![]() RTX runs on Nvidia Volta-, Turing-, Ampere- and Ada Lovelace-based GPUs, specifically utilizing the Tensor cores (and new RT cores on Turing and successors) on the architectures for ray-tracing acceleration. RTX facilitates a new development in computer graphics of generating interactive images that react to lighting, shadows and reflections. Historically, ray tracing had been reserved to non- real time applications (like CGI in visual effects for movies and in photorealistic renderings), with video games having to rely on direct lighting and precalculated indirect contribution for their rendering. Nvidia RTX enables real-time ray tracing. Nvidia RTX (Ray Tracing Texel eXtreme also known as Nvidia GeForce RTX under the GeForce brand) is a professional visual computing platform created by Nvidia, primarily used in workstations for designing complex large-scale models in architecture and product design, scientific visualization, energy exploration, and film and video production, as well as being used in mainstream PCs for gaming. ![]() However, this feature is only available in Reflex-supported games.īesides, while it may not fully match the performance and visual quality of a real RTX 4080 GPU, the far lower power consumption of GeForce NOW could lead to significant money savings over extended periods, particularly in the current energy crisis.An aftermarket variant of the RTX 2080 made by MSI Owners of G-SYNC and G-SYNC compatible displays can even take advantage of the technology to dynamically vary the streaming rate to match the display's refresh rate, further driving down latency. ![]() While playing via cloud will hardly be feasible for any competitive eSports player, there's a new 1080p/240 FPS option to minimize latency as much as possible. This could partly account for the lower performance.Įven with all these caveats, the upgraded GeForce NOW Ultimate tier offers the best cloud experience available anywhere with its support for 4K/120 FPS (on PC and Mac apps), HDR displays, and Ultrawide displays. The author also estimates that each GeForce NOW Ultimate cloud instance receives around 70-72 shader multiprocessors, a bit less than the 76 of the real RTX 4080. The L40 is equipped with 48 GB of GDDR6 VRAM, though since each data center GPU actually serves two cloud instances, each instance gets 24 GB of VRAM (as listed in the benchmarks). As for the GPU, the website's best guess is that NVIDIA is using the L40 data center GPU, which is based on Ada Lovelace's architecture just like the consumer-oriented RTX 4080. Hardware-wise, the benchmark pointed to an AMD Ryzen 16-core CPU with 28 GB of central RAM. In this test, the GeForce NOW Ultimate tier somehow beat the actual RTX 4080, albeit only slightly (137 average FPS vs. Lastly, Crystal Dynamics' Shadow of the Tomb Raider painted a similar picture, except for the 4K resolution. If they used the same graphics preset (Very High), the 1080p benchmark should have scored much higher than 1440p's. At 1080p, the real RTX 4080 scored 157 average FPS, 46.7% higher than GFN Ultimate's 107 FPS at 1440p, the difference mentioned in the website's slide is even starker at 80.5%, though we have to question the result of 195 average FPS recorded for the RTX 4080. HardwareLuxx also tested Eidos Montréal's Marvel's Guardians of the Galaxy which, for some reason, didn't allow 4K resolution to be selected (even though GeForce NOW has supported 4K resolution for a long time). At 1080p, GFN Ultimate scored 92.8 average FPS, whereas the bona fide GPU ran 53.6% faster at 142.6 FPS at 1440p, the cloud test registered 78.1 average FPS, while a physical PC ran 37.1% faster at 107.1 FPS at 4K, GFN Ultimate registered a similar difference (38.1%), with the actual RTX 4080 coming out on top with 52.1 average FPS against the cloud's 37.7 average FPS. ![]() For example, in CD Projekt RED's Cyberpunk 2077, the GeForce NOW Ultimate tier trailed considerably behind a real RTX 4080. ![]()
