how old are you? dont matter if you have 20 more years on you, you will probably see quantum computing thumb.gif

8 years ago nobody thought possible to have computers with 8 processors with 4Ghz clock speed.

why aren't more people looking at graphene? if IBM used it more, we could have some really nice processors out there!

The circuit handled frequencies up to 10 GHz, and its performance was unaffected by temperatures up to 127 degrees Celsius.
i mean this stuff is like a carbon nanotube on crack

In February 2010, researchers at IBM reported that they have been able to create graphene transistors with an on and off rate of 100 gigahertz, far exceeding the rates of previous attempts, and exceeding the speed of silicon transistors with an equal gate length. The 240 nm graphene transistors made at IBM were made using extant silicon-manufacturing equipment, meaning that for the first time graphene transistors are a conceivable—though still fanciful—replacement for silicon.

No, but they thought we would have 10GHz single cores, but that didn't happen either. Predicting the future is not something that's likely to become true since usually tech branches off like the invention of multi core's to increase computing power instead of clock speed.

Interesting article. It's going to take some real thinking outside the box for them to get this manufacturing process right. carbon nano-tubes are going to be everywhere in the future, no doubt these chips will cost a fortune though thumb.gif

if a Bull Dozer Module were capable of leaving a single core for a WR OC attempt then they would reach near 10Ghz OC (WR)

Its simple..A: there is not really a market for something that powerful currently. B: it is incredibly difficult/expensive to work graphene so it has an on off state.

i think that there is a market for something that can utilize the full potential of graphene. i mean, you see ibm making huge super computers that are made to track missiles and junk, so why not make some processors that can shave the size down a ton.

while it is hard to produce now, if there was a need for it, we would look into ways of mass producing it.

ibm isnt staying idle thats for sure ,they have been at the atom level for more then a decade!first time i heard about it they wrote ibm with atom!

That's what carbon nanotubes are: graphene, rolled into a cylinder.

From the wiki on carbon nanotubes:
Quote:
[Carbon nanotubes] can be conceptualized by wrapping a one-atom-thick layer of graphite called graphene into a seamless cylinder.
