AMD RX Vega series Tshiab nta

Mar 14, 2019

Vega lub hom phaj siab nce lus qhia ib moos, siab dua moos speeds, thiab kev txhawb rau HBM2. [19] [20] [21]


AMD Vega nta tshiab nco hierarchy nrog high-bandwidth cache thiab nws cov maub los


Kev txhawb rau HBM2 featuring ob npaug ntawm bandwidth-ib-tus pin dhau los ntawm HBM. HBM2 pub kom muaj zog dua qub nrog tsawg tshaj ib nrab ntawm cov cim ntawm GDDR5 nco. Vega architecture yog optimized rau streaming heev datasets thiab muaj peev xwm ua hauj lwm nrog ntau hom kev nco nrog mus txog 512TB ntawm virtual chaw chaw.


Thawj ntxoov ntxoo rau kev txhim kho geometry. Hloov vertex thiab geometry shaders nyob rau hauv geometry ua cov kav dej nrog nrog ib tus qauv tsim tau ib theem. Thawj theem ntxoov ntxoo theem pib dua, qhia txog kev ua kom lub ntsej muag nce siab thiab nce mus dhau.


NCU: Tom ntej Compute Unit ib lub cim ntxiv tom ntej no cav. Vega GPU qhia txog tus Txheej Txheem Rov Tom Qab-Txheej Txheem. Versatile architecture featuring saj zawg zog comput units uas tau natively txheej txheem 8-ntsis, 16-ntsis, 32-ntsis los yog 64-ntsis haujlwm hauv txhua lub voj voog sais. Thiab khiav ntawm ntau dua frequencies. Vega coj cov kev txhawb nqa rau Kev Txiav Txim Siab Zej Zog, ua ob txoj kev ua tiav (16-ntsis) tib lub sij hawm xws li ib qho 32-ntsis floating-point operation. Mus txog 32 32-ntsis, 256 16-ntsis los yog 512 8-ntsis ops ib moos yog tau nrog Vega architecture.


Kos Kwj Binning Rasterizer tsim rau kev ua tau zoo dua thiab muaj hwj chim ua tau zoo. Nws tso cai rau "nqa ib zaug, ntxoov ntxoo ib zaug" ntawm pixels los ntawm kev siv lub ntse rau ntiv nplais qhwv thiab culling thaum ntxov ntawm pixels pom nyob rau hauv ib qhov kawg scene.


Vega qog Direct3D feature theem txhawb los ntawm 12_0 mus rau 12_1.


Vega's rasteriser coj kev txhawb kho-acceleration rau Rasterizer Ordered Views thiab Conservative Rasterisation Tier 3.
