NVIDIA GeForce GTS 450: āhuatanga. kāri Video NVIDIA GeForce GTS 450: taraiwa

Ki te whakaaro tatou nga ngana tuatahi o NVIDIA Corporation i te hanga o te kāri ataata e tautoko DirectX 11, he mea e tika ana ki te mōhio e kore i ratou angitu rawa. Heoi, ki te whakakapi i te wheako tuatahi ka haere mai te whakatupuranga i muri o ngā hua, i, kia rite ki te kaiwhakanao, whakakorea kore anake nga tōnounoú o mua, engari pai ake ano hoki mahi. He pono tenei? Whakamātauria ki matau, ka whakaaro te NVIDIA GeForce kāri whakairoiro GTS 450, nga āhuatanga o e hanga i taua mea taea ki te karanga i reira i te middling kaha.

overclocking wheketere

te tūnga o te kāri ataata kei te rite te overclocked i mua i te hoko. He ako taipitopito o OC ko e rimurapa te auau matua, pera whakaritea ki āhuatanga paerewa, ki 27 MHz, engari kua riro te mahara noa iti taonga - 8 MHz.

Takekore ki te mea e te mahi taonga i taua whawhe ka waiho rawa memeha? Heoi, ka taea te taua gimmick hokohoko ki a koe whakairi ake ki runga ki te GeForce GTS 450 te NVIDIA utu teitei tūtohu. He ōrite ki te tauira paerewa te tahi atu āhuatanga.

mōkī tirotiro

tākai te kāri ataata i roto i te pouaka iti ātaahua. taha Matau anake ngā te kaiwhakamahi o te ingoa tauira, te rahi mahara, a rave rahi hangarau NVIDIA kamupene. Tenei ko reira taea ki te kitea he kupu kāri NVIDIA GeForce GTS 450 e whakaratohia te ki te pūnaha tautauā ake, te matua o ai hanga o parahi te.

e hoki mōkihi muri kore pikaunga te kaiwhakamahi whakaahuatanga ngā NVIDIA GeForce GTS 450: kua aroaro whakaritenga konei anake te taketake tino. Tata te rohe katoa e nohoia e te tuhinga pānuitanga i runga i hangarau kamupene. Haere ki te mea e me whai i te wae pūnaha supply mana te katoa putanga o 400 Watts, a ki runga ki te raina 12V ki te hoatu 22 wae iahiko.

I tua atu ki te pūurutau whakaatu i roto i te mōkihi, ka taea e kitea e koe:

• Taiaho kōpae ki etahi taputapu whai hua mo te NVIDIA GeForce GTS 450, he reira i runga i te puku hoki te taraiwa.
• Whāurutau DVI-VGA, miniHDMI-atanga, me te waea e taea ai e koe te hono i te kaha ki te kāri ataata apatoko mana wha-titi.

E kore e taea e tatou te mea i tukua te tangata taonga, engari i roto i te whānuitanga utu rite whakaaro te ki te waiho i te paerewa i whakaritea. ka kia nui mō te mahi whakamarie kaiwhakamahi Simple o tenei katoa. Ko te huakore Ko te kore o šli-piriti, engari kia tuhia te reira e ko te tata tonu tenei huānga wahi o te huinga katoa o te kaupapa, ki te he te reira e rua tūhono PCI Express.

kāri Video NVIDIA GeForce GTS 450 whakaratohia te ki te maha o atanga paerewa mō ngā pūrere tūhono (e rua DVI-ahau me kotahi paku-atanga). E ko, e taea te hono te pūtukatuka whakairoiro ki te aroturuki e toru i te wa ano kahore te hātepe.

wāhanga hiko

Ko te iahiko tāngia poari he kahore rerekē i te nuinga o NVIDIA whāurutau hanga i runga i te maramara taua kāri whakairoiro. I te taha ki te hoki o reira e wha maramara mahara, e tangohia atu ana e ratou o tetahi tautauā. He aha i whiriwhiria Engineers tonu te tahora rite te mea ngaro, no te mea ka taea te taha ki mua ki a koutou whakaturia te IMS rite reira. Ano i runga i te pūmana whaiaho hoki. Ka rite ki tuhia i mua, te mana e whakaratohia ana e te tupare PSI Express, iti hoki NVIDIA GeForce GTS 450 (ngā ataata rapu e hono ono-titi tūhono mana).

Ko te wahi pokapū o tetahi pūrere taua - te matua whakairoiro. Ko tōna ingoa - GF 106, me te hangarau tukanga - 40 nm. Kei roto te reira i te pūtukatuka 192 shader, poraka rasterization konei 16. Ki raraunga utu ki te mahara whakamahi te pahi moka-128.

Ko te nui katoa o te mahara ataata - 1 GB, tutuki nei i te huinga o waru iahiko integrated. Tohu maramara ta e rave ratou i roto i te whanaketanga o te kamupene Samsung. pūmahara wā uru - he hawhe nanosecond. Ki te tātai tatou, i roto i te ariā, ka tukua tenei ki a ratou titaria ki runga ki te 4 mano mekahera. I te tīmatanga, whakaturia te kaihanga o tenei tawhā te i te taumata o 3600.

pūnaha tautauā

I tua atu e kore e pā he rerekē i te nuinga o ngā pūrere rite i hanga i runga i te GPU taua, mā te whakamahi i te pūnaha tautauā ritenga te mahi o te wheketere overclocking te kāri ataata. Kei reira o te casing kirihou, te diameter tahi o 8 cm me te heatsink konumohe ki te matua parahi. Ko nga āhuatanga konganuku i roto i te whakapā anake ki te pūtukatuka, i te kore e te maramara mahara me te kai matao atu i roto i tetahi ara.

Me kï reira e hangaia te kāri ataata e kia e heke te auautanga te kawenga e heke aunoa me tenei taea e ki te whakaiti i te kohi mana me te wera. mahi te pūnaha i te taumata o te BIOS, whakaturia i roto i te NVIDIA GeForce GTS 450. E kore e te atekōkiri pā te āhuatanga.

Hei arotake i te whai huatanga o tenei huarahi, whakamatauria te kāri ataata i taputapu FurMark. whakatikatikanga aunoa o te tere tahi i kawenga mōrahi tukua ki te whakamahana karihi kore ake atu i te 60 nga nekehanga. Ko te mea ngā, ko te e kore ko te tahi whatu i tenei wa neke atu i 17%. Nä, ko te taumata reo i whakaiti. I muri tautuhinga tere ā-i 100% pāmahana hinga paku, i 2-4 anake nekehanga, i roto i te taime tino ohie, Heoi taringa tonu mahi te taua ata.

Anake kotahi mutunga: he kuware te hoahoa pūnaha meangiti, engari e te reira i ona mahi rawa te pai, te whakaatu i te taumata haruru iti.

mahinga petipeti

NVIDIA GeForce GTS 450, e kore he āhuatanga o te whakaaro i, a ka whakauru he kāri ataata ki te kaha mahi toharite, whakaatu te taumata iti o te mahi tūmanakohia. Factory overclock hoki e kore e pā te maha o kaka i roto i te taumata, me te i runga i te taumata o ngā kēmu FPS.

ka waiho ngā pūrere nui ki te whakahaere i tetahi kēmu hou, engari he tokomaha nui o ngā tautuhinga whakairoiro i ki kia whakawhiti ki iti reo ranei.

whakaterenga

Ka taea te whakamahi overclocking kāri whakairoiro MSI Afterburner whaipainga. Ki reira, tere tukatuka taea te nui haere ki te 950 MHz, i.e. 15%, me te auau mahara - ki te 4690 MHz (30% hua). Ko te tino mīharo mea ko e te whāurutau i muri katoa i te huringa ko kainga, ahakoa te maramara Kāore te matao o.

O te akoranga, i tetahi hua i roto i te auautanga ka arahi ki nui haere te wera me te rapu utu atu te mana, engari ka huri i whakapainga mahi nga tautuhinga whakairoiro ki iti ki āhua, me ētahi wā ki runga ki tiketike.

mutunga

kāri Video NVIDIA GeForce GTS 450, whakaritenga hangarau e kore e taea te huaina kaha - te reira he whakataetae nui ki kamupene hua o AMD, pērā i te HD 5750 me 5770. He pai hāngai mō ngā kaiwhakamahi e kore e nei tono rawa i roto i ngā o te auau.

Ko te utu mo te whakatere whakairoiro he iti tiketike rawa, engari no te mea o overclocking pūmanawa, me te pūnaha meangiti ata, e kore e taea e huaina tino tenei koha.

NVIDIA GeForce GTS 450. mahara Palit GDDR3 me

kua tukua Palit he kāri ataata e kore anake ki te maramara mahara GDDR5, engari GDDR3. Kua Ko te utu mo te hua rite kua heke e te tuatoru. Ko te whakaaro ki te whakatū i te pūurutau pai puhoi GDDR3-kongakonga e kore ke anake, engari ano hoki i tautohetia. Ka pānui i runga i te pouaka te ingoa tawhito, ka taea e te kaiwhakamahi te hoko i tetahi hua, te mahi o nei aroaro i roto i te taumata tino rerekē.

Mai i te tauira tonu i roto i 3D-tono, ano he takamuri hua i muri i te 30-60%. A ki te utu kore i hoki noa riro tenei āputa te overclocking mōrahi. e kore e tukua te kaha ngoikore o te maramara mahara ki tae te uara FPS taua, ara, ki te te pata overclock i runga i te 30%. Mahinga rerekētanga i waenganui i te tonu, me te tauira huia-iho he 15% i roto i tata katoa whakamātautau.

he pai hoki ngā kaiwhakamahi e kore e haere nei e ki te whakahaere i ngā tono rauemi-kaha, engari te kore ka hua i roto i te hiahia i te penapena o Finance ki te tāuta i te tautuhinga te nuinga o kēmu i runga i nga reiti i raro i te hua taua.
