Te Radeon 6970: tirohanga whānui, ngā āhuatanga, rite ki te whakataetae, me arotake

Radeon HD 6970 - kāri whakairoiro, AMD, tukua i roto i te Hakihea 2010. Ko tōna hoahoanga ohie hoahoa o pūtukatuka awa, a whakaratohia ratou ki te pai nui.

hītori tauira

I roto i te 2008, kua whakawhanakehia AMD ka tukua te Radeon HD 4000 raupapa, hurupoki R700 ko Ati Technologies waitohu. Pea, whakamahi tonu maha iwi reira i roto i to ratou PC. Kua whakakapia R700 hoahoanga roa-tatari te R800, i mea whariki te ara mo te lineup AMD o te Ati te Radeon HD 5000. Ko te peara ko te HD 5870 kāri raupapa, whakaurua i Mahuru 2009. ngā reira o 2.15 piriona transistors ka ko he angitu, toe tino nui tauira kotahi-pūtukatuka hoki e pā ana ki te 15 marama. Whakakapia i te mutunga o 2010. I te wa i reira tetahi o nga kāri pai i roto i tona whānuitanga utu e korero hoki iho.

ka mau Nvidia o e pā ana ki 6 marama ki te ahi hoki te tuku o GeForce GTX 470 me 480, a tae noa ka he tokomaha i whakapono e kore i ora ia ki runga ki tūmanako. I muri whakahaere he torutoru tere motu utu, me te pai ake kāri tautoko atekōkiri ki te hanga whakataetae. Atu tupu GTX 460 GF110 hoahoanga me te parakore i āwhina te hanga i tētahi hua taea, ka apu te ara mo te tauira e whai ake nei, ara te GTX 580 me 570.

Na, kua patua ana AMD HD 6000 Oketopa 209 th, haere i te tukapaku, ki te HD kāri whakairoiro 6870 rite te counterweight ki GTX 460, te uara o e na ko $ 240. Ko te tauira whakamīharo, ki te kahore hoki te tōrangapū e whiwhi ana o te ingoa me fakamanatu 'tamau o te kaiwhakanao i kore ko reira he whakakapinga mo te tauira 5870-th. Tīmata ki tenei raupapa, me i meatia mana Ati Technologies waitohu mo te whakaaro o te hononga ki waenganui i ngā hua whakairoiro i AMD me ona tüäpapa rorohiko. Nä, ke te hoahoa logo.

I muri i te roa poto, i tukua ai te Radeon HD hou 6970 2GB. hanga whakairoiro pūtukatuka, hurupoki Cayman te ake o 2,64 piriona transistors, i te mea 23% neke atu i roto i te tauira 5870-th. Ka rite ki te GTX 570 me 580, e kua pai ake putanga o te GTX 470 me 480, kua HD 6970 riro te putanga hou o te tauira 5870-th.

Ngā Whakahōunga 6900 Raupapa

Ko paku rerekē nui-mutunga hoahoanga Cayman, whakamahia i roto i te raupapa HD 6900 i Barts, Räkau i roto i 6870 th me 6850 th tauira. whakamahia te reira i whirihoranga VLIW5 HD 5000 e ngā SIMD ki wha ohie, me 1 wae tukatuka awa matatini. kāri ataata 6900 Series VLIW4 rerekē whirihoranga, i roto i nei whakaritea te rere tukatuka e i roto i ngā rōpū o te 4 poraka ki te rēhita whānui. I whai ratou katoa wāhitanga rite, 2 o ratou (3 me te 4) mahi mahi motuhake. E ai ki te kōrero i te kamupene AMD, VLIW4 whirihoranga whakarato tukatuka mana kore iho VLIW5, i te whakaiti i te rohe kongakonga e 10%.

whakarato pūtukatuka Keimana te taumata tiketike o te parallelization whakaritea ki Evergreen / Cypress hoahoanga whakamahia i roto i te HD 5800. Barts GPUs e vahi i roto i waenganui i, mai kua ratou he taahiraa i mua i Cypress whakahaere pūmana rere takitahi mō ia o rua SIMD-poraka. tītipi Keimana i atu noa kōwhiringa whakawhetai ki te engines e rua ki GPE me whakaaro o ia o ratou ki te SIMD-kōwae. Tenei te tikanga e inaianei kua rua wae rōpinepine pai atu rite whakaritea ki te tetahi i Barts te hoahoanga. I roto i te HD 6900 kāri whakairoiro, kia taea te tino whakapai ake i te mahi rōpinepine. E ai ki a AMD, nui haere te reira 3-taiepa rite ki te HD 5870. I tua atu, e rere ke ano Cayman architecture engine tukatuka tāhuahua tënei o 128 ROP Z / Takituhi, 32 tae ROP, me ngā mahi tau tōpū moka-16 tata rua rite nohopuku me te 2-4 -fold ake i roto i te tere o te bit-32 ngā mahi māngi-ira.

architecture Cayman

Te whakawhiti i VLIW5 VLIW4 ki ake rorohiko AMD mana: whaiti māmā SPU ki te whakamahi i te mahi tonu, FP64 whakarei ake whakaritea ki te hauwhā-FP32, a taea wāhi ora hāngai SIMD atu. Otiia ki te ko Cayman he whakamātau nui ki te riro i te tunga i roto i te mākete o te rorohiko ataata, me te Katikati atu he wahi o te keke i NVIDIA, na kia meatia e te reira, nui atu i te tāpiri noa shaders hou. Na reira, kua takatakahi AMD ki te whakapai ake i te taumahinga o tona pūtukatuka whakairoiro, kia e taea tū reira he riri ki te hoahoanga Fermi.

Ko te āhuatanga matua o te Cayman he whakaritenga tukutahingakore. Ko te wā tika whakamārama ana he aha hanga te kāri. Te Fermi NVIDIA whakaurua tautoko mō otaota whakarara, i ngā te wāhi ki te kawe i roto i tātaitanga o te maha mongamonga o waehere i te wa. toutou AMD te huarahi NVIDIA, engari haere atu.

Whāiti te hoahoa Fermi ko e ahakoa taea te hoahoanga ki te whakamahi i otaota maha, ia o nei me mahi e te pūtukatuka awa kotahi. tono Independent, hei tauira, e kore e taea e puta ratou ake waehere me te rere i te reira i roto i whakarara, me te pau GPU whakakā horopaki i waenganui ia ratou. hangaia pānui tukutahingakore i AMD te ki tukua awa motuhake me tono whakaputa waehere kia e ka mahi i roto i te whakarara. I te iti rawa i runga i te pepa, homai ana e ia ki a koutou i te painga nui (he utu rawa horopaki pana), i ko ki nui Fermi mahi.

Ko te parau tumu o te whakaritenga tukutahingakore ko e te GPU huna etahi mōhiohio e pā ana ki tona āhua tūturu o ngā tono me te waehere, e, i roto i te pānga, arahi ki te marikotanga o te rauemi GPU. I muri i te katoa, kōrero katoa wahi o te waehere e mahi i te reira i runga i to koutou GPU ki tona tūtira whakahau me te wāhi wāhitau mariko tūmataiti. hünuku te reira i te pikaunga i runga i te GPU me taraiwa, ko te payoff ko e te reira pai atu i te whakakā horopaki.

titau whakaritenga tukutahingakore tautoko API. DirectCompute Ko te paerewa pūmau, a kore e tenei āhuatanga tautoko, i te iti rawa i roto i te putanga 11-rua. Na reira, whakatinana whakaritenga tukutahingakore te rite te toronga o OpenCL.

pā te toenga o nga whakapainga ki te mahara AMD me mahi keteroki. tonu te hoahoanga taketake nga taua i konei, engari i hanga etahi huringa iti i roto i te tātaitanga o te hua. rokiroki raraunga Local e wātea ana i ia SIMD, he taea ki te hipa i te raupapatanga keteroki me te rokiroki raraunga ao i te pānui hāngai inaianei. ka Cayman te kōwae 2 uru pūmahara hāngai, i pai ake lau, ka tuhituhi tere, tuku ki a koutou te mahi ngā mahi i te 2 i roto i nga aronga.

I te pae hopea, i reira he iti shaders pānui vitiviti. Ina whakaritea ki Cypress, Ka taea e Cayman whakaiti i te maha o ngā mahi mā te whakakotahi ia ratou.

hoahoa

roa kāri he 27 cm, i te mea angamaheni o hou tauira tiketike-mahi. Hei tauira, HD 4870 roa X2 ko 28 cm, rite HD 5870. HD 6970 taua āhuatanga ōrite GTX 580. rite tona mua, AMD Radeon HD 6970 hangaia te whakamahi i te tukanga 40nm, engari te kamupene tapiritia tetahi 486 miriona transistors, hua he aha te kongakonga rahi kua nui haere e 16%. rere GPU matua i 880 MHz, i te mea 3.5% ki runga ake i te HD 5870, me te GDDR5 paku hoki tere i te auau o 1375 MHz. auau mahara, i honoa e ki te bit-256 pahi, HD 6970 homai te hōkaiipurangi ariā o 176 GB / s, i te mea he painga 14.5 ōrau i runga i te HD 5870.

HD 6970 He rerekē i pakeke te tauira 5870-th hoki whirihoranga taketake. Ki te ko te whakamutunga 1,600 otaota 80 me 32 TAU wae rasterization, te awa tuatahi pūtukatuka riro 1536, te wae kakano 96 me te taua 32 ROP (otaota 4% raro me 20% atu TAU).

Hoki urupare kaiwhakamahi, whakamana te tātari bilinear kakano wāhi tihi kei i te tere o te 84,5 gigatexel / s, a te whakakī pika - 28.2 RN / s. Mahinga o 2.7 teraflops. hanga te scene e toru-ahu kei i te tere o te 880 miriona taparau / hekona. E tautoko ana te kāri rua-awa anō HD-ataata, me te he pūmana integrated audio.

Roto te take ko te poari taiawhio tāngia ki te rohe GPU o 389 mm ² i roto i te pokapū. whakatakotoria a tawhio noa pūtukatuka 8 2-GB Hynix GDDR5 tītipi mahara ki te auau raraunga iti o 6 Gbit / s, 0.5 GB / s ake auau whakahaere kāri. faingataa Mā te GDDR5 tere tiketike e fifi i roto i te hanga i te pahi mahara pai e i te pānga i runga i te tauira. hanga AMD kua ahu whakamua i roto i te whakatutuki i te 5.5 Gbit / s mā te whakapai ake i te hoahoa o te papa iahiko tā, engari ake i atu te mea koretake te tere, ki te anake te mea o te hoahoa o te pahi moka-256.

mātao

Meangiti pūtukatuka he nui ruma nui konumohe whakamahana vaporization tënei o nga paraharaha 39 o roa 13.5 cm, whanui 6.5 cm, me te tiketike 2.5 cm. I whakatinana tuatahi hoahoa evaporator i AMD Ati Radeon HD5970 me te tono i roto i NVIDIA GeForce GTX 570 me 580. Hei whakamutunga, mātao te tahi whakamahana 75 x 20 mm, e kumea hau i roto o te whare, me te pana i te reira i roto i ki te muri o te kāri.

Hoki urupare kaiwhakamahi, he rawa ata mo te wahi tino o te makariri, tauturuhia kohi mana iti (W 20) i roto i te aratau mangere. I roto i te kēmu, he powhiriwhiri, o te akoranga, whakatere, ka uta i te kāri pau ake ki te 250 Watts. Ko 33% neke atu i hiahiatia Radeon HD 5870 tenei, engari tae noa ki te hua i roto i te kawenga wera e kore e whakanui i te taumata ngangau ki uara Kāore.

E kopakia ana te whakamahana me te tahi i roto i te whare i āta hangaia e hipoki ana i te kāri whakairoiro katoa. AMD Ko te mahi noa i roto i te hoahoa o ratou tauira tino whiriwhiri. E ai ki te urupare kaiwhakamahi, he hoahoa rite ratou, mai i whakarato reira tiaki pono mo koutou pūrere. Kua mahi NVIDIA ano i roto i te mua mo taua ratou kāri whakairoiro tino utu, te GTX 295 rua-GPU, ahakoa atu ona hua tino nui (hei tauira, te GTX GeForce 580), kua mutu tenei whanaketanga ki te tono.

hononga

I roto i te tikanga ki te whakarite kāri kaha rawaka, kua whakaturia AMD te 8- me 6-titi tūhono PCIe. Ka taea te kitea he otinga taua i roto i te HD 5970 me GTX 580, t. Ki. Kei te ana tēnei whirihoranga te tikanga e whakamahia ana i roto i te tauira e pau te rota o te pūngao. O te akoranga, HD 6970 tautoko Crossfire, a na i runga i te pae paerewa, ka taea e kitea e koe i te rua o tūhono ki te hono rua, neke atu rānei ngā kāri. Muri ki a ratou ko te pana e taea e koe te whiriwhiri i waenganui i 2 BIOS. meatia tenei e ki te whakapai ake i te tika o te tauira i roto i te take o te kore o te mahara flash. I tua atu, ka taea e koe te whakahaere i te GPU mā te whakamahi i te pūnaha tārua, a ka whakawhiti hoki ki te tuatahi, me te anō-tuitui i te pūmanawa pakaru. I mua ki tenei, e kore e AMD tautoko taeatuhi BIOS rerekē, engari kua meinga tenei whakatinanatanga te huringa ngā.

Kei te tū te toe tauranga i runga i te rōpū tāuru / tāputa. kāri ataata Tohutoro tauira rawa ki rua rua DL-DVI-tūhono, rua-tauranga Mini-DisplayPort me atanga. E tano ia tapao e tautoko te tauira 6970-e ahau he taumira ake mōrahi ki 2560 x 1600 i runga i te 3 te aroturuki. He hub ki te-awa maha, te whakamahi i te paku-tūhono DisplayPort 1.2, ka taea e te kāri e mahi ake ki ono ngā whakaaturanga. Ka rite ki 5870, taupokina te taha ki muri o te pūrere e ki te paraharaha whakarewa. Ahakoa i reira he kore wāhanga e rapua e te parururaa, pai riro te whakatau i ngā kaiwhakamahi, no te mea taea reira ki a koe te tango i te kāri, kaua e manukanuka ki te kore ki te pa ki nga titi koi.

Ahakoa te rahi whānui o te HD 670 Ko tata ōrite ki te tauira 5870-th, arotake kaiwhakamahi, AMD karapoti hoahoa e kore he tino pai ka tae mai te reira ki te mahi i roto i te aratau Crossfire ki whakapumautia 2 kāri muri. tu i roto i te whare 5870 th moka i roto i te pokapū, e pupuri i te rongoatia rangi i ārai papa pātata. I roto i te 6970 E kore ko te papai taua tuatahi, a taea tata tutakina te kāri runga, i runga i te āhua o te tāuta i te reira rānei. Ka rite ki te hua, e whakatika te pāmahana, engari e kore e ki te uara tino. AMD o whaitake ki te ako i to ratou whakataetae i NVIDIA me huri noa te tahi ki te tohatoha atu wāhi e pai tukua ia ki noa "manawa." E tohe Kaiwhakamahi ki te tāuta i te kāri whakairoiro, ka mahue i waenganui ia ratou tae noa ki taea, ki te te kaupapa me te tahuhu tukua reira.

mutunga

Te āhua e te HD 6900 me GTX 500 tukurua ia atu. Ki te he torutoru ngā rerekētanga matua, o te akoranga. puta NVIDIA hua i runga i te mākete i roto i te wa, ka whakamatauria ki te kia tino whai hua i roto i te aroraa ki tāwhai tauira AMD. GeForce GTX 480 ko tere te kāri whakairoiro kotahi-pūtukatuka, te GTX 580 a puritia te karauna rite ko reira nui rawa hoki te Radeon 6970. hāngai te utu ki te utu o te tauira GTX 570, me motuhake 580th runga HD 6950. anake i te timatanga o te tau i muri mai, kua AMD he wāhi ki te hoki mai tauākī painga i roto i te mahi mā te tuku i 2 HD 6990 kāri raupapa, hurupoki Anatīa.

Radeon HD 6970 haere ringa i roto i te ringa ki te GTX 570, a kua te utu hokohoko tūtohutia hoki tenei kāri kua whakaturia i $ 369, i ki te GTX 570 waiata i $ 349. Ahakoa te meka e e rua tauira tino rerekē enei, whakakitea e ratou te taua mahi toharite i roto i ngā kēmu maha, ngā kaiwhakamahi whakamātautau i roto i te taumira o 1920 x 1200. hoki te wahi tino he iti rawa te rerekētanga. Radeon 6970 i roto i ētahi wā ko te 20% tere atu i te GTX 570, me i roto i etahi atu - e pā ana ki 20% pōturi. Ko hoki Energy kohi e rua kāri rawa tata, e whakaatu ana rite taumata o tōtika whakahaere. Na reira, ko te HD 6970 Ko te rerekē pai ki te GTX 570. E kore te mea ngāwari te whiriwhiri i waenganui i nga kāri e rua, engari te tika ki te hei i tetahi otinga, homai ratou utu, me te mahi.

Ina whakaritea ki ētahi atu tauira, pērā i te GTX 580, 6970-e ahau i roto i te toharite 15% pōturi, engari te mea utu he 30% hekenga, me te te GTX 570, e tuku he utu noa pai. Kāri, e tōtika whakakapi te HD 6970 - ko te HD 5870. I te pūtake o ngā raraunga whakamātautau i roto i te taumira o 1920 x 1200 taea te mea e te HD 6970 he 24% tere, me te 10 anake% utu atu i runga i toharite. I tua atu, i te tōtika tauira pūngao kua hoki kua pai ake. Nui ake te mana kohi i 16% e homai he atu 24% mahi. E tano ia tapao e te Radeon 6970 titiro te iti pai atu i te GTX 570 i roto i ngā kēmu Stalker: Call o Pripyat me tangata ke vs. Kararehe kino, e whakamahi rōpinepine. Mua ki tona whakataki, kua a NVIDIA he painga nui i konei.

Tairanga, whakarato e rua te kāri whakairoiro te taumata tino o te mahi me te uara, hanga i te pai rawa i waenganui i te rua i te wa kotahi ngāwari me te matatini. Engari ka tika tetahi whakatau.
