james, found something about your last post.
Regardless of what Moore's Law has to say, there's not much point in increasing processor speeds or doubling the bit paths in a CPU if the system bus can't carry the traffic anyway. Since problems with transistors leaking current also worsen as clock speeds increase and CPUs shrink, both AMD and Intel have decided to focus on increasing the number of processor cores on a chip instead of increasing processor speeds.
was in pc world magazine
Yup, your correct, which is why Intel and AMD are looking at other ways other the more cores and why it's more or less physically impossible to mass produce a processor that is greater then 4GHz, leakage and very low yielding processors are among many problems. Read my post more closely, I mentioned making processors more efficient per clock rate rather then increasing the clock speed. A P4 was supposed to be released that had a greater clock speed then 4GHz. Intel abandoned the attempt, their highest remained at 3.8GHz.
More cores are useless unless software developers can utilize them, we are already seeing that the cell processor is to far ahead of its time making it much more difficult and costly to release a game on the PS3 forcing many to abandon the attempt.
We can only shrink the die so much and then we will see AMD and Intel revolutionize the CPU, we will be forced to a new technology such as light, quantum mechanics (long way down the road) among many others.
Overall AMD/Intel shouldn't go after the core race, just like they shouldn't have gone after the MHz/GHz race. But it's whatever investors and the market wants them to do that will drive the company towards their future not what they should do. Whatever renders a company more profitable is what will drive a company to it's future.
When AMD's processors for better then Intel's, AMD failed, why? People thought that the high the clock rate the better the processor, this was of course not the case. Of course there was also serval anti-trust issues that contributed, but thats another story all together. Why does this lead us now? Well people believe the more cores the better, to a point this may be correct, but we are about to watch things get out of control, again. Just you watch as it unfolds over the next year or two. Intel and AMD have already claimed they are not going to start a core war, but they have already announced their future processors which contradicts this statement.....here we go again
Edit: The bit paths are increasing as well, Neleham is a complete redesign of Intel chips in the sense that there will no longer be a FSB, AMD has already elimated this bottleneck.
