what is after ghz? just think, we were running machines with mhz just a few months ago, now we have the ghz's, wow! in 1-2 years my guess is we will be running computers that follow the ghz. stupid post i guess, but i just find it amazing how fast things are moving. i remember the hay days of the commodore 64.

terahertz. Not sure 'bout the spellin tho.

Ya, it's terahertz, the tech is prolly gonna slow down a bit considering (as far as I know) there have been no super advancements in conductive material.

Yup. What he said.

how long do you guys give it? i give it 2 years tops. oh btw, thanks for the answers

I dont know if we will ever reach Terahertz dont you ever think we could discover somthing that is uses a totally different way of transmitting data. It just seems weird that we have gone in a pattern. I think there will just be somthing different to come out.

I give it longer than that. I can't even consider a comp that runs at 1 THz. @ Ghz or 10 GHz, the power alone.

Wonder what hertz the brain runs at. Someone must know.

It varies.

and i doubt its measured in hurtz

Well I don't know enough about how a processor works to try to make a comparison, but I do know a good bt about neurons and brain chemistry. The brain creates pathways that grow and shrink with information. Chemicals start and stop the reactions along these pathways. The pathways themselves use a bit of electricity to relay the signals. So in effect we have a noggin full of switches and circuits, I bet some really smart bored dude/dudette out there has applied that and come up with a hertz number that analogs computers.

both amd and intel have recently developed smaller transistors to help, and overall it will just take time i give it a good 20-25 years before we hit the terahertz mark

I guess that would mean a comp that can think for itself. The human brain isn't even fully or nearly understood how it worx. We get a comp that worx like that, Look out!

first of all we would have to get to 1,000Ghz to = 1Thz

I'm hearing 10Ghz in the next few years, maybe 3-4 years 10Ghz will be there, going at that rate it will take like 50 years, soooooo we will either get there faster, OR we will have a new way

im betting on the new way

i can see quantum computing in 50 years prolly......

but before that we'll have something different then what we are using now for cpu technology, i can figure that much, just don't know what yet....

d'oh

what was i thinking, lol...1-2 years.

if it took 20 years to go from hurtz, mhz, and now ghz, we will see thz in about 10 to 15 years but, thinking on it more, it could even be as far off as 20 years as we need to go 1000 mhz to equal a ghz. But that's just my opinion.

What is quantum computing?

Educate me please.

I belive its atom sized switches and whatnot. Basically itty-bitty computers.

Come Again?


I too would like to be Educated about "Quantum" comps...

I was waaaay off base...lookie here



Quantum Computers
The memory of a classical computer is a string of 0s and 1s, and a classical computer can do calculations on only one set of numbers at once. The memory of a quantum computer is a quantum state which can be in a superposition of many different numbers at once. A classical computer is made up of bits, and a quantum computer is made up of quantum bits, or qubits. A quantum computer can do an arbitrary reversible classical computation on all the numbers simultaneously, and also has some ability to produce interference, constructive or destructive, between various different numbers. By doing a computation on many different numbers at once, then interfering the results to get a single answer, a quantum computer has the potential to be much more powerful than a classical computer of the same size.

The most famous example of the extra power of a quantum computer is Peter Shor's algorithm for factoring large numbers. Factoring is an important problem in cryptography; for instance, the security of RSA public key cryptography depends on factoring being a hard problem. Despite much research, no efficient classical factoring algorithm is known.

Shor actually solved a related problem, the discrete log. Suppose we take a number x to the power r and reduce the answer modulo n (i.e., find the remainder r after dividing xr by n). This is straightforward to calculate. It is much more difficult to find the inverse - given x, n, and y, find r such that xr = y (mod n). For factoring, all we need to do is consider y=1 and find the smallest positive r such that xr = 1 (mod n). Shor's quantum algorithm to do this calculates xr for all r at once. Since xl+r = xl (mod n), this is a periodic function with period r. Then when we take the Fourier transform, we will get something that is peaked at multiples of 1/r. Luckily, there is an efficient quantum algorithm for the Fourier transform, so we can then find r.

There are many proposals for how to build a quantum computer, with more being made all the time. The 0 and 1 of a qubit might be the ground and excited states of an atom in a linear ion trap; they might be polarizations of photons that interact in an optical cavity; they might even be the excess of one nuclear spin state over another in a liquid sample in an NMR machine. As long as there is a way to put the system in a quantum superposition and there is a way to interact multiple qubits, a system can potentially be used as a quantum computer. In order for a system to be a good choice, it is also important that we can do many operations before losing quantum coherence. It may not ultimately be possible to make a quantum computer that can do a useful calculation before decohering, but if we can get the error rate low enough, we can use a quantum error-correcting code to protect the data even when the individual qubits in the computer decohere.

I think after Terahertz, comes Petahertz and then zetahertz. I remember hearing that somewhere.

Mnhtz= my nutz hurt!!!

I don't know but it's alot of power...too much wasted on Office Apps already...we need the next killer app...not more CPU speed!

Well this brain runs at about oh I would say like 300 mhz. It a very slow brain. Can barley use the bathrrom by its self. But it knows all the good porn sites

if anything the tech will speed up, end users will probably not see new technology released as often as we have seen recently in the past 3 years, i would assume that amd and intel will focus on providing new processors that go up in increments of 500 mhz or so, it will save them, and us in the long run, a lot of money to develope new technologies and only put them on the market after a significant speed increase, meaning they wouldn't have to focus on getting one ready while researching another

Well, the current theory in processor mechanics is that the processor speed doubles every 18 months (Moore's law - so named after the co-founder of Intel who coined the law about 40 years ago). So, if we were to follow this law, the fastest computer now is 2 ghz.

Eighteen months from now is 4 GHz.

Three years from now is 8 GHz.

Four and a half years from now is 16 GHz.

Six years from now is 32 GHz.

Seven and a half years from now is 64 GHz.

Nine years from now is 128 MHZ.

Ten and a half years, 256 MHz.

Twelve years is 512 MHZ.

And finally, thirteen and a half years from now (February 2015), we will break the 1 TeraHz mark at 1024 GHz.


Also, as far as minaturization goes, here's a link about a two transistor component made by IBM out of a single carbon molecule.

I don't remember where I read it, but how about 30 gig boxes in 2005. Think about it. The power of a small mainframe in your house. Or in the research facility of an Iraqi group.

I can not see a terahertz any time soon... My guess is we dont get much higher than 25gigahertz for the home user within the next 20 yrs

I think there will be a time not far off where speed will become irrelavent. Kinda like 1Ghz processor just to surf internet and write papers and whatnot, what good is a 300Ghz processor for the same thing?

So I think there will be some sort of limit, of the current computers as we know them today.

The next kind of computer, will be 100x more powerful as our current Gigahertz computers, and will be credit card in size, or possibly a wrist-watch style. Kinda like the computer in StarTrek, you talk, and it does what you want. Holodecks would be an awesome thing to make a reality.

Here's another article about IBM's quantum computer, about a year old.

Pretty soon the home PC will be so fast they'll call it the home MainFrame...lol
