AMD's second-generation RDNA architecture (RDNA 2) was generally praised by reviewers for the performance and power efficiency gains it was able to achieve despite being on the same 7nm node as RDNA. However, this was AMD's first time implementing hardware-accelerated ray tracing (RT), and the results for this, compared to Nvidia's RT capabilities, were far less impressive. That is all set to change according to a report by RedGamingTech (RGT).
The report claims that AMD's RDNA 3 ray tracing performance will get a significant uplift and will be very competitive with what Nvidia offers. It also adds that RDNA 3 will be utilizing a next-gen, "smarter" Ray Tracing IP 2 that could enable it to even leapfrog Nvidia's RT performance. The architecture will also feature new Machine Learning instructions.
AMD hasn't forgotten about the rasterization performance of RDNA 3 either as a leakster on Twitter alleges that Navi 31, Navi 32, and Navi 33 will respectively offer 2.8x, 2.2x, and 1.5x times the performance of AMD's current best, the Radeon RX 6900 XT.
Unknown at this point is how exactly AMD could be achieving this uplift. Whether the performance claims purported here mean the company will be adding more compute units (CUs) to the 80 units on the 6900 XT, or if the improvement is purely based on per CU architectural and clock gains. Or perhaps it's a combination of all of them.
That said, it is important to note that this is all based on speculation and unconfirmed reports for now, so it is advisable to take these rumors with a grain of salt.
