The back of my envelope says that if a 50Wh laptop battery gave you 5 hours of run time, an average of 10W, then reducing that to 7W whilst keeping everything else the same would give you just over 7 hours. But it likely wont be quite that much in practice because all the components are constantly changing their power requirements and my envelope has a corner torn off at that point.
I don’t have experience with laptop PCI-E 5.0 SSDs, but I don’t think the desktop power consumption numbers (dynamic?) would map directly to laptop use cases. I.e. I highly doubt laptop PCI-E 5.0 SSDs consistently eat 5-10 watts during runtime. There would have to be some sort of power focused optimization routines. With desktops, you don’t really need this.
I think the bigger goal is lowering power impact from PCI-E 5.0 SSDs on a relative basis. The focus seems to be on significant improvements in power consumption for relatively modest decrease in top speed capabilities; a trade-off that one could argue is a perfect fit for laptops.
