100,000x less energy during "idle"??? what is this "idle" your cpu shouild be running full blast at all times! and im tired of hearing of new materials they are going to use and nothing ever coming from it! intel, amd read this and do it!

It's not about the CPU running, but rather, that the transistors of this new material use less power when in the fully on, fully off state, which is largely where every transistor on a chip is for most of the time. The only time that energy will be used heavily is on the switching edges, but that should be less than 10% of total cycle time. It will make for lower power use in caches, memory, and in those parts of a processor that are not utilized very often - while it probably won't make much difference in those things heavily uses, like the CPU registers, ALU, and so on.

But they do use these new materials - hence why we have blue and white LEDs, stuff that didn't exist except as curiosities twenty years ago. Not only that, but no one could have thought an LED of any colour could be used for much more than a relatively dim indicator, now you can go out and buy ones that will illuminate a whole room.

Of course, the limit for mass producers like Intel and AMD comes down to the ease of fabrication, the cost of equipment, and the suitability of the process. All of this has to be settled, and it remains very, very tough to beat silicon when it comes to price, and the fact that all of their equipment is set up to process silicon. I think Intel's first step is really to bring out USB3, rather than fooling with exotic new materials that they can't deal with.

Tell me about it!

But rest assured that Intel / AMD will be looking at this, vast amounts of money to be made with entirely new tech, but large investments need to be made to develop it. Think how many years it took to learn how to use silicon to the stage we are now.

This is exciting news, but I don't expect to see it in my rig any time soon. Graphene has been around sine 2004, but there is still no commercially available chip made from it.

The problem is going to be availability. Currently molybdenum compounds are used primarily by the alloy industry, with a fair amount being used in the ceramics industry to make refractory bricks. The major reason it's not considered a strategic material is that our current supply far outweighs demand. If we make electronics out of it, that will not be the case.

The beauty of silicon- and carbon-based transistors is that silicon and carbon are two of the most abundant elements on earth! There is still is a lot of molybdenite ore out there to be mined, but that's only relative to demand. If we start using molybdenum compounds the Henderson and Climax mines in Colorado will probably give out in less than half of the time they're currently predicting.

The overall limitation is cost. We have decades worth of knowledge with silicon, established supply chains for silicon, and hundreds of billions invested in silicon fabs.

To change this will take decades...

Startup costs for production aside, I wonder how the price of this compares to silicon.

You can't ignore startup costs if you want to know the price....


To get this to mass production, we're talking at least tens of billions.

Even before the first commercial unit gets produced, there will need be hundreds of millions in R&D, manufacturing, validation, etc.

When? That's all that I want to know.

Of course it'll save energy in active state.
