Yuav ua li cas yog lub computer graphics card

Tej zaum, lub web mus nrhiav tau rau lo lus nug "dab tsi yog qhov graphics card." Txawm hais tias nws mas tsis tseem ceeb, txawm li cas los, tus neeg uas txiav txim siab kom to taub nws deserves sib hwm, raws li nrhiav kom to taub cov ntaus ntawv ntawm lub computer.

Sawv daws yeej paub hais tias cov ua hauj lwm ntawm tag nrho cov xam pab kiag li lawm raws li nyob rau hauv lub binary sawv cev ntawm cov ntaub ntawv. Leej twg tau puas tau pom ib tug sib lawv liag ntawm zeros thiab sawv daws yuav muab tau rau ntawm daim ntawv los yog computer screen, yeej paub tias muaj yog mus rau to taub hais tias ib yam dab tsi yog yuav luag tsis yooj yim sua. Qhov no yog yooj yim piav qhia, vim hais tias tag nrho cov nuj nqis - ib yam ntawm cov micro-ops rau transistors. Yuav ua li cas yog tus piv ntawm cov saum toj no, cov lus nug ntawm yog dab tsi ib tug graphics card? Direct! Yuav ua li cas peb pom nyob rau hauv qhov kev tshuaj ntsuam yog ib tug nrog computer cov ntaub ntawv ntws hloov dua siab tshiab rau hauv coj los tib neeg cim. Qhov teeb meem ntawm no transformation yog cia li muab tso rau daim video card.

Cia peb txhais lub tswvyim ntawm "dab tsi yog qhov graphics card." Video adapter (graphics card) - ib tug ntaus ntawv tsim los tso saib graphics rau qhov kev tshuaj ntsuam (zoo ib yam li yuav ua li cas lub tshuab luam ntawv prints rau ntawm daim ntawv). Ntxiv mus, tsis tag nrho cov ntaub ntawv, thiab nyob rau hauv ib txoj kev npaj. Piv txwv li, yog tias koj sim mus tso saib cov kwj ntawm cov hard disk commands ntawm video, ces tsis muaj dab tsi tshwm sim. Tag nrho cov sab hauv cov ntaub ntawv yog pre-npaj los ntawm tus CPU rau txhua lub hom phiaj ntaus ntawv: lawv tshaaj cov yam chaw nyob chaw tos tsheb loj yog qhia thiab li ntawd.

Tiam sis tag nrho cov saum toj no tsuas yog siv rau cov software tivthaiv, yog li ntawd, xav tias yog li ntawd ib mog, peb yuav teb tsis tau rau hauv kom meej rau lo lus nug "dab tsi yog qhov graphics card." Lub cev, nws yog ib qho expansion board uas qub rau hauv ib tug coj ntsawb (qhov) ntawm lub motherboard (mainboard). Ze li ntawm tag nrho cov niaj hnub video adapters yog tsim rau cov PCI Express.

Cov nram qab no Cheebtsam yog on board: ib tug graphics processor, xws li, video card nco (RAM thiab ROM), ib lub tsheb npav connector thiab tso zis connector, DAC, txias system, nrog cov ntsiab. Nyob rau hauv ib co qauv, daim ntawv yuav raug ncua nrog ntxiv Cheebtsam.

video tsis yog lom zem ntau los ntawm tus hloov kho duab processor. Lawv tam sim no lawm deal ob tuam txhab uas muag - AMD (ATI), thiab NVIDIA. Cov qhia tawm ntawm lwm cov me me, Txawm hais tias zoo-paub Intel yog tseem sim hais lawv qhia tawm ntawm lub lag luam.

graphics processor (GPU) tau raug tsim cov duab ntawm cov ntaub ntawv yog muab los ntawm daim ntawv thov. Tus nab npawb ntawm transistors nws tshaj no daim duab nyob rau hauv lub hauv paus processor, uas yog indicative ntawm nws unparalleled kev kawm. Los ntawm txoj kev, qhov no yog vim li cas ntau thiab ntau koj yuav nrhiav tau tshwj xeeb cov kev pab cuam uas tau suav rau hauv lub GPU. Yog, thiab gaming daim ntaub ntawv los ntawm lub caij muab (PhysX, DirectCompute) ntev dhau los kawm tau li cas siv nws cov kev pab rau zauv, uas tsis yog-imaging.

Lub xws yog tasked sis nrog nco li zoo li sab hauv thiab sab nraud tsheb npav. Ntsis ntsis nrog bus - nws yog tus thib ob daim duab tom qab qhov kev kawm GPU tseem ceeb. Tam sim no muab faib ua qauv ntawm 64, 128, 256 los yog ntau tshaj cov khoom. Tau tsawg tshaj li 128 yog tsis pom zoo.

Lub cim xeeb nyob rau hauv cov graphics card yuav tsum tau cia thiab ua cov dluab uas tsim los ntawm lub GPU, nyiaj tso ncaj tso zis rau lub screen. Tsiag ntawv los ntawm hom ntsia chips (DDR - GDDR5) thiab ntim. Qhov ceev tshaj plaws cov ntsiab tuaj nrog GDDR5. Niaj hnub nimno kev ua si yuav tsum tau tsawg kawg yog 512 MB ntawm volume (nyob ntawm chaw).

Txhua daim ntawv yog, raws li twb tau hais, yog tsim los rau ib lub log tsheb. Tam sim no lug siv PCI Express 16. Tej zaum kuj muaj PCI, tab sis ntau dua qhov nqi. Ob peb xyoos dhau los, computers reigned lub AGP tsheb npav, tab sis lub Intel, raws li ib txwm, nyob rau hauv lub sij hawm yuav tsum nws.

O connector txhais ib interface uas koj yuav xa ib lub teeb liab mus rau lub monitor. Ob peb ntawm lawv: outdated D-SUB, cov DVI, niaj hnub HDMI, Muab Chaw nres nkoj, thiab li ntawm.

Tej zaum cov graphics card yog ib feem ntawm lub CPU, nyob rau hauv cov ntaub ntawv no, nws yuav siv cov system nco, thiab cov qhov tso zis connector yog soldered rau lub motherboard. Cov kev ua tau ntawm cov kev daws muab cov sab nraud counterparts.
