Ray tracing technology has been greeted by video game fans with much skepticism and humor. Despite relatively cold adoption, Ray Tracing is present in more and more games. AMD also offers support for this technology with cores Ray acceleratorswhich would have been redesigned for the RX 8000 Series of the RDNA4 architecture.
The big problem of Laser trace lies in the high computational cost. The amount of FPS obtainable with this technology is reduced by almost 50%. Resizing technologies have therefore been developed to compensate for a large part of these losses.
Redesigned ray accelerators
Nvidia for ray tracing technology has included in its graphics cards the so-called Hearts RT.
You should know that AMD’s solution is, so to speak, “improvised”. They have followed NVIDIA in this regard and are still working on improving these types of cores. The problem is that Ray Tracing at AMD still depends a lot on Stream Processors, the other type of core in the company’s GPUs.
RDNA2 (RX 6000 series) were the company’s first GPUs with dedicated light tracing cores compatible with DirecX 12 Ultimate. RDNA 3 (RX 7000 Series) achieves a 50% performance improvement compared to the first version of this core type. A very good evolution of the Ray Accelerators, but much more is needed to be able to compare to NVIDIA’s RT Cores.
According to information disclosed by “Kepler L2”, the new GPUs of RDNA4 architecture (RX 8000 Series) will have completely redesigned ray accelerators. The idea would be that these cores already bear a large part of the weight of Ray Tracing tasks, thus offloading the Stream Processors. Something that will enhance the gaming experience with ray tracing technology.
Complementing the ray accelerators we have AMD FSR. This is the company’s scaling technology to compensate for performance losses experienced with ray tracing.
@Kaizar24 RDNA3 RT was based on RDNA2 with some improvements. RDNA4 RT is completely different.

Launch of the new RX 8000 series
We currently do not have a date for the launch of these new graphics cards. They will surely arrive by the end of the year, seeking to directly compete with the NVIDIA graphics that will be presented at the same time.
Before then we could have a sneak peek, since the company will be present at Computex which will be held early next month. During AMD Keynote, the presentation of the Zen5 architecture which will bring to life the Ryzen 8000 series as well as the next generation of EPYC processors for servers and Data Centers is expected.
The question remains whether AMD will give an idea of RDNA4, although we hope so. The rumors we know about the company’s upcoming graphics make us think it will be a great product. It has to be, since the RTX 50 Series aims to be a true monstrosity for video game enthusiasts.
