MIT Graphene Multiplier May Push CPUs to 1,000 GHz
Shane McGlaun / DailyTech
March 24, 2009
‘MIT researchers have devised a graphene signal multiplier that produces a clean signal with low power.’ -
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.

That would be great, and I'm sure MS can find a way to slow it down! LOL

"1024 GHz would be 1 Teraherz, if I am not mistaken. Technically, the increment is 2^10 which is 1024. It usually gets rounded off to 1000 for simplicity."
Use base 2 when dealing with binary representation. Talking about frequency, it's base 10.

Graphene sounds kind of intense, seeing faster processors could be really cool though, this could disprove Moore's law to shame. Heres to hoping

Commentary suggesting that this breakthrough would be best applied to consumer technology is a bit like suggesting that the best use for diamond to strap it to a ring on your bird.

Isn't 1000 GHz 1 teraherz?

hopefully will become available very soon, I would love to have a faster processor.

Hopefully me drooling over the instructions when i get my hands on one of these won't wreck the white papers so I can't read the installation instructions.

hmmm...faster electronics in one part of the formula, and getting them to go faster will produce some faster end results, but the device interconnect is still going to be a fraction of processor bandwidth. As long as there are glass-epoxy boards with metal traces there is going to be an error producing slow down (called bit error rate, the bane of all interface designers). There needs to be a method of interconnect that is on par with the improved device technology.
On the software side general purpose, general function and general application of function dictates bloatware. That's the rule and you will never get away from it. As long as an OS has to be all things to all users it will be fat and excessive. The Mac OS is no different than Windows. It is not a matter of lazy programmers as much as it is an attempt to satisfy lazy users. Most users are not computer literate in the sense of trouble shooting and solving their own problems like we used to be in the leaner and meaner DOS days. You had to be able to write a batch file, confiure config.sys and various .ini or config.txt files yourself. Most users won't ever learn what it takes so the OS has to be able to do it for them and that means a lot of excess code the processor has to slog through. Then there is the curb appeal of an OS and most of the time it is curb appeal that sells insead of function, back to the lazy user thing again. When AppleWorks came with the ability to copy data from one app to another we were all gaga over it., even though the data was static. MS had to one-up it in Office by linking the data in a live state so that changing data in one app changed in the linked app. There is a huge difference in the amount of code between those two data interconnect examples. So the race is on as to how many dazzling features you can bring to market to be the one who makes the sale. Bloat-ware is user driven more than it is lazy programmers. If you want leaner and tighter code in your OS then learn how to use it instead of asking to do the learning for you.
In my opinion we are in amazing times yet at the same time we are in primitive times and graphene is a huge step into the future that we needed yesterday.
