I-HD 7970: imininingwane yezobuchwepheshe nokubuyekezwa

Ama-video we-High-End amavidiyo awamangazi muntu, ngoba abakhiqizi baqaphela ukuthi kulabo abalandeli abaningi abazodlala emidlalweni yekhompiyutha enamandla kakhulu yesizukulwane esisha, amandla ekhadi levidiyo afika kuqala. Lokho nje intengo yedivayisi ingamisa umthengi ongenakho. Ukuheha, ukuguqulwa okuphakathi kwamadivayisi kudalwe, okuhloswe kuyingxenye ephezulu, kodwa inani labo liphansi kakhulu kunabalingani babo.

Kulesi sihloko, sizoxoxa ngomunye walawa madivayisi wevidiyo - umdlali wevidiyo i-HD 7970 kusuka emthonjeni owaziwayo owakhiwe izixazululo zabo ku-chip chip. Umgomo oyinhloko womenzi wukuthi unciphise izindleko ze-adapter yevidiyo, ngenkathi egcina amandla okudlala ahloniphekile.

Umncintiswano ofanelekile

Uma kuziwa emikhiqizweni engabizi kakhulu kaNvidia, kubonakala sengathi umkhiqizi unikezela ngokusuka kwenguqulo ye-Geforce Titan i-flagship, ungabona lokhu ngokuqhathanisa ama-chips amadivayisi nokuhlola izakhiwo zabo. Enkampanini ye-AMD ingenza ngendlela efanako ukunikeza ukushintshwa okungabizi kwe-Radeon R9 chip, kodwa abazange bakwenze. Ikhadi levidiyo le-HD 7970 line-platform entsha ngokuphelele ukusetshenziswa kwayo yonke ubuchwepheshe besimanje, ngenxa yokuthi idlula wonke amadivaysi anikezwa ngumncintiswaneni nge-niche yamanani afanayo (ama-ruble angu-15-20 ayizinkulungwane).

Iqiniso lokuthi umphumela kuyisidingo sokudlala elihloniphekile ngentengo engabizi, ungahlulela ngobuningi bamadivayisi akhiwe kule chipset. Bonke abakhiqizi be-video amakhadi abathintekile bathathe le nkinga ngesisekelo se-AMD Radeon HD 7970. Emakethe, umthengi angathola ngisho nokuguqulwa okumbalwa kusuka kumenzi oyedwa - lokhu kuyisibonakaliso esifanele kubasebenzisi abaningi.

Emaphaketheni yangempela

Intengo engabizi emakethe yekhadi levidiyo inikezwa yidivaysi ene-28 nm ubuchwepheshe obunjiniyela be-GCN, enomgomo owodwa kuphela wesithombe (wonke amadivaysi okugcina aphezulu). Ngenxa yobuchwepheshe besimanje, umenzi wakwazi ukufaka cishe ama-transitors angu-4.3 wezigidi ku-HD 7970 chip.

I-core core isebenze ngokuphindaphindiwe kuka-925 MHz, kodwa njengoba abanikazi ekubuyekezeni kwabo bathi, lokhu kuyinani elincane elikhuphuka kalula, lizokufanele ukupholisa. Amabhuloki angu-128 emibhalo kanye nama-ROP angu-32 afakiwe. Inkumbulo isebenza ngo-1375 MHz (esebenzayo engu-5500), inekhono lama-gigabytes angu-3 futhi ixhumana nekhompyutha kumabhasi angu-384-bit. Ngendlela, ibhodi linomshini wokufaka amamojuli amemori engeziwe, ngakho lindela imikhiqizo emisha kusuka kubakhiqizi abane-gigabytes ayisithupha ebhodini (mhlawumbe ngebhasi le-512-bit).

I-adapter ye-high performance video ibangele ukwanda kwamandla ukusetshenziswa - ama-watts angu-250 ngomthwalo ophezulu kakhulu afana nemikhiqizo yomqhudelwano uNvidia. Kuyinto engavamile ukubona imikhiqizo ye-AMD ngezicelo ezinamandla ezinamandla (ngaphambi kokulinganiselwa kufikele ku-130 W).

Inguqulo exaggerated

Ukulandela imikhuba yezimakethe ze-adapter yevidiyo, umenzi wakhe wanquma ukwakha ukuguqulwa okuthuthukisiwe kwedivayisi yakhe kubasebenzisi abafuna ukufuna (uNvidia useyisebenzise isikhathi eside ngaleyo ndlela ngokudala ukuguqulwa kwe "Ti"). Ikhadi levidiyo le-HD 7970 GHz lithengiswa ngesimo esinqunyiwe: i-gray core isebenza ngevolumu ye-1050 MHz, futhi imemori yevidiyo ine-1500 MHz (6000 MHz). Kufanele kuqaphele ukuthi umkhiqizi akenzanga izinguquko ezengeziwe: ukukhushulwa okulindelekile kumkhawulokudonsa ngaphezu kwama-bits angu-384 futhi ukwanda komthamo wememori kuya kuma-gigabytes ayisithupha akuzange kwenzeke. Intengo kuphela eyanda. Njengoba izazi ziphawula ekubuyekezweni kwazo, ukuthenga kuzocaca ukuthi kungenangqondo, ngoba kwimikhiqizo yomqhudelwano, isiqalo esithi "Ti" sinikezwa ngokukhethekile kumadivayisi anomkhawulokudonsa webhodi lememori.

Ukubukeka nokupholisa

Noma kunjalo, sekufikile isikhathi lapho ukufakwa kwedivaysi yokudlala i-AMD idinga icala elihle lezinga le-Tower ATX. Ngempela, ubude be-adaptha buyizingamamitha angu-38, futhi kuthatha izintambo ezimbili ohlelweni lwesistimu, ngokucacile kuthiwa okwesithathu kube nokudla okungcono kwemoya yokupholisa. Izingxenye zebhodi lesifunda eliphrintiwe zifakwa ngokucubungula: i-memps chips ifakwe emhlabeni jikelele wegraphic graphics, futhi izakhi zamandla azange zihlakaze nxazonke zedivayisi, kodwa zithengiswa kahle zibe yunithi eyodwa.

Ikhadi levidiyo elisuselwa ku-AMD Radeon HD 7970 chip linesistimu yokupholisa okuhle. Ingxenye ye-aluminium ye-radiator iyingxenye ebalulekile futhi ihlanganisa amabilidi amabili ebhodini lesifunda eliphrintiwe, isisekelo salo senziwe ngethusi, esinikeza ukushisa okungcono kwezinto ezifudumele. Ekugcineni komsila we-adaptha yevidiyo kufakwe i-turbofan yokuthengisa. Uhlelo lonke lokupholisa luvalwe ngokuqinile nge-casing evikelayo, engavumeli umoya ovuthayo ukuba ubuyele emzimbeni wedivayisi, kodwa uholwa ngaphandle kwegridi yebhokisi elikhulayo.

Isixazululo esingabizi

Ikhadi le-graphics eliphansi kunazo zonke emakethe yaseRussia, i-HD 7970, okubuyekezwa kwayo okuhle kuphela, imelelwe yi-ASUS brand eyaziwa ngokuthi i-ASUS. Ngokokuqala ngqa eminyakeni yamuva, umenzi akazange afake isimiso sakhe sokupholisa, ethemba umenzi. Ngokuvamile, inkampani i-ASUS imangaze kakhulu abalandeli bayo ngokunikeza idivayisi ngesikhwama esifanelekayo: zonke izinhlobo ze-adapters zabaqaphi, i-splitter yamandla, iBridgeFireX bridge yokuxhuma amakhadi amavidyo amaningana.

Ngaphandle, i-adapter yevidiyo ye-ASUS ihluke kumkhiqizo wokuqala we-AMD kuphela ngokubhalwe kwi-hoodator, ngakho-ke ukunakwa komsebenzisi kugxile kuzici zobuchwepheshe zedivayisi. I-ASUS GPU Tweak yombuso ohlinzekiwe ubeke yonke into esikhundleni sayo: ukugqithisa okukhulu kakhulu, okubonisa ukusebenza okuphezulu kwe-adapter yevidiyo, yiyona inzuzo enkulu yomkhiqizi. I-gray core iveza ukusebenza okuzinzile ku-1200 MHz, futhi imodemu yekumemori ayishintshi kumvuthwandaba we-1635 MHz (6500 MHz).

Ukushiswa kwe-icy

I-adapter yevidiyo i-Radeon HD 7970 evela ku-HIS, njengenjwayelo, idonsela amakhasimende kwimikhiqizo yayo ngokubonakala okukhethekile kanye nesistimu yokupholisa ehloniphekile. Ukumemezela izinga lomsindo womkhiqizi we-15 dB akucaci ukunyakaza kokumaketha, ngoba ubuchwepheshe benkampani buguqule ngokuphelele uhlelo lokunikezwa kwamandla kwekhadi levidiyo ngokufaka umlawuli we-PWM wokukhiqiza kwakho nokwandisa inani lezigaba.

I-radiator ye-aluminium ihlanganisa yonke indawo ebhodini lesifunda ephrintiwe futhi ihlatshwa ngamatayipi wezethusi, okuholela ekubambeni okuhambisana nombono wesithombe. Ngaphezulu kukhona ikhava yokuzivikela yensimbi enebalandeli ababili abakhulu, nge-rpm ephansi kakhulu ekwakheni ukuphuma kwamandla emoyeni okungasusa ngokushesha ukushisa kusuka ezintweni zokushisa.

Kuyinguqulo yefektri, imvamisa ye-HD 7970 core ingu-1050 MHz, futhi inkumbulo isebenze ku-1400 MHz, noma kunjalo, njengoba abasebenzisi bephawula ekubuyekezweni kwabo, lezi zibalo azifani nanye uma kuqhathaniswa namandla angaphezu kweqile: 1125 MHz yomsindo kanye no-1575 MHz ngenkumbulo inikeza ukusebenza okuhle kakhulu Emidlalweni.

Imodeli evamile yomkhiqizi owaziwayo

Kodwa inkampani uSapphire idumaze abalandeli bayo, ngoba umkhiqizi wamane wathatha umkhiqizo we-AMD HD 7970 futhi wanamathisela isitika ku-casing yedivayisi. Ngokwemvelo, akukho ukushintshwa okwenziwe okwenzelwe i-PCB. Idivaysi idonsela amehlo emakethe kuphela ngentengo yayo (ama-ruble angu-15 000), angakwazi ukukhokhela abalandeli abaningi bemidlalo enamandla.

I-overclocking ejwayelekile ye-core kuze kufike ku-1200 MHz ayisimangazi noma ubani, kodwa inkumbulo ibonisa ukuzinza ngo-1785 MHz (ephumelelayo engu-7140 MHz). Izinkomba ezinhle kakhulu ezenzweni zokuhlola kanye nemidlalo zihlanganiswa nokusebenza kwesistimu yokupholisa. Ngokusobala, ukushisa okunamandla kwe-core kanye ne-memory chips kubangela ukuthi i-turbofan isebenze ngamandla amakhulu.

Ukulungiswa okuphuthumayo

Kubonakala sengathi, lapho beqaphela amaphutha abo, inkampani uSapphire yanquma ukuvuselela ngokuphuthumayo emakethe ye-adapters yevidiyo. Abathengisi babelethe imikhiqizo emibili ngesikhathi esisodwa: amakhadi wevidiyo e-Radeon HD 7970 Vapor-X kanye ne-Toxic Edition, athengiswa ngezigaba ezimbili ngamunye: nge-gigabytes amathathu ye-RAM ebhodini. Kunomunye udaba - kubonakala ngokushesha ukuthi abathengi bangumkhiqizo obalulekile.

Isistimu yonke yamandla igxile ekuguqulweni: izigaba ezingu-8 + 2 zifakiwe, ezinciphisa kakhulu ukusetshenziswa kwamandla we-adapter yevidiyo. Kufanele kuqaphele ukuthi lo menzi ufake izilawuli zamandla ezizimele futhi washintsha wonke amandla ebhodi elijikelezayo wesifundazwe kuya emotweni okusebenza ngokuqinile. I-Copper ekukhiqizeni ayizange izisole: isisekelo se-radiator, izingxenye namapayipi wokususwa kokushisa kwenziwa ngale nsimbi enhle.

Ukupholisa okunempilo kuyisihluthulelo sokuphumelela kwanoma yikuphi ukuchofoza ngaphezulu. Ingqikithi yegrafu ibonisa ukusebenza okuqinile emvamisa ye-1250 MHz, futhi inkumbulo isebenza kahle ngo-1600 MHz. Ikhono lokuqhubekela phambili ngokweqile, kodwa ngokushesha kunomsindo emsebenzini wabalandeli ababili abancane.

I-monster ephilile

Inkampani ye-PowerColor iziphatha ngokungaqondakali emakethe ye-adapter yevidiyo. Olunye uchungechunge lwamadivaysi athengisa ekukhiqizeni kwefektri, enye - enganaki ngokujwayelekile, kanye nezindleko zesithathu ezinamandla. I-HD 7970, incazelo etholakala ngokoqobo kubo bonke omagazini bekhompuyutha, ifanelwe ukunakwa okukhethekile kumakhasimende, ngoba sikhuluma ngokupholisa amanzi. Ngokushesha kufanele kuqaphele ukuthi ibhulogi yamanzi aliyona mahhala, futhi ngenxa yedivayisi ekuqoqweni, umthengi kuzodingeka akhokhe cishe ama-ruble angu-25 000 (cishe okufanayo yi-flagship ku-chip ye-AMD).

Njengoba izazi ziphawula ekubuyekezweni kwazo, uhlelo lokupholisa amanzi olunikezwa ngekhadi levidiyo lifana kakhulu nebhokisi lwamanzi lomkhiqizo owaziwa yiZalman, futhi isimiso sokusebenza sifana. Ngakho-ke, akufanele kube khona imibuzo ekusebenzeni kahle kwehlelo, njengenhlangano yeyunithi yokupholisa. Kukhona incwadi yokufundisa, iqoqo lezesekeli ngisho nangokhiye.

Ngokwemvelo, i-monster enjalo izonqotshwa kalula ngokweqile, ngoba ukusebenza kahle kokuphefumula kwamanzi kuphakeme kakhulu kune-air blasting. I-core core isebenze kahle ngo-1290 MHz, futhi imemori yevidiyo ihlangabezana nevama ye-1750 MHz (7,000 esebenzayo).

Impembelelo kabili

Abalandeli abajabulayo kanye ne-XFX yenkampani, bathengise imakethe ngokushesha izinguqulo ezimbili ze-chipset HD 7970. Ukubheka kwedivaysi engabizi akufanele kuqale ngisho, ngoba ngemuva kokuthatha ikhadi lesikhamera lesikhamphani, umenzi wenza umdwebo oqoshwayo ekwakheni idivayisi futhi waletha umkhiqizo emakethe. Intengo ephansi ngaphandle kokuthuthukiswa - ayibonakali njengophawu olunzulu.

Kodwa idivaysi yesibili i-XFX izothakazelisa ukudlula ngaphezulu, ngoba umkhiqizi uye wavuma ukuba asuse ngokuphelele uhlelo lokunikezwa kwamandla ebhodini lesifunda eliphrintiwe le-adapter yevidiyo. Abalawuli abanezigatshana zeyunithi yokulawula isigaba samandla, ama-microchips wokukhiqiza kwawo kanye nezinye izinguquko eziningi kuncishise kakhulu ukusebenzisa amandla kwekhadi levidiyo. Ngesistimu yokupholisa, ibhayisikili elisha alizange livuselelwe ngokufaka idivayisi ngomoya opholile, obeka phezu kwe-speed accelerator R9.

Umphumela wazo zonke izinqubo ezintsha kwakuwumsebenzi osebenzayo we-adapter yevidiyo ngokugqithisa ngokweqile emgodini wegraphic 1200 MHz. Imemori ikhombisa ukuzinza ku-1700 MHz. Ukusebenza kahle kwedivaysi okushisa okugcinwe ngaphakathi kwe-degrees Celsius engama-70.

Emncintiswaneni wokusebenza

Inkampani ye-MSI yathumela umkhiqizo wayo ngaphansi kwegama HD 7970 Lightning. Isici esiyinhloko salesi khadi levidiyo yisistimu yokupholisa. Umkhiqizi akazange ahlanganyele ekuthuthukiseni ibhodi lesifunda ephrintiwe, ethembele ngokuphelele ubuchwepheshe be-AMD, kodwa wasebenzisa isikhathi sakhe sonke ekudaleni uhlelo lokususa izinga lokushisa.

Isisekelo se-aluminium sihlanganisa i-PCB ezivela zombili izinhlangothi - isisombululo siyinto engavamile, ngoba azikho izakhi zamandla ngemuva kwedivayisi. Kuwo wonke umjikelezo wekhadi levidiyo i-radiator i-radiator enezibhamu zethusi, eziphelela phansi kumuntu oxhumana naye we-core core. Ezindaweni lapho abalandeli befakiwe khona, ukukhwabanisa kwe-aluminium kunqunywe ukuphakama, kudala izimbobo ezincane zokukhuphula ama-cooler (okukhunjulwa kwe-Gainward Phantom). Ngenxa yokweqa ngokweqile, ungafinyelela ukuzinza kwe-chip ihluzo kumvamisa we-1190 MHz, nomemori - 1650 MHz.

Ekuphethweni

Emakethe yaseRussia kunemikhiqizo eminingi eyenziwe nge-HD 7970 core, kodwa ukusebenza kwabo ngokweqile kuncane kakhulu kangangokuthi kungenzi lutho ukudweba isithunzi sabo. Ukubuyekezwa kubonisa amadivayisi azoba nesithakazelo kubathengi abakhelwe ekuthengeni noma ngezindleko eziphansi, noma ngokukhululeka okukhulu kwekhadi levidiyo. Inkulumo yegolide isanda kuphuma emfashini.
