AMD Radeon HD 6800 Series: uvavanyo kunye kwabalinganiswa

AMD Radeon HD 6800 Series - uthotho amakhadi yoo-ekungabalwa ezaziwayo-kakuhle, AMD. La makhadi imizobo ithabatha indawo thotho kunye index 5. Le ilandelayo ichaza zonke iimpawu yobugcisa, iziphumo zeemvavanyo iiprogram ezizodwa kunye nemidlalo.

History of the ikhadi yemizobo

Kufuneka sicacise ukuba 6800 series lowo wokuqala, leyo yaveliswa phantsi Umfuziselo AMD, njengokuba ATI ayikho semva ngokudibana amabini iinkampani-abenzi lwezincedisi computer.

Ngo-2010, kwafuneka kwakhona ukuhlaziya amakhadi yemizobo umgca eyenziwa yinkampani. Ngexesha intshumayelo AMD kutyhilwa zonke iinkcukacha data zobugcisa nezakhono komdyarho entsha. AMD Radeon HD 6800 Series kuquka imifuziselo ezimbini amakhadi iigrafiki: HD 6850 kunye HD 6870. Ezi amanani amabini okugqibela ukuchaza ikhadi yemizobo yeklasi enemiqathango. Ngako oko ke, engomncinane 6850 no 6870 - endala nenamandla ngakumbi.

Ezi nemizobo badalwa ukubuyisela HD flagship 5870, kodwa, Isimanga, abazange babe ukubakhokela ahlala isikhundla abakumgangatho ophakathi. flagship Le nkampani yaba uthotho kwisalathisi 9 - HD 6900.

AMD Radeon HD 6800: Iimpawu

Ekuphuhlisweni onke amakhadi zangaphambili kwiingcaphephe ATI balandela umgaqo efanayo naleyo olufanayo nabantu ukusuka Nvidia. Oku kuthetha ukuba lonke uphuhliso kunye nemizobo olutsha umlawuli imali neenzame zokufikelela yokusebenza enkulu kunye namandla yentsimbi. Emva kokuba naziphi AMD nkqubo wenkampani nokunxulunyaniswa ukudalwa amakhadi yokuzonwabisa we kuba ezinye kumda wesangqa.

AMD azimisela ukwenza ividiyo kunye ngamandla elungeleleneyo, ukusebenza kunye nexabiso. La manqaku kufuneka akhuphisane GTX 460 kunye GTX 470. Ukuze benze oku, yiko bagqiba ukuphuhlisa GPU entsha. Usahamba mpikiswano malunga nokuba Barts ukwaphula okanye inyathelo ngasemva. Kwelinye icala, ezi bemeko- ziye lula bokwakha nokunciphisa ubukhulu. Kwelinye icala, ukusetyenziswa kwamandla kunye nokusebenza axhome kakhulu xa kuthelekiswa sangaphambili kwekhadi nemizobo evela AMD.

Ngokutsho inkampani, abazange ukwenza nayiphi revolution okanye ukuyila. chip ngemizobo Barts yi ekuphindwa kuyo sizukulwana edlulileyo, kodwa indlela ezintsha nobuchwepheshe ezindala. Esinye sezizathu zale isigqibo ingxaki kunye nemveliso kunye mveliso ngexesha le HD Radeon 6800 AMD kaThixo Series, ngoko ke abasunguli baye bagqiba ukuba liphucule badala.

Kodwa injongo kwaziswa amakhadi kwicandelo ekupheleni-hi mifanekiso isekelwe phezu Ukuphuculwa lwazi bolwakhiwo lwempahla sangaphambili khange kufikelelwe. Le entsha uphulukana nalo ukusebenza HD 5870, kodwa ngaphambi kwayo.

Le series yonke isekelwe Barts iprosesa, ixhasa shaders uguqulelo 5, isixa esiqingqiweyo se yevidiyo memory - 1024 MB. ikhadi nganye ezimbini izihlanganisi DVI, iinkalo ezimbini kunye miniDP enye uqhagamshelwano lwetshiphu emsebenzi. Zombini ezi zixhobo kufuneka inkxaso crossfire kunye yokubonisa ubugcisa nge-8 esweni ngaxeshanye. Abancinci 6850 card yemizobo clocked kwi 775Mgts, abakhulu, 6870, - 900 MHz. Iindleko amakhadi yokuzonwabisa - 180 kwaye $ 240 ngokulandelelana. Kwakhona ikwaxhasa DirectX11, ukuba ngexesha HD Radeon 6800 Series AMD ri nchumu wa nkoka.

amakhadi test

Zombini ikhadi levidiyo series 6800 avavanywe kweemeko ezifanayo kwi kuqwalaselo kwibhentshi efanayo. Zonke iimvavanyo ziqhutywa 3D Mark nemidlalo PC elafikayo ngexesha yokukhululwa ikhadi levidiyo series.

AMD Radeon HD6850

Le umgca imodeli songqamano kolu thotho AMD Radeon HD 6800. Iinkcukacha iphele kakhulu xa kuthelekiswa ne imizobo abadala. Kwaye kuhlukumeza phantsi yonke into, kuquka ukukwazi kwenkqubo sokupholisa. Kodwa abasunguli akukho aye aqwalaselwa elinye: nangona amandla ebuthathaka ikhadi itshiswe ngendlela efanayo. Oku a thabatha ecacileyo.

Ngokutsho iziphumo kwi-3D Mark, le ikhadi levidiyo ungaphantsi thotho abadala kuphela 2-3 amawaka amanqaku. Thatha kakhulu nemveliso yaye befuna imidlalo ngaloo minyaka - Crysis kunye Far Cry 2. Lo mahluko FPS iphakathi-10 no-15 ngesekhondi. Ukuba uthelekisa lo umahluko umahluko ixabiso, ukuthengwa HD 6850 kubonakala isisombululo impela.

AMD Radeon HD6870

Umfuziselo series omdala uphulukana nalo kwentsebenzo flagship HD5870 yenkampani. Wabalasela kukuba ikhadi kwimizobo AMD Radeon HD 6800 Series, ixabiso apho usezantsi kakhulu iindleko sikhuphisana evela kwinkampani Nvidia, evumela ukusetyenziswa onke amathuba DirectX11. Ingakumbi kakuhle umngeni ukumelana njengokuba ixesha HD 6870.

Ukulungiswa Barts iprosesa yemizobo avumele ukufikelela ukhuphiswano kunye flagship AMD inkampani ngokwayo kunye GTX 460 ukusuka kwimemori umthamo Nvidia-1 GB.

UPawulos

Isizukulwana esitsha AMD Radeon HD 6800 Series, ezafumana ncomo engumxube, ngokuqinisekileyo ingqalelo ezixabisa kunye imali yabo. Zombini amakhadi ziye zenzeka phakathi imifuziselo mali kunye HD flagship 5870, kodwa ngaxeshanye, umgca ungakhuphisana sikhuphisana xa icandelo layo lenkampani Nvidia. Iisampulu evela AMD ukhangela kuluncedo kakhulu ngakumbi. Ukwandisa imveliso amakhadi evela Nvidia kuba ncinci, kodwa iindleko ingaphezulu kwi $ 30-40.

Bobubi ezicacileyo ziquka injini nengxolo nge kupholile. Kwiinzame ukugcina lula nakubugcisa, yiko ndilibele ukuba anyamekele lungapholi efanelekileyo. kupholile enomsindo, leyo nzima ukumelana umthwalo, ibetha wonke umnqweno kunokwenzeka ukuba usebenzise ividiyo ubunakho ngokupheleleyo. Kodwa oku kuyimfuneko, kuba kwi-eksperimenti kwaye kukho yemizobo lunikezelo evela Nvidia.
