Pib hnub no, cov duab hluav taws xob ntawm lub sijhawm tiag tiag tau txais kev txhawb nqa tsis yog los ntawm GeForce RTX cov duab phaib, tab sis kuj yog xaiv GeForce GTX 16xx thiab 10xx daim npav duab. Lub GeForce Game Npaj 425.31 WHQL tus tsav tsheb, uas muab daim npav video nrog lub luag haujlwm no, tuaj yeem rub tawm los ntawm official NVIDIA lub vev xaib lossis hloov kho los ntawm GeForce Now daim ntawv thov.
Cov npe ntawm daim npav video uas txhawb nqa cov duab hluav taws xob hauv lub sijhawm muaj xws li GeForce GTX 1660 Ti thiab GTX 1660, Titan Xp thiab Titan X (Pascal), GeForce GTX 1080 Ti thiab GTX 1080, GeForce GTX 1070 Ti thiab GTX 1070, ntxiv rau. GeForce GTX version 1060 nrog 6 GB ntawm lub cim xeeb. Tau kawg, ray tracing ntawm no yuav ua haujlwm nrog qee qhov kev txwv piv rau GeForce RTX daim npav duab. Thiab qhov tsawg dua daim npav video, qhov kev txwv yuav muaj zog dua. Txawm li cas los xij, qhov tseeb tias cov tswv ntawm txawm tias tsis muaj zog GeForce GTX 1060 yuav tuaj yeem "kov" cov thev naus laus zis tshiab tsis tuaj yeem tab sis zoo siab.
Thaum GeForce RTX video phaib muaj cov khoos phis tawj tshwj xeeb (RT cores) uas muab cov khoom siv nrawm nrawm rau cov duab hluav taws xob, GeForce GTX video phaib tsuas yog tsis muaj cov ntsiab lus zoo li no. Yog li ntawd, txoj kab hluav taws xob tracing yog siv rau hauv lawv los ntawm DXR txuas ntxiv rau Direct3D 12, thiab cov txheej txheem hluav taws xob yuav raug tswj hwm los ntawm cov lej sib piv zoo tib yam ntawm cov array ntawm CUDA cores.
Txoj hauv kev no, tau kawg, yuav tsis tso cai rau daim npav video raws li Pascal thiab qis dua Turing GPUs los muab tib theem ntawm txoj kab hluav taws xob kev ua tau zoo raws li GeForce RTX series qauv muaj peev xwm. Slides luam tawm los ntawm NVIDIA nrog cov txiaj ntsig ntawm kev ntsuas kev ua tau zoo ntawm ntau daim npav video siv cov duab hluav taws xob qhia qhov sib txawv loj ntawm GeForce RTX thiab GeForce GTX qauv.
Piv txwv li, hauv kev ua si Metro Exodus, qhov chaw teeb pom kev thoob ntiaj teb tau muab siv kev taug qab, tsis muaj GeForce GTX video phaib tuaj yeem muab tau FPS. Txawm hais tias tus chij ntawm cov tiam dhau los, GeForce GTX 1080 Ti, tsuas yog tuaj yeem pom 16,4 fps. Tab sis nyob rau hauv Battlefield V, qhov twg tracing tsuas yog muab kev xav, lub cim ntawm Pascal tiam tseem muaj peev xwm ncav cuag 30 FPS.
Txawm li cas los xij, NVIDIA tau sim daim npav video ntawm qhov siab tshaj plaws cov duab teeb tsa, nrog rau qhov siab tshaj plaws ntawm kev siv hluav taws xob thiab ntawm qhov kev daws teeb meem ntawm 2560 Γ 1440 pixels. Ntawd yog, cov xwm txheej, muab tso rau me me, tsis yog qhov zoo tshaj plaws: tib lub GeForce GTX 2060 hauv Metro Exodus nruab nrab me ntsis ntau dua 34 fps. Nws yuav ua tau kom ua tiav "playable" FPS ntawm daim npav video qub los ntawm kev txo cov kev daws teeb meem thiab cov duab zoo. Tab sis ua ntej ntawm tag nrho cov, lawv cov kev ua tau zoo yuav raug cuam tshuam los ntawm lub teeb tracing siv qhov chaw.
Cia peb nco ntsoov koj tias tam sim no koj tuaj yeem paub txog cov duab hluav taws xob hauv peb qhov kev ua si: Battlefield V, Metro Exodus thiab Duab Ntxoo ntawm Tomb Raider. Nws kuj tseem muaj nyob rau hauv peb qhov demos: Atomic Heart, Kev Ncaj Ncees thiab Kev Xav. Ob leeg hauv kev ua si thiab hauv demos peb tau nthuav tawm nrog ntau yam kev xaiv rau kev siv hluav taws xob tracing. Qee qhov nws yog lub luag haujlwm rau kev xav thiab duab ntxoov ntxoo, thiab lwm qhov nws yog lub luag haujlwm rau lub ntiaj teb illumination.
