Chav ua haujlwm hauv graphics (GPU) yog ib qho hluav taws xob hauv hluav taws xob tsim kom ceev ceev thiab hloov qhov cim xeeb kom ua qhov kev tsim cov duab hauv ib qho tsis ua rau cov khoom tso tawm. GPUs yog siv rau hauv lub tshuab kos, cov xov tooj ntawm tes, cov tshuab computer, chaw ua haujlwm, thiab kev sib tw game consoles. Niaj hnub GPUs yog txuag heev ntawm kev siv computer graphics thiab kev ua duab. Lawv cov qauv ua qauv sib luag ua rau lawv ntau tshaj li cov hom phiaj-CPUs rau algorithms uas ua cov txheej txheem loj ntawm cov ntaub ntawv hauv kev ua haujlwm. Nyob rau hauv ib lub tshuab computer, ib tug GPU tuaj yeem yuav muaj nyob rau hauv daim video lossis kos rau ntawm daim duab qhia ntawv. Hauv qee cov CPUs, lawv tau nyob rau ntawm CPU tuag.


Lub sij hawm GPU tau siv los ntawm qhov tsawg xyoo 1980s. Nws tau nrov npe los ntawm Nvidia hauv 1999, leej twg muag GeForce 256 li "lub ntiaj teb thawj GPU". Nws tau hais ua "ib leeg-chip processor nrog kev txuam, teeb pom kev zoo, teeb vaj tse / clipping, thiab ua haujlwm tshuab". Rival ATI Technologies coined lub sij hawm "visual processing unit" los yog VPU nrog rau kev tso tawm ntawm Radeon 9700 hauv xyoo 2002.
