The computer industry is involved in a never-ending quest for the highest possible performance from computer components and other electrical devices. Over the years, there have been many advances that have boosted the computational power of computer systems from increasing the number of transistors to adding multiple processing cores.

Researchers across the world are hard at work on building microprocessors and other electrical components using a material discovered in 2004 called graphene. A group of researchers at MIT announced on March 19 that new findings made could lead to much faster microprocessors in the future. The new findings could lead to cell phones and other communications equipment that can transmit data much faster than devices available today.

The researchers at MIT have built an experimental frequency multiplier made from graphene. The multiplier is capable of taking an incoming electronic signal at a specific frequency and producing an output signal that it a multiple of the original frequency. One example of a use for the graphene frequency multiplier is inside a microprocessor to determine the clock speed of a CPU.

Frequency multipliers are used widely today according to MIT, but the difference between the multipliers we have today and the graphene multiplier is one of signal noise. Today's multipliers produce noisy signals that require filtration and consume lots of power. The new graphene frequency multiplier consists of a single transistor and produces a clean output signal in a highly efficient manner.

Hopefully CPU's won't be limited below 10Ghz for much longer.

As long as using this does not have any effect on power usage, this sounds like it could be a revolution in CPU engineering.
1. thing this "CPU" is not a x86 cpu
2. i bet there exist today processors which run @ 10ghz (mb look at intel network switch/cpus)
3. worthless news :D

Shove it noob. :D
this news is great as long as the electricity consumed is low
Interesting stuff.

Now they're going to have to work on making a model that the masses can afford :D
better insulator and conductor = better.
Since graphene sheets can be engineered to different conductivities using different rapping coordinate, carbon involvement in future electronic fabrication is definitely desirable.
However, it won't be cheap :p

However, if you wanna pack more transistors, you are really limited to the wire-size.

32nm gate size for example, you need wires around 1nm, and the length of wiring can be kilometers long. The interconnects get more and more tedious as the gate size shrinks, so the clock speed limitation is as simple as most people think.
^^ correct there........carbon is the future.........whether nano tubes or graphene its gonna be all over computing world
Well, seeing as how it's one of the most basic elements...yeah. It's...what...the 4th most abundant element. In solid form, it's also one of the hardest substance known. Think shiny little rocks :)

And no, oxygen is the bodies most abundant element :p Carbon comes after it.
no cells are mostly made up of carbon oxygen gets used up so theres no point arguing with me

Oxygen is constantly replenished.

Have you studied biology like I did? I'm a person who's helped friends study for pre-meds. Unless you show me a degree in biology, you're wrong. Oxygen is the most abundant element in the human body.

That's fact ;)
Why 'only' 1,000Ghz? Is that just a random estimate?
everything has a bandwidth.........
will it be called Thz. hope it do not eat more energy.
Why 'only' 1,000Ghz? Is that just a random estimate?
Probably. This entire idea is still just a theory by the sounds of it. I don't think they actually have a working model yet.
..But how well does it work with PCSX2?
why does everything end up at PCSX2

Wasn't PC developed to do much more
Well, yeah.

But do you realize what kind of forum you're on :p?
forgot that this forum is an emulation forum
