Cov niaj hnub siv GPUs feem ntau lawv cov transistors los ua cov lus hais txog 3D computer graphics. Ntxiv nrog rau qhov 3D hardware, hnub no lub GPUs muaj xws li theem pib 2D acceleration thiab framebuffer peev xwm (feem ntau yog nrog hom VGA compatibility). Newer cards li AMD / ATI HD5000-HD7000 txawm tias tsis muaj 2D acceleration; nws yuav tsum tau emulated los ntawm 3D hardware. GPUs tau pib siv los ua kom txoj haujlwm nco-intensive ua hauj lwm ntawm kev ntxhib los mos thiab kev ua cov duab, tom qab ntxiv rau cov lej ua kom cov lej geometric suav xws li kev sib hloov thiab txhais lus ntawm cov kab ntawv sib txawv hauv cov kev sib koom tes sib txawv. Cov kev tsim kho tsis ntev los no hauv GPUs muaj xws li kev pab cuam rau cov khoom siv khoos kas uas muaj peev xwm tswj tau cov duab thiab textures nrog ntau cov haujlwm tib yam los ntawm CPUs, oversampling thiab interpolation cov tswv yim los txo cov kev cai, thiab muaj cov xim zoo heev. Vim tias feem ntau ntawm cov lej no muaj kev cuam tshuam cov qauv matrix thiab cov vector, engineers thiab scientists tau nce kev tshawb nrhiav kev siv cov GPUs rau cov graphical uas tsis yog graphical; lawv yog qhov zoo tshaj plaws rau lwm qhov teeb meem ntawm cov teeb meem uas txaj muag.


Nrog qhov tshwm sim ntawm kev kawm tob, qhov tseem ceeb ntawm GPUs tau nce. Hauv kev tshawb fawb los ntawm Indigo, nws pom tau tias thaum txoj kev kawm tob hauv neural networks, GPUs tau 250 zaus ceev dua CPU. Txoj kev loj hlob ntawm kev sib sib zog nqus ntawm kev sib sib zog nqus hauv xyoo tas los no yog los ntawm qhov tshwm sim ntawm cov hom phiaj GPU xwb. Txawm li cas los xij, cov no yuav tsum tau hloov rau cov cai uas twb muaj lawm thiab GPUs tseem nrov heev.
