Qhov kev xaiv ntawm daim npav video rau lub khoos phis tawj ntiag tug tau nqis los txiav txim siab cov haujlwm uas nws yuav tsum tau ua.
Qhov ntsuas tseem ceeb tshaj plaws ntawm lub khoos phis tawm suab suav nrog qhov zaus ntawm qhov tsim cov duab, qhov dav me ntsis ntawm lub tsheb npav cov ntaub ntawv los ntawm cov maub los rau cov ntaus ntawv, qhov ntau ntawm lub cim xeeb thiab nws cov zaus, thiab muaj cov txiaj ntsig tawm video. Nws tseem yog qhov tseem ceeb dab tsi version ntawm shaders daim npav video txhawb hauv kho vajtse. Qhov siab dua tag nrho cov kev ntsuas no, qhov hloov kho kom haum yuav zoo dua, tab sis tus nqi tuaj yeem mus txog tus lej vwm.
Txog cov haujlwm tus qauv, ua haujlwm hauv chaw ua haujlwm siv, Is Taws Nem thiab saib mauv vim, nws txaus los coj daim npav video nrog qhov ua tau tsis zoo, raug nqi txog $ 50. Feem ntau, xws li tus tswj hwm tau nruab nrog 1 GB ntawm GDDR2 RAM thiab lub processor nce txog 600 MHz. Daim npav peev nyiaj no tau nthuav tawm los ntawm cov hom muaj ob hom GeForce thiab Radeon. Tab sis nws yuav tsum tau hais tias tam sim no cov yeeb yaj kiab tshiab tau muab rho tawm, piv txwv li ntawm Blue-Ray discs, tuaj yeem tshwm sim intermittently ntawm cov ntawv teev lus.
Txog kev ua si, kho duab video, koj yuav xav tau daim video card haib dua uas muaj peev xwm daws tau cov kev daws teeb meem siab. Tus nqi ntau ntawm cov kev hloov kho zoo li no muaj ntau heev, pib txij li $ 100. Lub ntsiab tseem ceeb hauv cov ntawv teev lus video yog kho vajtse txhawb rau cov shaders thiab DirectX, tus nqi ntau dua daim npav, cov ntawv siab dua ntawm shaders nws txhawb nqa. Qhov kev xaiv zoo tshaj plaws rau cov kev ua si niaj hnub no yog daim npav daim duab uas txhawb nqa Shader 5 thiab DirectX 11. Rau $ 100, koj tuaj yeem yuav daim npav nrog 2GB ntawm GDDR5 RAM thiab 800 MHz processor.
Rau kev ua haujlwm nrog 3D daim duab thiab ib puag ncig ua qauv, daim npav video rau kev ua si tsis txaus. Cov kev pab cuam xws li 3ds MAX thiab lwm cov 3D ua cov pob khoom xav tau kev yoog mus rau 3D kev suav los ntawm cov hloov mus rau ua haujlwm kom raug. Cov kev hloov kho tshwj xeeb no raug nqi ntau, pib txij li $ 3,000 nyob rau nruab nrab. Lawv siv nyob rau hauv cov lag luam loj ua qauv 3D.
Niaj hnub no daim video card lag luam yog tswj los ntawm ob lub tuam txhab - Ati thiab NVidia. ATI yog feem ntau txhawb nqa Radeon hom, thaum NVidia tab tom txhawb Geforce. Tsis muaj qhov sib txawv ntawm tus nqi sib txawv ntawm lawv, piv txwv li, nyob rau hauv rooj plaub ntawm Amd thiab Intel cov txheej txheem, yog li cov chaw tsim khoom lag luam xaiv los nqis rau ib tus neeg muaj kev xav.
