Last month, NVIDIA announced with fanfare its GeForce RTX Turing graphics cards, and promised to increase realism in future games with the support of ray tracing in real time. We have seen – with great success – how real-time ray tracing can improve shadow, lighting, and water effects in games such as Battlefield V, MechWarrior 5, and Shadow. of the Tomb Raider.
However, real-time ray tracing is extremely expensive for GPU hardware, even with the powerful GeForce RTX 2080 Ti. In a game like Battlefield V, with NVIDIA RTX enabled, the game runs at a little over 60 frames per second at 1080p and between 40 and 50 fps at 1440p (as a pre-release with unfinished GPU drivers). When you set the resolution to 4K, you get less than 30 frames per second with a GeForce RTX 2080 Ti.
With this in mind, it seems that NVIDIA will not support real-time ray tracing on all its next generation GPUs that it will release in the coming months (at least in hardware). Since the GeForce RTX 2080 Ti may need to work with NVIDIA RTX enabled at higher resolutions, performance will be even lower for the RTX 2080 and RTX 2070.
But what about unannounced cards of low end? In her presentation at Citi 2018 Global Technology Conference, Colette Kress, Chief Financial Officer of NVIDIA, made the following statement. "The cards will come out, we'll start with the scorecards," Kress said. "We have the 2080 Ti, the 2080 and the whole of 2070 on the market, which is a big step forward for what people probably did not expect before 10 or 15 years."
Note this key phrase, "Let's start with the ray tracing cards", after which she names the trio of cards announced last month. The wording suggests that only these cards support NVIDIA RTX technology. Given the diminishing returns of real-time ray tracing once you've arrived at the GeForce RTX 2070, it goes without saying that NVIDIA may not want to offer gamers a lower-end experience than low-end hardware. dedicated department. engine tracing equipment on board.
Although it is only speculation at this point, we must remember that we have heard rumors that NVIDIA would launch GeForce GTX 20 Series graphics cards. According to some rumors, the GeForce RTX 2070 would be equipped with a GeForce GTX 2060 (5 GB), also with the Turing architecture. Turing should give the GeForce GTX 2060 a significant performance advantage over the existing GeForce GTX 1060 for OEMs who want to improve the performance of players who do not care about NVIDIA RTX.
Although NVIDIA does not need to fork its Turing GeForce RTX / GTX 20 cards, the company wishing to broadcast the real-time track radius on the game lines as soon as possible, this new generation of cards graphics is simply not up to par. to the task of providing acceptable performance across the entire product line.
