Intel simply throttles its 600MHz chip down to 300MHz. Intel is making a big effort to keep Transmeta down by flooding the sub-notebook market with chip choices. You can either pick a Transmeta Crusoe that's available in three speeds or so and only one model, or pick from 6 different models of Intel mobile chips with three or four speed grades apiece. Having a lot of choices is good if you are looking for an exact fit, but it becomes tedious if there's not much difference among them. I think that reducing electrical power consumption is an important priority for computer manufacturers, especially in light of the nationwide power shortages.
Power consumption is a minmal consideration in a server next to price and performance.
Even more so when you consider that electricity costs show up in a different column from hardware purchases on a balance sheet. I mean, for devices running on batteries, every little bit counts, but for servers there isn't really a driving need to reduce CPU power requirements, and not enought to make an impact on energy demands. It makes more sense for a company to find other areas to reduce power consumption rather then worrying about how much juice their CPU is drawing. If I remember correctly, this is already better than TransMeta. For it certainly is NOT about Transmeta vs. Intel, cuz that would be just stoopid.
