PS5 new compression technology makes SSD even faster


PS5 new compression technology makes SSD even faster

The PlayStation 5 differs from the Xbox Series X anyway with a faster SSD and storage architecture. A technology now data compression licensed by Sony could further reduce loading time. And in abundance.


The PS5 SSD can carry data at a speed of 5.5 GB per second. With the help of data compression, this value improves when transferring to graphics memory to 8-9 GB per second, which corresponds to a compression ratio of 1.5: 1. This was already known. A Kraken process called “Oodle Textures” now optimizes the value up to 3: 1, as explained by the developer of cbloom (via PCGH). That would be up to 16.5 GB, which the PS5 could move per second.

Games can use less storage space

When Sony announced the value of 8-9 GB per second, the company had not yet licensed Oodle Texture technology. Sony has now offset this for all games PS4 and PS5. As the textures are compressed losslessly, the player will not notice anything, the quality remains the same. The potential benefits: Games can be downloaded faster, more games fit on the SSD, and game load times are shorter. After all, textures take up the majority of storage space in modern games, and the PS5 SSD is only 825 gigabytes in size.

5.5 Gb / s becomes 16.5 Gb / s

With the new technology, the texture data first arrives in the Kraken decoder with Oodle Texture at an SSD speed of 5.5 GB / s, and then into the graphics memory up to 16.5 GB / s. It remains to be seen how the PS5 fast storage architecture will work in practice. It could be that the benefit of better load times is largely limited to exclusive titles, as developer “Ori” believes.
