From this source it emerges that the data bandwidth for the PS5 HDMI 2.1 is limited to 32 Gbps, while the maximum achievable is 48 Gbps. As explained in the video: “We analyzed the HDMI 2.1 output on the Sony PS5 (Playstation 5) console and found that the maximum bandwidth it can deliver at 4K at 60Hz or 4K at 120Hz is 32Gbps, which is lower than the Xbox Series X band that reaches 40 Gbps ".
HDTVTest is a YouTube channel to be considered reliable, as it had already communicated in the past that the Xbox Series X Blu-ray player does not support Dolby Vision, HDR10 + and True Black and he was not wrong. In this sense, the performance of the Xbox Series X is much more in line with the standards for the amount of data received by current TVs that support HDMI 2.1. HDTVTest also specifies that 32 GBps inevitably run into limitations, as 10-bit HDR values in 4: 4: 4 with maximum color sampling are not possible on PS5, which does not reach the required 40 Gbps.
At the moment, there are few contents that can be viewed in 4K at 120 Hz with 10-bit HDR, but this limitation should still be noted. According to some, a remedy could be found with a software update, but it still has to be proven. The never ending story and a thousand doubts that revolve around the PS5 HDMI 2.1 will certainly have implications, we will keep you updated.
