The weighty image: AMD has trailed Nvidia in ray tracing efficiency throughout more than one GPU generations for a number of years. Alternatively, a decent leaker now means that Workforce Purple is i’m ready to re-examine its technique relating to this generation. This knowledge contradicts earlier rumors indicating that the later Radeon lineup would no longer see vital enhancements in ray tracing features.
Famend leaker Kepler_L2 lately remarked that AMD’s later RDNA 4 graphics playing cards will property a “brand new” ray tracing implementation. Occasion this remark doesn’t explicitly circumstance whether or not the imminent merchandise, most probably named Radeon RX 8000, will considerably toughen ray tracing efficiency in comparison to their predecessors, it does counsel a renewed emphasis at the generation.
When puzzled additional, Kepler elaborated that past the RX 7000 GPUs deal with ray tracing in a similar fashion to the RX 6000 form, the RDNA 4’s RT generation seems to be “completely different.”
Ray tracing has been an branch the place contemporary AMD merchandise have significantly lagged in the back of Nvidia’s choices. As an example, our benchmarks divulge that AMD’s flow flagship, the RX 7900 XTX, reviews a considerably better efficiency affect from ray tracing in comparison to Nvidia’s in a similar fashion priced GeForce RTX 4080.
RDNA3 RT was once in accordance with RDNA2 with some enhancements. RDNA4 RT appears totally other.

Prior studies offered a markedly other outlook. Previous this week, assets knowledgeable YouTuber RedGamingTech that RDNA 4 would most effective see a 25 % growth in ray tracing efficiency over RDNA 3. This determine would most probably place AMD’s later playing cards unfavorably in opposition to Nvidia’s imminent Blackwell form and Intel’s Arc Battlemage GPUs relating to ray tracing features. All 3 GPU generations are expected to debut next this week.
One facet the place assets concur is AMD’s resolution to abstain from the flow heavyweight GPU pageant, in lieu targeting extra reasonably priced mid-range choices. Kepler reiterated earlier studies indicating that negative RDNA 4 card will rival the manage two Blackwell GPUs – most probably named the RTX 5090 and 5080.
Contemporary data-mined code means that AMD scrapped a card that doubtlessly may have doubled the efficiency of the 7900 XTX, boasting as much as two times as many chiplets and compute gadgets. In the meantime, the Battlemage form will mark Intel’s inaugural access into the enthusiast-class discrete graphics chip marketplace.
Any other canny construction relating to AMD’s era ray tracing efficiency revolves across the expected specs of Sony’s later PlayStation 5 Professional console.
Rumors counsel that, regardless of being in accordance with RDNA 2 structure, it will deal with ray tracing operations as much as 4 occasions quicker than the bottom PS5. This projection may doubtlessly surpass the ray tracing features of any flow AMD product, together with RDNA 3 GPUs that exceed the console’s value differ. It residue to be perceptible whether or not Sony has proprietary generation at play games or if the mid-generation refresh will incorporate AMD’s untouched inventions.
