Izici zekhadi levidiyo NVIDIA GeForce 9800 GTX. Izithombe namabuyekezo

Abathengi abaningi abakhokhisayo bangakholelwa ngokungaqondile ukuthi inkathi yama-video amakhadi esizukulwane esedlule (enezinombolo ezine zamadijithali) sekuphele isikhathi eside. Kodwa-ke, asikho isidingo sokusheshisa ngokukhetha i-adapter entsha entsha yevidiyo kwisigaba sesabelomali, njengoba akufanele sikhohlwe ngenqubomgomo ye-NVIDIA, engavumeli abamele isabelomali ukuthi baphumelele ekuhloleni izizukulwane zesizukulwane esidlule.

Inkulumo kulesi sihloko izohamba kudivayisi ye-top GeForce 9800 GTX. Vumela leli khadi levidiyo limele isizukulwane esedlule, kodwa amandla ayo anele ukuncintisana namaphakheji egeyimu yamanje wevidiyo emkhakheni wesabelomali kanye namadivayisi esigaba sokudlala semidlalo yokuqala.

Ukucaciswa kobuchwepheshe

Igama lekhodi yegraphic core G92 inquma i-speed accelerator engxenyeni ephezulu, futhi uphawu lwe-420 lubonisa ukuguqulwa kwekhadi levidiyo (9800 GTX). Idivayisi idalwe ngokusetshenziswa kobuchwepheshe be-nanometer engama-65 futhi inezigidi ezingu-754 ze-transistors, kanye nazo zonke i-adapters ze-graphics ze-top-end-adapters video. Inani lezinqubo zokusakaza ezivela ku-NVIDIA GeForce 9800 GTX ziyizingcezu ezingu-128, ziyisihluthulelo sokusebenza okuphezulu kwedivayisi.

I-core core isebenza ku-675 MHz kwimodi yokuqokwa. Ukushintshaniswa kolwazi ngebhodi le-motherboard kwenziwa ngebhasi le-256-bit, lenziwe ngokusebenzisa ubuchwepheshe be-DDR3. Imvamisa yebhasi yememori ingu-1100 MHz. Ingxenye ebuthakathaka yekhadi levidiyo yincinjana ye-RAM - kuphela 512 MB.

Ummeleli we-NVIDIA factory

Ikhophi yereferensi yomkhiqizi we-GeForce 9800 GTX ifana ne-flagship ye-NVIDIA GeForce Titan Z umugqa ngobukhulu bayo (ukwahlulela ngesithombe). Ukumangala komsebenzisi ngeke kunqunywe uma kususa uhlelo lokupholisa. Ukubekwa kwamabhethri, amamojula wememori nama-capacitors azoba ngokufanayo. Umehluko kuphela ukuthi i-flagship inezinhlamvu ezimbili zemifanekiso, kanti ummeleli wesizukulwane sokugcina unekristall eyodwa kuphela.

Ngendlela yokubeka izingxenye ebhodini lesifunda eliphrintiwe lekhadi levidyo, ungaphikisana ngokungapheli. Isifiso sabachwepheshe be-NVIDIA ukufaka zonke izakhi ngemuva kwe-adapter yevidiyo akuqondakali kubakhiqizi abaningi bamadivayisi wokugcina. Njengomkhuba wokubonisa, ukufakwa okunjalo kuholela ekushiseni. Uma umsebenzisi efuna ukuba nedivayisi ephezulu yokusebenza, kufanelekile ukubuka imikhiqizo ngokupholisa kahle.

Izinzuzo nezinkinga zedivaysi yokubhekisela

Ukusetshenziswa kwamandla yi-drawback enkulu ye-adapter video ye- NVIDIA GeForce 9800 GTX. Izici zedivayisi zixhomeke ngqo ekunikezeni amandla, okumele kusetshenziswe kwi-speed accelerator yama-watts angu-150. Futhi, abasebenzisi abaningi babonisa ukwehluleka kokusekelwa kwe-DirectX 10. Nakuba ibhasi lememori le-GDDR3 elidlulelwe isikhathi lisebenza kuma-256 bits, lobu buchwepheshe bunemikhawulo ekudluliseni idatha, okungenakwenzeka ukuthuthukisa ngenhla.

Kodwa okufanelekile, okuyiqiniso, kufaka phakathi ikhono lokufaka esikhundleni amamojula wememori. Uma ubheka isithombe sedivaysi, kuyotholakala ukuthi ama-chips ane-soldering ebusweni. Eqinisweni, noma yimuphi umkhiqizi ongenamandla amaningi angakhuphula ivolumu ku-1 GB, nakuba ibhasi lizohlala li-256-bit. Ngokuvamile, akucaci ukuthi kungani ku-laboratories ye-NVIDIA, okokuqala ezobuchwepheshe abazange bafake amamojula amememori akwaziyo.

Izici ze-firmware yedivayisi

Esinye isici okufanele sizinakekelwe yi-BIOS ye-NVIDIA GeForce 9800 GTX. Njengoba iningi labafundi liphawula ekubuyekezweni kwabo, inkumbulo engapheli ye-adapter yevidiyo ayinakho ukulawula okuqinile kwe-hardware ebhodini lesifunda eliphrintiwe. Uma sikhuluma ngolimi olufinyeleleka, i-BIOS yekhadi levidyo ingashintshwa ngokuqonda kwayo, idivayisi izosebenza nemingcele ecacisiwe, noma ingaphakathi kwamakhono ayo.

Eqinisweni, lokhu kuyisici esivamile kubakhiqizi, okuvumela abahleli ukuguqula i-adapter yevidiyo. Emithonjeni, imiyalo eminingi ye-firmware yedivayisi. Isibonelo, uma umsebenzisi enekhasi elilodwa lemifanekiso yokudlala (i-GTS250, 9800GT, i-8800GTX nabalingani bayo), ke emva kokushintsha kwe-BIOS, umsebenzisi we-GeForce 9800 GTX ngaphandle kwezithiyo angasebenzisa kokubili amadivaysi kumodi ye-SLI.

Izidingo zekhompyutha yomuntu siqu

Ungakhohlwa ukuthi kwisizukulwane ngasinye samakhadi wevidiyo kukhona izidingo ezithile zesistimu yekhompyutha yomuntu siqu. Phela, umsebenzi we-adapter yevidiyo, iprosesa kanye ne-RAM kufanele ivumelanise ukuqinisekisa ukusebenza okuphezulu. Njengoba ukuhlolwa kukhonjiswa, ukusebenza kwazo zonke izingxenye eziyisisekelo zesistimu kunconywa ukuthi ibhasi lememori lazo zonke amadivayisi lisekela imvamisa ye-200 MHz (lena intambo eyodwa). Ikhadi lehluzo leGeForce 9800 GTX isebenza ngokuzenzakalelayo kulelijubane.

Iprosesa enezinhlamvu zomzimba ezimbili inganikeza ukusebenza okuhloniphekile. Ngokufanelekile, i-Intel Core Quad Quad eyinhloko engu-4 iyomenza i-adapter yevidiyo isebenze umkhawulo wayo. Ngakho-ke, inkumbulo ye-DDR2 kufanele isebenze kumvamisa wezingaphansi kuka-800 MHz. Ungakhohlwa mayelana ne-hard drive. Ama-drive aqinile e-SSD anesisindo esingabizi kakhulu, kufanele atholakale.

Idivayisi ekhiqiza kakhulu

Ikhadi levidiyo le-NVIDIA GeForce GTX 9800 ngaphansi kwezimpawu ze-BFG ibonakala emakethe njengendlela ekhiqiza kakhulu "imigomo yekhwalithi". Iqiniso liwukuthi umenzi, okwenze izinguquko ezincane kakhulu ohlelweni lokulawulwa kwamandla, ufezekile kahle ngokugqoka ngaphezulu kwegraphic core kanye nebhasi lememori. Ngokuvamile, izenzo ezinjalo zavumela idivayisi ukuthi ibonise imiphumela emihle ezinhlelweni zokuhlola.

Iphikisana kuphela nesistimu yokupholisa, okuyinto ngokubonakala kwayo, ukwahlulela ngesithombe, ayifani ne-reference representative of NVIDIA, ngaphandle kokuthi uphawu lwe-BFG lifakwe phezulu. Kodwa ukukhathazeka ngomnikazi wesikhathi esizayo akufanelekile, ngoba ukuguqulwa kwama-circuits amandla, ukubuyiswa kwesigaba kanye nokwakhiwa kwama-capacitors kuthinte kakhulu ukusetshenziswa kwamandla we-adapter yevidiyo, futhi ngokufanayo, namandla alahlekile.

Ukuthula kuphupha kuphela

I-GeForce 9800 GTX, izici zokusebenza zazibucayi kangangokuthi, ngenxa yokushisa okukhulu kokushisa, abathandi abaningi begeyimu banquma ukuyiyeka. Abekho abakhiqizi abakhona emhlabeni abazange basheshe bajabulise abalandeli babo ngesistimu yokupholisa engabonakali.

Abathengisi abaningi bazosheshisa ukuqinisekisa ukuthi izinkampani ze-ECS kanye neZotac zingayithokozisa amakhasimende ngesistimu ngokuphathwa kwamanzi, kodwa uma kuziwa ekungabikho okuphelele kwezingxenye kudivayisi, lezi zimpawu akufanele zikhunjulwe. Yebo, ngokupholisa amanzi, abakhiqizi bakwazi ukugqithisa i-core MGz kuya ku-800 MHz, bese beka ipharamitha ku-1125 MHz, kodwa inkinga ngomsindo ngeke ixazululwe kubasebenzisi.

Ekuphethweni

Mayelana ne-adapter yevidiyo esekelwe ku-chip ye-GeForce 9800 GTX evela kubakhiqizi abahlukene, ungaxoxa ngokungapheli. Phela, i-flagship yesigaba sokudlala iyinhlayiya enhle kakhulu kuwo wonke amagama adumile. Ngokwemvelo, ngamunye wabakhiqizi baguqule i-PCB, bashintsha amabhethri noma banda inani lememori. Noma yikuphi ukungenelela ngokomzimba kungakwandisa ukukhiqiza komkhiqizo.

Njengoba izivivinyo zibonisa, amakhadi wevidiyo aboniswe ngaphansi kwelogi ehlukene abonisa cishe ukusebenza okufanayo, kodwa ngamanani ahluke kakhulu. Umthengi wokugcina unokuthile okufanele acabange ngakho ngaphambi kokuthenga, ngoba ukukhokhela umkhiqizo sekuyisikhathi eside kungasetshenzisiwe.
