The Register has a blip today mentioning that the PowerBook G5 will apparently use HyperTransport. The story that they post is a bit dubious, but they seem fairly convinced that Apple is using HyperTransport in the new PowerBook. This isn’t surprising, because the PowerMac G5 and iMac G5 use HT to tie Apple’s custom northbridge to the rest of the system, but there was no real reason to believe that Apple’s laptops would use the same bus technology as their desktops. Laptops have a lot of special needs, and what works for desktop systems doesn’t always work well on laptops.
Hopefully this suggests that Apple is getting closer to releasing G5-based laptops. Personally, I’m guessing they’ll start to show up around August or September, but that’s a complete guess.
