CUDA Cores Piav Qhia
CUDA, ua ib lo lus cim rau Compute Unified Device Architecture, yog ib lub tshuab uas tsim los ntawm Nvidia uas ua haujlwm kom sai tias qhov kev sib txuas ntawm GPU.
Nrog CUDA, soj ntsuam ntawm thiab software developers xa tau C, C ++, thiab Fortran code ncaj nraim mus rau GPU yam tsis siv txoj cai sib dhos. Qhov no cia lawv ua kom zoo dua ntawm cov txheej txheem sib luag ntawm cov txhiab ntawm cov dej num, los yog cov npe, raug nplua ib txhij.
Cov ntaub ntawv ntawm CUDA Cores
Koj tuaj yeem pom lub sij hawm CUDA thaum mus yuav khoom Nvidia video card . Yog koj saib lub thawv ntim ntawm daim npav lossis nyeem video daim ntawv txheeb xyuas, koj yuav pom ntau tus cim rau CUDA cores.
CUDA lub cores yog parallel processors zoo li tus processor hauv computer, uas yog ib qho processor lossis dual quad-core. Nvidia GPUs, txawm li cas los xij, tej zaum yuav muaj ntau txhiab cores. Cov cores no muaj feem xyuam rau ntau yam dej num uas tso cai rau cov cores los txuas ncaj qha rau kev ceev thiab lub zog ntawm GPU.
Txij li cov CUDA lub caws dej yog lub luag hauj lwm rau kev soj ntsuam nrog tag nrho cov ntaub ntawv uas txav los ntawm ib lub GPU, qhov core kov yam li graphics hauv video games rau tej xwm txheej xws li thaum cov cim thiab scenery yog loading.
Cov ntawv thov tuaj yeem ua tau los ua kom zoo dua ntawm kev nce kev ua haujlwm ntxiv los ntawm CUDA cores. Koj tuaj yeem pom daim ntawv teev npe ntawm cov ntawv sau npe ntawm Nvidia's GPU Applications.
CUDA qhov qhab nia yog zoo li AMD lub kwj cag; lawv 're npe xwb. Txawm li cas los, koj yuav tsis equate ib 300 CUDA Nvidia GPU nrog ib tug 300 Kwj Processor AMD GPU.
Xaiv ib daim video nrog CUDA
Ntau dua CUDA cores feem ntau txhais tau hais tias daim video card muab kev ua tau zoo dua tag nrho. Txawm li cas los, tus naj npawb ntawm CUDA lub cores tsuas yog ib qho ntawm ntau yam xav txog thaum xaiv ib daim video .
Nvidia muaj ntau ntau cov ntawv teev lus uas muaj ntau yam li 8 CUDA cores, zoo li hauv GeForce G100, kom ntau li 5,760 CUDA cores hauv GeForce GTX TITAN Z.
Graphics cards uas muaj Tesla, Fermi, Kepler, Maxwell, los yog Pascal architecture txhawb CUDA.
