Le Radeon 6970: Isishwankathelo, iimpawu, uthelekiso kunye okhuphisana kunye nohlaziyo

Radeon HD 6970 - ikhadi yemizobo, AMD, wakhululwa ngoDisemba 2010. Its sesakhiwo lula uyilo iziqhubekisi emfuleni wabalungiselela ngempumelelo enkulu.

imbali model

Ngo-2008, AMD liye laphuhlisa laze lakhupha Radeon HD 4000 series, codenamed R700 kunye ATI Technologies kraca. Mhlawumbi, abantu abaninzi zisasebenzisa xa PC zabo. R700 bokwakha iye indawo R800 elide-ilindelwe, nto leyo kwavula indlela uhlelo AMD yeli ATI le Radeon HD 5000. Le perile yaba HD 5870 ikhadi uthotho, esamiselwa ngo-Septemba 2009. izilingo transistors 2.15 billion waza waba nempumelelo, eseleyo flagship imodeli olunye-iprosesa iinyanga-15. Indawo ekupheleni kuka 2010. Ngelo xesha wayengomnye amakhadi ngopfu kuluhlu layo inani uthetha ukuba ngokwayo.

Nvidia yamthabatha iinyanga 6 ukuya umlilo emva kokukhutshwa GeForce GTX 470 no-480, yaye ke abaninzi bakholwa ukuba akazange bafezekise izinto endandilindele ukuba. Emva ezimbalwa ngokukhawuleza amaxabiso amanxeba nokuphucuka ikhadi inkxaso umqhubi likwazile ukwenza kukhuphiswano. Olunye elivela GTX 460 GF110 ngezakhiwo kunye kwalungiswa banceda ukwenza imveliso iphila, kwaye kuvule indlela yemifanekiso zilandelayo, ezizezi GTX 580 no 570.

Okwangoku, AMD uye wanikela HD 6000 we-Oktobha 209, edlula ikhuni kwikhadi yemizobo HD 6870 njenge counterweight ukuya GTX 460, xabiso lazo elo ke leyo $ 240. Yaba imodeli umxhelo, ngaphandle kwezopolitiko bofanelana bephinyelene igama kunye izikhumbuzo rhoqo lomenzi ukuba akukho lilalela imodeli 5870-th. Ukuqalisa le ngcelele, kunye ATI Technologies uphawu kwenziwa ngokusesikweni ngenjongo unxulumano phakathi iimveliso nemizobo evela AMD kunye namaqonga yayo ikhompyutha. Ngako oko, batshintsha uyilo logo.

Emva kokuba delay mfutshane, oko wakhululwa HD Radeon omtsha 6970 2GB. Graphics iprosesa, codenamed Cayman wenziwe 2,64 billion transistors, nto leyo ngaphezu-23% ngaphezu kwimodeli 5870-th. Kanye GTX 570 no 580, nto leyo iyaphuculwa iintlelo GTX 470 no 480, HD 6970 waba inguqulelo maxesha yemodeli 5870-th.

Zohlaziyo 6900 Series

isiphelo eliphezulu-bokwakha Cayman, esetyenziswa kolu thotho HD 6900 yahluke kancinane Barts, wangenela in th 6870 kunye neemodeli th 6850. Yayisebenzisa uqwalaselo VLIW5 HD 5000 ebandakanya SIMD kunye neeyunithi ezine ezilula 1 umsinga processing ezintsonkothileyo. ikhadi levidiyo 6900 Series ezahlukeneyo uqwalaselo VLIW4, apho ukuhamba processing ulungiselelwe amaqela iibhloko-4 kunye iirejista jikelele. Nangona bonke banawo amathuba alinganayo, 2 kubo (3 neye-4) nokwenza imisebenzi eyodwa. Ngokutsho ingcaciso evela kwinkampani AMD, VLIW4 uqwalaselo inika amandla processing ongazukujongela VLIW5, ngelixa kuncitshiswa indawo chip-10%.

iziqhubekisi Cayman zibe kumgangatho ophezulu parallelization xa kuthelekiswa Evergreen / sihlahla lwezakhiwo ezisetyenziswa HD 5800. Barts GPUs siphakathi phakathi, ekubeni baye linyathelo elibheka phambili ukusuka sihlahla ekuqhubeni nabaqondisi flow ngamnye ngamnye SIMD-neebhloko ezimbini. chips Cayman ineenketho ngakumbi ukuba iinjini ezimbini ukuya GPE kunye nenjongo ngamnye kubo SIMD-unit siyabulela. Oku kuthetha ukuba lonke ngoku unit ezimbini tessellation ngakumbi kakuhle xa kuthelekiswa elinye Barts. Xa HD 6900 card imizobo, ngoko komsebenzi tessellation ezakunyuswa kakhulu. Ngokutsho AMD, eli nani lenyuswa laya ngesondo-3 kuthelekiswa HD 5870. Ukongeza, Cayman ngezakhiwo kwakhona iyahluka ukuqhubekekiswa injini inguqulelo equlathe 128 ROP Z / istensile, 32 ROP umbala, kunye nemisebenzi elipheleleyo phantse kabini ngokukhawuleza-16-bit kunye 2-4 -fold ukwanda kwisantya bit-32 imisebenzi lencopho-yokudada.

Architecture Cayman

Le nguqulelo VLIW5 VLIW4 ekuphuculeni computing AMD lwamandla: ayemxinwa lula SPU ukusebenzisa ukusebenza ngokupheleleyo, FP64 uphucula kuthelekiswa ngekota-FP32, kunye nesithuba basindiswe inokuthatha SIMD olongezelelweyo. Kodwa ukuba Cayman yaba yayililinge elinyanisekileyo lokufumana zintshula kuloo yokurhweba becomputing ezibonwayo isniphu off isiqwenga ikhekhe NVIDIA, ngoko ke kufuneka senze okungakumbi ukongeza nje shaders ezintsha. Ngoko ke, AMD kunzima ukuphucula ukusebenza iprosesa imizobo yalo, ukuze oko isongela i Fermi bokwakha.

Olona phawu ephambili Cayman yi ukuhlela emgudu munye. Eli gama lichaza kakuhle into eyenza ikhadi. I Fermi NVIDIA laqalisa inkxaso umphakathi parallel, okwaye kwabonelela ithuba ukwenza izibalo eliqela ikhowudi ngexesha. AMD iyaphindwa NVIDIA indlela, kodwa akuphelelanga apho.

Ukucutha uyilo Fermi kukuba nangona zibukeke ivumela ukusebenzisa umphakathi ezininzi, nganye kufuneka sinikezelwe yi single a Processors emfuleni. izicelo Independent, umzekelo, abakwazi akhuphe ikhowudi zabo uyiqalisa kwimeko nokucima ezinxuseneyo kunye GPU kufuneka phakathi kwabo. sokuhanjiswa olungenangqamaniso evela AMD yenzelwe ukuvumela imisinga ezizimeleyo kunye izicelo usike ikhowudi kubulawa ngaxeshanye. Ubuncinane ephepheni, oko kukunika ithuba obonakalayo (umxholo utshintsho kuyabiza kakhulu), nto leyo lidlule ukusebenza Fermi.

Umgaqo ukuhlela olungenangqamaniso kukuba GPU efihla ulwazi malunga nesimo bakhe bokwenene kwezicelo kunye nekhowudi, leyo, eneneni, kukhokelela ekubeni lweeHedfowuni ubutyebi GPU. Ngapha koko, yonke into khowudi lucebisa ukuba asebenze kwi GPU yakho emgceni wayo umyalelo kunye isithuba yabucala idilesi enembonakalo yenyani. Siyeka umthwalo GPU kunye nabaqhubi, kodwa kunomvuzo ukuba kungcono kunokuba uneswitshi umxholo.

ukuhlela olungenangqamaniso kufuna inkxaso API. DirectCompute kungumgangatho fixed, yaye olu phawu ayixhaswanga, ubuncinane kwi yesibini-11 iinguqulelo. Ngoko, ukuhlela olungenangqamaniso iyaphunyezwa njengokunatyiswa OpenCL.

Ezinye yokuphuculwa zinxulumene AMD inkumbulo kunye nokusebenza cache. Nakubugcisa lisafana apha, kodwa benza utshintsho engephi ekubaleni imveliso. ukugcinwa data Local ziyafumaneka SIMD nganye, ngoku iyakwazi yokucima iqela cache kunye nokugcinwa kwedatha zehlabathi ngokufunda ngqo. Cayman wayifumana unit 2 ufikelelo ngqo kwimemori, kuphuhlise ukufunda nokubhala isantya, elikuvumela ukuba enze imisebenzi ngelixa 2 emimoyeni yonke.

Ekugqibeleni, kwaba kancinci shaders yanda ukufunda. Xa kuthelekiswa ngemisipres, Cayman unako ukunciphisa inani imisebenzi ngokuhlanganisa kubo.

design

ikhadi ubude-27 cm, nto leyo ngokuqhelekileyo iimodeli oluphezulu lwe mihla. Umzekelo, HD 4870 ubude X2 yi-28 cm, njengoko HD 5870. HD 6970 milinganiselo twatse GTX 580. Ngokufanayo yayo, AMD Radeon HD 6970 yenziwa kusetyenziswa inkqubo 40nm, kodwa le nkampani wongezelela enye million 486 transistors, okubangela yintoni ubukhulu chip liye landa nge-16%.
