Ma hope o ka hōʻike ʻana o NVIDIA i ka nānā ʻana i ka hihi manawa maoli ma nā kāleka wikiō GeForce RTX series, paʻakikī ke kanalua ʻo kēia ʻenehana (i ka hui kūpono me ka algorithm rasterization) ka wā e hiki mai ana o nā pāʻani kamepiula. Eia nō naʻe, ʻo nā GPU e pili ana i ka hoʻolālā Turing me nā cores RT kūikawā a hiki i kēia manawa i manaʻo ʻia ʻo ia wale nō ka ʻāpana o nā GPU discrete i loaʻa ka mana computing kūpono no kēia.
E like me nā hoʻokolohua o nā pāʻani mua i haku iā Ray Tracing (Battlefield V, Metro Exodus a me Shadow of the Tomb Raider) i hōʻike ʻia, ʻo GeForce RTX accelerators (ʻoi aku ka muli loa o lākou, ʻo ka RTX 2060) e ʻike i kahi hāʻule nui o nā helu kiʻi ma. nā hana hoʻohālike hybrid. ʻOiai ʻo nā kūleʻa mua, ʻaʻole ia he ʻenehana oʻo ka huli ʻana i ka ray manawa maoli. ʻAʻole wale nā mea ʻoi loa a me ka pipiʻi wale nō, akā hiki i nā kāleka kiʻi waena waena i nā kūlana hana like i ka nalu hou o nā pāʻani, e hiki ke haʻi i ka hoʻololi ʻana o ka paradigm i hoʻokumu ʻia e ka hui ʻo Jensen Huang.
Ka ʻimi ʻana o Ray ma Pascals - nā pono a me nā pōʻino
Akā i kēia manawa, ʻoiai ʻaʻole i ʻōlelo ʻia kahi huaʻōlelo e pili ana i ka mea e hiki mai ana i ka hoʻolālā Turing, ua hoʻoholo ʻo NVIDIA e hoʻoikaika i ka holomua. I ka hanana GPU Technology Conference i ka mahina i hala aku nei, ua hoʻolaha ka hui ʻōmaʻomaʻo e loaʻa i nā mea hoʻokele i nā pahu Pascal, a me nā lālā haʻahaʻa o ka ʻohana Turing (GeForce GTX 16 series), e loaʻa i ka hana ray tracing manawa maoli ma ka par me RTX - nā huahana hōʻailona. I kēia lā, hiki ke hoʻoiho ʻia ka mea hoʻokele i hoʻohiki ʻia ma ka pūnaewele NVIDIA mana, a ʻo ka papa inoa o nā hāmeʻa e pili ana i nā hiʻohiʻona o ka ʻohana GeForce 10, e hoʻomaka ana me ka GeForce GTX 1060 (6 GB version), ka mea hoʻokele TITAN V ʻoihana ma ka chip Volta. a, ʻoiaʻiʻo, nā hiʻohiʻona hou i hōʻea mai i ka waena waena o ke kumu kūʻai ma ka chip TU116 - GeForce GTX 1660 a me GTX 1660 Ti. Ua hoʻopili pū ka mea hou i nā kamepiula me nā GPU pili.
Mai ka ʻike loea, ʻaʻohe mea kupua ma ʻaneʻi. Hiki i nā GPU me nā ʻāpana shader hui ke hana iā Ray Tracing ma mua o ka hiki ʻana mai o ka hale hoʻolālā Turing, ʻoiai i kēlā manawa ʻaʻole lākou wikiwiki no kēia hiki ke koi ʻia i nā pāʻani. Eia kekahi, ʻaʻohe maʻamau like ʻole no nā ʻano polokalamu, ʻokoʻa nā API i pani ʻia e like me ka proprietary NVIDIA OptiX. I kēia manawa aia kahi hoʻonui DXR no Direct3D 12 a me nā hale waihona puke like i ka Vulkan programming interface, hiki i ka mīkini pāʻani ke komo iā lākou inā ʻaʻole i hoʻolako ʻia ka GPU me ka loiloi kūikawā, ʻoiai ke hāʻawi nei ka mea hoʻokele i kēia hiki. He ʻokoʻa ʻē aʻe nā ʻāpana ʻo Turing no kēia kumu, a ma ka papa hana Pascal GPU a me TU116 kaʻina hana, hoʻokō ʻia ka ray tracing ma kahi ʻano hoʻopili helu maʻamau ma kahi o nā ALU shader.
Eia nō naʻe, ʻo nā mea āpau a mākou e ʻike ai e pili ana i ka hoʻolālā Turing mai NVIDIA ponoʻī e hōʻike ana ʻaʻole kūpono ʻo Pascal no nā noi DXR. Ma ka hōʻike o ka makahiki i hala i hoʻolaʻa ʻia i nā hiʻohiʻona poʻokela o ka ʻohana Turing - GeForce RTX 2080 a me RTX 2080 Ti - ua hōʻike nā ʻenekini i nā helu aʻe. Inā ʻoe e hoʻolei i nā kumuwaiwai āpau o ke kāleka kiʻi mea kūʻai aku maikaʻi loa o ka hanauna hope loa - ʻo GeForce GTX 1080 Ti - i ka helu ʻana i ka ray tracing, ʻaʻole e ʻoi aku ka hopena ma mua o 11% o ka mea hiki i ka RTX 2080 Ti. ʻO ka mea nui, hiki ke hoʻohana ʻia nā cores CUDA manuahi o ka chip Turing i ka manawa like no ka hana like ʻana o nā ʻāpana kiʻi ʻē aʻe - ka hoʻokō ʻana i nā polokalamu shader, kahi laina o nā helu Direct3D non-graphical i ka wā o ka hoʻokō asynchronous, a pēlā aku.
Ma nā pāʻani maoli, ʻoi aku ka paʻakikī o ke kūlana, no ka mea, hoʻohana nā mea hoʻomohala lako i nā hana DXR i nā doses, a ʻo ka liona o ka haʻahaʻa computing e noho mau ʻia e ka rasterization a me nā kuhikuhi shader. Eia kekahi, hiki ke hoʻokō maikaʻi ʻia kekahi o nā hopena like ʻole e hoʻohana ana i ka ray tracing ma nā cores CUDA o nā pahu Pascal. No ka laʻana, ʻaʻole i hōʻike ʻia nā aniani aniani i ke kahua kaua V i ka nānā ʻana i nā kukuna lua, a no laila he mea hiki ke hoʻouka ʻia no nā kāleka wikiō ikaika o ka hanauna i hala. Hoʻohana like ia i nā aka ma Shadow of the Tomb Raider, ʻoiai ʻo ka hoʻolilo ʻana i nā aka paʻakikī i hoʻokumu ʻia e nā kumu kukui he ʻoi aku ka paʻakikī. Akā paʻakikī ka uhi honua ma Metro Exodus no Turing, a ʻaʻole hiki ke manaʻo ʻia ʻo Pascal e hana i nā hopena like i kēlā me kēia ʻano.
ʻO kēlā me kēia mea e ʻōlelo ai, ke kamaʻilio nei mākou e pili ana i kahi ʻokoʻa he nui i ka hana theoretical ma waena o nā ʻelele o ka hale hoʻolālā Turing a me kā lākou mau analogues kokoke loa ma Pascal silicon. Eia kekahi, ʻaʻole wale ka hiki ʻana o nā cores RT, akā nui nō hoʻi nā hoʻomaikaʻi maʻamau i ʻike ʻia o nā mea hoʻokele hanauna hou e pāʻani nei i ka makemake o Turing. No laila, hiki i nā ʻāpana Turing ke hana i nā hana like ma ka ʻikepili maoli (FP32) a me ka integer (INT), lawe i ka nui o ka hoʻomanaʻo cache kūloko a me nā cores CUDA hoʻokaʻawale no nā helu helu hōʻemi (FP16). ʻO ke ʻano o kēia mau mea ʻaʻole ʻoi aku ka maikaʻi o ka lawelawe ʻana o Turing i nā polokalamu shader, akā hiki ke helu pono i ka ray tracing me ka ʻole o nā poloka kūikawā. Ma hope o nā mea a pau, he aha ka mea e hana ai i ka hoʻohana ʻana iā Ray Tracing i mea waiwai nui ʻaʻole wale a ʻaʻole nui ka ʻimi ʻana i nā intersections ma waena o nā kukuna a me nā mea geometry (e hana ʻia e nā cores RT), akā ʻo ka helu ʻana o ke kala ma ke kikowaena intersection (shading). A ma ke ala, pili pono nā mea i helu ʻia o ka hale hoʻolālā Turing i ka GeForce GTX 1660 a me GTX 1660 Ti, ʻoiai ʻaʻole i loaʻa i ka chip TU116 nā cores RT, no laila ʻo nā hoʻāʻo ʻana o kēia mau kāleka wikiō me nā polokalamu ray tracing.
Akā, lawa ka manaʻo, no ka mea, ua hōʻiliʻili mākou i ka ʻikepili e pili ana i ka hana ʻana o "Pascals" (a me ka ʻōpio "Turings") ma ke kahua kaua V, Metro Exodus a me Shadow of the Tomb Raider e pili ana i kā mākou ana ponoʻī. E hoʻomaopopo ʻaʻole hoʻoponopono ka mea hoʻokele a i ʻole nā pāʻani i ka helu o nā kukuna i mea e hōʻemi ai i ka ukana ma nā GPU me ka ʻole o nā cores RT, ʻo ia ka mea e like ke ʻano o nā hopena ma GeForce GTX a me GeForce RTX.

Ma muli o ka ʻoiaʻiʻo ʻo Battlefield V ponoʻī he pāʻani māmā loa (ʻoi loa ma 1080p a me 1440p modes), a hoʻohana ʻo ia i ka ray tracing i nā patches, e hoʻāʻo ana i ka GeForce 10-series me ka koho DXR i hāʻawi i nā hopena hoʻoikaika. Eia nō naʻe, ʻo nā hiʻohiʻona āpau me ke kākoʻo ʻole ʻo Ray Tracing i ka pae silika, pono mākou e kaupalena iā mākou iho i nā hiʻohiʻona GTX 1070/1070 Ti a me GTX 1080/1080 Ti. Hoʻololi pinepine nā pāʻani Electronic Arts me ka kānalua i ka hoʻololi pinepine ʻana i ka hoʻonohonoho ʻana i ka hāmeʻa a kāohi i ka mea hoʻohana no ka manawa hoʻokahi a i ʻole kekahi mau lā.

No laila, e emi ana ka hana o nā kāleka wikiō ma lalo o ka brand GeForce RTX 20 e 28-43% me nā hopena DXR haʻahaʻa a haʻahaʻa, a ma 37-53% me ke kiʻekiʻe a me ka maikaʻi loa.
Inā mākou e kamaʻilio e pili ana i nā hiʻohiʻona kahiko o ka ʻohana GeForce 10, a laila ma ka Low and Medium ray tracing level e nalowale ka pāʻani mai 36 a 42% o FPS, a ma ke ʻano kiʻekiʻe (High and Ultra settings) ua ʻai ʻo DXR i ka 54-67 % o ka huina hoonui. E hoʻomaopopo i ka nui, inā ʻaʻole ka hapa nui, Battlefield V nā hiʻohiʻona pāʻani ʻaʻohe ʻokoʻa ʻike ma waena o nā hoʻonohonoho Haʻahaʻa a me Medium, a i ʻole ma waena o High a me Ultra, ma ke ʻano o ke kiʻi a i ʻole ka hana.
