Ihluzo ikhadi Geforce GTS 450: Ukucaciswa, ukubuyekezwa

Sekuyisikhathi eside Bonke abasebenzisi ukujwayela ukuthi ongakhetha izindleko eliphansi isiqophi amakhadi kusuka NVIDIA - ke ukwenqaba ingxenye ezibizayo eziphathelene isigaba sephizela. Nokho, uthola isiphetho esinjena akuphazamisi wonke amakhadi ihluzo, kukhona amadivayisi zenzelwe ngamabomu ngoba eziphansi niche. Ngokwesibonelo, Geforce GTS 450, izimfanelo waso yokuthi kuba ngokuphelele kudivayisi ezimele.

esikhundleni kulindeleke

Uma sitadisha ukuvela nomkhiqizi isiqophi ikhadi ukubona NVIDIA, kungabonwa ukuthi kwaphela iminyaka Geforce GTS 250 wasala engasenabo esikhundleni. Ngemva 260 chungechunge itsetfwe elinamandla kakhulu 460 imodeli, ukuqhathanisa. Ngokwemvelo, emakethe kulindeleke ukubukeka Geforce GTS 450, kumelwe kuvumelane nezici uhlelo yayo, kodwa abe ukusebenza okungcono.

Nazi nje umkhiqizi langena ezingenabulungisa ukuba abathengi lapho umdlalo kwaqala rebranding isiqophi ikhadi Geforce 8800 futhi 9800, ukushintsha inqubo yabo yokukhiqiza ngokushintsha imvamisa yokusebenza nokwenza kophawu ezifanele (GT, GTS, GTX, GTX +). Empeleni, kwaphela iminyaka eminingana nomkhiqizi esebeké emakethe ukuhlukahluka eziningana ikhadi efanayo. Abasebenzisi abaningi, abaziqondayo izici ikhadi isiqophi abengasesiyo kancane bamangale ngemva kokufaka emakethe Geforce GTS 450, okuyinto empeleni kwaba kuphela inguqulo ethuthukisiwe ye Geforce 8800 GT, kodwa nge crystal lalo.

izici lobuchwepheshe

Ihluzo processor GF106, okuqondene NVIDIA Fermi izakhiwo iye elakhelwe entsha umkhiqizo line amadivayisi eziphansi Geforce GTS 450. Ukucaciswa kobuchwepheshe zale divayisi zihlukile acishe abe yisigamu onobuhle amadala Geforce GTX 460:

• GPU 192 isekela processor jikelele 24, futhi ROP 32 ukuthungwa iyunithi;
• core ifektri kulungiselelwa clocked at 783 MHz;
• ukusebenza imemori ekhona ezintathu isilawuli -bit 64, kodwa esinye sazo bekhubazekile, ngakho sakhathala ividiyo kancane 128 izingcezu ukujula.

Ngokusobala, umdlalo onobuhle Geforce 8800 kuyinto nomthelela omuhle kakhulu ku nomholo umenzi, kusukela imodeli Geforce GTS 450 wabonakala ukulungiswa amaningi kakhulu. Bona Ugcwalise emakethe futhi uthathe zonke niches intengo esitolo emashalofini kuze kumadivayisi phezulu.

ukulungiswa

Okokuqala sikhuluma uhlobo imemori khadi ukuthi ine Geforce GTS 450. Izici GDDR3 futhi GDDR5 kuhluke idatha izinga okuyinto cishe kabili ephakeme ohlotsheni ngaphezulu ubuchwepheshe eyinkimbinkimbi. Kodwa intengo idivayisi izinhlobo ezahlukene inkumbulo ehlukile kancane. Futhi uma khumbula ukuthi umenzi ivimbe umsebenzi olulodwa-64-bit isilawuli ngamabomu ke konke kuba sobala ngayiphi injongo ke kwenziwa. Ngakho emakethe kwaqhamuka olwesimanje Geforce GTS 450 adaptha, ububanzi lebhasi 192 izingcezu kanye umthamo we-1536 MB ebhodini.

Futhi uma senza ukuhlolwa, futhi uqhathanise zonke ukulungiswa phakathi kwabo kanye izimbangi eseduze range intengo, kungenzeka ukulandelela mkhuba. The esiphezulu abacula ihluzo ikhadi kusuka lonke Geforce GTS 450 uhlelo ine ukusebenza efanayo inguqulo zihlubule phansi imodeli phezulu GTX 460 768 MB.

segolide kusho

Isilinganiso "intengo-izinga" umholi wemakethe isiRashiya kwakuwulimi Asus Geforce GTS 450. Umkhiqizo Imininingwane neze kubonakale abadlali ezikhangayo wangempela, kodwa intengo uyakwazi zidonse ukunaka kwanoma abathengi abaningi. Lapha, umenzi Taiwanese isiqophi elaziwayo kancane kuphela anda imvamisa core GPU, kanye nazo zonke ezinye izici musa ihluke okushiwo imingcele NVIDIA umakhi. Ngisho uhlelo Ukuphola, okuyizinto ifektri ubukeka disappointingly, awuzange ngcono.

Njengoba yabe seyaziwa, le ASUS nomkhiqizi ukhiphe enye idivayisi esekelwe Geforce GTS 450 kwabanye amazwe. Isiqophi adaptha isebangeni njengoba idivayisi umsebenzi ehhovisi. Izici eziyinhloko inkumbulo GDDR3 ividiyo, imvamisa ongaphakeme processor ingcaca kanye nokupholisa yekwentiwa. Thola le vidiyo ikhadi ezithakazelisayo ngempela wangempela angaphandle ezitolo online.

Ukuze onogwaja ababili

ombaxambili, banamathele ukumaketha yenkampani kanye Palit. brainchild yabo umelwe ezinguqulweni eziningi okuhloswe ngazo ezahlukene intengo niches. kudivayisi Expensive yakhiwe ngesisekelo GDDR5 ngaphambili futhi iye yandisa speed core kanye inkumbulo, futhi Ngokwesibonelo isabelomali isebenzisa GDDR3 chips. Kodwa amadivayisi ezishibhile ayatholakala nge ezahlukene umthamo inkumbulo isiqophi ebhodini - okukhethwa kukhona 1 GB futhi 2GB. Nokho, ochwepheshe abaningi bathi amageyimu ukusebenza ukwanda inani lememori akuphazamisi, futhi ubizwa ngokuthi ukuguqulwa ngcono icebo lokumaketha.

Zonke lonke Geforce GTS 450 Palit izici ayafana yini. Ngisho ukupholisa isistimu ukuthi amaphi ngokunengqondo kumele kube namandla kakhulu i-apharathasi ezibizayo akuyona ithusi noma aluminium tubing uphawu. Kuyinto eyisimanga impela, unikezwa iqiniso ukuthi umenzi liye lenyuka ngo-10% imvamisa okuzisholo ihluzo core.

umdlalo Ngokwesibonelo

Kodwa inkampani Gigabyte usanda kwethula lento emakethe umbono ayo kufanele sibheke indlela like isithombe isiqophi ikhadi Geforce GTS 450 1GB. Izimpawu idivayisi abe imboni overclock encane umnyombo, esinikela ezinye izimbangi izinzuzo vidiyo. Nokho, isici esiyinhloko sitholakala nokuphathelene Ukupholisa uhlelo okuthiwa WindForce 2X, esesikhundleni kurediyetha ayo nge amashubhu ezimbili ukushabalalisa ukushisa. Ngokwemvelo, zikhona abalandeli ezimbili ezinamandla, isivinini sabo elawula esakhelwe adaptha yevidiyo isilawuli.

Ukwahlulela ngokubukeka izibuyekezo eziningi wabanikazi abezindaba, nge professional Ukupholisa uhlelo isiqophi ikhadi kalula amenable ukuba ukusheshisa futhi hhayi inqanyuliwe okweqile banal. Ngakho, empirically, sibonga ukuhlola zokwenziwa isofthiwe Overclocking Umbuso nge NVIDIA inspektor, ukwandisa umkhiqizo ngo-15 per cent sabhalwa.

Uma ukholelwa ukuthi Izibuyekezo

Zokubekisa Zokwenziwa nedivayisi Izibuyekezo kwabezindaba asivumela ukutadisha izici ubone uhlu esincintisana eliseduze ethebuleni ukusebenza. Kodwa lokhu namanje akwanele amakhasimende amaningi ezingaba, ngoba iningi izibuyekezo umxhasi, ngenxa izinkampani ukuthuthukisa imikhiqizo yabo. Ngakho-ke, akukho izibuyekezo abanikazi bawo abakwazi ukukwenza lapha.

Izinzuzo zihlanganisa ongaphakeme izindleko isiqophi ikhadi emakethe, ngokuba isigaba amadivayisi okudlala. Simple Ukupholisa uhlelo kuthinte kakhulu inani ividiyo - kule nguqulo ungafaka ngisho ku Okuningi umbhoshongo icala. Ngo ifektri ukubeka uhlelo ukupholisa kuyinto ukugijima ethule kakhulu, ngisho umthwalo isiqongo, okuyinto kumjabulisa kakhulu bonke abalandeli imidlalo ebusuku.

I ethile kuyinto ukusebenza. Engavamile alunywe inkumbulo ibhasi 128 ngesikhathi Geforce GTS 450 izici kuyoba eliphansi kakhulu uma kuqhathaniswa mncintiswano ngalesi intengo, kodwa ibhasi 192 noma 256 izingcezu. Ukuze ikhadi ividiyo usebenzisa imemori isiqophi ka GDDR3 uhlobo, engaqondakali ngokuphelele ukusekela IDirectX 11 futhi Nvidia Physx, futhi zazo ukusebenza kungaba kungabaza.

Ekuphetheni

Ukwahlulela ngokubukeka izibuyekezo eziningi, ke akwenzi mqondo ngenjongo yokuthola amaphutha kanye ihluzo ikhadi esekelwe Geforce GTS 450. Umkhiqizo Imininingwane ekuqaleni zitholakalele ukusetshenziswa isigaba isabelomali, ngokulandelana, futhi intengo ngoba lokhu liphansi kakhulu. Ubani ethanda ukuba adaptha yidivayisi enamandla ngaphezulu 460 lingase lithenge lowo chungechunge, okuyinto izikhathi eyodwa nengxenye eqolo ngaphezu kwanoma abasebenzi isimo. Kodwa uma injongo ikhasimende iyona umbandela we "intengo-izinga", imodeli 450 kuyinto efiselekayo segolide kusho eyodwa nje. Ngaphezu kwalokho, njengoba ibhonasi, umthengi uzothola kudivayisi onokuthula ezincane kakhulu ukuthi ngeke kubangele yikuphi okungalungile umnikazi umsebenzi, futhi inqubo obandayo.
