[Ars] IBM prepares for end of process shrinks with carbon nanotube transistors

The shrinking size of features on modern processors is slowly approaching a limit where the wiring on chips will only be a few atoms across. As this point approaches, both making these features and controlling the flow of current through them becomes a serious challenge, one that bumps up against basic limits of materials.

During my visit to IBM's Watson Research Center, it was clear that people in the company are already thinking about what to do when they run into these limits. For at least some of them, the answer would involve a radical departure from traditional chipmaking approaches, switching from traditional semiconductors to carbon nanotubes. And, while I was there, the team was preparing a paper (now released by Nature Nanotechnology) that would report some significant progress: a chip with 10,000 working transistors made from nanotubes, formed at a density that's two orders of magnitude higher than any previously reported effort.

Didnt their Power CPU were clocked at 4Ghz about 3 years ago? they were Quadcores

Currently up to 5.5 GHz. biggrin.gif

Oh Crap..! I bet this babies could OC much much higher than their stock speed, too bad IBM dont like to do that and their mainframes are way too expencive even for the most acomodated Overclocker

and a Hexacore at that.... but thats a small niche market... most medium range business use off the shelf x86 processors to do just about the same

I'm dying to see what the world would be like when we start using carbon nanotubes in chips. Hopefully I'll be around still when that time comes.
