Yes, we need to realize that inventions like these do not come to the mass market in a few months. That said, this look very promising because of the fact they used the existing fabrication techniques.]]>Feb 7th 2010 1:38PMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/Feb 7th 2010 8:31AMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/He got moore than he bargained for!

The bonus here is that now we can increase sequential calculations. For the last few years, companies have basically just been adding more cores to increase calculations, rather increasing clockspeeds substantially. This is good, but still limits the speed of our applications, as not all instructions can be operated in parallel. This will lift that bottleneck, hopefully.]]>Feb 7th 2010 9:31AMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/
Hopefully this doesn't deter the shift toward multi-threaded programming in general, however. While faster clock speed will always give us linear performance increase; each time intel/AMD doubles the number of cores in their CPUs, performance can potentially increase exponentially. Unfortunately, few development firms have adopted the use of multi-threaded programming needed to take advantage of dual/quad/hex core CPUs. ]]>Feb 7th 2010 9:56AMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/
So true, which is why i'm so glad I haven't upgraded my dual core PC. Quad and Hex cores are coming out but it always takes a long rime for the software makers to support them.]]>Feb 7th 2010 10:14AMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/
And what about power? With 100GHz, we need a water plant to cool down the system.

Off course 100GHz will not be used in the average computer as well.]]>Feb 7th 2010 1:41PMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/
A specific area that was holding things back was games, but thanks to the current HD consoles requiring it (assuming the game has to do any challenging cpu work at all), game developers have had to adapt too.

There are also cases where it's easy and has been done for years (servers).

So anyhow I don't think we have a particular problem in the next year or so; software that requires a high degree of performance will probably all be able to make use of a reasonable number of processor cores. The picture might be a bit different if we ever move to a situation where the number of cores is really high (hundreds) because then the challenges involved start to look more like those currently associated with supercomputer applications...]]>Feb 7th 2010 6:53PMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/Feb 8th 2010 11:50AMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/Unfortunately, your program will run as fast as the slowest linear process.

unfortunately, many engineers end up stuck in cubicles coding all day. You could possibly do work like this, but I think most of the engineers and scientists who do work like this have MSEEs and PhDs in EE specialties specifically related to semiconductors, mems, materials, etc.

I'm sure there are also plenty of physics PhDs there as well. It's a cool field, but tough... so I guess the question is, are you willing to go the research route, and get your PhD as well? It could be rewarding if you're good at it - but otherwise you might just end up hating your life, which is never good. ]]>Feb 7th 2010 2:27PMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/Feb 7th 2010 6:48PMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/

don't get me wrong, it's neat technology, but specifically for laptop cooling I think the real solution is chips with lower power consumption - batteries aren't going to get much better any time soon, so reducing power usage solves both the 'heat' and 'battery life' problems.]]>Feb 7th 2010 6:59PMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/
a) they only measured up to 10GHz and extrapolated towards a possible cut-off frequency of 26GHz
b) they are assuming that, according to the theory, a change in feature sizes would allow frequencies up towards the THz-regime

And, as it often is, it is not trivial to turn theory into operational devices.]]>Feb 7th 2010 12:32PMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/
Until the graphene develops a bandgap and can be doped both n and p type, we won't be seeing it used as a digital switch.

Word up IBM^^ are they going to bust out with something that can give the 6core gulftown a run for its money? A revival of PowerPC? Should be interesting to see how this technology unfolds into application.

Likewise 40GHz in state of the art silicon is really something considering that most all current dual and quad core architectures speed step peak at under 4.5GHz. Looks like there is lots of head room for future GPU/ CPU/ APU/ SOC's to gain performance boosts; lets hope that we can see these speed increases roll out with efficiency improvements; since the better the performance per watt = better battery life (From laptops, to the inverters in battery electric and fuel cell vehicles) improvements to the core material science governing our ability to switch, compress, scale, or otherwise manipulate electrical energy and the information and power it carries; will be crucial to pushing the continued evolution of science and technology.

Since the transistor has been widely hailed at the most pivotal and ubiquitously influential technological development in history; any improvement made to transistor technology has the ability to push forward the boundaries of what is possible into application what currently resides in the realm of imagination.

Onward with innovation ^^ Two thumbs up IBM ]]>Feb 7th 2010 3:13PMhttp://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/http://www.engadget.com/2010/02/07/ibm-demonstrates-100ghz-graphene-transistor/yea tat in theory probably would work but wouldn't that fry up the chip?
Or graphene has very low thermal envelope?

This probably might need a new fabrication process, maybe even lower than 25nm, to operate under a typical TDP]]>Feb 7th 2010 3:20PM
