Ukuqala namhlanje, umkhondo we-ray wexesha lokwenyani awuxhaswanga kuphela ngamakhadi emizobo ye-GeForce RTX, kodwa nangokukhetha amakhadi emifanekiso yeGeForce GTX 16xx kunye ne-10xx. Umqhubi weGeForce Game Ready 425.31 WHQL, obonelela ngamakhadi evidiyo ngalo msebenzi, unokukhutshelwa kwiwebhusayithi esemthethweni ye-NVIDIA okanye ihlaziywe ngeGeForce Ngoku isicelo.
Uluhlu lwamakhadi evidiyo axhasa umkhondo we-ray wexesha lokwenyani lubandakanya iGeForce GTX 1660 Ti kunye neGTX 1660, Titan Xp kunye neTitan X (Pascal), iGeForce GTX 1080 Ti kunye neGTX 1080, iGeForce GTX 1070 Ti kunye neGTX 1070, kunye ne Inguqulo ye-GeForce GTX 1060 ene-6 GB yememori. Ewe kunjalo, ukulandelela imitha apha kuya kusebenza kunye nemida ethile xa kuthelekiswa namakhadi emizobo yeGeForce RTX. Kwaye incinci ikhadi levidiyo, izithintelo ezinamandla ziya kuba. Nangona kunjalo, inyani yokuba abanini be-GeForce GTX 1060 engenamandla kangako baya kukwazi "ukuchukumisa" itekhnoloji entsha abanakukwazi ukuvuya.
Ngelixa amakhadi evidiyo eGeForce RTX aneeyunithi ezikhethekileyo zekhompyuter (RT cores) ezibonelela ngokukhawuleziswa kwehardware yokulandela umkhondo weray, amakhadi evidiyo eGeForce GTX akanazo izinto ezinjalo. Ke ngoko, ukulandelwa kwemitha kuphunyezwa kuzo ngolwandiso lwe-DXR lwe-Direct3D 12, kwaye ukusetyenzwa kwe-ray kuya kusingathwa zii-shader eziqhelekileyo zokubala kuluhlu lwee-cores ze-CUDA.
Le ndlela, ngokuqinisekileyo, ayiyi kuvumela amakhadi evidiyo asekelwe kwi-Pascal kunye ne-Turing GPUs ephantsi ukubonelela ngenqanaba elifanayo lokulandela umkhondo we-ray njengoko iimodeli ze-GeForce RTX zikwazi ukwenza. Izilayidi ezipapashwe yi-NVIDIA ngeziphumo zokuvavanya ukusebenza kwamakhadi evidiyo ahlukeneyo usebenzisa umkhondo we-ray ubonisa umahluko omkhulu phakathi kweemodeli zeGeForce RTX kunye neGeForce GTX.
Ngokomzekelo, kumdlalo we-Metro Eksodus, apho ukukhanya kwehlabathi kubonelelwa ngokusebenzisa umkhondo, akukho nanye yekhadi levidiyo ye-GeForce GTX yakwazi ukubonelela nge-FPS eyamkelekileyo. Nokuba i-flagship yesizukulwana sangaphambili, iGeForce GTX 1080 Ti, yakwazi ukubonisa kuphela i-16,4 fps. Kodwa kwi-Battlefield V, apho ukulandelela kuphela kunika izibonakaliso, i-flagship yesizukulwana sePascal yayisakwazi ukufikelela kwi-30 FPS.
Nangona kunjalo, i-NVIDIA ivavanye amakhadi evidiyo kwezona zicwangciso ziphezulu zemizobo, ezinobuninzi bokulandela umkhondo kunye nesisombululo seepikseli ezingama-2560 Γ 1440. Oko kukuthi, iimeko, ukuyibeka ngobumnene, yayingeyona ilungileyo: iGeForce GTX 2060 efanayo kwi-Metro Eksodus i-avareji encinci ngaphezu kwe-34 fps. Kuya kwenzeka ukufezekisa i-FPS "edlalwayo" kumakhadi evidiyo amadala ngokuthoba isisombululo kunye nomgangatho wegraphic. Kodwa okokuqala, ukusebenza kwabo kuya kuchatshazelwa luseto lwe-ray tracing intensitety.
Masikukhumbuze ukuba okwangoku unokuqhelana ne-ray tracing kwimidlalo emithathu: I-Battlefield V, i-Metro Eksodus kunye ne-Shadow ye-Tomb Raider. Ikwafumaneka kwiidemos ezintathu: Intliziyo ye-Atomic, Ubulungisa kunye nokucamngca. Zombini kwimidlalo nakwidemos sinikwa iindlela ezahlukeneyo zokusebenzisa umkhondo weray. Kwenye indawo inoxanduva lokubonakaliswa kunye nezithunzi, kwaye kwenye indawo inoxanduva lokukhanya kwehlabathi.
