NVIDIA GeForce GTS 450: izici. ikhadi Isiqophi NVIDIA GeForce GTS 450: umshayeli

Uma sicabangela imizamo yokuqala NVIDIA Corporation kudalwa isiqophi amakhadi ukusekela IDirectX 11, kubalulekile ukuphawula ukuthi abaphumelelanga kakhulu. Nokho, ukuze ingene esikhundleni isipiliyoni abokuqala isizukulwane esilandelayo imikhiqizo, okuyinto, ngokusho umkhiqizi, hhayi kuphela eseyiqedile amaphutha odlule, kodwa futhi ngcono ukusebenza. Ingabe kuyiqiniso lokhu? Zama ukuqonda, kokucubungula NVIDIA GeForce ihluzo ikhadi GTS 450, izimfanelo okuyinto enze kube nokwenzeka ukuba bakubize a middling eqinile.

ifektri Overclocking

Ikhadi isiqophi ibekwe njengoba overclocked ngaphambi kokuthenga. Ucwaningo eningiliziwe OC wukuthi imvamisa core ulele, njengoba kuqhathaniswa ezinezici ejwayelekile, ukuba 27 MHz, kodwa inkumbulo lithole inzuzo ngisho kancane - 8 MHz.

Akubuzwa ukuthi inzuzo ukusebenza kusukela manipulations okunjalo kuyoba ngokuphelele engenamsebenzi? Nokho, a gimmick ukumaketha enjalo ikuvumela ukuba uhlanganyele phezu GeForce GTS 450 le-NVIDIA intengo ephakeme ithegi. I nezinye izici efana ncamashí isampula ejwayelekile.

Iphakheji Lokuphakathi

Ikhadi isiqophi is zahlanganiswa ebhokisini encane ezimibalabala. Ngakwesokudla yazisa kuphela umsebenzisi igama imodeli, usayizi inkumbulo, futhi nokuphathelene NVIDIA ubuchwepheshe eziningana. Lapha kungenzeka ukuthola izwi ikhadi NVIDIA GeForce GTS 450 unikezwa uhlelo Ukupholisa ethuthukisiwe, umnyombo okuyinto wazenza ngethusi.

iphakethe engemuva futhi akasibaleli iziphambeko umsebenzisi ezinemininingwane incazelo NVIDIA GeForce GTS 450: Ukucaciswa ethulwa lapha kuphela eyisisekelo kunazo. Cishe yonke indawo ilawulwa imibhalo ukukhangisa ku ubuchwepheshe nokuphathelene. Advance ukusho ukuthi amandla uhlelo Iyunithi enikeza kumele abe okukhiphayo Imininingwane Watts 400, futhi emgqeni 12V ukunikeza 22 Ampere.

Ngaphezu isibonisi adaptha iphakethe, ungathola:

• Laser disc namanye amathuluzi awusizo for the NVIDIA GeForce GTS 450, umshayeli ukhona idrayivu.
• Adapters DVI-VGA, miniHDMI-HDMI, kanye wire elikuvumela ukuxhuma amandla ezine-pin isiqophi ikhadi amandla okuphathelene nomngcele.

Asinakusho ukuthi enikeziwe abacebile, kodwa ngendlela efanayo lebanga lentengo ubhekwa indinganiso isethi. umsebenzisi Simple yakho konke lokhu kuyoba okwanele umsebenzi ukhululekile. I yokuntula kukhona ukuntuleka SLI-ibhuloho, kodwa ke, kufanele kuqashelwe ukuthi lesi sici cishe njalo ingxenye iqoqo ephelele umbadlana, uma ine- ezimbili PCI EZISHIWO isixhumi.

ikhadi Isiqophi NVIDIA GeForce GTS 450 unikezwa isibalo interface ejwayelekile amadivayisi yokuxhuma (ezimbili DVI-mina omunye mini-yocezuningi). Okungukuthi, ihluzo processor kungenziwa exhunywe ngabaqaphi abathathu ngesikhathi esifanayo ngaphandle kwenkinga.

nezinto zikagesi

Isifunda ephrintiwe ibhodi ihluzo ikhadi akuhlukile iningi NVIDIA adapters eyakhelwe chip efanayo. Ohlangothini emuva kulo bangabantu inkumbulo chips amane, okuyinto siphuce kubo kwanoma iyiphi indlu. Kungani onjiniyela wakhetha isakhiwo esifanayo kuseyimpicabadala, ngoba ohlangothini front ikuvumela ukusetha IMS ncamashi khona. Futhi ngemuva isilawuli yezintambo. Kodwa njengoba sekushiwo ngaphambili, amandla olunikezwa isondo PSI EZISHIWO, eyanele NVIDIA GeForce GTS 450 (isiqophi Ukucaciswa zidinga ukuthi ukuxhuma eziyisithupha-pin amandla isixhumi).

I Ingcenye ephakathi yesigaba iyiphi idivayisi ezifana - ihluzo core. Igama layo - GF 106, kanye nenqubo ubuchwepheshe - 40 NM. Kuhlanganisa processor 192 shader, rasterization amabhlogo lapha 16. idatha exchange nge inkumbulo isebenzisa ibhasi 128-bit.

Inani lememori ividiyo - 1 GB, okuyinto ibangelwa iqoqo izifunda okuhlangene eziyisishiyagalombili. Ukumaka chips uthi behileleka ukuthuthukiswa inkampani SAMSUNG. ukufinyelela isikhathi inkumbulo - isigamu nanosecond. Uma sibona, ngemcondvo, lokhu kuyokwenza ukuba ukuhlakazeka kuze kufinyelele ayizinkulungwane 4 megahertz. Ekuqaleni, umenzi walesi ipharamitha isethwe ezingeni 3600.

Ukupholisa uhlelo

Ngaphezu kwalokho akuphazamisi ukusebenza ifektri Overclocking ikhadi vidiyo ukuhluka eningini amadivayisi efanayo kwakheka kwi-GPU efanayo, esebenzisa uhlelo ngokwezifiso indlu. Siqukethe izindlu plastic, fan ngenhloso ububanzi 8 cm kanye aluminium ukushisa echibini letinalokubalulekile zethusi. Izakhi metallic nabo kuphela processor, kuyilapho chips inkumbulo futhi ukudla akuyona selehlile okwengeziwe nganoma iyiphi indlela.

Kufanele kuqashelwe ukuthi ikhadi isiqophi yakhelwe ukuze imvamisa incipha umthwalo kuyehla ngokuzenzakalelayo futhi lokhu kusenza ukunciphisa amandla ukusetshenziswa nokushisa. Uhlelo lusebenza ezingeni BIOS, asethwe NVIDIA GeForce GTS 450. Umshayeli akuphazamisi isimo.

Ukuze ukuhlola ukusebenza kwale ndlela, ikhadi isiqophi lwavivinywa ithuluzi FurMark. Ukulungiswa Automatic isivinini fan at umthwalo eliphezulu elivunyelwe ukuxoxa nucleus akukho kuka-degree angu-60. Into ezithakazelisayo wukuthi fan baphotha ngalesi sikhathi akuyona ezingaphezu kuka-17%. Ngenxa yalokho, kunomsindo ukuthi lincane. Ngemva isivinini kulungiselelwa bhukwana 100% lokushisa zehlele, ngo-degree 2-4 kuphela, ezikhathini olindele kunazo, Nokho isikulufa operation uhlala ethule efanayo.

Kuphela esiphethweni esisodwa: i ukupholisa uhlelo design ilula, kodwa owenza umsebenzi walo kahle, babonisa umsindo ezingeni eliphansi.

Gaming Ukusebenza

NVIDIA GeForce GTS 450, okuyinto nobuntu umcabango, ahlanganisa ikhadi vidiyo ukusebenza eqinile Ngokwesilinganiso, ubonisa ezingeni eliphansi ukusebenza komfundi. Factory overclock futhi musa kuthinte inani zopholi zokubekisa futhi ezingeni FPS imidlalo.

kudivayisi Ukucaciswa kuyoba okwanele ukuba ugijime yimuphi umdlalo wanamuhla, kodwa inqwaba izilungiselelo ihluzo kufanele ushintshele ongaphakeme noma ophansi.

ukusheshisa

Overclocking ihluzo ikhadi kungasetshenziswa MSI Afterburner Umbuso indawo. Ngalo, processing speed zingandiswa ukuze 950 MHz, isb 15%, futhi imvamisa inkumbulo - ukuze 4690 MHz (30% ukwanda). Into umxhwele kakhulu ukuthi adaptha emva zonke izinguquko uqinile, nakuba chips kungukuthi selehlile.

Yiqiniso, noma ikuphi ukwanda imvamisa kuzoholela ukushisa anda futhi zidinga amandla amaningi, kodwa kokusebenza kuzoshintsha izilungiselelo ihluzo ukuze ongaphakeme ukuze alungise, futhi ngezinye izikhathi kuze okusezingeni eliphezulu.

isiphetho

ikhadi Isiqophi NVIDIA GeForce GTS 450, ezibekiweko lobuchwepheshe esingenakubalwa ngokuthi eqinile - kungcono esincintisana enkulu izinkampani umkhiqizo AMD sika, ukuze ezifana HD 5750 futhi 5770. Kuyinto kangcono abasebenzisi abangabhalisile kakhulu bafune ngokuya imvamisa.

Intengo a ihluzo namafutha kancane kakhulu, kodwa ngenxa Overclocking amathuba amaningi, futhi ethule uhlelo Ukuphola, le nkinga akakwazi ngokuthi ezibucayi.

NVIDIA GeForce GTS 450. inkumbulo Palit GDDR3 futhi

Palit ukhiphe ikhadi isiqophi asigcini nje ngokulalela okushiwoyo chips inkumbulo GDDR5, kodwa GDDR3. Intengo-product efanayo nalena usunciphe ngamaphesenti yesithathu. Umqondo ukusungula adaptha ezinhle kancane GDDR3-chip nje kuphela ongaziwa, kodwa futhi impikiswano. Ngemva kokufunda ku ibhokisi igama elidala, umsebenzisi ukuthenga umkhiqizo, ukusebenza okuyinto uvezwa ezingeni ehluke ngokuphelele.

Kusukela imodeli egcwele ku-3D-izicelo like umkhiqizo kwasalela emuva ngo 30-60%. Futhi ukuze sivale lapho sisilela lokhu igebe uye ngisho wathola Overclocking esiphezulu. Umthamo ezibuthakathaka chips inkumbulo ayivumeli ukufinyelela okufanayo FPS amagugu, ngisho noma ikhenela overclock ku-30%. Ukusebenza umehluko phakathi ngokugcwele kanye onobuhle zihlubule phansi kuyinto 15% cishe zonke izivivinyo.

umkhiqizo okunjalo kufanelekile abasebenzisi ngeke ukusebenzisa izicelo isisetshenziswa okhandlayo, kodwa ngenye indlela yokuxhasa umnotho kuzoholela isidingo sokwenza izilungiselelo iningi imidlalo ku-amazinga aphansi.
