Emva kokuba i-NVIDIA ibonise umkhondo we-ray yexesha lokwenyani kumakhadi evidiyo e-GeForce RTX, kunzima ukuthandabuza ukuba obu buchwepheshe (ngokudityaniswa okufanelekileyo kunye ne-rasterization algorithm) likamva lemidlalo yekhompyuter. Nangona kunjalo, ii-GPUs ezisekwe kuyilo lwe-Turing olunee-cores ezikhethekileyo ze-RT bezijongwa mva nje koluhlu lwee-GPU ezidityanisiweyo ezinamandla okuba zilungele oku.
Njengoko iimvavanyo zemidlalo yokuqala eye yafumana iRay Tracing (iBattlefield V, iMetro Eksodos kunye neShadow yeTomb Raider) ibonisile, kunye neGeForce RTX accelerators (ingakumbi oyena mncinane kubo, iRTX 2060) amava okuhla okubalulekileyo kwireyithi yesakhelo kwi. imisebenzi yokubonelela ngomxube. Ngaphandle kweempumelelo zakwangoko, ukulandelela imitha yexesha lokwenyani akukabi bubugcisa obuqolileyo. Kuphela xa kungekuphela nje ezona zixhobo ziphambili kwaye zibiza kakhulu, kodwa namakhadi emizobo yodidi oluphakathi afikelela kwimigangatho efanayo yokusebenza kumaza amatsha emidlalo, kuya kuba nako ukubhengeza ukuba utshintsho lweparadigm oluqaliswe yinkampani kaJensen Huang luye lwenzeka ekugqibeleni.
Umkhondo weRay kwiPascals - iinzuzo kunye nokubi
Kodwa ngoku, ngelixa kungekho lizwi lithethiweyo malunga nomntu oza kungena ezihlangwini zeTuring, i-NVIDIA ithathe isigqibo sokukhuthaza inkqubela. Kumsitho weNkomfa yeTekhnoloji ye-GPU kwinyanga ephelileyo, iqela eliluhlaza libhengeze ukuba i-accelerators kwi-chips zePascal, kunye namalungu asezantsi osapho lwe-Turing (uchungechunge lwe-GeForce GTX 16), baya kufumana ukusebenza kwexesha lokwenyani lomkhondo we-ray ngokuhambelana ne-RTX. -imveliso enegama. Namhlanje, umqhubi othenjisiweyo unokukhutshelwa kwiwebhusayithi esemthethweni ye-NVIDIA, kwaye uluhlu lwezixhobo lubandakanya iimodeli zentsapho ye-GeForce 10, ukuqala nge-GeForce GTX 1060 (i-6 GB version), i-TITAN V ye-accelerator kwi-chip ye-Volta, kwaye, ngokuqinisekileyo, iimodeli ezisanda kufika kudidi lwexabiso eliphakathi kwi-chip TU116 - GeForce GTX 1660 kunye ne-GTX 1660 Ti. Uhlaziyo lukwachaphazele iilaptops ezineeGPU ezihambelanayo.
Ukusuka kumbono wobugcisa, akukho nto ingaphezu kwendalo apha. Ii-GPU ezineeyunithi ze-shader ezidibeneyo zazikwazi ukwenza iRay Tracing kwakudala ngaphambi kokufika kwe-architecture ye-Turing, nangona ngelo xesha babengakhawulezi ngokwaneleyo ukuba obu buchule bube yimfuneko kwimidlalo. Ukongeza, bekungekho mgangatho ufanayo weendlela zesoftware, ngaphandle kwee-API ezivaliweyo njenge-NVIDIA OptiX yobunini. Ngoku kukho ukongezwa kwe-DXR ye-Direct3D 12 kunye namathala eencwadi afanayo kwi-interface ye-Vulkan yeprogram, injini yomdlalo inokufikelela kuyo nokuba i-GPU ixhotyiswe ngengqiqo ekhethekileyo, okoko nje umqhubi ebonelela ngobu buchule. Iitshiphusi ze-Turing zinee-RT cores ezahlukeneyo zale njongo, kwaye kwi-Pascal architecture GPU kunye ne-TU116 iprosesa, ukulandelwa kwe-ray kuphunyezwa kwifomathi ye-computing yenjongo ngokubanzi kuluhlu lwe-shader ALUs.
Nangona kunjalo, yonke into esiyaziyo malunga noyilo lwe-Turing evela kwi-NVIDIA ngokwayo icebisa ukuba iPascal ayilungelanga usetyenziso olunikwe amandla yi-DXR. Kwinkcazo yonyaka ophelileyo enikezelwe kwiimodeli zeflegi yosapho lweTuring - iGeForce RTX 2080 kunye neRTX 2080 Ti - iinjineli zibonise ezi zibalo zilandelayo. Ukuba uphosa zonke izibonelelo zekhadi lemifanekiso yabathengi ebalaseleyo kwisizukulwana sokugqibela - iGeForce GTX 1080 Ti - kwizibalo zokulandelela iray, ukusebenza okubangelwayo akuyi kudlula i-11% yento i-RTX 2080 Ti ekwazi ngayo. Okubaluleke ngokulinganayo kukuba ii-cores ze-CUDA zamahhala ze-chip ye-Turing zingasetyenziselwa ukusetyenzwa okufanayo kwamanye amacandelo omfanekiso - ukuphunyezwa kweenkqubo ze-shader, umgca wezibalo ze-Direct3D ezingekho graphical ngexesha lokubulawa kwe-asynchronous, njalo njalo.
Kwimidlalo yokwenyani, imeko inzima ngakumbi, kuba kubaphuhlisi behardware abakhoyo basebenzisa imisebenzi ye-DXR kwiidosi, kwaye isabelo sengonyama somthwalo wekhompyuter sisahlala kwi-rasterization kunye nemiyalelo ye-shader. Ukongeza, ezinye zeempembelelo ezahlukeneyo ezidalwe kusetyenziswa ukulandelwa kwe-ray nazo zinokwenziwa kakuhle kwii-CUDA cores zePascal chips. Umzekelo, imiphezulu yesipili kwi-Battlefield V ayithethi ukubonakaliswa kwesibini kwemitha, kwaye ke ngumthwalo onokwenzeka wamakhadi evidiyo anamandla esizukulwana sangaphambili. Oku kufana nezithunzi kwi-Shadow ye-Tomb Raider, nangona ukunikezelwa kwezithunzi eziyinkimbinkimbi ezenziwe yimithombo yokukhanya emininzi sele kungumsebenzi onzima ngakumbi. Kodwa ukugutyungelwa kwehlabathi kwi-Metro Eksodos kunzima nakwiTuring, kwaye uPascal akunakulindeleka ukuba avelise iziphumo ezithelekisekayo nangawuphi na umlinganiselo.
Nokuba umntu uthini na, sithetha ngomahluko ophindaphindiweyo ekusebenzeni kwethiyori phakathi kwabameli boyilo lwe-Turing kunye ne-analogues yabo esondeleyo kwi-silicon yePascal. Ngaphaya koko, ingeyiyo kuphela ubukho be-RT cores, kodwa kunye nophuculo oluninzi oluqhelekileyo lwe-accelerator yesizukulwana esitsha idlala ngokuthanda kukaTuring. Ngaloo ndlela, ii-chips ze-Turing zingenza imisebenzi ehambelanayo kwi-real (FP32) kunye ne-integer (INT) yedatha, ithwala inani elikhulu lememori ye-cache yendawo kunye ne-cores ye-CUDA eyahlukileyo yokubala okuchanekileyo (FP16). Konke oku kuthetha ukuba iTuring ayiphathi kuphela iinkqubo ze-shader ngcono, kodwa inokubala umkhondo weray ngokufanelekileyo ngaphandle kweebhloko ezikhethekileyo. Emva kwayo yonke loo nto, yintoni eyenza unikezelo kusetyenziswa iRay Tracing ngokobutyebi-olunzulu alukho kuphela kwaye alukho kakhulu ukukhangela iindlela zokuhlangana phakathi kwemitha kunye nezinto zejometri (ezo RT cores zenza), kodwa ukubalwa kombala kwindawo yokuhlangana (shading). Kwaye ngendlela, izibonelelo ezidweliswe kwi-architecture ye-Turing isebenza ngokupheleleyo kwi-GeForce GTX 1660 kunye ne-GTX 1660 Ti, nangona i-chip ye-TU116 ingenayo i-RT cores, ngoko ke iimvavanyo zala makhadi evidiyo kunye ne-software ray tracing inomdla othile.
Kodwa i-theory eyaneleyo, kuba sele siqokelele idatha malunga nokusebenza kwe "Pascals" (kunye nabancinci "iiTurings") kwi-Battlefield V, i-Metro Exodus kunye ne-Shadow ye-Tomb Raider ngokusekelwe kwimilinganiselo yethu. Qaphela ukuba akukho mqhubi okanye imidlalo ngokwayo ilungelelanisa inani lemitha ukwenzela ukunciphisa umthwalo kwii-GPU ngaphandle kwe-RT cores, oku kuthetha ukuba umgangatho weempembelelo kwi-GeForce GTX kunye ne-GeForce RTX kufuneka ifane.

Imfazwe V
Ngenxa yokuba i-Battlefield V ngokwayo ngumdlalo olula ngokufanelekileyo (ingakumbi kwiimowudi ze-1080p kunye ne-1440p), kwaye isebenzisa i-ray tracing kwi-patches, ukuvavanya i-GeForce 10-series kunye nenketho ye-DXR ivelise iziphumo ezikhuthazayo. Nangona kunjalo, kuzo zonke iimodeli ngaphandle kwenkxaso kaRay Tracing kwinqanaba le-silicon, kuye kwafuneka sizithintele kwiimodeli ze-GTX 1070/1070 Ti kunye ne-GTX 1080/1080 Ti. Imidlalo yoBugcisa bobuchwephesha isabela ngokurhanelwa kutshintsho oluthe gqolo kuqwalaselo lwehardware kwaye ivalele umsebenzisi kangangesithuba seentsuku ezininzi. Ke ngoko, imilinganiselo yokusebenza yeGeForce GTX 1060 kunye nezixhobo ezimbini zeGeForce GTX 16 ziya kuvela kweli nqaku kamva, nje ukuba iBattlefield V isuse izithintelo kumatshini wethu wovavanyo.
Ngokweepesenti, nabaphi na abathathi-nxaxheba bovavanyo baye bafumana malunga nokuhla okufanayo ekusebenzeni kwiisetingi zomgangatho wokulandela umkhondo we-ray, nokuba sisiphi na isisombululo sesikrini. Ngaloo ndlela, ukusebenza kwamakhadi evidiyo phantsi kwe-brand ye-GeForce RTX 20 iyancipha nge-28-43% enemiphumo ephantsi kunye nephakathi ye-DXR, kunye ne-37-53% enomgangatho ophezulu kunye nomgangatho ophezulu.
Ukuba sithetha ngeemodeli ezindala zosapho lwe-GeForce 10, ke kumanqanaba asezantsi kunye naPhakathi okulandela imitha umdlalo uphulukana ne-36 ukuya kwi-42% ye-FPS, kwaye kumgangatho ophezulu (useto oluphezulu kunye ne-Ultra) i-DXR sele isitya i-54-67. % yomlinganiselo wesakhelo. Qaphela ukuba kuninzi, ukuba akunjalo, i-Battlefield V yemidlalo yemidlalo akukho mahluko ubonakalayo phakathi kweseto ePhantsi kunye nePhakathi, okanye phakathi kwePhakamileyo kunye ne-Ultra, malunga nokucaca komfanekiso okanye ukusebenza. Ngethemba lokuba iiPascal GPUs ziya kuba novakalelo ngakumbi kolu seto, siye saqhuba iimvavanyo kuzo zone iisetingi. Ngokwenene, umahluko othile uvele, kodwa kuphela kwisisombululo se-2160p kwaye ngaphakathi kwe-6% yeFPS.
Ngokwemigaqo epheleleyo, naziphi na ii-accelerators ezindala kwii-chips ze-Pascal zinokugcina amaxabiso efreyimu ngaphezulu kwe-60 FPS kwimowudi ye-1080p enomgangatho oncitshisiweyo wokubonisa, kwaye i-GeForce GTX 1080 Ti ibango isiphumo esifanayo naxa ilandela inqanaba eliphezulu.
