Kinda weird this would be introduced in a laptop, seeing as they don't have a lot of physical space for additional components and they're more bottlenecked by thermals than memory or PCIe bandwidth.

well, it supposes to decrease the number of CPU cycles so it is beneficial to some degree.

The CPU has to decompress, wait, decompress, wait, decompress...compared to the GPU's low latency memory. The GPU can decompress large amounts of data in seconds.

You're right..and at this point, the community should get some beta drivers at the very least for benchmarks, testing, etc. The desktop would be ideal for starting these types of tests as we cannot replace the GPU's is most laptops.

can't have drivers because theres no ratified implementation of the tech yet.

I'm confused why this needs its own title for AMD -- correct me if I'm wrong, but isn't DirectStorage a Windows stack thing? Or is it that Nvidia/AMD have to also implement it in their driver then? If it's something different, will AMD's version of DirectStorage have GPU decompress at launch I wonder. Still seems a odd to me microsoft's won't initially, but perhaps this is just tough to implement on PC, I'm not sure.

the driver needs to implement the streaming decoder for the compressed format.

Well my concern is that AMD want to use GPU decompression with the CPU decompression, which uses Direct Memory Access already. I don't understand some of the design yet, so I'm guessing that research is still being done. The PS5 and Series X (DirectX 12) are already using it, so it's not impossible. It's been done and in use commercially. I do agree that this name may confuse some when abbreviating SAS, because Serial Attached SCSI is the certified name of SAS.

This is actually misinformation, GPU accelerated Directstorage is not even available on the Xbox yet.
