Ina ua maeʻa ona faʻaalia e le NVIDIA le suʻeina o ave i luga o kata vitio faʻasologa o GeForce RTX, e faigata ona masalosalo o lenei tekinolosi (i le fetaui lelei ma le rasterization algorithm) o le lumanaʻi o taaloga komepiuta. Ae ui i lea, o GPU e faʻavae i luga o le fausaga o Turing ma faʻapitoa RT cores na oʻo i le taimi nei na manatu i ai na o le pau lea o le vaega o GPU tuʻufaʻatasia o loʻo i ai le mana faʻakomepiuta talafeagai mo lenei mea.
E pei ona faʻaalia i faʻataʻitaʻiga o taʻaloga muamua na faʻatautaia Ray Tracing (Battlefield V, Metro Exodus ma Shadow of the Tomb Raider), e oʻo lava i le GeForce RTX accelerators (aemaise lava le uii o latou, le RTX 2060) o loʻo i ai se pa'ū tele i fua faʻavaa i totonu. galuega tu'ufa'atasiga. E ui i le vave manuia, o le su'esu'eina o ave i le taimi moni e le'i avea o se tekinolosi matua. E naʻo le taimi e le gata o masini sili ona maualuga ma taugata, ae faʻapea foʻi i le vaeluagalemu o kata faʻataʻitaʻiga e oʻo atu i tulaga tutusa i le galu fou o taʻaloga, o le a mafai ona faʻaalia o le suiga faʻataʻitaʻiga na faʻalauiloaina e le kamupani a Jensen Huang ua iu lava ina faia.
Su'ega Ray i Pascals - lelei ma le lelei
Ae o lenei, e ui e leai se upu na taʻua e uiga i le lumanaʻi e suitulaga i le fausaga o Turing, ua filifili le NVIDIA e faʻaosofia le alualu i luma. I le GPU Technology Conference event i le masina na teʻa nei, na faʻasalalau ai e le 'au lanumeamata e faʻapea o tagata faʻavavevave i Pascal chips, faʻapea foʻi ma tagata pito i lalo o le aiga Turing (GeForce GTX 16 series), o le a maua le faʻatinoina o le suʻeina o ave i le taimi tonu ma le RTX. -oloa fa'ailoga. I aso nei, ua mafai ona sii mai le avetaavale folafolaina i luga o le upega tafaʻilagi aloaia a le NVIDIA, ma o le lisi o masini e aofia ai faʻataʻitaʻiga o le aiga GeForce 10, e amata mai i le GeForce GTX 1060 (6 GB version), le faʻapolofesa TITAN V accelerator i luga o le Volta chip, ma, ioe, faʻataʻitaʻiga fou faatoa taunuu mai i le vaeluagalemu o tau i luga o le pu TU116 - GeForce GTX 1660 ma GTX 1660 Ti. O le fa'afouga na a'afia ai fo'i le komipiuta fa'atasi ma GPU tutusa.
Mai se vaaiga faʻapitoa, e leai se mea faʻapitoa iinei. GPU faʻatasi ai ma iunite faʻapipiʻi tuʻufaʻatasia na mafai ona faʻatino Ray Tracing i se taimi umi aʻo leʻi oʻo mai le fausaga o Turing, e ui lava i lena taimi latou te leʻi vave lava mo lenei gafatia e manaʻomia i taʻaloga. E le gata i lea, e leai se tulaga tutusa mo metotia polokalame, e ese mai i API tapuni e pei o le NVIDIA OptiX. I le taimi nei o loʻo i ai se faʻaopoopoga DXR mo Direct3D 12 ma faletusi tutusa i le Vulkan programming interface, e mafai e le taʻaloga taʻaloga ona maua i latou e tusa lava pe faʻapipiʻiina le GPU i manatu faʻapitoa, pe afai e maua e le avetaavale lenei gafatia. Turing chips e iai 'ese'ese RT cores mo lenei fa'amoemoe, ma i le Pascal architecture GPU ma le TU116 processor, o lo'o fa'atinoina le su'esu'eina o ave i se fa'atulagaina fa'akomupiuta fa'amoemoe lautele i luga o se fa'asologa o ALU shader.
Ae ui i lea, o mea uma tatou te iloa e uiga i le Turing architecture mai le NVIDIA lava ia e taʻu mai ai e le talafeagai Pascal mo DXR-faʻaogaina talosaga. I le tausaga talu ai, na tuʻuina atu i le faʻataʻitaʻiga faʻataʻitaʻiga a le aiga Turing - GeForce RTX 2080 ma RTX 2080 Ti - na tuʻuina atu e le au inisinia faʻatusatusaga nei. Afai e te lafoina uma punaoa o le kata faʻataʻitaʻiga sili ona lelei o le augatupulaga mulimuli - le GeForce GTX 1080 Ti - i faʻatusatusaga o suʻega, o le taunuuga o le a le sili atu i le 11% o le mea e mafai e le RTX 2080 Ti ona mafai. E tutusa le taua o le maua fua ole CUDA cores o le Turing chip e mafai i le taimi lava e tasi ona faʻaaogaina mo le faʻaogaina tutusa o isi vaega o ata - faʻatinoina o polokalame shader, se faʻasologa o faʻatusatusaga Direct3D e le o faʻataʻitaʻi i le taimi o le asynchronous execution, ma isi.
I taʻaloga moni, o le tulaga e sili atu ona faigata, aua o loʻo i ai i le au atinaʻe meafaigaluega o loʻo faʻaaogaina galuega a le DXR i doses, ma o loʻo nofoia pea le vaega a le leona o le uta faʻapipiʻi e le rasterization ma le shader faatonuga. E le gata i lea, o nisi o aʻafiaga eseese e faʻaaogaina e ala i le suʻeina o ave e mafai foi ona faʻatinoina lelei i luga o le CUDA cores o Pascal chips. Mo se faʻataʻitaʻiga, o faʻata i luga o le Battlefield V e le faʻaalia ai le ata lona lua o ave, ma o le mea lea o se uta talafeagai mo kata vitio malolosi o le augatupulaga muamua. E tutusa lava le faʻatatau i ata lafoia i le Ata o le Tomb Raider, e ui o le tuʻuina atu o ata faʻalavelave e fausia e le tele o faʻapogai malamalama o se galuega sili atu ona faigata. Ae o le faʻasalalauga faʻavaomalo i Metro Exodus e faigata e oʻo lava ia Turing, ma e le mafai ona faʻamoemoeina Pascal e maua mai faʻatusatusa iʻuga i soʻo se itu.
Po o le a lava le mea e fai mai ai se tasi, o loʻo matou talanoa e uiga i le tele o eseesega i le faʻatinoga faʻapitoa i le va o sui o le Turing architecture ma a latou faʻataʻitaʻiga vavalalata i luga o le Pascal silicon. E le gata i lea, e le gata o le i ai o le RT cores, ae faʻapea foʻi le tele o faʻaleleia atili o uiga o tupulaga fou faʻavavevave e taʻalo i le fiafia o Turing. O lea la, e mafai e Turing meataalo ona fa'atino galuega tutusa i luga o fa'amaumauga moni (FP32) ma le integer (INT), e ave ai se aofa'iga tele o manatuaga fa'apitonu'u ma tu'ueseese 'au CUDA mo fa'atatauga fa'aititia (FP16). O lona uiga o Turing e le gata e sili atu le taulimaina o polokalame shader, ae e mafai foi ona faʻatusatusaina le suʻeina o ave e aunoa ma ni poloka faʻapitoa. A uma mea uma, o le a le mea e faʻaogaina ai le faʻaogaina o le Ray Tracing e faʻamalosia e le gata ma e le o le tele o le sailiga mo fesoʻotaʻiga i le va o ave ma elemene geometry (lea e fai e RT cores), ae o le faʻatusatusaina o lanu i le vaeluaga (shading). Ma i le ala, o le lisi lisi o le ata o Turing e faʻaaoga atoatoa i le GeForce GTX 1660 ma le GTX 1660 Ti, e ui o le TU116 chip e leai ni pusa RT, o lea o suʻega o nei kata vitio faʻatasi ai ma le suʻesuʻeina o masini komepiuta e sili ona fiafia.
Ae lava le manatu, aua ua uma ona matou aoina faʻamatalaga i luga o le faatinoga o "Pascals" (faʻapea foʻi ma le laʻititi "Turings") i le Battlefield V, Metro Exodus ma le Ata o le Tomb Raider e faʻavae i luga oa tatou lava fua. Manatua e le o le avetaʻavale poʻo le taʻaloga latou te fetuunai le numera o ave ina ia faʻaitiitia ai le uta i luga o GPU e aunoa ma le RT, o lona uiga e tatau ona tutusa le lelei o aʻafiaga i GeForce GTX ma GeForce RTX.
