Radeon HD 7870: ukujongisiswa kwakhona ikhadi levidiyo

Radeon HD 7870 - ikhadi yemizobo abakumgangatho ophakathi, owayebonakele ezishelfini ngo-2012. Yena akazange akwazi Zizigqithile betye zibiza kakhulu, kodwa kakhulu outperforms onobuhle zangaphambili. Umdlalo for AMD Radeon HD 7870 yaba GTX GeForce 570. Le namafutha kwakhululwa iinyanga eziliqela emva HD 7970, nto leyo kumangaliswa abalandeli yenkampani. Nova wayemiselwe ukufumana uhlelo entsha - Southern Islands. Apha waba ngomnye ngabamelii imifuziselo ezimbini ezikhoyo kunye ukusebenza kakuhle kunye nenkqubo olupholisa endilisekileyo. Ukongeza, AMD Radeon HD 7870, ixabiso waba $ 350, ufumene bokwakha ehlaziyiweyo.

izixhobo Packaging

Ikhadi uyangena ibhokisi encinane eyenziwe ikhadibhodi ecwebezelayo. Kwicala ngaphambili umsebenzisi sihlangana uhlobo kakubi Umkhweli wehashe nomsindo ngakumbi. Apha ungabona igama imodeli kunye ngongoma siza kusimangalise HD Radeon 7870.

Ingcaciso engaphezulu kwicala umva. Apha, umsebenzisi sinokufunda iimpawu ezingundoqo namafutha. Ibhokisi ushiya bahle, kodwa inyathelo ukugqibezela.

Ukongeza yevidiyo, lo mqulu olu xwebhu:

• iseti iincwadi;
• CD-ROM ne abaqhubi;
• isethi amaqhoshana;
• PCI-E intambo;
• Crossfire kwebhulorho.

Ngokubanzi, izixhobo Radeon HD 7870 ayikho ngcono okanye ngaphezu koko ezenziwa ngamanye abenzi. Kuba umsebenzi oqhelekileyo akukho mfuneko yokuphinda-kuthenga zabo, ukuba umntu wonwabile. amaqhoshana eyongezelelweyo kusenokufuneka kuphela kwabanye abasebenzisi. Abanye ukuba babe ngokwaneleyo esinika ATI.

ukubonakala

Ngoko nangoko kwatsala ingqalelo lwenjongano ezininzi ukudibanisa nasiphi na isixhobo ngokulula. Iziqalelo ziphambili soldered ukuba kwibhodi yesekethe eshicilelwe emnyama. Ubuso GPU ibonakala ngokucacileyo. Hi ndlela leyi, ikhadi unako ukusebenza ngokubambisana. Nangona kunjalo, lo ibhayisekili ingaba ziingxaki anazo umphakathi ezimbini kuphela imizobo. Ngoko ke, lo nabadlala akayi ukudala "isilo", nto leyo eza kunika ngaphandle izakhelo million enye ngomzuzwana izilungiselelo imizobo ubuninzi.

Ukongeza, ibhodi zihlelwe iimodyuli inkumbulo kunye nemingxuma ezininzi ukuyinyusa inkqubo omkhulu olupholisa. Enyanisweni, imbonakalo ikhadi unako ukwenza into ngaphandle ukuba lo mfundi wokuqala ubona isixhobo efanayo. Bayiphumeza bonke kwizinga pretty ophezulu kwaye ngokuqhelekileyo kwezi amakhadi imizobo.

iimpawu

Ngokusekelwe ikhadi yemizobo kwi engundoqo yemizobo Radeon HD 7870. Usekela iDirectX 11.1, yaye i OpenGL 4.2, ukuba sele wongeza nethemba. Kuye Ndizuze umkhosi lobuchwepheshe ezizizo, ezifana CrossFireX. Nabo, umsebenzisi uya kuba nako ukufumana ukusebenza namafutha kwi ngokupheleleyo. Le ongundoqo basebenzisa rhoqo iwotshi ka 1100 MHz e. Ukudlulisela idata isebenzisa esitsha bit-256 ibhasi.

Video memory iminqongo ziqulunqwe Hynix. Namafutha ine-2 GB of inkumbulo, nto leyo uhlobo GDDR5. Imemori inegumbi rhoqo esebenzayo 5000 MHz e. Oku kwanele ngokuba imidlalo oluninzi lwangoku yonyaka. Noko ke, asingabo bonke onokuyi sebenzisa kwi Useto imizobo ubuninzi.

Le ikhadi levidiyo ekwaziyo ukubonisa umfanekiso neSigqibo ubuninzi 4096x2160 pixels. Namhlanje iimpawu ushiye kangako, kodwa lwabiwo eliphantsi Radeon HD 7870 iya kuba ukhetho ebalaseleyo lokuthenga. Ngokubambisana umqhubekekisi elungileyo, ukuba kunjalo uyakwazi ukusebenza ebalulekileyo befuna iinkqubo.

Isixokelelwano sokupholisa kunye nokusetyenziswa kwamandla i

inkqubo esetyenziselwa Ukupholisa ezimbini-slot. Ngenxa iimpawu umndilili umenzi zange download namafutha kwiindawo zokubeka ezintathu, ezisetyenziswa ngokuqhelekileyo ngendlela imifuziselo enamandla ngakumbi namaxabiso.

Ezibandayo sisixokelelwano enkulu kangangoko, nto leyo eye ventilators ezimbini. Kuba ikhadi levidiyo, le "ayisosakhiwo" ukuba iibholiti-4 kuphela apha. Ngaphakathi kukho imibhobho ezintathu ubushushu ezijongene ngqo isiciko ubushushu-ekusasazeni. Kukho kwakhona sifakele kwiradiyetha encinane aluminiyam. Njengoko sele kukhankanyiwe, okuhlaba fan siyahlangabezana ezimbini ezincinane kwimigaqo azikho kuzo data ekhoyo.

Xa ikhadi mode bengasebenzi lutyabula 32 W amandla. OQhelekileyo oSetyenziswa ukunyuka kakhulu eqalweni ngenkani okanye imidlalo. Umzekelo Crysis 2 (graphics ubuninzi kunye FullHD-isisombululo setting) ukusetyenziswa kwamandla sabhalwa kummandla we-140 W.

ikhadi levidiyo isebenza pretty cwaka. Kwimo bengasebenzi ezibandayo yi isandi phantse inaudible. Nangona kunjalo, phantsi komthwalo kuyanda izinga lengxolo kakhulu, Radeon HD 7870 kule imo kune imifuziselo qinile.
