Daim video

Yees duab nco yog ib yam tseem ceeb tshaj plaws ntawm daim video. Nws muaj cwj pwm zoo heev ntawm tag nrho cov kev ua tau zoo, qhov zoo ntawm cov duab tso tawm, nws txoj kev daws teeb meem, thiab tsuas yog ntawm kev siv ntawm daim video, uas koj yuav kawm txog los ntawm kev nyeem ntawv no. Nyeem kuj: Cov teebmeem ntawm kev ua si hauv xovtooj (RAM) Lub koob yees duab tshwj xeeb hauv kev sib tham video yog hu ua video nco thiab hauv nws cov ntawv sau ntxiv rau DDR (muab ob npaug rau ntaub ntawv) muaj daim ntawv G thaum pib.

Txoj kev loj hlob thiab kev tsim ntawm thawj qauv qauv ntawm cov ntawv teev lus video yog paub txog ntau lub tuam txhab AMD thiab NVIDIA, tab sis tsuas yog ib feem me ntawm cov duab accelerators ntawm cov tuam ntxhab no nkag mus rau hauv lub khw. Feem ntau, cov tuam txhab sib koom nrog, uas hloov cov tsos thiab qee cov ntsiab lus ntawm cov ntawv teev lus thaum lawv pom zoo, nkag mus rau hauv haujlwm.

Thaum siv daim vev xaib, peb yuav ntsib ntau qhov teeb meem thiab kev ua haujlwm, ib qho ntawm qhov tsis yog ib qho cuab yeej hauv Windows Manager Device. Feem ntau, xws li kev ploj zuj zus raug pom thaum muaj ob qho kev hloov khoom nruab nrog hauv qhov system - kev sib txuas thiab kev sib faib. Tsuas yog lub xeem thiab tuaj yeem "ploj" ntawm daim ntawv teev cov khoom siv tau.

Hauv lub ntiaj teb niaj hnub no, coob leej tau hnov ​​txog lub tswvyim ua video card. Cov neeg tsis paub txog tej zaum yuav xav tias nws yog dab tsi thiab vim li cas koj xav tau ntaus ntawv no. Ib tug neeg yuav tsis xa qhov tseem ceeb rau qhov GPU, tab sis hauv vain. Koj yuav kawm txog qhov tseem ceeb ntawm daim video thiab lub luag haujlwm nws ua nyob rau hauv cov txheej txheem hauv tsab xov xwm no.

Kev txhim kho cov tsav tsheb rau NVIDIA daim npav yog kev yeem thiab tsis tas yuav tsum tau, tab sis nrog tso tawm cov software tshiab, peb tuaj yeem tau txais "cov pob" ntxiv rau daim ntawv zoo dua qhov ua kom zoo dua, muaj kev ua tau zoo hauv qee cov kev ua si thiab kev siv. Tsis tas li ntawd, cov tshiab versions kho ntau yam yuam kev thiab kev ua yuam kev hauv qhov chaws.

Ib daim video card yog ib txoj hlua uas yuav tsum tau ua kom tau siab tshaj plaws nrog nruab hardware thiab software. Qee lub sij hawm cov adapters muaj teeb meem uas ua rau nws tsis yooj yim sua kom siv lawv ntxiv. Nyob rau hauv tsab xov xwm no peb yuav tham txog kev ua yuam kev 43 thiab seb nws tuaj yeem kho tau li cas.

Raws li txoj cai, cov kev tshaj tawm tshiab rau qhov software software rau tus qauv processor coj kev txhim kho nyob rau hauv kev kawm thiab kev txhawb nqa rau kev yees duab tshiab. Qee lub sij hawm, txawm li cas los xij, qhov tshwm sim txawv yog pom: tom qab tus tsav tsheb hloov tshiab, lub computer pib ua haujlwm zuj zus. Cia peb kawm saib yog vim li cas qhov no tshwm sim, thiab yuav kho qhov no li cas.

Ncauj los sis tom qab hauv lub neej ntawm txhua lub computer los txog lub sijhawm ua haujlwm tsis tiav. Qhov no txhais tau hais tias nws tau tsim nyog los hloov cov khoom qub nrog cov tshiab, niaj hnub no. Muaj ntau cov neeg siv kev ntshai ntawm nws tus kheej koom rau hauv qhov kev tsim kho hlau. Nyob rau hauv tsab xov xwm no peb yuav qhia, siv cov piv txwv ntawm disconnecting ib daim video card los ntawm motherboard, tias tsis muaj ib yam dab tsi uas qhov ntawd.

Saib ntawm cov yam ntxwv ntawm cov laptops, koj tuaj yeem pheej thuam tus nqi "kev" hauv kev tshav pob los qhia seb hom video card. Nyob rau hauv tsab xov xwm no peb yuav pom cov duab zoo li cas, nws yog dab tsi, thiab lwm yam teeb meem muaj feem xyuam nrog lub npe ntawm daim duab chaav duab.

Nyob rau hauv kev ua si, daim video ua haujlwm siv ib qho nyiaj ntawm nws cov nyiaj txiag, uas tso cai rau koj kom tau txais cov duab kos tau zoo tshaj plaws thiab nyiam FPS. Txawm li cas los xij, tej zaum cov graphic adapter tsis siv txhua lub hwj chim, vim tias qhov kev ua si pib qeeb thiab smoothness ploj. Peb muab ntau lub ntsiab rau qhov teeb meem no.

Lub laptop niaj hnub, hauv kev sib piv nrog nws cov neeg laus cov neeg laus, yog lub tuam txhab muaj hwj chim zoo heev. Cov khoom tsim tau ntawm cov hluav taws xob hlau yog nce txhua txhua hnub, uas yuav tsum tau muaj zog ntau dua. Yuav kom cov roj teeb muaj zog, manufacturers yuav nruab ob daim video card hauv laptops: ib qho ua rau hauv lub motherboard thiab muaj qis zog siv, thiab qhov thib ob discrete, haib dua.

Thaum nyeem cov ntaub ntawv hais txog cov khoom ntawm cov tshuab computer, koj yuav thuam li qhov khoom ua ib daim video card nrig. Nyob rau hauv tsab xov xwm no peb yuav saib seb daim npav discrete li cas thiab qhov nws muab rau peb. Ntaus ntawm daim npav discrete Ib daim ntawv pov thawj uas tsis tau sib cais yog ib qho khoom siv los ua ib qho khoom sib txuas, uas yog, nws tuaj yeem raug tshem tawm tsis cuam tshuam rau ntawm PC.

Yog tias koj pib pom tias lub suab nrov nrov ntawd ua rau lub computer ua haujlwm nce ntxiv, ces nws yog lub sijhawm los ntub cia txias. Feem ntau ua suab nrov thiab nrov nrov ua rau nws tus kheej tsuas yog thaum thawj feeb ntawm lub kaw lus, tom qab ntawd lub qhov hluav taws xob sov so ntawm qhov kub thiab txias rau hauv cov kabmob, txo kev sib txhuam. Nyob rau hauv tsab xov xwm no peb yuav xyuas cov txheej txheem ntawm lubrication ntawm lub tso rau hauv daim video.

Txij lub sij hawm, koj pib pom tias qhov kub thiab txias ntawm daim card ntawd ntau dua tom qab kev yuav khoom. Lub kiv cua txias txhua zaus tig rov qab rau hauv tag nrho quab yuam, sib tw thiab dai ntawm qhov screen. Qhov no yog overheating. Overheating ntawm ib daim video yuav tsum yog ib qho teeb meem loj. Txo cov dej kub tuaj yeem ua rau muaj qhov teeb meem rov qab thaum lub sijhawm ua haujlwm, nrog rau kev puas tsuaj rau lub cuab yeej.

Ob peb xyoos dhau los, AMD thiab NVIDIA qhia cov tswv yim tshiab rau cov neeg siv. Nyob rau hauv thawj lub tuam txhab, nws yog hu ua Crossfire, thiab nyob rau hauv lub thib ob - SLI. Qhov no feature tso cai rau koj mus txuas ob daim video card rau ntau qhov kev ua tau zoo, uas yog, lawv yuav ua ib qho duab ua ke, thiab hauv txoj kev xav, ua haujlwm ob zaug ceev ceev raws li ib daim npav.

Qee zaum, thaum lub caij nyoog kub high, video phaib yauv siv cov koob yees duab nti lossis cim xeeb chips. Vim li no, muaj ntau yam teeb meem, xws li cov duab ntawm artifacts thiab cov xim liab ntawm lub vijtsam, xaus nrog qhov tsis tiav ntawm daim duab. Txhim kho qhov teeb meem no, nws yog qhov zoo dua yog hu rau qhov chaw pabcuam, tab sis ib yam dab tsi tuaj yeem ua nrog koj tus kheej tes.

Thermal grease (thermal interface) yog ntau yam khoom sib txawv tsim los txhim kho cua sov los ntawm tus ntiv taw mus rau lub tshuab radiator. Cov nyhuv yog tiav los ntawm kev txhim kho cov teeb meem ntawm ob qho tib si, qhov muaj cov cua khoob nrog cov thermal siab thiab, yog li ntawd, cov thermal conductivity tsawg.

Hom kev yees duab nco hauv graphics adapter tsis tsawg kawg yog txiav txim siab txog theem ntawm nws qhov kev ua tau zoo, as Well as tus nqi rau qhov chaw ua lag luam yuav muab tso rau hauv kev ua lag luam. Tom qab koj nyeem cov lus no, koj yuav kawm tau ntau hom video nco tau txawv ntawm ib leeg. Ib qho tseem ceeb tshaj plaws peb yuav los txuas rau lub npe ntawm lub cim xeeb ntawm nws tus kheej thiab nws txoj hauj lwm ntawm kev ua hauj lwm ntawm GPU, thiab tseem ceeb tshaj plaws, peb yuav kawm saib hom kev nco uas tau teev nyob rau hauv daim video card hauv koj lub cev.

TDP (Thermal Design Power), thiab hauv Lavxias tebchaw "cov cua sov", yog ib qho tseem ceeb heev uas yuav tsum tau nco ntsoov thiab ua tib zoo mloog thaum nws xaiv ib qho computer. Feem ntau ntawm tag nrho cov hluav taws xob hauv lub PC yog siv los ntawm lub hauv paus nruab nrab thiab ib nti graphics nti, hauv lwm lo lus, daim video.

Yav tas, video phaib tau txuas nrog lub monitor siv lub VGA video interface. Cov duab hloov tau ua siv cov teeb liab analog tsis muaj suab tso tawm. Cov cuab yeej tsim tau tsim nyob rau hauv xws li ib txoj kev uas VGA-saib yuav ua hauj lwm tsis muaj teeb meem nrog tshiab versions ntawm graphics adapters uas txhawb ntau xim.
