Mushure mekunge NVIDIA yaratidza chaiyo-nguva ray kuteedzera paGeForce RTX akatevedzana makadhi evhidhiyo, zvakaoma kupokana kuti tekinoroji iyi (mukubatana zvine musoro neiyo rasterization algorithm) ndiyo ramangwana remitambo yemakomputa. Nekudaro, maGPU akavakirwa paTuring architecture ane hunyanzvi hweRT cores aive kusvika nguva pfupi yadarika akatariswa chete chikamu che discrete maGPU ane simba rekombuta rakakodzera izvi.
Sekuyedzwa kwemitambo yekutanga yakabata Ray Tracing (Battlefield V, Metro Exodus uye Shadow yeTomb Raider) yakaratidza, kunyangwe GeForce RTX accelerators (kunyanya mudiki wavo, iyo RTX 2060) inosangana nekudonha kwakakosha kwemafuremu. hybrid kupa mabasa. Pasinei nekubudirira kwekutanga, chaiyo-nguva yekutevera ray haisati yakura tekinoroji. Chete kana kwete chete michina yepamusoro uye inodhura, asiwo yepakati-renji makadhi emifananidzo asvika kune imwecheteyo maitiro ekuita mumafungu matsva emitambo, zvinogoneka kuzivisa kuti shanduko yeparadigm yakatangwa nekambani yaJensen Huang yakazoitika.
Ray kutsvaga muPascals - zvakanakira uye zvakaipira
Asi ikozvino, kunyangwe pasina kana izwi rakataurwa nezve anotevera mutsivi weTuring architecture, NVIDIA yafunga kukurudzira kufambira mberi. Pamusangano weGPU Technology Musangano mwedzi wapera, timu yakasvibira yakazivisa kuti vanomhanyisa paPascal machipisi, pamwe nenhengo dzekupedzisira dzeTuring mhuri (GeForce GTX 16 nhevedzano), vachawana chaiyo-nguva ray yekutevera mashandiro pamwe neRTX. - branded zvigadzirwa. Nhasi, mutyairi akavimbiswa anogona kutotorwa pawebhusaiti yepamutemo yeNVIDIA, uye rondedzero yemidziyo inosanganisira mhando dzemhuri yeGeForce 10, kutanga neGeForce GTX 1060 (6 GB vhezheni), inyanzvi TITAN V accelerator paVolta chip, uye, hongu, mhando dzichangosvika dziri pakati-yemutengo chikamu pane chip TU116 - GeForce GTX 1660 uye GTX 1660 Ti. Iyo yekuvandudza yakabatawo malaptop ane anowirirana maGPU.
Kubva pakuona kwehunyanzvi, hapana chinhu chinoshamisa pano. MaGPU ane mauniti akabatana shader akakwanisa kuita Ray Tracing nguva refu isati yasvika yeTuring architecture, kunyangwe panguva iyoyo vaive vasina kukurumidza zvakakwana kuti kugona uku kuve kudiwa mumitambo. Pamusoro pezvo, pakanga pasina chiyero chakafanana chemaitiro esoftware, kunze kwekuvharwa maAPI senge muridzi weNVIDIA OptiX. Iye zvino zvave nekuwedzera kweDXR yeDirect3D 12 uye maraibhurari akafanana muVulkan programming interface, injini yemutambo inogona kuvawana zvisinei nekuti iyo GPU ine hunyanzvi hwekufunga, chero mutyairi achipa kugona uku. Turing machipi ane akaparadzana RT cores echinangwa ichi, uye muPascal architecture GPU uye TU116 processor, ray tracing inoitwa mune yakajairika-chinangwa komputa fomati pane akatevedzana shader ALUs.
Nekudaro, zvese zvatinoziva nezve Turing architecture kubva kuNVIDIA pachayo inoratidza kuti Pascal haina kukodzera DXR-inogonesa maapplication. Mumharidzo yegore rapfuura yakatsaurirwa kumhando dzemhando dzemhuri yeTuring - GeForce RTX 2080 uye RTX 2080 Ti - mainjiniya vakaratidza zvinotevera kuverenga. Kana iwe ukakanda zvese zviwanikwa zveakanakisa mutengi giraidhi kadhi yechizvarwa chekupedzisira - iyo GeForce GTX 1080 Ti - mune ray yekutevera kuverenga, mhedzisiro inozoitika haipfuure gumi negumi muzana yezvinogona kuitwa neRTX 11 Ti. Izvo zvakakoshawo ndezvekuti iyo yemahara CUDA cores yeTuring chip inogona panguva imwe chete kushandiswa kuenderana kwezvimwe zvikamu zvemufananidzo - kuurayiwa kwemapurogiramu e shader, mutsara weasiri-graphical Direct2080D kuverenga panguva yeasynchronous execution, zvichingodaro.
Mumitambo chaiyo, mamiriro acho akanyanya kuoma, nekuti pane varipo vanogadzira hardware vanoshandisa DXR mabasa mumadosi, uye chikamu cheshumba chemutoro wekombuta chichiri kugarwa nerasterization uye shader mirairo. Uye zvakare, mamwe eakasiyana mhedzisiro anogadzirwa uchishandisa ray tracing anogona zvakare kuurayiwa nemazvo paCUDA cores yePascal chips. Semuyenzaniso, magirazi enzvimbo muBattlefield V hazvireve chechipiri kuratidzwa kwemwaranzi, uye nekudaro mutoro unogoneka wemakadhi evhidhiyo ane simba echizvarwa chakapfuura. Izvi zvinoshandawo kune mimvuri muMumvuri weTomb Raider, kunyangwe kupa mimvuri yakaoma inoumbwa neakawanda magetsi masosi ratova basa rakaoma. Asi kufukidzwa kwepasi rose muMetro Exodus kwakaomera kunyangwe kuTuring, uye Pascal haigone kutarisirwa kuburitsa mhedzisiro yakafanana kusvika pamwero chero upi zvawo.
Chero zvingataurwa nemunhu, tiri kutaura nezve mutsauko wakawanda mukuita kwedzidziso pakati pevamiriri veTuring architecture uye yavo yepedyo analogues paPascal silicon. Zvakare, kwete chete kuvapo kweRT cores, asiwo kwakawanda kwakawanda kuvandudzwa hunhu hwechizvarwa chitsva chekusimudzira tamba mukufarira kwaTuring. Saka, Turing machipisi anogona kuita mapeche anoenderana pane chaiyo (FP32) uye integer (INT) data, inotakura yakawanda yemunharaunda cache memory uye inoparadzanisa CUDA cores yekuderedzwa-chaiyo macalculation (FP16). Zvese izvi zvinoreva kuti Turing haingobata shader zvirongwa zvirinani, asi inogona zvakare compute ray tracing zvine mutsindo pasina nyanzvi mabhuraki. Mushure mezvose, chii chinoita kuti kupa uchishandisa Ray Tracing saka zviwanikwa-zvakawanda hazvisi chete uye kwete zvakanyanya kutsvaga kwekupindirana pakati pemwaranzi uye geometry zvinhu (izvo zvinoitwa neRT cores), asi kuverenga kweruvara panzvimbo yemharadzano (shading). Uye nenzira, mabhenefiti akanyorwa eiyo Turing architecture anoshanda zvizere kuGeForce GTX 1660 uye GTX 1660 Ti, kunyangwe iyo TU116 chip haina RT cores, saka bvunzo dzeaya makadhi evhidhiyo ane software ray tracing inonyanya kufarira.
Asi dzidziso yakakwana, nekuti isu takatounganidza data pamusoro pekuita kwe "Pascals" (pamwe nevadiki "Turings") muBattlefield V, Metro Exodus uye Shadow yeTomb Raider zvichienderana nezviyero zvedu. Ziva kuti hapana mutyairi kana mitambo pachayo inogadzirisa huwandu hwemwaranzi kuitira kuderedza mutoro paGPU pasina RT cores, zvinoreva kuti mhando yemhedzisiro paGeForce GTX uye GeForce RTX inofanira kufanana.

Battlefield V
Nekuda kwekuti Hondo yeV pachayo mutambo wakareruka (kunyanya pa1080p uye 1440p modhi), uye inoshandisa ray yekutevera mumachira, kuyedza iyo GeForce 10-yakatevedzana neDXR sarudzo yakaburitsa zvinokurudzira. Nekudaro, pamamodheru ese asina Ray Tracing rutsigiro pasilicon level, taifanira kuzviganhurira kune GTX 1070/1070 Ti uye GTX 1080/1080 Ti modhi. Mitambo yeElectroniki Arts inoita nekunyumwira kune kazhinji shanduko mukugadziriswa kwehardware uye kuvharira mushandisi kwenguva yezuva rimwe kana akati wandei. Naizvozvo, kuyerwa kwekuita kweGeForce GTX 1060 uye maviri GeForce GTX 16 akatevedzana maturusi anozoonekwa muchinyorwa chino gare gare, panongoita Hondo V painobvisa zvirambidzo pamushini wedu wekuyedza.
Mumaperesenti, chero wevatori vechikamu muyedzo akawana kudonha kwakafanana mukuita pane akasiyana ray ekutsvaga mhando marongero, zvisinei nekugadziriswa kwescreen. Saka, kuita kwemakadhi evhidhiyo pasi peGeForce RTX 20 mhando inodzikira ne28-43% ine yakaderera uye yepakati mhando DXR mhedzisiro, uye ne37-53% ine yakakwirira uye yakanyanya kunaka.
Kana isu tichitaura nezve ekare mamodheru emhuri yeGeForce 10, ipapo paLow uye Medium ray yekutevera nhanho mutambo unorasikirwa kubva pa36 kusvika 42% yeFPS, uye pamhando yepamusoro (yepamusoro uye Ultra marongero) DXR yatodya kumusoro 54-67. % yechiyero chefuremu. Ziva kuti mune akawanda, kana asiri mazhinji, Battlefield V mutambo wemitambo hapana mutsauko unoonekwa pakati pePazasi neMedium marongero, kana pakati pePamusoro neUltra, maererano nekujeka kwemufananidzo kana kuita. Tichivimba kuti Pascal GPUs yaizonyanya kutarisisa kune iyi gadziriro, takamhanyisa bvunzo pamasetiroti ese mana. Chokwadi, mimwe misiyano yakaonekwa, asi chete pa2160p resolution uye mukati me6% FPS.
Mumashoko akakwana, chero evakuru vekare paPascal machipisi anogona kuchengetedza furemu mareti pamusoro pe60 FPS mu1080p modhi ine yakaderedzwa yemhando yekuratidzira, uye iyo GeForce GTX 1080 Ti inoda mhedzisiro yakafanana kunyangwe ichitsvaga paPamusoro nhanho. Asi kana iwe uchinge waenda kune 1440p resolution, iyo GeForce GTX 1080 uye GTX 1080 Ti chete inopa yakagadzika framerate ye60 FPS kana yepamusoro neLow kana Medium ray yekutevera mhando, uye mu4K modhi, hapana kana makadhi echizvarwa apfuura ane akakodzera komputa simba. se, zvechokwadi, chero Turing kunze kweiyo mureza GeForce RTX 2080 Ti).
Kana tikatsvaga kufanana pakati peanokwidziridza pasi peGeForce GTX 10 uye GeForce RTX 20 mhando, saka yakanakisa modhi yechizvarwa chakapfuura (GeForce GTX 1080 Ti), inova analogue yeGeForce RTX 2080 mune yakajairwa kupa mabasa pasina DXR, yakadonha kusvika pamwero weGeForce RTX 2070 ine yakaderedzwa mhando ray tracing, uye pamazinga akakwirira inogona chete kurwa neGeForce RTX 2060.
