Graphics namafutha, NVidia GeForce GT 440: iimpawu, uthelekiso kunye noontanga kunye nohlaziyo umsebenzisi

isisekelo esihle kakhulu umbutho wemidlalo yemizobo unit entry-level inkqubo - ikhadi ividiyo NVidia GeForce GT 440. Ezi mpawu yalo namafutha ziyafana kakhulu kwi izisombululo uNothozamile yemizobo yangasemva flagship, kodwa omnye ubukho bakhe kwanele ukubaleka ezininzi izicelo yemali ekhoyo.

niche namafutha

In ingxenye lokuqala accelerators yemizobo kwinqanaba ejoliswe nesimilo eziphathekayo. Oku kungqinwe ngalinye iimpawu zawo zobugcisa. ikhadi levidiyo NVidia i GeForce GT 440 unalo kumgangatho wokwenziwa komsebenzi ngamnye ngaphezulu imizobo ehlangeneyo, kodwa ngaphantsi kwe amakhadi yemizobo GTX series. Ngenxa yoko, ubukho ikhadi ividiyo enjalo kwanele ukubaleka ezininzi zokudlala, kodwa hayi kwi izicwangciso aphezulu kangangoko. Iingxaki kungenzeka kuphela xa uzama ukubaleka kwi-PC kunye izicelo zakutshanje gaming namafutha ukuba babe kudinga kwi-hardware, kuquka indlela esezantsi mifanekiso. Kodwa ke kule meko oko kuyimfuneko, kwaye enye ikhompyutha kunye neempawu ezahlukeneyo ngokupheleleyo iinkcukacha.

iimpawu eziphambili videouskoritelya

Inani elipheleleyo umphakathi kwimveliso yomfanekiso zombini 96. Ukuxhaphaka yokusebenza ngokulinganayo umphakathi ngu 810 MHz GeForce NVidia GT 440. Iimpawu ze kumqhubekekisi ukubonisa ukuba basebenzisa rhoqo ka 1620 MHz e. Kwinqanaba iprogram kwi mveliso inkxaso NVidia nobuchwepheshe obuphuma: PureVideo, PhysX kunye CUDA. Kwakhona, ngokutsho ngokwenkcukacha, ixhasa uhlobo lwe Direct X 11,0 kunye Open GL 4.0. namafutha ngokwawo yenzelwe ukuba kufakelwe ulwandiso slot PCI-E 16x 2.0 motherboard. Amaninzi, le iadaptha kufakwa kumazibuko VGA, uqhagamshelwano lwetshiphu emsebenzi kunye DVI. Last phakathi kwezinye izinto yenza kube lula kunye zombini efanelekileyo kwimveliso umfanekiso ngqo kwi esweni 2. Xa uqhagamshele VGA kwizibuko kwemveliso wevidiyo kwifomathi analog, kunye nokulungiswa kwakhe ubuninzi lingamiselwa ukuba 2048x1536. Kwezinye iimeko, sele usebenzisa ikhowudi digital, kunye nokusonjululwa imiselwe ku 2560x1600 eluphahleni.

Chwetheza inkqubo echibini ubushushu. Sezulu pack nobushushu

Umqulu ubushushu GPU na iiwathi ezingama-65. Ukusetyenziswa kwenkqubo sokususa ubushushu isixando eyenza ukuba eli uphawu le GeForce GT ikhadi yemizobo NVidia 440. i Asus, PALIT zonke ezinye abenzi namafutha mifanekiso kuyanyanzeleka ukuba zizalise kumqhubekekisi yemizobo kwakuba nje kufikelelwe injini esebenzayo, equka i radiator aluminiyamu ezibandayo. Ngokutsho zemigaqo, iqondo eliphezulu ukuba evumelekileyo chip yi 98 ⁰ C. Enyanisweni, ngexesha ukusebenza namafutha yemizobo, limited kobubanzi yayo 50-75 ⁰ C. Kwelinye iimfuno nazo makuqatshelwe ukuba inkqubo umbane iyunithi, amandla leyo usebenzisa esezantsi ividiyo ngokusekelwe i namafutha kufuneka ungabi ngaphantsi kwe Watts 300.

RAM, zayo kunokwenzeka uhlobo kunye nebhasi ububanzi

Ukusetyenziswa RAM okanye imigangatho DDR3 GDDR5 ejoliswe NVidia GeForce GT 440. Iimpawu yale namafutha kubonisa ukuba xa zidityaniswe ne yokuqala udidi RAM frequency yayo yokusebenza 0,9GGts ngokulinganayo, kodwa kwimeko yesibini, eli xabiso liza kwanda yaye iya kulingana 1, GHz 6. Bandwidth for DDR3 wamemezela 28 Gb / s, nangenxa GDDR5 - 51 GB / umzuzwana. Bit memory ibhasi njengoko onke accelerators kolu ngcelele iyafana kwaye ilingana 128 ziintanda. Nangona ukusetyenziswa GDDR5-RAM standard, ngakumbi kukhethwa, ngokwemigaqo yokusebenza, kodwa inzuzo enkulu ukusuka ukusetyenziswa kwaso asifunyenwanga kule meko. Esona sizathu ilele apha umthamo wayo, nto leyo kule ngobuwena ezingama-512 MB, yaye oku ngokucacileyo azonelanga ukuba umsebenzi ekhululekile kunye screens ophezulu isisombululo. Kodwa xa izixhobo ividiyo enjalo DDR3 memory ivideo uxhaso umthamo angandiswa ukuya ku-1 GB okanye 2 GB. Oku sele esaneleyo ixesha lenene imifanekiso engafumanekiyo eziphakamileyo, kodwa ukusetyenziswa kwe lixesha ngalo RAM mzuzu kuchaphazela kwintsebenzo zombini asiyondlela ilungileyo. zokugqibela ezingqale esezantsi memory yemodeli yemizobo zinikwe kule theyibhile.

Analogs kunye nokuthelekisa nabo

imizobo Integrated na okhuphisana eziphambili NVidia GeForce GT 440. Uphawu, ebonelela kwinqanaba eliphezulu iiPC yokusebenza ne imizobo ekhethekileyo - Yindlela ividiyo buffer eyahlukileyo ngokwandayo ukubhobhoza. Kungenxa lo msebenzi ukuze kuphuculwe intsebenzo kule meko. Xa kusetyenziswa usebenzisa esihlangeneyo isakhelo ividiyo buffer njengenxalenye memory inkqubo, ufikelelo apho iadaptha ifumana ngokunxuseneyo kunye CPU. Kwakhona kulo mzekelo, ubude elithi RAM elincitshisiweyo kunye rhoqo yayo nokuncipha bandwidth. Konke oku yakhiwe ngokupheleleyo ngokuphathelele accelerators CPU for Radeon kunye neetships AMD HD Graphics for "Intel" esixhasiweyo. Ngoko ke, ukuba andise ngcono yonke intsebenzo yeli PC yakho ukufaka imali encinci kwaye ufake obubobu yemizobo namafutha kwinqanaba lokuqala. Kulo mzekelo inzuzo ngokwemigaqo yokusebenza ibonakala.

Price namafutha. ukubuyekeza umsebenzisi

Kule imeko entsha yale ikhadi levidiyo ukuyithenga akusekho kunokwenzeka. elide Kuye kwaba ngaphandle kwemveliso, kunye noninzi wathengisa ngayo. Xa imeko wasebenzisa, le namafutha zingathengwa ngexabiso ngaphezulu akukho kwama-4,000 engange. Iindleko ezinjalo elihambelana ngokupheleleyo parameters kunye nokusebenza NVidia GeForce GT 440. Le uphawu eli khadi yevidiyo inxalenye yabanini ibonisa ukuba oku isisombululo enkulu lokumisela yevidiyo esezantsi umdlalo entry-level-PC. ukushiyeka ebalulekileyo asikwenzi.

iziphumo

Nali ikhadi enkulu yemizobo entry-level kuyinto Iimpawu NVidia GeForce GT 440. kunye nexabiso namafutha yemizobo inqanaba yayo ukuthobela ngokupheleleyo ekuqaleni. Kulo mzekelo, ukuqukwa yemizobo obubobu ezifana kakhulu kwandisa isantya kwenkqubo yekhompyutha kwaye ikuvumela ukuba ngokukhawuleza ukusombulula imisebenzi resource-olunzulu.
