The head of AMD Lisa Su at the opening of Computex 2019 clearly did not want to focus on the new gaming video cards of the Radeon RX 5700 family with the Navi architecture (RDNA), but published next on the company's website brought some clarity in particular to the new graphic solutions. When Lisa Su demonstrated a 7nm Navi GPU on stage, the monolithic die without adjacent HBM2 memory chips immediately prompted the idea of ββββusing GDDR6 memory, which rival NVIDIA adopted last year, introducing graphics solutions of the family Turing.
First, AMD's use of GDDR6 memory was reported by the website editor Ryan Smith on his Twitter page, later references to this type of memory were also found in a press release on the company's website. In addition, AMD emphasized that the RDNA architecture will form the basis not only for gaming graphics cards, but also solutions for broadcasting games from the cloud, as well as new game consoles. During her speech, Lisa Su stated that RDNA will be AMD's current graphics architecture for the next decade.
There are also official confirmations GPU execution units that the new RDNA architecture has brought. AMD itself has not yet announced the details of these changes, but reports that RDNA gives a 25% increase in performance per clock compared to GCN, and the performance-to-power ratio has improved by 50%. By the way, the company is not going to write off the GCN architecture, it will still serve it in the computing acceleration segment.
At a press conference after his speech, as the resource clarifies , Lisa Su confirmed her intentions to talk about plans to implement ray tracing in games at the E3 2019 event, which will be livestreamed on June XNUMXth. Since the response of the head of AMD implied a story about plans for the future in the graphics segment, it can be assumed that the first generation of Navi will not receive ray tracing support at the hardware level - at least in the desktop graphics segment.
