Microsoft needed all the RDNA 2 features, so it started manufacturing the Xbox Series X and S consoles a little later than desired.This was revealed by Phil Spencer in an interview The Verge..
Microsoft started building a new console at the end of the summer, but Sony started earlier and chose not to wait for AMD to complete the design of the new GPU architecture. According to the company, “The Xbox Series X | S is the only next-generation console with full hardware support for all RDNA2 features.”
This includes hardware-accelerated ray tracing, mesh shaders, variable rate shading, and sampler feedback streaming.But AMD both Xbox and PS5 are based on RDNA2. So which feature was the cause of the delay?
Sony has confirmed that the PlayStation 5 does not have variable rate shading. This feature allows the GPU to effectively render different parts of the scene at different resolutions, allowing the GPU to work more in critical areas and less in non-critical areas.You can see more detailed definitions of these terms here..
Sampler feedback streaming also seems to be missing, but this is just a way to optimize bandwidth when textures are loaded from SSD. Microsoft needs this because SSDs on the Xbox are slower than the PlayStation. It seems that the PS5 is equipped with hardware-accelerated ray tracing and mesh shaders.
Interestingly, Microsoft is producing more units of the Premium Xbox Series X than the budget Series S. And so is the first few holiday shopping. However, the product mix will shift to add Series S units in the spring. “In the long run, the price wins most of the time,” says Spencer.
