AMD Radeon HD 6800 Series: kev soj ntsuam thiab characterization

AMD Radeon HD 6800 Series - ib tug series ntawm mid-range phaib ntawm zoo-paub, AMD. Cov graphics phaib tau hloov lub series nrog index 5. Cov nram qab no piav qhia txog tag nrho cov kev yam ntxwv, tus kuaj tau nyob rau hauv kev kawm tshwj xeeb thiab kev ua si.

Keeb kwm ntawm lub graphics card

Nws yuav tsum tau clarified tias cov 6800 series yog tus thawj, uas tau tsim nyob rau hauv lub emblem ntawm AMD, raws li ATI yog tsis tau tom qab lub merger ntawm ob tuam txhab uas muag-manufacturers ntawm computer accessories.

Nyob rau hauv 2010, nws tau los ua tsim nyog ib zaug dua los mus hloov cov kab graphics phaib muaj los ntawm lub tuam txhab. Thaum lub sij hawm qhov kev nthuav qhia ntawm AMD qhia tag nrho lub ntsiab lus ntawm cov kev cov ntaub ntawv thiab muaj peev xwm ntawm tus tshiab series. AMD Radeon HD 6800 Series muaj xws li ob qauv ntawm graphics phaib: HD 6850 thiab HD 6870. Lub ob tug lej tom qab txhais tau lub zwj ceeb hauv chav kawm ntawv graphics card. Raws li, nws yog tus yau 6850 thiab 6870 - cov laus thiab ntau haib.

Cov graphics twb tau tsim kom hloov cov flagship HD 5870, tab sis, oddly txaus, lawv twb tsis ua, thiab nyob rau hauv lub txoj hauj lwm ntawm nruab nrab hauv chav kawm ntawv. Lub tuam txhab flagship yog ib tug series ntawm index 9 - HD 6900.

AMD Radeon HD 6800: Nta

Nyob rau hauv txoj kev loj hlob ntawm tag nrho cov yav tas los phaib ntawm ATI kws txawj ua raws li cov ntsiab cai tib yam li hais tias ntawm lawv cov counterparts los ntawm Nvidia. Qhov no txhais tau tias tag nrho cov tshiab uas thiab graphics kav nyiaj ua lag luam rau siab ua raws ntau qhov kev ua thiab lub hwj chim ntawm hlau. Tom qab lub merger nrog AMD lub tuam txhab txoj cai thiab mus kom ze rau lub creation ntawm video phaib peb muaj ib co lwm yam vector.

AMD teem tawm mus ua ib tug yees duab nrog ib tug kuas hwj chim, kev kawm thiab tus nqi. Qhov no series yuav tsum sib tw nrog GTX 460 thiab GTX 470. Ua li no, lub creators txiav txim siab los tsim ib tug tshiab GPU. Tseem taug kev sib cav tswv yim hais txog seb Barts lov los yog ib kauj ruam rov qab. Nyob rau hauv ib tes, lub creators tau yooj yim zog cov architecture thiab txo qhov luaj li cas. Nyob rau lwm cov tes, lub hwj chim noj thiab kev ua tau zoo muaj ntau piv rau lub yav dhau los tiam ntawm graphics phaib ntawm AMD.

Raws li lub tuam txhab, lawv tsis ua tej yam kev kiv puag ncig los yog txhob. Graphic nti Barts yog ib tug repetition ntawm yav dhau los tiam, tab sis nrog ib tug tshiab mus kom ze rau cov laus technologies. Ib tug ntawm cov yog vim li cas rau qhov kev txiav txim yog qhov teeb meem nrog cov ntau lawm thiab lub Hoobkas ntawm lub sij hawm ntawm lub Radeon HD 6800 AMD lub Series, li ntawd, lub creators tau txiav txim siab los txawj tej yam ntxiv cov laus tiam.

Tab sis lub hom phiaj ntawm populating lub ya hi-kawg graphics phaib raws li nyob rau hauv lub Modernization ntawm yav dhau los tiam architectures tsis tau tau tiav. Tus tshiab series ntog luv luv ntawm qhov kev kawm ntawm cov HD 5870, tab sis tsis ua ntej ntawm nws.

Tag nrho series yog raws li nyob rau hauv Barts processor, txhawb shaders version 5, ib taag nqi ntawm video nco - 1024 MB. Txhua daim ntawv muaj ob tug connectors DVI, ob qho thiab ib tug miniDP rau HDMI. Ob leeg li muaj kev txhawb nqa rau crossfire thiab zaub technologies nyob rau hauv 8 saib ib txhij. Yau 6850 graphics card yog clocked ntawm 775Mgts, senior, 6870, - 900 MHz. Tus nqi ntawm cov video phaib - 180 thiab $ 240 feem. Nws kuj txhawb DirectX11, hais tias thaum lub sij hawm ntawm lub Radeon HD 6800 AMD lub Series yog ib qho tseem ceeb.

Test phaib

Ob video card series 6800 tau kuaj nyob rau hauv tib tej yam kev mob nyob rau tib lub rooj ntev zaum configuration. Tag nrho cov kev ntsuam xyuas los xij nyob rau hauv 3D Mark thiab PC ua si uas tuaj thaum lub sij hawm ntawm kev tso tawm ntawm daim video series.

AMD Radeon HD6850

Cov qauv no kab yog lub weakest nyob rau hauv lub series AMD Radeon Hd 6800. Specifications heev curtailed li muab piv nrog cov laus graphics. Thiab nws txiav down txhua yam, nrog rau cov muaj peev xwm ntawm lub txias system. Tab sis lub creators tsis tau xam tau tias yog ib tug: txawm weaker muaj peev xwm card yog rhuab nyob rau hauv tib txoj kev. Qhov no yog ib tug meej rho tawm.

Raws li kev soj ntsuam nyob rau hauv lub 3D Mark, qhov no video card yog ua tsis tau zoo rau cov laus series yog tsuas 2-3 txhiab cov ntsiab lus. Siv lub feem ntau tsim thiab xav tau kev ua si nyob rau hauv cov xyoo - Crysis thiab dhau deb quaj 2. Qhov txawv nyob rau hauv lub FPS yog nruab nrab ntawm 10 thiab 15 ntas ib ob. Yog hais tias peb muab qhov no piv txawv mus rau lub sib txawv nyob rau hauv nqe, tus purchase ntawm HD 6850 zoo txaus nyiam heev tov.

AMD Radeon HD6870

Cov laus cov qauv series ntog luv luv ntawm qhov kev kawm rau hauv lub tuam txhab flagship HD5870. Tshwj xeeb yog noteworthy yog hais tias lub graphics card AMD Radeon HD 6800 Series, tus nqi ntawm uas yog tsawg tshaj tus nqi ntawm cov neeg sib tw los ntawm Nvidia lub tuam txhab, tso cai rau kev siv ntawm tag nrho cov sij hawm rau DirectX11. Tshwj xeeb yog zoo rau cov kev sib tw mus rau tiv li lub sij hawm HD 6870.

Cov txawj tej yam ntxiv ntawm cov Barts graphics processor tau tso cai kom ua tau competitiveness nrog lub flagship AMD lub tuam txhab nws tus kheej thiab GTX 460 los ntawm Nvidia lub cim xeeb muaj peev xwm ntawm 1 GB.

Summing li

Lub cim tshiab ntawm AMD Radeon HD 6800 Series, uas tau txais mixed xyuas, twv yuav raug hu muaj nqis saib xyuas thiab lawv cov nyiaj. Ob leeg phaib muaj npaum li cas qhov chaw ntawm cov nyiaj txiag ua qauv thiab cov flagship HD 5870, tab sis nyob rau tib lub sij hawm, txoj kab yuav lwv nrog cov neeg sib tw nyob rau hauv nws ya ntawm lub tuam txhab Nvidia. Kuaj los ntawm AMD zoo ntau npaum li cas ib qho kev zoo. Ua kom tsim tau ntawm video phaib ntawm Nvidia yog tsawg heev, tab sis tus nqi yog siab dua nyob rau hauv $ 30-40.

Cov cuab disadvantages muaj xws li ua pa nrov txias system nrog ib tug txias. Nyob rau hauv ib qho kev rau siab mus cawm thiab piv cov architecture, lub creators tau tsis nco qab lawm mus saib xyuas kom zoo cua txias. Nrov txias, uas nyuam qhuav tiv nrog lub load, neeg ntaus txhua lub siab xav mus siv video peevxwm los lub hom phiaj zoo. Tab sis qhov no yog tsis tsim nyog, vim hais tias nyob rau hauv lub sim kawm thiab muaj cov graphics acceleration ntawm Nvidia.
