 Thread : Diamond based CPUs? (81Ghz??)

More Information

I realize this is probably an old issue (I read a really old article from 2003) It stated that a CPU made of diamonds could scale to 81Ghz theoretically and run cooler to boot. So what's the deal why don't we make CPUs out of diamonds? Man can manufacture diamonds right. I guess it would still be crazy expensive, that's the one of the reasons that comes to mind. But that doesn't mean that a incredibly microscopic part of the market could use that type of CPU. Code-breaking comes to mind, can never have a CPU that can brute force a code cipher too fast right?

Theorerically a pretty pwerful PC (4 GHz?) need about 80+ years in order to crack a 128bit Encryption (most common in many SSL sites)
a 81GHz processor would need 20 times less which is 4 years. Considering the fact that every month the key in the encryption changes though, I do not think that a 81GHz processor is that much of a threat.
For 64it encryption though, a 81GHz CPU would be a real threat.

If I recall correctly, in U.S. and Canada 128bit encryption is forbidden.
Am I right?

better not be i have some stuff at home that can push 448 bit triple layered( three different algorythems)

I guess 64-bit encryption is pretty easily breakable now if you have a specialist device like an FPGA configured to do it for you. Better yet, get a quantum computer, which I'd like to bet certain government agencies have breaking codes right now :wink:

As for why not make CPU's with diamonds, I'd imagine it would be a pretty expensive thing to make, much more so than silicon based CPUs.

Man made diamonds have the same properties as natural ones and they are alot cheaper.

If I remember right, back when I used to contribute to distributed computing for cracking RSA 128 bit it was ILLEGAL to EXPORT the 128bit technology, not Illegal to use in the USA.

Ah, I wasn't aware of that.

Maybe it will happen someday, but it would probably be very costly to retool to use them now. The big CPU makers don't like to take risks when they don't need to, so I'll bet they will push Silicon for all it's worth, until they have no other choice but to change material.

I don't think it really compares to the 1 THz+ speeds BDT processors could deliver, for probably a lot less... wonder if you could combine the two ideas?

Chemically, a diamond is just a very large clump of Carbon molecules. Carbon is highy abundant in the universe, and on earth.

See this wiki picture.

At any rate, Carbon nano tubes share a lot of the same properties as diamonds, however they are easier to manufacture and manage. I'd say that the diamond processor will evolve to the CNT processor. You'll likely see CNT semiconductors first appear in some sort of flash-RAM.

I understand how a cpu utlizes Silicone with all of its transistors and such, but Diamonds? How is that even possible>??
Besides that would one hell of an expensive CPU
:lol:

Perhaps in a couple of years once technology really kicks off, enthusiasts might be able to OC at those speeds. Do you have like a diphagram or sum kind of link thats explains how that 81 Ghz cpu is constructed and how it works??
Im just really fasinated on this topic.

My ass does all my talking!

Believe it or not, natural diamonds are one of the more abundant precious stones available. It's just that the prices or diamonds are kept in check by the diamond cartels and jewelry industry as they work to keep availability low and jack up the price. In reality, natural rubies and emeralds command a much higher price to compared to a diamond of the same carat weight. Industrial diamonds are actually reasonably priced, compared; but I don't know if the quality (industrial vs d color flawless) of the diamond would make a difference for a cpu. So, even though synthetic diamonds are chemically the same a natural diamonds, I also wonder if there is something inherent in the process that would make them less desireable for a cpu.

Julian33 has it right, silicon is the 2nd most available conductive element on earth right after oxygen.

True, but there are distributed solutions for this, for example you can use a few thousand networked computers or a supercomputer with a few thousand processors. I expect that certain government agencies in some countries have already solved the problem using plain silicon. Here's an even simpler solution: get 256 computers, each of them is assigned an ASCII code and tries passwords starting with that code. You don't even need a network, just a little planning...

Yeah the diamond industry is f'ed up.

Most scientists agree that when nano-technology really leaps foward, diamonds will be the first objects synthetically produced through nano-manufacturing, because they are the simplest compound.

In fact, there have even been a few fiction books (one prominent; the name eludes me now tho) that try and illustrate what a diamond-manufactured woprld would be like (Windows made of diamonds, etc).

At any rate, a lot of compounds can be manipulated to become semi-conductors, but silicon has special properties that make it a great candidate. An electric charge is nothing more than electrons moving across atoms, and it's not hard to encourage that through chemistry with normally non-conductive elements.

Industrial diamonds can already be produced by IBM.

Yeah they've been around for a while. it's a good example of how badly De Beers has the industry by the nutz.

Don't think so. I've used 128 bit encryption for years here in the US.

Does the diamond processor use light or electricity?
Optic processors that use light are in the works and those obviously have the potential for ridiculous speeds as light can move so much more faster than electrons.

Don't know if they would use light or electricity, though carbon is a good electrical transmiter and since diamonds are merely very compressed carbon, they could use electricty. Beyond that, I haven't the faintest idea.

I found this thread on another forum:

http://www.physicsforums.com/archive/index.php/t-7525.html

And here's what I read last night:

http://www.geek.com/news/geeknews/2003Aug/gee20030827021485.htm

Basically what I got for limitations are a manufacturing process that takes quite a while, De Beers threatening the companies that would produce the superior quality diamonds at lower (much lower!) prices, and heat dissipation. It's very interesting I wouldn't be surprised if in the next 20 years or so we have some of these in the making 8O

It said they actually had a working model, too!
