Makes you wonder why they did not just pop a couple of Tualatins on a chip, instead of Pentium 4s. Tualatins are still better than anything AMD or Intel have for that, since they run so much cooler they would not have to be throttled back artificially like the Athlon 64 and Pentium 4.
Also, Intel never planned on going dual core for a good reason, it is a lousy design either way; being just a poor man's dual processor system. Instead, they designed the Itanium which focused more on instruction level parallelism instead of thread level parallelism. Obviously, the former is better since it works for every application ever written, whereas for applications where multithreading is poorly suited, multi-core systems run poorly since they are done so badly they run at lower clock speeds. Since the Itanium is a market failure, at least in the mainstream arena, Intel is forced to wring out more performance from the miserable x86 instruction set and naturally were caught flat footed since they never wanted to go this way.
I am amazed at how well AMD and Intel have made people believe dual cores are a good thing. It is an egregious lie; it really means they have no clue how to develop processors from here on. AMD gave up much earlier, and at least realized they had no clue. Intel thought they did and jacked up the transistor count for the Prescott with all these new wonderful features, and fell on their faces because of power problems. So now they figured out what to do, add something very few people need, and those that do need them would do better with a real multiprocessor system.
I wonder how much money is wasted on too powerful PCs, in terms of electricity every year. When you factor in how many people do mainly surfing the internet, or playing MPEGs or similarly simple things like this, and are using 75 watt processors to do this. Multiply it by the millions and millions that have these machines, and it has to be a huge amount of money that is wasted every year. Now these bozos crank it up even more with dual processors when virtually no one even needed the highest speed single processor. And, of course, if they did need a dual processor, or more, configuration, they should get a real one instead of some half-rate dual core system with a shared memory bus and lower clock speeds.
Still, this is a good thing somehow. Good grief.
