Graphics Vs Video Card
Hauv lub computer, ib qho ntawm cov txiaj ntsig tseem ceeb yog cov zaub. Yog li, lub peev xwm los muab cov khoom tso tawm tau muab tso rau hauv lub motherboard (qhov tseem ceeb ntawm lub system). Qhov no tso cai rau cov khoos phis tawj los muab cov duab tso tawm. Tab sis feem ntau qhov ua tau zoo ntawm cov yeeb yaj kiab tso tawm qis nrog cov khoom siv video onboard, feem ntau hu ua cov duab chipset. Tsis tas li ntawd, thaum rendering 3D graphics thiab lwm yam xav tau graphics ua hauj lwm, lub computer kev ua tau zoo yuav qeeb thiab cov duab tsis meej thiab faulty.
txhawm rau txhim kho qhov zoo ntawm cov duab ntawm lub khoos phis tawj, kho vajtse ntxiv, tshwj xeeb tsim los rau lub hom phiaj no, tuaj yeem txuas nrog los ntawm qhov nthuav dav. Cov cuab yeej kho vajtse no hu ua daim npav daim npav, daim npav video, cov duab accelerator, video accelerator, thiab lwm yam. Qhov tseeb, daim npav daim npav thiab daim npav video yog ib qho thiab tib yam. Lawv tuaj yeem txuas nrog lub computer motherboard los ntawm ISA, MCA, VLB, PCI, AGP, PCI-X, thiab PCI Express interfaces ntawm motherboard.
Cov khoom tseem ceeb ntawm daim npav video thiab lawv txoj haujlwm tau piav qhia luv luv hauv qab no.
• Graphical Processing Unit (GPU) –
GPU yog cov txheej txheem tshwj xeeb nrog cov duab ua haujlwm siab, tshwj xeeb tshaj yog txhawb nqa 3D duab. Nws kuj ua cov duab raws li qhov encoding siv hauv qhov pom.
• Video Bios
Muaj cov duab daim npav qhov chaw, thiab tswj hwm tus cwj pwm ntawm daim npav duab.
• Video Memory
Khaws cov duab ua tiav los ntawm GPU ua ntej tso tawm rau ntawm cov khoom siv.
• RAMDAC (Random Access Memory Digital-Analog Converter)
Hloov cov zis digital los ntawm GPU rau hauv cov cim analog, tom qab ntawd tso tawm rau ntawm cov saib; Tus nqi refresh ntawm daim npav daim npav yog txiav txim siab los ntawm qhov zaus ntawm RAMDAC.
• Output Interface
Cov zis interface muab cov khoom txuas txuas rau cov teeb liab tso tawm kom xa mus rau cov khoom siv. Cov zis interfaces tuaj yeem yog ib qho ntawm nws los ntawm VGA, Digital Visual Interface (DVI), S-Video, HDMI, DMS-59, mus rau DisplayPort thiab lwm yam khoom siv cuam tshuam.
Ib daim npav duab siv lub zog ntawm tus nqi siab thiab, yog li ntawd, nws dissipates ntau thermal zog. Yog li ntawd, cov khoom siv hluav taws xob txaus thiab cov dab dej kub yuav tsum muaj rau kev ua haujlwm zoo ntawm daim npav daim npav. Feem ntau cov dab dej kub thiab cov kiv cua tau teeb tsa rau ntawm daim npav nws tus kheej.
