IBM reches 26Gigahertz, Terahertz next

[Monkeywoman]

"graphene is going to be the next big thing that will revolutionize transistors and, hence, all manner of electronics, and it looks like IBM is now claiming one of the biggest breakthroughs to date, not to mention the desirable title of "world's fastest graphene transistor." More specifically, IBM researchers have apparently been the first to demonstrate the operation of graphene field-effect transistors at gigahertz frequencies and, apparently even more importantly, they've also established the scaling behavior of the graphene transistors, which they say could eventually lead to the development of terahertz graphene transistors -- or, in other word's, keep Moore's Law around for quite a bit longer than many expected.

y doesn't IBM make consumer cpus again?

[twilyth]

I'm sorry, but it's that kind of news that I can't really absorb until after a hard reset. Where's my mallet?

[Calmatory]

IBM is mainly a research company rather than semiconductor manufacturer, though they have plenty of expertise and knowledge on that field (E.g. AMD 45nm SOI w/ IL).

[roofsniper]

sigh did someone go 100 years into the future to grab this article? because this is just unheard of. terahertz? if it wasn't for hdds no one would know what a tera is.

[G0ldBr1ck]

thats crazy, Wonder if this was done with very few transistors or with millions.

[dinos22]

sooo should we buy Core i7 or wait for this IBM thingie

[Monkeywoman]

i'm curious as to what arch they used. was it a basic cpu only to reach these speeds, or was it a cell or power6?

[Cold Fussion]

Weren't we able to run on these frequencies with gallium arsinide (sp?)

[roofsniper]

i don't think you can wait for that thing. you will most likely have to steal it .

If it's really that fast then maybe apple made a bad move going to Intel from IBM PowerPC?

[Loque]

and I bet we can overclock it to 30Ghz on air :p

I could see AMD buying it. Why not if their new chips cant compete with whatever intels new server chips are

Yeah AMD is all about the non-x86 CPUs.

What the hell are you guys talking about..
The news here is that a GRAPHENE transistor reaches frequencies in the GHz range with is a great news. IBM had depletion FET's at 350GHz at room temperature for years now. If you think that 5-6Ghz is the limit for A SINGLE transistor in a modern CPU, I suggest you read some wikipedia on how a pipeline and a pipeline stage work...

[T_Flight]

OK, I'll come clean...

Here's what happened. You know that wormhole I opened with my latest rig? Well, I reached through it and got sucked to the "other side" and these aliens gave me these transitors. I tried to send them to Intel, but they wouldn't believe me, so I sent them to IBM to be tested. Well, they wouldn't give them back and said they didn't know anything about them. I guess you guys can probably figure out the rest.

Ok, gotcha. I remember a couple years back when they had a transistor hit 500GHz and then I hear this 26GHz and I'm like "so what?" So it's the graphene transistor that's special.

Yep, the clockspeed itself ain't really the news here, just what transistor achieved it. This is probably what is going to replace silicon, so its obviously pretty big news.

........... not even gonna say anything.

[twilyth]

Was it single layer graphene? didn't read article yet. That has some funky properties. I remember something about electrons being able to tunnel through energy barriers with no resistance (which is probably redundant).

Anyone want to volunteer to tutor us/me?

[Glow9]

Yeah AMD is all about the non-x86 CPUs.

yeah I guess AMD has never bought and or used any IBM architecture.

[rob1101]

cant wait, I wanna be in the THZ

[Shintai]

IBM and mass production usually doesnt mix.

[XSAlliN]

Do you guys wanna upgrade your desktop rig to server? - cause this is not meant for desktop market, at least not for current times. That's like upgrading from a car to airplane.

Hey...maybe in years to come that will happen too

I dont care about GHz/ THz per se... its just a switching frequency and frequency can be so easy to do depending on transistor count, architecture and the instructions being used.

New semiconductor techniques are always cool.

Conduction band FTW!
