Hamburg researchers build logic block of atoms-clock speeds are possible up to 10,000 GHz

Hi!
I found an article on a german Computer-site about a new developed Technology by the Institute of Applied Physics, Hamburg University in Germany.
The original story is in German language and it would take me to long for a complete translation so
i used the Google Translation-Tools.

Only a few days ago, Intel released the 22-nanometer process and a new transistor design for next generation processors (Ivy Bridge) before. The reduction of semiconductor structures in computer chips, but inevitably encounter at some point of their physical limitations, so that alternatives are needed. One of the potential candidates for future computer chips and storage devices is spintronics , a branch of nanoelectronics. In contrast to today's semiconductor technology is in charge of spintronics not only the use of electrons, but also its spin

But the Craziest is this statement:
Also another problem of the current semiconductor technology, with increasing clock frequencies by increasing the charge transport waste heat, can be circumvented in spintronics, since no cargo is transported. This clock speeds are possible up to 10,000 GHz,

This has got to be a fast processor!!! You'll be able to attain what, 30 000FPS in games?

Let's just hope that the OS won't be 3000gigs then, since they tend to grow as the parts are improved, roughly giving you the same running speed, but in much better colors.

But if it can really cut on the heat, that will be a very fine improvement.

I look forward to finally being able to run PhotoShop without any bumps.

You should be able to get that to at least 20,000 GHz with water cooling.

LOL You may be right!

But they should create a new technology like quantum cooling. You program the CPU to look at (him)self as cold...

In a previous work, the scientists found that the switching process of one of the spins in only one ten-trillionth of a second - that's 0,000 000 000 000 1 seconds - takes place, making them ideal for the new components to the extremely high switching frequencies of theoretically up to 10,000 GHz can be expected.

(From the given link)

It should be noted that this is the switching speed of a single "spintronic gate." This would not be the operating frequency of more complex circuits and processing pipelines to be built off of such technology - which would likely run substantially slower, in only 100s of GHz to 1-2 THz at maximum.

Further - the process is entirely different from semiconductor logic gates (which use Metal Oxide Semiconductor Field Effect Transistors... MOSFETs) - which are voltage-driven. Spintronics are a derivative of quantum computers. The process involves very little comparable power - orders of magnitude lower. Heat-sinks would be a thing of the past on processing and memory components - they may only get a degree or two warmer than ambient temperature and that would be mostly from the on-die interfaces to more standard electronics rather than the processing/memory architectures.

It should also be noted that what was developed sounds similar to a form of non-volatile RAM (which is not much different than an SSD - the only difference would be the application). It does not sound like they have made a processing matrix off of it - though I am sure that is merely a matter of time.

The technology is nowhere near ready for commercialization - five years, maybe, if there is a focused effort to bring it to light - ten to fifteen more likely due to the added complexity of fabrication and the stark deviation from silicon-based lithographic technologies.
