About this siteFor six years, the Internet Nexus served as my technology blog, but I've since started blogging at the SuperSite Blog instead. If you're looking for the blog, please head there. --Paul Wednesday, September 10, 20032 GHz G5 often runs at 1.3 GHzSo when is the world's fastest computer not the world's fastest computer? When it's a Power Mac G5, apparently: According to a WWDC conference video that came with the student Apple Developer Connection ("Power Macintosh G5 Architechural Overview"), the 2 GHz G5 processor scales down to just 1.3 GHz when it's running too hot or when it's being underutilized. On the PC side, we only see this kind of technical chicanery with notebooks, where it actually make sense to scale back performance in order to get better battery life. But why would you need to do it on a desktop machine that's always plugged in? It's because the G5 runs way hot, too hot for normal cooling techniques (thus the "innovative" cooling design Apple was forced to come up with). This makes the "world's fastest computer" claims even more spurious. It even makes claims that it's a PC at all spurious. This thing is a big, fat, honking workstation. And a hot one at that.
