-signal ye-analog ngaphandle kokukhipha umsindo. Ubuchwepheshe busungulwe ngendlela yokuthi izibukeli ze-VGA zingasebenza ngaphandle kwezinkinga ngezinguqulo ezintsha ze-adapters ezihlukumezayo ezisekela imibala eminingi.
