AMD Radeon HD 6800 Series: neNgcaciso, inkcazelo kunye neemvavanyo

AMD Radeon HD 6800 Series - uthotho amakhadi yevidiyo, AMD. Umenzi components iikhompyutha imbali ukhuphiswano kunye Nvidia ikhadi yemizobo umenzi. Le ngxelo iqwalasela iingenelo neengozi le Radeon HD 6800 AMD kaThixo Series. Iinkcukacha, iinkcazelo kunye neziphumo zovavanyo - konke oku unako ukufumana ngezantsi.

Ukufika ividiyo ikhadi series

AMD uye rhoqo kubuyekeza komgca iziqhubekisi imizobo kunye namakhadi imizobo. 2010 kwakungekho ngaphandle uluntu uthotho ka 6800. Lo mgca yaqaliswa wadalwa endaweni ikhadi yemizobo flagship 5870.

October 22 ithiwe thaca kwi-ikhadi yemizobo AMD Radeon HD 6800 Series. Otyvy ngayo ngexesha ntetho selayini enentsholongwane kuphela. Ngo-2010, AMD yaphinda yathandwa kuphela kunye namakhadi yemizobo zabo, ukuze bonke bephela babelinde ukuba Breakout technical, okanye ubuncinane flagship series elungileyo kakhulu.

Kungoko kulo mgca luyaphela ngokupheleleyo iimveliso rebranding ukususela ngoku kuse kule mini ikhadi video igama lenkampani AMD, ndingangi ATI. Oku kwenziwa ngenxa ekupheleni kwekhontrakthi emva hlelo. Mhlawumbi lo isigqibo athatyathiweyo ukukhuthaza kuphela chip yemizobo, kodwa iziqhubekisi, AMD. Umqukumbelo oku kuvela ngenxa yopapasho rhoqo ntetho esimo eziqokelelweyo kuphela eqongeni AMD (CPU + GPU).

Bona yintoni amakhadi kwenzé emarikeni ukuze desktops AMD line of Radeon HD 6800 Series, iimpawu zazo ziboniswa apha ngezantsi. Lonke series enikwa amakhadi mifanekiso ilandelayo: HD 6850 no 6870. Ngokutsho abasunguli ngokwabo, inani 8 kwisalathiso nguhayi elide yelo ukuya phezulu chips yemizobo uluhlu, ngenxa yokuba kwakukho uthotho 6900.

AMD Radeon HD 6800 Series: iinkcukacha

Okokuqala, kuyimfuneko ukuthetha malunga notshintsho eqongeni. Umgca entsha iprosesa esetyenziswayo Barts. Ukususela yokuqala, kwaye kwacaca ukuba AMD wakhetha indlela eyahlukileyo yophuhliso ngaphezu Nvidia. Ukuba zokugqibela rhoqo ukufumana amandla kunye nokusebenza ubuninzi, yenzelwe amakhadi yemizobo Radeon ukuba umlinganiselo balance, ngokungathi oko kuvakala corny, ixabiso kunye nomgangatho (yokusebenza).

Iingcali ezivela inkampani yangaphambili ATI udla ngokuba ngcungela lokwenyaniso. Bacela lo mkhuba ukuba lentengiso chips imizobo. Emva inguqu phantsi iphiko, AMD wathabatha inyathelo umva. Isizukulwana esitsha iziqhubekisi Barts nokuba buthathaka lokugqibela iphepha ekusebenzeni. Koqobo engaphambili lula lwezakhiwo ukufikelela ukulinganisela phakathi isantya, ukuthembeka kunye nemveliso. Barts iye yaba lula kubume kunye ezincinane ubukhulu. Le wegama sisiseko abakumgangatho ophakathi kunye namakhadi ephantsi, nto leyo ekhathaza HD Radeon 6800 AMD kaThixo Series. Ezi mpawu ziye thaca ngezantsi.

Zombini abameli thotho (HD 6850 no 6870) lixhasa DirectX11 kunye Shader Version 5. Iindleko amakhadi yi-180 kunye $ 240 ngokulandelelana. Kuthelekiswa ne ukusebenza kunye overclocked ke okhuphisana ukusuka Nvidia motherboard evela AMD indleko ephantsi ngokwenene, kodwa umahluko yokusebenza ayikho mkhulu kangaka. Video memory omabini amakhadi - 1GB. A manqaku eyimbangi GeForce GTX460 ngqo nge-1 GB RAM kunye GeForce GTX470.

AMD ikhadi yemizobo Radeon HD 6800 Series: iimpawu kunye neziphumo zeemvavanyo

Ukuvavanya ikhadi ividiyo kwakusetyenziswa le layini ilandelayo yoqwalaselo ye computer njenge testbed: Core i7 iprosesa kunye rhoqo 3.3 GHz, 6 GB of RAM kunye bit-64 yokusebenza Windows 7. Yonke imidlalo zibekiwe ukuba basebenzise umgangatho yemizobo kunye neenkcukacha ukuqinisekisa eliphezulu amakhadi test yokusebenza.

Umdlalo wokuqala yaba uvavanyo Aliens vs. Mbulali. Xa kucaca ukuba olu luhlu HD6800 kuya kuba nzima ukuba akhuphisane i GeForce 460 1GB: kuphela ngokulungiswa 1600x900 kunye nentlawulo ephantsi ukusuka AMD unokuhlangula ayidlaleki izakhelo 30 ngomzuzwana.

Xa Battlefield Bad Company 2 umdlalo, loo meko ebulungelelanisile, kwaye akubonakali ukuba isigqibo embi kangaka ekufunyanweni AMD Radeon HD 6800 Series. Ukubalula kwi kwimizobo evumela isicwangciso iphezulu (6850 no 6870) kwenza kube lula ukuba Kwathi GeForce yonke 8 izakhelo yesibini (30 to 22) nganye. Khumbula ukuba Nvidia ikhadi yemizobo ixabiso yi-230 zeerandi. Uluhlu omtsha AMD beqhubeka babe nomtsalane. Kodwa ke ngaphandle kokwenza naziphi na izigqibo ezingacingwanga, khangela iimvavanyo zilandelayo.

Xa umdlalo onzima kakhulu Crysis Warhead zigcinwa omabini amakhadi ngokwaneleyo kuphela kwi resolution ezisezantsi kwikhusi. Ikuba Call of Pripyat unika abaphambili ikhadi yemizobo ukusuka Nvidia 10 ngesekhondi. Kodwa musa ukulibala ngomahluko kakhulu ngexabiso.

Isiphelo emva kovavanyo

Ngokubanzi, yonke imidlalo ufanelwe ikhadi ibonisa HD Radeon 6800 AMD kaThixo Series. Umqhubi emva uphuculo waqala ukuxhasa zonke imidlalo ezintsha, ngoko inguqulelo mali chip yemizobo ukusuka AMD ivelise Unyamezele 25-30 ngesekhondi kwiiprojekthi umdlalo mihla izilungiselelo eliphezulu imizobo.

AMD Radeon HD 6800 Series: nobubi

Ezi zinto zilandelayo kuhlawuliswa iingenelo eli khadi. Okokuqala, lo intsebenzo entle ezininzi imidlalo mihla. , Ukusetyenziswa yesibini amandla aphantsi. Unga kwakhona uqaphele indleko ephantsi, apho umthengi ukufumana zentsebenzo kunye namakhadi "chips" zonke yemizobo isiphelo top-, ezifana imveliso liso 6, imo ehambelanayo , kunye nekhadi yemizobo efanayo.

Ilishwa nizimele ekwandeni ingxolo injini card mifanekiso ngokuphandle buthathaka. Xa imithwalo ngokwaneleyo ephezulu kwiqhezu yevidiyo iqalisa shushu ngokugqithisileyo ngokukhawuleza.

ngenxa

Kuba abo na sizama ngamandla intuthuko kanye amanani aphezulu kwezi mvavanyo, umgca ogqibeleleyo AMD Radeon HD 6800 Series. amakhadi Iimpawu ukuvumela lidlala ngokukhuselekileyo FPS omkhulu aphakathi okanye kufutshane nokucwangcisa icandelo yemizobo yomdlalo. Kwicala amakhadi iigrafiki AMD kwakhona iindleko ephantsi, xa kuthelekiswa Nvidia GeForce 460 no 470. Noko ke, ukusebenza yahlukile kancinane, ngoko ke ukhetho amakhadi yemizobo isiphelo ephantsi-avareji izicacele.
