Kungani ikhadi lifudumele?

Kwabanye abanikazi be-PC, isambulo sangempela yiqiniso lokuthi noma yiliphi ikhadi levidiyo elivuthayo, kokubili libala futhi lihlanganiswe ku-chipset noma i-CPU.

Kungani lokhu kwenzeka? Isizathu sini ikhadi elishisayo? Konke kuchazwa ngokucacile: i-adapter yezinsuku zanamuhla isekelwe kwiprosesa ehluzisayo ehlanganisa izigidi zokushintshwa kwe-electronic - abashintshi. Nakuba ukusetshenziswa kwalowo nalowo kuleso sikhohla, inani lalo lonke likhulu kakhulu.

Njengoba kuyaziwa esikoleni se-physics, lapho okwamanje kudlula umqhubi, izinga lokushisa lalezi zinsuku liyakhula. Umphumela uzwakala kakhulu emafrijini aphezulu, okuyikho emakhadini evidiyo. Lokhu kungagwenywa kuphela lapho ama-superconductors asetshenziselwa ngaso sonke isikhathi.

Ngakho-ke, uma ikhadi levidiyo livutha, lokhu akusho ukungasebenzi.

Noma kunjalo, emaforamu lesi sihloko sivame ukuphakanyiswa. Kungani isihloko sixoxwa kabanzi? Isizathu salokhu ukuthi ngezinye izikhathi ikhadi le-graphics lishisa kakhulu, elikhathaza umnikazi wekhompyutha.

Azikho izinkinga zama- CPU ezihlanganisiwe ku- CPU - izinhlelo zokupholisa ezikhulayo zanamuhla zichitha kalula i-W Wama-thermal angu-100 , okungaphezu kokwanele. Ngaphezu kwalokho, ukusebenza kwabo kuncane izikhathi eziningana kuneklasi elijwayelekile lama-adapters ahlaziyekile, ngakho-ke imvamisa yokusebenza kanye nenani labase-transistors akwanele ukudala umthwalo ophezulu owedlula ukusebenza kohlelo lokupholisa. Ngamanye amazwi, ngokuvamile iningi lekhadi levidyo lekhadi liyashisa , lixhunyiwe kwi-socket ebhodini le-motherboard.

Enye yemibuzo enzima kunazo zonke engakwazi ukuphendulwa ngokuqondile yile: "Iyini izinga lokushisa elivamile lekhadi levidiyo?". Kungenzeka ukucacisa cishe ukushisa okuvumelekile. Isixazululo esihle kakhulu sokuya kusayithi lomkhiqizi wegraphic processor (hhayi lonke ikhadi levidiyo) futhi ekuchazeni imodeli ethize thola ukubaluleka kokushisa okuvumelekile. Ngesikhathi esifanayo, umuntu kufanele acabange ukuthi ubuchwepheshe obukhona bokukhiqiza kwe- transicor semiconductor abuvumeli ukudala okubili okufanayo, yingakho kuma-batches njalo "ukusabalalisa" okuncane kwemingcele, noma kunjalo, ngaphakathi kwekhasi lesiphambeko. Lokhu kuholela ekwenzeni ukuthi ikhadi elilodwa levidyo likwazi ukuqhubeka lisebenza ngamazinga angu-70, kanti enye, ngokufanayo, kuphela ku-60. Yingakho uma ikhadi levidiyo livutha, abanikazi ngezinye izikhathi babonisa amazinga okushisa ahlukene amavidiyo abo omunye umzila womodeli. Uma kungekho idatha ekushiseni kwiwebhusayithi yomkhiqizi, kungenzeka ukuhlehlisa - ukuthola izilinganiso ezingu-3-4 ezimemezelwe ngabasebenzisi nokunquma ukuthi isilinganiso. Uma ngesikhathi sokusebenza kwesicelo "esinzima" se-3D (umdlalo wekhompyutha) ukushisa akudluli ama-degrees angu-70, ngakho-ke asikho isizathu sokukhathazeka.

Kunezizathu eziningana zokukhula kwezinga lokushisa:

- ukungcola kwe-radiator ekhadini levidiyo ngothuli. Iqiniso lokuthi zonke izingxenye zekhompiyutha zidinga ukuhlanzwa ngothuli izikhathi ezingu-2 ngonyaka, kepha lo mthetho awulandelelwanga kakhulu-ngakho-ke inkinga;

- Misa umshayeli wokupholisa (uma kunjalo);

- ukungahambisani nemibandela ehlinzekwa yi-unit supply unit kuya kumanani adingekayo. Amayunithi angabizi amakhompiyutha aphansi adingeka ukuba ashintshwe njalo eminyakeni engu-1-2, ngoba ngenxa yekhwalithi yabo embi ngemuva kwesikhathi esithile, imingcele iqala "ukuthambisa", iphazamise ukusebenza kwazo zonke izingxenye;

- Ukomisa kokunamathisela okushisayo. Phakathi kobuso be-GPU ne-radiator kunesidingo esiphakathi - ukunamathisela okushisayo. Ngokuhamba kwesikhathi, ilahlekelwa izakhiwo zayo futhi idinga ukushintshwa;

- ukwehluleka kwehadi lekhadi levidiyo ngokwayo. Isizathu esivamile yi-capacitor ye-electrolytic evimba. Futhi, ezinye izinhlobo ze-nVidia (isibonelo, i-9600 GT) zaziwa ngokuthi ngemva kweminyaka eyodwa noma emibili ukuguqulwa kwamagundane e-CPU kubhujiswe, okuholela emiphumeleni engalindelekile - kusukela ekushiseni kwezinga lokufika ekungenakwenzeka kwe-chip;

- Isizathu esiningi kakhulu sokungqubuzana okungalungile kwamapayipi angaphakathi ngaphakathi kweyunithi yesistimu. Uma ukufudumala kuhlala ngaphakathi kwemingcele evumelekile nekhava elihlangothini leyunithi yesistimu isusiwe, ngakho-ke kufanelekile ukucabanga ngabalandeli abengeziwe.
