Ka dib markii NVIDIA ay soo bandhigtay raadraaca wakhtiga dhabta ah ee kaararka fiidiyowga ee taxanaha ah ee GeForce RTX, way adagtahay in laga shakiyo in tignoolajiyadan (oo si macquul ah loogu daro algorithm rasterization) ay tahay mustaqbalka ciyaaraha kumbuyuutarka. Si kastaba ha noqotee, GPU-yada ku saleysan qaab dhismeedka Turing ee leh xirmooyinka RT-yada gaarka ah ayaa ilaa dhowaan loo tixgeliyey qeybta kaliya ee GPU-yada kala duwan ee leh awoodda xisaabinta ee tan ku habboon.
Sida tijaabooyinka ciyaarihii ugu horreeyay ee ku guulaystey Ray Tracing (Battlefield V, Metro Exodus iyo Shadow of the Tomb Raider) waxay muujiyeen, xitaa GeForce RTX accelerators (gaar ahaan kuwa ugu da'da yar, RTX 2060) waxay la kulmaan hoos u dhac weyn oo ah heerarka qaabdhismeedka gudaha hawlaha isku-dhafan. Inkastoo guulo hore la gaaray, raadinta raajada wakhtiga-dhabta ah wali maaha tignoolajiyada qaangaadhka ah. Kaliya marka aan kaliya ahayn aaladaha ugu horumarsan iyo kuwa qaaliga ah, laakiin sidoo kale kaararka garaafyada dhexe ee dhexdhexaadka ah waxay gaaraan heerar waxqabad oo isku mid ah mowjadda cusub ee ciyaaraha, waxay suurtagal noqon doontaa in la caddeeyo in isbeddelka isbeddelka ee ay bilaabeen shirkadda Jensen Huang uu ugu dambeyntii dhacay.
Raad raadinta Pascals - faa'iidooyinka iyo khasaarooyinka
Laakiin hadda, in kasta oo aan kelmad laga sheegin mustaqbalka mustaqbalka ee dhismaha Turing, NVIDIA waxay go'aansatay inay horumariso. Munaasabaddii Shirka Tiknoolajiyada GPU ee bishii hore, kooxda cagaaran waxay ku dhawaaqday in dardar-geliyayaasha Pascal chips, iyo sidoo kale xubnaha ugu hooseeya ee qoyska Turing (GeForce GTX 16 taxana), ay heli doonaan shaqeynta raadinta waqtiga-dhabta ah ee RTX -alaabooyinka summadaha leh. Maanta, darawalka ballan qaaday mar hore waxaa lagala soo bixi karaa degelka rasmiga ah ee NVIDIA, iyo liiska qalabyada waxaa ka mid ah moodooyinka qoyska GeForce 10, laga bilaabo GeForce GTX 1060 (nooca 6 GB), xirfadlaha TITAN V ee xawaaraha Volta. iyo, dabcan, moodooyinka dhowaan yimid ee qaybta qiimaha dhexe ee chip TU116 - GeForce GTX 1660 iyo GTX 1660 Ti. Cusboonaysiinta ayaa sidoo kale saamaysay laptops-yada GPU-yada u dhigma.
Marka laga eego dhinaca farsamada, ma jiraan wax ka sarreeya halkan. GPU-yada leh unugyo hadh midaysan ayaa awooday inay sameeyaan Ray Tracing muddo dheer ka hor imaanshaha dhismaha Turing, in kasta oo wakhtigaas aanay ahayn kuwo degdeg ah oo awooddan loogu baahan yahay ciyaaraha. Intaa waxaa dheer, ma jirin halbeeg labis ah oo loogu talagalay hababka software, aan ka ahayn API-yada xiran sida NVIDIA OptiX. Hadda oo ay jirto kordhinta DXR ee Direct3D 12 iyo maktabadaha la midka ah ee barnaamijka Vulkan, mashiinka ciyaarta ayaa heli kara iyaga iyada oo aan loo eegin haddii GPU uu ku qalabaysan yahay macquul gaar ah, ilaa inta darawalku bixiyo awooddan. Chips-yada Turing-ka ayaa leh ujeedo gooni ah oo RT ah, iyo Pascal architecture GPU iyo TU116 processor, raadinta raajo waxaa loo hirgeliyay qaab xisaabin guud oo ujeedo leh oo ku saabsan hannaan ALUs ah.
Si kastaba ha noqotee, wax kasta oo aan ka naqaano qaab dhismeedka Turing ee NVIDIA lafteeda ayaa soo jeedinaya in Pascal uusan ku habboonayn codsiyada karti u leh DXR. Bandhigii sanadkii hore ee loogu talagalay moodooyinka calanka ee qoyska Turing - GeForce RTX 2080 iyo RTX 2080 Ti - injineerada ayaa soo bandhigay xisaabinta soo socota. Haddii aad tuurto dhammaan agabka kaararka garaafyada macaamiisha ee ugu wanaagsan jiilkii ugu dambeeyay - GeForce GTX 1080 Ti - xisaabinta raadraaca rayiga, waxqabadka natiijada kama badan doono 11% waxa RTX 2080 Ti aragti ahaan awood u leeyahay. Sidoo kale muhiim ayaa ah in koofiyadaha CUDA ee bilaashka ah ee Chip Turing isla mar ahaantaana loo isticmaali karo isbarbardhigga qaybaha sawirka kale - fulinta barnaamijyada shader, safka xisaabinta Direct3D-ga aan garaafyada ahayn inta lagu jiro fulinta asynchronous, iyo wixii la mid ah.
Ciyaaraha dhabta ah, xaaladdu aad ayay u dhib badan tahay, sababtoo ah kuwa horumariya qalabka hadda jira waxay isticmaalaan hawlaha DXR ee qiyaasaha, iyo qaybta libaaxa ee culeyska xisaabinta ayaa wali lagu hayaa rasterization iyo tilmaamaha shader. Intaa waxaa dheer, qaar ka mid ah saameynaha kala duwan ee la abuuray iyadoo la adeegsanayo raadinta raajo ayaa sidoo kale si fiican loogu fulin karaa koodhka CUDA ee chips Pascal. Tusaale ahaan, muraayadaha muraayadaha ee Battlefield V ma tilmaamayaan milicsiga labaad ee fallaadhaha, sidaas darteed waa culeys macquul ah oo loogu talagalay kaararka fiidiyoowga ah ee jiilkii hore. Isla sidaas oo kale ayaa khuseeysa hadhyada ku yaal Hadhka Raider-ka Tomb, in kasta oo samaynta hadhyo adag oo ay sameeyeen ilo iftiin badan ay durba hawl aad u adag tahay. Laakiin daboolida caalamiga ah ee Metro Exodus way ku adag tahay xitaa Turing, Pascal lama filan karo inuu keeno natiijooyin la mid ah ilaa xad.
Wax kasta oo la odhan karo, waxaan ka hadlaynaa kala duwanaansho badan oo ku saabsan waxqabadka aragtida ee u dhexeeya wakiilada naqshadaha Turing iyo analoogyadooda ugu dhow ee Pascal silicon. Intaa waxaa dheer, ma aha oo kaliya joogitaanka kombuyuutarrada RT, laakiin sidoo kale tiro badan oo horumarin guud ah oo lagu garto dardar-geliyayaasha jiilka cusub ayaa ka ciyaara doorka Turing. Markaa, Turing chips waxay ku fulin karaan hawlgallo isbarbar socda xogta dhabta ah (FP32) iyo integer (INT), waxay sitaan xaddi badan oo xusuusta kaydka deegaanka ah iyo kala soocida koofiyadaha CUDA ee xisaabinta-saxsanaanta la dhimay (FP16). Waxaas oo dhan waxay ka dhigan tahay in Turing aysan si fiican u maareyn oo kaliya barnaamijyada shader-ka, laakiin sidoo kale waxay xisaabin kartaa raadinta raajada si wax ku ool ah iyada oo aan lahayn blocks khaas ah. Ka dib oo dhan, waxa ka dhigaya samaynta isticmaalka Ray Tracing si kheyraad-dhaqaale ah maaha oo kaliya oo maahan wax aad u badan raadinta isgoysyada u dhexeeya fallaadhaha iyo walxaha joomatari (kuwaas oo RT cores ay sameeyaan), laakiin xisaabinta midabka barta isgoyska (hadhka). Iyo habka, faa'iidooyinka liistada ee naqshadaha Turing waxay si buuxda u khuseeyaan GeForce GTX 1660 iyo GTX 1660 Ti, in kasta oo TU116 chip uusan lahayn xirmooyinka RT, markaa imtixaannada kaararka fiidiyowga ee leh raadinta ray-ga software ayaa xiiso gaar ah leh.
Laakiin aragti ku filan, sababtoo ah waxaan horeyba u soo uruurinay xogta waxqabadka "Pascals" (iyo sidoo kale "Turings" da'da yar) ee Battlefield V, Metro Exodus iyo Hooska Qabriga Raider oo ku salaysan cabbiradeena. Ogsoonow in darawalka iyo ciyaaraha laftoodu aysan hagaajinin tirada fallaadhaha si ay u yareeyaan culeyska GPU-yada iyada oo aan la hayn RT cores, taas oo macnaheedu yahay in tayada saamaynta GeForce GTX iyo GeForce RTX ay noqoto mid isku mid ah.

Battlefield V
Sababtoo ah xaqiiqda ah in Battlefield V lafteedu ay tahay ciyaar fudud oo fudud (gaar ahaan 1080p iyo 1440p hababka), waxayna u isticmaashaa raadinta raajada balastar, tijaabinta GeForce 10-taxane leh xulashada DXR waxay keentay natiijooyin dhiirigelin leh. Si kastaba ha noqotee, dhammaan moodooyinka aan lahayn taageerada Ray Tracing ee heerka silikon, waa inaan nafteena ku koobno moodooyinka GTX 1070/1070 Ti iyo GTX 1080/1080 Ti. Ciyaaraha Farshaxanka Elektarooniga ah waxay uga falceliyaan shaki ku saabsan isbeddelada soo noqnoqda ee qaabeynta qalabka waxayna xannibaan isticmaalaha muddo hal ama dhowr maalmood ah. Sidaa darteed, cabbiraadaha waxqabadka ee GeForce GTX 1060 iyo laba aaladaha taxanaha ah ee GeForce GTX 16 ayaa ka soo muuqan doona maqaalkan dambe, isla marka Battlefield V uu ka saaro xannibaadaha mashiinkayaga tijaabada.
Boqolkiiba marka la eego, mid kasta oo ka mid ah ka qaybgalayaasha imtixaanku waxa ay la kulmeen ku dhawaad isla hoos u dhac ku yimi waxqabadka goobaynta tayada ee kala duwan, iyada oo aan loo eegin xallinta shaashadda. Sidaa darteed, waxqabadka kaararka fiidiyowga ee hoos yimaada calaamadda GeForce RTX 20 waxay hoos u dhigtaa 28-43% oo leh saameyn hoose iyo mid dhexdhexaad ah DXR, iyo 37-53% oo leh tayada sare iyo ugu sarreeya.
Haddii aan ka hadleyno moodooyinka da'da weyn ee qoyska GeForce 10, ka dibna heerarka raadinta raajada hooseeya iyo dhexdhexaadka ah ciyaartu waxay lumisaa 36 ilaa 42% FPS, iyo tayada sare (High and Ultra settings) DXR waxay horey u cuntay 54-67 % ee heerka jir Ogsoonow in qaar badan, haddaysan ahayn inta badan, goobaha ciyaarta Battlefield V ma jiro farqi la aqoonsan karo oo u dhexeeya goobaha hooseeya iyo kuwa dhexdhexaadka ah, ama inta u dhaxaysa Sare iyo Ultra, marka la eego muuqaalka muuqaalka ama waxqabadka. Anagoo rajaynayna in Pascal GPU-yadu ay aad ugu nugul yihiin goobtan, waxaanu ku wadnay imtixaano dhammaan afarta goobood. Runtii, kala duwanaansho gaar ah ayaa soo muuqday, laakiin kaliya 2160p xallinta iyo gudaha 6% FPS.
Marka la eego shuruudaha buuxa, mid kasta oo ka mid ah dardar-geliyayaasha da'da weyn ee Chips Pascal waxay ilaalin karaan heerar ka sarreeya 60 FPS ee qaabka 1080p oo leh tayada milicsiga oo hoos u dhacday, iyo GeForce GTX 1080 Ti waxay sheeganeysaa natiijo la mid ah xitaa marka la raadinayo heerka Sare. Laakiin marka aad u guurto 1440p xallinta, kaliya GeForce GTX 1080 iyo GTX 1080 Ti ayaa bixiya qaab raaxaysi leh oo ah 60 FPS ama ka sareeya oo leh tayo hoose ama dhexdhexaad ah, iyo qaabka 4K, mid ka mid ah kaararka jiilkii hore ma laha awood xisaabeed ku habboon ( sida, runtii, Turing kasta marka laga reebo calanka GeForce RTX 2080 Ti).
Haddii aan raadinno isbarbardhigga u dhexeeya dardar-galiyeyaasha gaarka ah ee hoos yimaada GeForce GTX 10 iyo GeForce RTX 20, markaa qaabka ugu wanaagsan ee jiilkii hore (GeForce GTX 1080 Ti), kaas oo ah analoogga GeForce RTX 2080 ee hawlaha wax-qabadka caadiga ah ee aan lahayn DXR, hoos ugu dhacay heerka GeForce RTX 2070 iyada oo la dhimay raadinta tayada raajada, iyo heerarka sare waxay kaliya la dagaalami kartaa GeForce RTX 2060.
