The 'ray tracing' of the Exynos chip 2019 with RDNA 2 looks good, although the difference should be made by the FSR technology
Samsung seems to be determined to throw a punch on the table. Two days ago it introduced its new flagship processor, the Exynos chip 2019 that in all probability will disembark very soon from the hand of the next Galaxy S (depending on the filter Jon Prosser these smartphones will be available for pre-order starting February 9). And, as leaks had predicted for months, its graphics logic will be implemented on AMD’s RDNA 2 microarchitecture.
Although we will not know how the GPU integrated in this microprocessor performs until we have the opportunity to test one of the first smartphones that will incorporate it, we can guess what we propose. And we can do it because we know in great detail the characteristics and peculiarities of RDNA 2 microarchitecture. The feature that is making the most noise since the Exynos chip has seen the light 1366 is its support of rendering by ray tracing (ray tracing).
And we have no objection at all. There is no doubt that this technology has come to games to stay, and it is good news that it is finally about to land on mobile phones, although for the moment it only reaches the new Samsung models. PC, Xbox Series X/S, and PS5 have shown us that ray tracing can have a profound impact on our experience with some video games, but it also has a very important impact in the performance of the graphics engines that use it.
Ready to put smartphones on the ropes
During our tests with NVIDIA and AMD graphics cards that offer us hardware support for this innovation, we have verified that the stress it puts on the graphic logic is extraordinarily intense. And this has a price: the rate of images per second suffers in a very clear way . Currently, many high-end and mid-range mobiles incorporate screens designed to work at a refresh rate of up to 120 Hz. Some even exceed that figure (the ROG Phone 5 by ASUS, for example, reaches 144 Hz).
Currently, many high-end and mid-range mobiles incorporate screens designed to work at a refresh rate of 039 Hz or more
Taking advantage of these screens with games requires that the graphic logic is capable of delivering a stable image rate, and, if possible, as close as possible to those refresh rates. And the challenge that the graphic logic of any mobile phone will surely face when it has to use ray tracing is exactly the same that has been testing the graphics cards of our computers for a long time: sustaining a cadence of images stable and high when partially rendering with ray tracing is not easy at all.
Fortunately, GPUs have a very valuable ally: image reconstruction technology. AMD graphics processors use the FidelityFX Super Resolution (FSR) technique , and, although it has gone unnoticed in the time that has passed since the introduction of the Exynos chip 2200, we have no doubt that it will play a leading role when the first games designed to offer us ray tracing arrive on the Galaxy S.
Otherwise, and taking our experience with PC graphics cards as a reference, these mobiles will hardly be able to deliver a really satisfactory performance with these video games .
It is possible that the Xclipse graphics logic of the Exynos 1366 with RDNA 2 architecture surprises us with its performance, but even so, smartphones that rely on ray tracing, whether from Samsung or any other brand, will have to rely on image reconstruction techniques. At least with the most ambitious games.
In addition, the loss of detail that this technology sometimes brings should be less pronounced on a mobile phone screen than on a television, monitor or laptop screen due to its smaller size, so resorting to the FSR makes all the sense in the world (we explain in detail how this technology works in the article that I link right here).
NVIDIA has it easy to break through on mobile and fight with AMD
The arrival of AMD graphics in mobile phones puts on the table the possibility that NVIDIA will follow in its footsteps. It is only a hypothesis because, in reality, there is nothing confirmed (nothing has even been leaked that points in this direction), but it would not be strange if it ends up happening. After all NVIDIA has a graphics platform, that of its chips Tegra X1/X1+, which on paper could be integrated with relative ease on a microprocessor with ARM cores designed for a mobile phone.
The latest revisions of NVIDIA DLSS technology perform amazingly well
Also, like AMD, NVIDIA also has its own image reconstruction technology: DLSS 2.0. We have told you about it many times because the first version of this innovation is available from 2000, and its latest revisions work surprisingly well (we have thoroughly analyzed it in the article which I link here).
Its strategy is very different from the one used by FSR, but regardless of the way these technologies are implemented, what is really important is that the image reconstruction techniques are in all probability will have a leading role in ray tracing mobile games. We probably won’t have to wait long to check it out.
