8 Ghz P4???

that's nothing.

anyone read that article on here last week about the 500ghz room temperature processor created by IBM?

They froze the processor to absolute zero, and apparently it creates some sort of chemical change that allows the processor to handle extremely high temperatures at room temperature.

LOL WTF
 
cromwell already corrected me

it was a misleading article that falsely represented some sort of analog packet switching transistor created by IBM as a new processor of some sort
 
yea it would take something like -700C to become close to freezing the molecules into place because absolute zero is impossible in the view that molecules cannot be stopped from moving
 
you cant put anything to absolute zero

the closest they got was .6 from 0K and there they had tiny rubidium atoms and used lasers to push them together so tight that they wouldn't move, since temperature is just energy and energy is only created when things move. so molecules rate of speed is temperature, hence the reason you cant go below absolute zero

Though 0.6 K is cold, it is orders of magnitude from the coldest. The coldest is on the order of 100 pK, and dilution refrigerators alone can reach the micro-K range.

Do you know how many pipeline stages a C2D has? 14. The purpose of having a stupidly long pipeline is that you can move through each stage fast enabling you to ramp clock speed through the roof. If it takes 10ns to do the slowest step that determines your clock speed cap.

Jet do you have a link for the 5GHz C2D? That's probably getting close to the max speed of a C2D.

the C2D or C2Q has a 12 stage pipeline

No, the Core architecture has a 14-stage pipeline, however the Pentium M has a 12.

So many of the articles about that transistor were misleading and then they were combined with a horde of people making comments like 'soon we can have 500GHz CPUs!!!!'
 
500GHz CPU? Maybe, I don't know. 500GHz anything though, we already do it is a transisitor developed in part by IBM that switched at 500GHz :P
 
the trouble with overclocking it to 8GHz is that its life will be severley reduced, he probably has it being cooled by liquid nitrogen capsles
 
Probably, and the electron migration will be nuts. But they aren't doing it for long processor life :)

When people overclock it to say, 8Ghz, its only for a very short time, maybe long enough to boot, run cpu-z, and run SuperPi. It would be way too costly and time consuming to try and actually keep it at 8Ghz.
 
I believe that Intel had actually created the Netburst architecture to give them the ability to eventually run 4-5Ghz speeds factory, but of course we all know the [relative] failure of the netburst architecture in relation to heat and EM. I saw an article on this subject somewhere, but that was a reinstall or two ago. I should really save links on my flash drive...

The rate of advancement and innovation is insane today. Multiplicity of cores will likely keep speed from being a driving factor [again]. Heat is just such an issue.

Interesting read of an article, though!
 
The second incarnation of netburst (northwood core) could go well past 5GHz and prescott got no where near the frequency limit of the pipeline. Netburst was quite happy clocking high, it just wanted a lot of power to do it.
