AMD CFO David Kumar has confirmed that the RDNA 2 architecture will debut on PC first, very positive news, as it means that the first graphics cards based on that architecture will be available before PS5 and Xbox Series X launch.

We do not have a specific launch date, but considering that both consoles will arrive between november and december We can make it clear that it is most likely that the presentation of the new AMD graphics cards based on the RDNA 2 architecture will take place between September and October.

David Wang, vice president of the Radeon Group, said at the time that the RDNA 2 architecture will serve to shape a complete catalog of graphics cards, information that Kumar has ratified and that has very important implications. Until now AMD had limited the launch of its new graphics cards to very specific ranges, had omitted certain levels for long periods of time and had adopted a strategy that prevented it from effectively covering the entire general consumer market and competing at the same level with NVIDIA.

Well, with the RDNA 2 architecture that will change. AMD is going to launch a set of new graphics cards based on this architecture with which It will cover both the low-end and mid-range, as well as the high-end.

AMD RDNA 2: ray tracing, higher IPC, and improved efficiency

The RDNA 2 architecture has generated a lot of expectation for three great reasons. The first is the most obvious, the fact that it was the one chosen to empower the new generation of consoles It has given him a leading role in the media, but it has not been his only merit to deserve our attention.

This new architecture will be the first from AMD to have hardware ray tracing acceleration. It is still unclear how the Sunnyvale company plans to introduce such acceleration, but some leaked patents pointed to a system supported by both texture units and shaders. If this is confirmed, the difference in power between Xbox Series X and PS5 could be enormous, since the former will have more computing units, and therefore it will also have more shaders, more texture units and more raster units.

Finally we also have the question of performance and efficiency improvement that AMD will achieve with RDNA 2. In addition to the improvement in the IPC level compared to RDNA, we find a significant increase in computing units, with a rise in frequencies and with a significant improvement in efficiency (less consumption, lower working temperatures ).

Rumor has it that AMD’s top of the range, the Radeon RX 6900 XT, a provisional name that has not yet been confirmed, will have 80 CUs, which leaves us with a total of 5,120 shaders, 320 texturing units and 96 raster units. Its memory bus could be 320 bits, and would be accompanied by up to 16 GB of 16 GHz GDDR6 memory.

With those specifications you would have no problem outperform the RTX 2080 Ti by a wide margin from NVIDIA, we already had the opportunity to talk about this issue at the time, but I am not sure that it will be able to compete with the future RTX 3080 Ti from NVIDIA. Another important issue to consider, in this regard, is the performance of RDNA 2 in ray tracing, something that, at the moment, is a mystery.

Before finishing I remind you that the CFD of AMD has confirmed that the company also plans introduce Zen 3 architecture before the end of 2020. This architecture will be used in Ryzen 4000 processors.
