Tom qab NVIDIA tau qhia txog lub sijhawm tiag tiag ntawm txoj kab hluav taws xob ntawm GeForce RTX series video phaib, nws nyuaj rau tsis ntseeg tias cov thev naus laus zis no (hauv kev tsim nyog ua ke nrog rasterization algorithm) yog yav tom ntej ntawm kev ua si hauv computer. Txawm li cas los xij, GPUs raws li Turing architecture nrog tshwj xeeb RT cores tau txog rau thaum nyuam qhuav suav hais tias tsuas yog qeb ntawm GPUs discrete uas muaj lub tshuab xam zauv tsim nyog rau qhov no.
Raws li kev sim ntawm thawj qhov kev ua si uas tau paub txog Ray Tracing (Battlefield V, Metro Exodus thiab Duab Ntxoo ntawm Tomb Raider) tau pom, txawm tias GeForce RTX accelerators (tshwj xeeb tshaj yog tus yau tshaj ntawm lawv, RTX 2060) muaj kev poob qis hauv cov nqi hauv hybrid rendering hauj lwm. Txawm hais tias muaj kev vam meej thaum ntxov, lub sij hawm ntawm txoj kab hluav taws xob tracing tseem tsis tau paub txog technology. Tsuas yog thaum tsis tsuas yog cov khoom siv siab tshaj plaws thiab kim tshaj plaws, tab sis kuj tseem nruab nrab cov duab kos duab tau ncav cuag cov qauv kev ua tau zoo ib yam hauv cov nthwv dej tshiab ntawm kev ua si, nws puas tuaj yeem tshaj tawm tias qhov kev hloov pauv tau pib los ntawm Jensen Huang lub tuam txhab thaum kawg tau tshwm sim.
Ray tracing hauv Pascals - qhov zoo thiab qhov tsis zoo
Tab sis tam sim no, thaum tsis muaj ib lo lus tau hais txog yav tom ntej tus neeg ua tiav rau Turing architecture, NVIDIA tau txiav txim siab los txhawb kev nce qib. Ntawm GPU Technology Conference lub hli dhau los, pab pawg ntsuab tau tshaj tawm tias cov accelerators ntawm Pascal chips, nrog rau cov tswv cuab qis kawg ntawm Turing tsev neeg (GeForce GTX 16 series), yuav tau txais cov duab hluav taws xob hauv lub sijhawm tiag tiag ntawm kev ua haujlwm ntawm RTX. - cov khoom lag luam muaj npe. Niaj hnub no, tus tsav tsheb tau cog lus lawm tuaj yeem rub tawm ntawm lub vev xaib official NVIDIA, thiab cov npe ntawm cov khoom siv suav nrog cov qauv ntawm GeForce 10 tsev neeg, pib nrog GeForce GTX 1060 (6 GB version), tus kws tshaj lij TITAN V accelerator ntawm Volta nti, thiab, tau kawg, cov qauv tshiab tuaj txog hauv cov nqi nruab nrab ntawm cov nti TU116 - GeForce GTX 1660 thiab GTX 1660 Ti. Qhov kev hloov tshiab tseem cuam tshuam rau lub laptops nrog rau GPUs sib xws.
Los ntawm txoj kev pom, tsis muaj dab tsi supernatural ntawm no. GPUs nrog kev sib koom ua ke shader tuaj yeem ua tau Ray Tracing ntev ua ntej qhov tshwm sim ntawm Turing architecture, txawm hais tias lub sijhawm ntawd lawv tsis nrawm txaus rau qhov muaj peev xwm ua tau raws li qhov xav tau hauv kev ua si. Tsis tas li ntawd, tsis muaj tus qauv zoo ib yam rau cov txheej txheem software, dua li kaw APIs zoo li tus tswv NVIDIA OptiX. Tam sim no uas muaj DXR txuas ntxiv rau Direct3D 12 thiab cov tsev qiv ntawv zoo sib xws hauv Vulkan programming interface, lub cav ua si tuaj yeem nkag mus rau lawv tsis hais seb GPU puas tau nruab nrog tshwj xeeb logic, tsuav yog tus tsav tsheb muab lub peev xwm no. Turing chips muaj cais RT cores rau lub hom phiaj no, thiab nyob rau hauv Pascal architecture GPU thiab TU116 processor, ray tracing yog siv nyob rau hauv ib tug general-purpose xam hom ntawm ib tug array ntawm shader ALUs.
Txawm li cas los xij, txhua yam peb paub txog Turing architecture los ntawm NVIDIA nws tus kheej qhia tias Pascal tsis haum rau DXR-enabled applications. Hauv kev nthuav qhia xyoo tas los no tau mob siab rau cov qauv zoo tshaj plaws ntawm tsev neeg Turing - GeForce RTX 2080 thiab RTX 2080 Ti - engineers nthuav tawm cov kev suav hauv qab no. Yog tias koj pov tag nrho cov peev txheej ntawm cov neeg siv khoom zoo tshaj plaws ntawm daim npav thib peb - GeForce GTX 1080 Ti - rau hauv cov duab hluav taws xob tracing, qhov kev ua tau zoo yuav tsis tshaj 11% ntawm qhov RTX 2080 Ti yog qhov muaj peev xwm ua tau. Qhov tseem ceeb sib npaug yog tias cov dawb CUDA cores ntawm Turing nti tuaj yeem siv rau tib lub sijhawm ua haujlwm sib luag ntawm lwm cov duab cov khoom - ua tiav cov kev pabcuam shader, ib kab ntawm cov duab tsis-graphical Direct3D xam thaum lub sijhawm ua tiav asynchronous, thiab lwm yam.
Hauv kev ua si tiag tiag, qhov xwm txheej nyuaj dua, vim hais tias ntawm cov khoom siv kho vajtse uas twb muaj lawm siv DXR ua haujlwm hauv koob, thiab tus tsov ntxhuav feem ntawm kev suav cov load tseem nyob ntawm rasterization thiab cov lus qhia shader. Tsis tas li ntawd, qee qhov cuam tshuam ntau yam uas tau tsim los ntawm kev siv hluav taws xob tracing kuj tuaj yeem ua tiav zoo ntawm CUDA cores ntawm Pascal chips. Piv txwv li, daim iav qhov chaw hauv Battlefield V tsis hais txog qhov kev xav ntawm cov rays, thiab yog li ntawd yog qhov ua tau rau cov ntawv teev lus muaj zog ntawm cov tiam dhau los. Tib yam siv tau rau cov duab ntxoov ntxoo hauv Duab ntxoov ntxoo ntawm Tomb Raider, txawm hais tias ua kom cov duab ntxoov ntxoo nyuaj tsim los ntawm ntau qhov chaw teeb pom kev zoo twb yog ib txoj haujlwm nyuaj dua. Tab sis kev pabcuam thoob ntiaj teb hauv Metro Exodus yog qhov nyuaj txawm tias Turing, thiab Pascal tsis tuaj yeem cia siab tias yuav tsim cov txiaj ntsig sib piv rau txhua qhov.
Txawm ib tug yuav hais li cas, peb tab tom tham txog ntau qhov sib txawv hauv kev ua tau zoo ntawm cov neeg sawv cev ntawm Turing architecture thiab lawv cov analogues ze tshaj ntawm Pascal silicon. Ntxiv mus, tsis tsuas yog muaj RT cores, tab sis kuj muaj ntau yam kev txhim kho cov yam ntxwv ntawm cov tiam tshiab accelerators ua si hauv Turing qhov kev nyiam. Yog li, Turing chips tuaj yeem ua haujlwm sib luag ntawm cov ntaub ntawv tiag (FP32) thiab cov lej (INT), nqa ntau qhov chaw khaws cia hauv zos thiab cais CUDA cores rau kev txiav txim siab txo qis (FP16). Tag nrho qhov no txhais tau hais tias Turing tsis yog tsuas yog ua haujlwm rau cov kev pabcuam shader zoo dua, tab sis kuj tuaj yeem suav cov duab hluav taws xob tracing kuj zoo yam tsis muaj cov block tshwj xeeb. Tom qab tag nrho, dab tsi ua rau rendering siv Ray Tracing yog li cov peev txheej-intensive tsis yog tsuas yog thiab tsis muaj ntau qhov kev tshawb fawb txog kev sib tshuam ntawm cov duab hluav taws xob thiab cov duab geometry (uas RT cores ua), tab sis kev suav cov xim ntawm qhov sib tshuam (shading). Thiab los ntawm txoj kev, cov npe zoo ntawm Turing architecture tag nrho siv rau GeForce GTX 1660 thiab GTX 1660 Ti, txawm hais tias TU116 nti tsis muaj RT cores, yog li kev sim ntawm cov phaib video nrog software ray tracing yog qhov txaus siab tshwj xeeb.
Tab sis txaus txoj kev xav, vim tias peb twb tau sau cov ntaub ntawv ntawm kev ua tau zoo ntawm "Pascals" (nrog rau cov hluas "Turings") hauv Battlefield V, Metro Exodus thiab Duab Ntxoo ntawm Tomb Raider raws li peb tus kheej ntsuas. Nco ntsoov tias tsis yog tus tsav tsheb lossis cov kev ua si lawv tus kheej kho cov duab hluav taws xob txhawm rau txo cov load ntawm GPUs yam tsis muaj RT cores, uas txhais tau hais tias qhov zoo ntawm cov teebmeem ntawm GeForce GTX thiab GeForce RTX yuav tsum zoo ib yam.
