Nvidia GeForce GTX 470: ngā, te arotake

Kua NVIDIA kua he roa rawa te wa, ki te hoahoa taipitopito hoahoanga tautoko i te whakataetae tika o ngā hua hangaia. Ko te kupu, i roto i te nuinga rawa o ngā take e pā ana ki e rua nga tau pau i runga i te kamupene ki te neke i tetahi raupapa ki te muri.

i whakaroa e kāri tuku GTX 470 whakairoiro no te mea i takoha ngā ki pakeke nui ki te tukatuka hoahoanga, i reira ko etahi raruraru ki production, faifai hanga i taua e rawa nui wera i roto i te akoranga o ratou mahi i te maramara. Ko te kupu, noho te huringa tata rite te taua, engari kua riro mai te kāri o mua tata e rua nga tau. Ko, ahakoa, tukuna GTX kāri 470 i kī tuatahi kia huaina ki tetahi rangatira hangarau o tona wa. Käore e kore e te hunga pera ratou i.

GeForce 400

I ngā wā, e whakaratohia ana NVIDIA te i te wa ano nga kāri e rua whakairoiro, te GTX 470 me 480, engari kei te he atu noa te reira i te putanga tuatahi i roto i ngā kaiwhakamahi i teie mahana.

tonu tohunga tahuri ratou whakarongo ki te maha o transistors, i i whakamahia i roto i Fermi. Mā te tenei tawhā taea te autaki korero pehea pai ko te maramara hou, no te mea ko reira nui atu i rua rite hua he mea whakarite ki te tino nui o mua o te kamupene, me te wā kotahi me te hawhe, nui atu i roto i te Cypress atu hou, e ko he rawa, he hua tino pai.

O te akoranga, kei te tika kitea tenei ahua i roto i te wera. I roto i te tukanga o te GTX 470 i hanga ai ki te whakamahi i te tukanga hangarau 40-nm, ai te rerekētanga i roto i te mōkihi waiariki, me te taua whakaaro ko āhua te rite te rerekētanga i roto i te maha o transistors.

āhuatanga Hangarau

I te tīmatanga, i whakaritea e te reira ki te whakamahi i CUDA-512 pūtukatuka, engari i runga i te wā, i hoki whakamuri tenei whakatau, kia i paku heke te ahua i roto i te tikanga ki te whakaiti i tohanga wera, me te whakapiki ake i te tukua o te maramara tino mahi. Heoi, te mutunga ka tonu kia tino utu mo te nuinga rawa o ngā kaiwhakamahi te kāri.

meka ke i ai te auautanga mahara noa i roto i te tauira tino hua iti atu i te whakataetae otinga HD 5850. Ko te katoa hōkaiipurangi mahara runga ake i GeForce GTX 470, engari e tika ana ki te meka i whakamahia reira maramara tere, tapae te taea o tona whakaterenga atu .

Āhua o te mahi i te reira i roto i te kēmu?

ngā tauira e rua tautoko mō te DirectX 11. Kia timata te mākete ki puta Evergreen tauira kāri whakairoiro, i reira i tata tetahi mea i runga i te mea i taea e kua i ki te whakamatautau i te kaha o tenei pūrere, engari ki te tuku o GeForce GTX 470 āhuatanga e kore kua puta ke. Games e taea te tautoko i te hou te API, i taratahi take, engari mo te wā, o te akoranga, i tukuna he maha nui o kaupapa rerekē, hoki nei te whakamahi o te kāri ataata taua. I tenei ra nei tona whakamahinga he tino pai hoki te nuinga nui o ngā kēmu, me te mea e kore e taea te takaro te hou i ngā whakaritenga mōrahi, te reo, ranei i te iti rawa i te iti ka mau tonu te reira pūmau.

I mua, ua faaoti te kamupene ki te bet i manakohia o te heke mai i te mä koutou GTX NVIDIA GeForce 470 ki te mahi i taua whai wāhitanga whakaekea whakamutunga o DirectX ki, me te tokanga makehe ki GPGPU.

Ko te hoahoanga o te maramara hou

whakamahia te pūrere hou i te maramara ki te hoahoanga hou i huaina GF100. I para tuatahi, i reira ko etahi rerekētanga nui i to mua ', te hoahoa o ngā tūemi hou noho scalar, kia i reira etahi fakangatangata. Paku ke te hanganga o pūtukatuka whakaaro whānui, i whakaritea e te reira ki te ngā i roto i te poraka tika nui. I roto i te tauira GT200 huaina taua wae i te TPC, me ia o ratou ngā nga oko tika katoa e kia hiahiatia ai ka mahi ki whakairoiro, hāunga poraka rasterization. I roto i te heke mai, te kamupene hohoro tīmata hanga he rota o putanga Outlet o NVIDIA GeForce GTX 470, i reira i rānei momotu whakarerekētia ranei taua poraka.

I roto i ia i taua poraka o te tauira maramara o mua hakari e toru (multiprocessors tarere) SM, me waru wae kakano me te keteroki taumata tuatahi o 16 KB. I roto i te poraka o nga whakaaro hou, i roto i te tahuri, kotahi Engine Raster kua whakamahia, me wha SM, i roto i ia o nei te hakari ake keteroki me te kakano wae. I te maramara ano, i reira he wā kotahi te poraka e wha i roto i te nui whakarato te kaiwhakamahi 32 pika ia karaka.

multiprocessors Streaming

Ki te whakaaro tatou te pūrere i te taumata o SM, ko tino nui te rerekētanga, mai i te mea kua tukua e ia i te GTX NVIDIA 470, kua tohu maha tohunga i roto i taua i reira he SM nui nui, me te motuhake. I roto i te mua, i puta ke whakatupuranga hakari kāri 8 SP, me te 2 SFU, engari inaianei ratou tokomaha, me te ōwehenga, ai roto i ia pūrere reira i runga i te 4 SFU, 32 CUDA Core, 16 me ngā waeine Utaina / Store.

I te toru o ia o enei multiprocessors whakatupuranga i reira i te maha o ngā pūtukatuka kakano me te mahara ngā e whakarato rōpinepine pūmārō.

Nā ki te meka e nga pūtukatuka kakano, me te te multiprocessors mahara keteroki hāngai katoa kua oho i roto, i taea ki te whakatutuki i te mahi o enei whakaaro nui atu pai nga ngā. I whakaritea e te reira ano ki te rework radically te hoahoanga ā o enei whakaaro, ki te whakapiki ake i te auau o ratou mahi, me te kaha e toru ngā wā i te rōrahi o te taumata tuarua o te mahara whakamahia i roto i te tukanga o te texturing.

mahara noa

Kua mahara tiri kua ngā ki te keteroki L1, hua i roto i te hāngai mahara riro tika tohaina, i runga i te aha te huru o te mahi whakamana te i te kau i te pūrere rānei. I mua ngā mahara noa anake 16 KB, Heoi, i tenei wāhi, i runga i te momo o te mahi rānei, e tuwha te taputapu 64 KB o te mahara. Ki te i te kau, he maha nui o whakataunga tinana, na nga KB 48 o te GTX kāri mahara 470 tohatoha ki L1. Ki te ki nga tukanga rerekē te nui nui o te wā e rapu mōhiohio tauwhāiti, kei te rongoa reira i roto i te mahara ngā. I roto i te tahi atu mea whai hua mō te GPGPU he hoki e toru ngā wā i te nui o L2 keteroki i roto i nga Whakatakotoranga Hua GTX 470, pera atu me te atu haere atu i roto i rite ki te whakataetae.

rōpinepine

Rōpinepine Ko tetahi o nga āhuatanga matua o te kāri Radeon HD 5000. kāri Video NVIDIA GeForce GTX 470, i roto i te tahuri, whenua pai mo te whakatinanatanga o tenei hātepe papatono.

Ko te API DirectX 11, i reira he tautoko hoki etahi "mahere displacement" e he kakano rōrahi. Ko te kupu, ia pika kei roto i te ahua o te kakano, ka whakatau i tona tiketike. Kei te tono tenei kakano ki te kēmu i roto i te tikanga ki te hanga i te whakapakoko atu taipitopito.

Tenei he wahi mai i roto i te rōpinepine, rite rawa nei te ki te GTX 470 Overview o te hātepe whakakitea e hanga e te te mosaic katoa i te pae kotahi. whakamahia tēnei hangarau kua ahakoa o nga mahere displacement, engari ka taea e te pānga tino mīharo kia tutuki noa ki te kei te whakamahia tahi ratou. Ka heke nga tihi o hanga taparau piki ki tetahi he teitei, mau mai i te pūnaha ki te tauira i tohua e te ruma kāri ranei.

He aha e nga painga?

I roto i te meka, i whiwhi ai te tauira te tino ōrite ki te Moananui paerewa tiketike, te tau'a ore i te wa ano, Moananui iti, ka hoatu e t. Ki. Reira nga ngā tika, me te atarangi tika, te haamau'araa i te kupu he tikanga katoa o nui iti rauemi.

I roto i te mau parau te tahi atu, NVIDIA GTX 470 āhuatanga pērā e taea hohoro te uta i te reira i te kāri tauira mahara, i te kore e te muri i ki te kawe i roto i utanga, me te unloading whakaurunga ki ētahi atu taumata o taipitopito, he aha i pono hoki ngā pūrere whakatupuranga o mua. Kua kawea tukanga katoa i roto i faafariuraa tika i roto i te kāri i roto i te ngā ngā tukanga e whakarato scalability tawhiti nui. Tei runga i te aroaro o te mana rorohiko rawa free ka waiho ofi ki te mahere displacement ki te tetahi tika, i te mea tino nui i roto i ngā o āhuahanga mahi GTX 470 arotake Kaiwhakamahi whakaaro e te hangarau tino whakapiki i te mahi whānui o te rorohiko i roto i te mahia o tukanga whakairoiro matatini.

He aha ngā kaiwhakamahi e mea?

Urupare i ngā kaiwhakamahi, te whakahou i tō rorohiko mā te tāuta mahere whakaahuatia tohu e muri i te whakahōunga ko reira taea ki te hoatu i roto i te kēmu katoa tautuhinga mōrahi. kihai i tuki te kēmu, kihai i kahore frein kitea.

O te akoranga, he āhuatanga o te 2010-2012 enei urupare, i te kau kei te kore te kāri whakarato tona rangatira ki taua taea mure ore. Otiia i roto i taua wa hangarau kua tupeketanga mua, a ka haere i enei kēmu, i roto i nei e taea anake te takaro he taua kāri whakairoiro i runga i ngā tautuhinga iti.

3D Vision

hangarau 3D riro tenei ra tino whānui, mai i televisions me te aroturuki i mutu. Ahakoa te kamupene kua roa AMD kua take ona ake mōhiti, me te te pūmanawa e tika ana, e taea ai te kaiwhakanao kāri ataata ki te whakaatu-kounga teitei whakapakoko stereoscopic.

ngā te āhuatanga GeForce GTX 470 hoki te kaha ki te whakamahi i tenei hangarau, a ahakoa te meka e te mea he nui mahi mohio whānui o te gameplay kiriata ranei he tino rerekē.

Ko te huinga katoa o te taputapu e whakaratohia ana e ngā kāri ataata rerekē me te API, he pakeke nui ki te ako mō ngā kaiwhakamahi noa, me te kupu e whakaaro ki te kia tino maumau ki te kahore tetahi e whakamahi i te reira i te reira. Ko reira hoki tenei take i e kua hanga NVIDIA he wehenga motuhake e mahi ki ngā kēmu hou. O te akoranga, kua hoatu tonu whakarongo ki te kaupapa angitu tino, kua oti nei te whakapumautia mahi tahi whaihua, no te mea te mutunga riro te kēmu iho nui tere me te ake ataahua i roto i te kaupapa e kua whakarewahia ai te kaiwhakamahi i runga i te rorohiko ki tenei kāri.

pūnaha tautauā

Ki te whakarite tika tautauā, kua whakawhanakehia te kamupene kāri he mātao motuhake, i te mea tetahi o te kaha tino i roto i ngā tauira tohutoro rite. hangaia te pūrere e i roto i te puka o te mīhini huri hiko paerewa, engari e te reira i te torutoru āhuatanga e tino tika tokanga makehe.

Ka rite ki te pūtake pūnaha i te tahuhu aunoa ki te taupoki kirihou piri ki reira. Na roto i motuhake pakaru waiariki, te wera hangaia i roto i te mahi o nga maramara mahara me pūnaha, kua tuku ki te anga. Mai i te GF 100, nekehia atu te wera te ki te awhina o putorino wera motuhake rima e haere mai ana ki te whakapā ki te maramara tika.

whakapā Direct pūtukatuka putorino wera ispolzuetsya kongakonga maha meangiti pūnaha, me kore e taea e huaina mārama atu whai hua atu i te paerewa te pūnaha taua. Otiia i roto i tenei take e mea ai e, ka whakawhanakehia, te GTX GeForce 470, kua whakarongo motuhake utua nga ngā ki te pūnaha meangiti.
