E hoʻomaka ana i kēia lā, kākoʻo ʻia ka nānā ʻana i ka ray manawa maoli e nā kāleka kiʻi kiʻi ʻo GeForce RTX, akā ma ke koho ʻana i nā kāleka kiʻi GeForce GTX 16xx a me 10xx. ʻO ka mea hoʻokele GeForce Game Ready 425.31 WHQL, nāna e hāʻawi i nā kāleka wikiō me kēia hana, hiki ke hoʻoiho ʻia mai ka pūnaewele NVIDIA mana a i ʻole e hoʻonui ʻia ma o ka noi GeForce Now.
ʻO ka papa inoa o nā kāleka wikiō e kākoʻo ana i ka nānā ʻana i ka ray manawa maoli ʻo GeForce GTX 1660 Ti a me GTX 1660, Titan Xp a me Titan X (Pascal), GeForce GTX 1080 Ti a me GTX 1080, GeForce GTX 1070 Ti a me GTX 1070, a me ka ʻO ka mana GeForce GTX 1060 me 6 GB o ka hoʻomanaʻo. ʻOiaʻiʻo, e hana ka ray tracing ma aneʻi me kekahi mau palena i hoʻohālikelike ʻia i nā kāleka kiʻi kiʻi GeForce RTX. A ʻo ka ʻōpio o ke kāleka wikiō, ʻoi aku ka ikaika o nā kaohi. Eia naʻe, hiki i nā mea nona ka GeForce GTX 1060 ikaika ʻole ke "hoʻopā" i ka ʻenehana hou ʻaʻole hiki ke hauʻoli.
ʻOiai ua loaʻa i nā kāleka wikiō GeForce RTX nā ʻāpana hoʻopili kūikawā (RT cores) e hāʻawi i ka wikiwiki o ka lako no ka huli ʻana i nā hihi, ʻaʻole loaʻa nā kāleka wikiō GeForce GTX i kēlā mau mea. No laila, hoʻokō ʻia ka ʻimi hihi i loko o lākou ma o ka hoʻonui DXR no Direct3D 12, a e mālama ʻia ka hoʻoili ʻana i nā kukui e nā mea hoʻonaninani helu maʻamau ma kahi ʻano o nā cores CUDA.
ʻO kēia ala, ʻoiaʻiʻo, ʻaʻole e ʻae i nā kāleka wikiō e pili ana iā Pascal a me nā Turing GPU haʻahaʻa e hāʻawi i ka pae like o ka hana hihihihi e like me ka hiki i nā hiʻohiʻona ʻo GeForce RTX. Nā kiʻi paʻi ʻia e NVIDIA me nā hopena o ka hoʻāʻo ʻana i ka hana o nā kāleka wikiō like ʻole me ka hoʻohana ʻana i ka ray tracing e hōʻike i ka ʻokoʻa nui ma waena o nā hiʻohiʻona GeForce RTX a me GeForce GTX.
No ka laʻana, i ka pāʻani Metro Exodus, kahi i hāʻawi ʻia ai ka hoʻomālamalama honua me ka hoʻohana ʻana i ka tracing, ʻaʻohe o nā kāleka wikiō GeForce GTX i hiki ke hāʻawi i ka FPS ʻae. ʻO ka hae hae o ka hanauna i hala, ʻo GeForce GTX 1080 Ti, hiki ke hōʻike i 16,4 fps wale nō. Akā ma ke kahua kaua V, kahi e hāʻawi ai ka ʻimi ʻana i nā noʻonoʻo wale nō, hiki i ka hae o ka hanauna Pascal ke hiki i 30 FPS.
Eia naʻe, ua hoʻāʻo ʻo NVIDIA i nā kāleka wikiō ma nā hoʻonohonoho kiʻi kiʻi kiʻekiʻe loa, me ka ʻoi loa o ka ray tracing intensity a ma kahi hoʻonā o 2560 × 1440 pixels. ʻO ia hoʻi, ʻo nā kūlana, e waiho mālie, ʻaʻole i ʻoi aku ka maikaʻi: ʻo ka GeForce GTX 2060 ma Metro Exodus i ʻoi aku ka liʻiliʻi ma mua o 34 fps. Hiki ke hoʻokō i ka FPS "pāʻani" ma nā kāleka wikiō kahiko ma ka hoʻohaʻahaʻa ʻana i ka hoʻonā a me ka maikaʻi kiʻi. Akā ʻo ka mea mua, e hoʻopili ʻia kā lākou hana e nā hoʻonohonoho hoʻonohonoho hoʻonohonoho ray tracing intensity.
E hoʻomanaʻo mākou iā ʻoe i kēia manawa hiki iā ʻoe ke kamaʻāina me ka ray tracing i ʻekolu pāʻani: Battlefield V, Metro Exodus a me Shadow of the Tomb Raider. Loaʻa iā ia i ʻekolu demos: Atomic Heart, Justice and Reflections. Ma nā pāʻani a me nā demos ua hōʻike ʻia mākou me nā koho like ʻole no ka hoʻohana ʻana i ka ray tracing. Aia ma kekahi wahi ke kuleana no ka noʻonoʻo ʻana a me nā aka, a ma kahi ʻē aʻe ke kuleana no ka hoʻomālamalama honua.
