Graphics ikhadi Geforce GTS 450: iinkcukacha, izimvo

Bonke abasebenzisi Kudala kusetyenziswa ingcamango yokuba iinketho iindleko ophantsi amakhadi evela nVidia - it ukwaliwa kwicandelo imali eninzi emalunga neklasi uqobo. Noko ke, ukufa elolo hlobo akuthethi kuchaphazela onke amakhadi imizobo, kukho izixhobo eziyilelwe ngabom ukwenzela crespo zexabiso eliphantsi. Umzekelo, i-Geforce GTS 450, iimpawu indawo yayo yokuba ukuba ngokupheleleyo isixhobo ezimeleyo.

indawo kulindeleke

Xa sifundisisa nasekusungulweni umenzi ikhadi levidiyo ukubona nVidia, oko kunokubonwa ukuba iminyaka emininzi Geforce GTS 250 wahlala ngaphandle ezihlangwini. Emva 260 series liye lathatyathelw 'indawo 460 imodeli enamandla ngakumbi, kuba uthelekiso. Ngokwendalo, imarike kulindeleke ukubonakala Geforce GTS 450, kufuneka zihambelane iimpawu uhlelo wayo, kodwa abe ukusebenza ngcono.

Nazi ungumlimi nje wangena ezingalunganga kubathengi xa umdlalo uqalise kunye rebranding ikhadi levidiyo Geforce 8800 no 9800, ukutshintsha inkqubo yabo yokuvelisa ngokuguqula rhoqo yokusebenza nokwenza zokuphawula efanelekileyo (GT, GTS, GTX, GTX +). Enyanisweni, iminyaka eliqela umenzi ubeke phezu kwimarike iinguqulelo ezininzi ikhadi efanayo. Abasebenzisi abaninzi, ngubani ukuqonda iimpawu ikhadi levidiyo, kwakungekho bamangaliswa ngaphantsi emva kokungena imarike Geforce GTS 450, nto leyo enyanisweni kuphela oluphuculiweyo inguqulelo ye Geforce 8800 GT, kodwa yikristale yayo.

iimpawu technical

Graphics iprosesa GF106, endingowakhe nVidia Fermi ngezakhiwo iyilelwe ngqo kumgca entsha imveliso ka izixhobo zexabiso eliphantsi GTS Geforce 450. iinkcukacha yobugcisa kule divayisi ezahlukeneyo phantse isiqingatha iimodeli abadala Geforce GTX 460:

• GPU 192 ixhasa iprosesa jikelele 24, kunye ROP 32 unit texture;
• mveliso setting olungundoqo into clocked kwi 783 MHz;
• ukusebenza imemori ekhoyo ezintathu isilawuli -bit 64, kodwa ke omnye wabo ukuba angenzakali, ngoko ke ivili le ubunzulu yevidiyo isuntswana 128 ziintanda.

Kuyabonakala ukuba, yemifanekiso umdlalo Geforce 8800 yi nempembelelo entle kakhulu ngengeniso umenzi, ekubeni imodeli Geforce GTS 450 wabonakala iinguqulelo ezininzi kakhulu. Bona kwagcwala emarikeni asabamba zonke yayigcinwa ixabiso kwi store ezishelifini de izixhobo ephezulu.

kokulungiswa

Okokuqala sithetha uhlobo khadi eye Geforce GTS 450. Amanqaku GDDR3 kunye GDDR5 zahluke rate data eseyiphantse kabini ephakamileyo uhlobo ngakumbi ithekhinoloji ephucukileyo. Kodwa ixabiso isixhobo oluneentlobo ezahlukeneyo memory yohlukile kancinci. Kwaye ukuba ukukhumbula ukuba umenzi sele ngabom sinamafu umsebenzi omnye umlawuli bit-64, ngoko yonke into kucaca kuba kwenziwa yintoni injongo. Ngoko ke market kwabonakala yala maxesha Geforce GTS 450 iadaptha, ububanzi ibhasi ka 192 amasuntswana kunye nomthamo 1536 MB ebhodini.

Kwaye ukuba wenze uvavanyo, uze uthelekise zonke ulungiso phakathi kwabo kunye okhuphisana ekufutshane uhla amanani, kunokwenzeka ukuba uphi lo mkhuba. Ikhadi aphezulu yemizobo yaseqongeni ukusuka lonke Geforce GTS 450 uhlelo wokusebenza efanayo njenge uguqulelo azabi-phantsi yemodeli top GTX 460 768 MB.

segolide ukuthini

Umlinganiselo woviwo "ixabiso-ixabiso" inkokeli imarike Russian yaba Asus Geforce GTS 450. Izikhankanyi Product Akunakuba nengqondo nabadlala ngenene enomtsalane, kodwa ke ixabiso uyakwazi kutsala umdla kubathengi abaninzi. Apha, umenzi eTaiwan ividiyo-eyaziwa linyuke kancinane kuphela rhoqo undoqo GPU, kunye nazo zonke ezinye iimpawu musa sahlukile abalifunayo parameters nVidia umenzi. Nditsho inkqubo sokupholisa, ezo mveliso ikhangeleka disappointingly, ayizange ngcono.

Njengokuba ke oko kwazeka, lo Asus umenzi likhuphe esinye isixhobo isekelwe Geforce GTS 450 kwabanye amazwe. iadaptha Video kubekwe isixhobo umsebenzi ofisi. Ezona mpawu ziphambili zezi GDDR3 ividiyo memory, njalo iprosesa graphic iyintsimbi- kwisixando sokwenziwa. Fumana le ikhadi levidiyo umdla wokwenene kakhulu ukuba kwiivenkile angaphandle kwi-intanethi.

Ukuze imivundla ezimbini

imigangatho kabini, ukubambelela intengiso yenkampani kunye Palit. ngumqondo yabo imelwe kwiinguqulelo ezininzi ezijolise yayigcinwa ngexabiso ezahlukeneyo. isixhobo olubizayo yakhiwe ngokusekelwe GDDR5 kwaye kwandise isantya undoqo inkumbulo, kwaye umzekelo mali isebenzisa GDDR3 neetshiphusi. Kodwa izixhobo cheap ziyafumaneka kunye ezahlukeneyo umthamo yevidiyo memory ebhodini - iinketho-1 GB no-2 GB. Noko ke, iingcali ezininzi zithi ukwanda yokusebenza yokudlala Ubungakanani benkumbulo aluchaphazeli, yaye ibizwa ngokuba ukuguqulwa oluphuculweyo icebo sentengiso.

Zonke ezinye iimpawu Palit Geforce GTS 450 efanayo. Nokuba uhlelo apho ngokusengqiqweni kufuneka ibe namandla ngakumbi ukuba kukho izixhobo ezixabisa akukho uphawu ubhedu okanye aluminium zokutyubhisha okupholisa. Akuqhelekanga kakhulu, ngenxa yokuba umenzi liye landa nge-10% rhoqo olutyunjwe core yemizobo.

umdlalo, umzekelo

Kodwa inkampani Gigabyte iye yaziswa kwi kwimarike umbono yaso nendlela kufuneka ikhangeleke njenge ikhadi levidiyo graphic Geforce GTS 450 1GB. Iimpawu ifowuni abe overclock mveliso encinane undoqo, enika abanye okhuphisana iingenelo yevidiyo. Noko ke, lo msebenzi osemqoka eziphambili ixhomekeke injini obuphuma ebizwa WindForce 2X, eye radiator yalo netyhubhu ezimbini ukusasaza ubushushu. Ngokuqhelekileyo, kukho iifeni ezimbini ezinamandla, isantya yabo olawula eli ivideo adaptha eyakhelwe-ngaphakathi.

Xa nokubuyekezwa ezininzi abanini eendaba, professional injini ikhadi levidiyo efanele lula unikezelo kwaye olusuka nobushushu banal. Ngenxa yoko, empirically, enkosi iimvavanyo zokwenziwa kunye software overclocking eluncedo kunye nVidia Inspektor, ukwandisa imveliso nge 15 per cent yarekhodwa.

Ukuba uyakholwa nokubuyekezwa

Zokuzilinganisela ezithambileyo kunye nohlaziyo isixhobo eendaba ukuvumela ukuba bafunde iimpawu ungabona uluhlu okhuphisana ekufutshane kwitheyibhile yokusebenza. Kodwa oku akwanelanga ukuba abathengi abaninzi ezinokwenzeka, ngenxa yokuba uninzi review axhase, ngenxa yokuba iinkampani ukukhuthaza iimveliso zabo. Ngoko ke, akukho ukubuyekeza ze abanini andikwazi ukwenza apha.

Le eziluncedo ziquka ikhadi iindleko ividiyo eliphantsi ezivenkileni, ngokuba iklasi izixhobo wemidlalo. inkqubo Simple Ukupholisa kuzichaphazela kakhulu isixa yevidiyo - kule version uyifake nkqu kwimeko Tower midi. Ngo-mveliso sibeka inkqubo okupholisa nokubaleka cwaka kakhulu, nkqu umthwalo incopho, oko kukholekileyo kakhulu bonke abalandeli imidlalo ebusuku.

Le ethile le yokusebenza. Zidityaniswe yamluma memory ibhasi 128 kwi Geforce GTS 450 iinkalo eziya kuba phantsi kakhulu xa kuthelekiswa kukhuphiswano kule ngexabiso, kodwa ibhasi 192 okanye 256 ziintanda. Kuba ikhadi ividiyo usebenzisa imemori ngevidiyo GDDR3 uhlobo, ongaqondakaliyo ngokupheleleyo ukuxhasa iDirectX 11 Nvidia Physx, akukho apho intsebenzo kunokuba akukho mbuzo.

Ekuphetheni

Xa nokubuyekezwa amaninzi, oku akwenzi ngqiqo ukufumana isiphoso ikhadi yemizobo ezisekelwe Geforce GTS 450. Izikhankanyi Product ekuqaleni ezikhoyo ukuze zisetyenziswe eklasini mali, ngokulandelelana, kwaye ixabiso le liphantsi kakhulu. Onqwenela ukuba isixhobo iadaptha enamandla ngakumbi 460 ukuze uthenge la manqaku, nto leyo amaxesha enye enesiqingatha ibiza ngaphezu abaqeshwa bakarhulumente. Kodwa ukuba injongo umthengi lowo kwingongoma nganye "ixabiso-ixabiso", imodeli 450 yi wegolide nje omnye kusho oyifunayo. Ukongeza, njengoko ibhonasi, umthengi uya kufumana isixhobo cwaka encinane kakhulu engayi esingenakubangela naliphi na inkxamleko kumnini umsebenzi, kwaye inkqubo obandayo.
