Radeon HD 7870: ukubuyekeza ekhadini isiqophi

Radeon HD 7870 - ihluzo ikhadi zabantu abasesigabeni esiphakathi zaziba, eyabonakala emashalofini ku 2012. Wayengeyena ukwazi adlula nozakwabo ezibizayo, kodwa outperforms sina onobuhle odlule. Ukudlalela AMD Radeon HD 7870 kwaba GeForce GTX 570. I namafutha wadedelwa izinyanga eziningana ngemva HD 7970, okuyinto kusimangaze abalandeli abaningi inkampani. Nova wayemiselwe ukuba uthole uhlelo fresh - Wik Islands. Lapha waba omunye abamele onobuhle ababili etholakalayo nokusebenza okuhle futhi ehloniphekile Ukupholisa uhlelo. Ngaphezu kwalokho, e-AMD Radeon HD 7870, inani lase $ 350, lithole isakhiwo olusha.

imishini Okufakiwe

Ikhadi iza ibhokisi elincane leyakhiwe ngemabhokisi ecwebezelayo. Ohlangothini front umsebenzisi sihlangana an hlobo kabi umgibeli wehhashi uthukuthela ngokungaphezulu. Lapha ungakwazi ukubona igama imodeli namaphuzu ayinhloko ezokwenza kusimangaze le Radeon HD 7870.

Olunye ulwazi ohlangothini emuva. Lapha, umsebenzisi bangafunda izici eziyisisekelo namafutha. Ibhokisi ishiya isithombe esihle, kodwa hambisa ukuqedela.

Ngaphezu ividiyo, iphakethe kuhlanganisa:

• iqoqo Iincwajana;
• CD-ROM abashayeli;
• isethi adapters;
• PCI-E ikhebuli yamandla;
• Crossfire ibhuloho.

Ngokuvamile, imishini Radeon HD 7870 akuyona ungcono noma kukubi kakhulu kunalokho ahlinzekwa ezinye abakhiqizi. Ukuze operation evamile akudingekile kabusha ukuthenga izingxenye zabo, ukuthi iyajabula. adapters engeziwe zingaboniswa kuphela kudingeka abanye abasebenzisi. Okunye kunganele enikeza ATI.

ukubukeka

Ngokushesha yabakhanga interface eziningana ukuxhuma iyiphi idivayisi kalula. Izakhi eziyinhloko soldered kuya ephrintiwe wesifunda ibhodi ngombala omnyama. Ubuso GPU iyabonakala ngokucacile. By the way, ikhadi ungasebenza Ngohlelo. Nokho, sivule kungaba kuqukathe ihluzo ezimbili kuphela cores. Ngakho-ke, abadlali ngeke ukudala "silo", okuyinto siphele esigidini ngesekhondi iphezulu izilungiselelo ihluzo.

Ngaphezu kwalokho, ibhodi zihlelwe inkumbulo amamojuli futhi izimbobo obandayo amaningi Ukupholisa okukhulu ohlelweni. Ngomqondo onabile, inkulumo ukubukeka ikhadi uyakwazi kusimangaze ngaphandle ukuthi imfundamakhwela owaqala ubona idivayisi efanayo. It izuzwe zonke izinga kuhle okusezingeni eliphezulu futhi ejwayelekile lezi ihluzo amakhadi.

izici

Isekelwe ihluzo khadi ihluzo core Radeon HD 7870. Usekela IDirectX 11.1, futhi VulaGL 4.2, ukuthi kakade unezela nethemba. It usezuze zaziziningi ubuchwepheshe nokuphathelene, ezifana CrossFireX. Nabo, umsebenzisi uzokwazi ukuthola ukusebenza namafutha at zigcwele. Umnyombo usebenza imvamisa iwashi 1100 MHz. Ukudlulisa idatha usebenzisa kahle entsha 256-bit ibhasi.

inkumbulo Isiqophi modules akhiwa Hynix. Namafutha has 2 GB memory, okuyinto uhlobo GDDR5. Imemori ugijima i imvamisa ngempumelelo 5000 MHz. Lokhu Kwanele for ngisho imidlalo zamanje kunazo zonke onyakeni. Nokho, akubona bonke qalisa esiqalisweni esiphezulu izilungiselelo ihluzo.

Ikhadi isiqophi bekwazi ukubonisa isithombe nge isixazululo esiphezulu 4096x2160 pixels. Namuhla izici ashiye okuningi okufanele oyifunayo, kodwa ngezinye ibhajethi ongaphakeme Radeon HD 7870 kuyoba inketho kakhulu ukuze ithengwe. Ngokuhlanganyela processor ezinhle, namanje angenza izimanga ngokufuna izinhlelo.

I ukupholisa uhlelo nokusetshenziswa kwamandla

Ezisetshenzisiwe ezimbili-slot uhlelo indlu. Uma kucatshangelwa izici isilinganiso nomkhiqizi akazange download namafutha Slots ezintathu, ngokuvamile esetshenziselwa ukwenza ngendlela onobuhle namandla kakhulu futhi kuyabiza.

I cooler uhlelo kahle esikhulu, okuyinto has ventilators ezimbili. Ukuze ikhadi vidiyo, lona "sezigidigidi" unamathele imishudo 4 kuphela. Ngaphakathi kukhona amapayipi ezintathu ukushisa ukuthi ngqo nazo isivalo ukushisa-lisakazeka. Kukhona futhi efakwe a Irediyetha elincane aluminium. Njengoba sekushiwo, okuhlaba fan ahlangane ezimbili ezincane incazelo ye iyiphi idatha azitholakali.

Ngo kokungenzi lutho kumodi ikhadi ibusa 32 W amandla. Ukusetshenziswa inyuka kakhulu ekuqaleni bafuna ukunyuselwa amaholo noma imidlalo. Ngokwesibonelo ngo-Crysis 2 (ihluzo esiphezulu futhi FullHD zokulungiswa kulungiselelwa) amandla ukusetshenziswa lwalotshwa indawo 140 W.

ikhadi Isiqophi isebenza Kuhle. Kwimodi kokungenzi lutho le epholile cishe inaudible umsindo. Nokho, ngaphansi komthwalo ukwanda umsindo ezingeni kakhulu, Radeon HD 7870 kule modi idlula onobuhle ngisho namandla kakhulu.
