Graphene 1thz CPU + Oculus VR

while we are still years away. i cant help but be giddy at the thought of a 1 thz cpu and what graphene is going to do to electronics such as Oculus VR. 8 to 12k resolution, with graphics better than Avatar, and a world bigger than GTA V..

Think 1 thz cpu (20+ cores) solid state drives. (your cellphone will be far more powerful than the best personal computer we have now...) now hook that up to VR and your not locked into a seat 😛

the future is exciting and i cant wait to play in it!

It is easier to run a single transistor at that speed than a whole chip. But yeah graphene has much potential though that is still far away. We really need new materials we are nearing the limits of the current one.
They just need to solve all problems with graphene and then also build 3D chips and I would be quite happy.

seems like pretty wild stuff.

This is a better article... we are a long way from production:

Wow, that's pretty amazing. Cheap production of high quality graphene? Wasn't expecting that for a while. Here is how it works: [>]

Hope they can use it for those 427 ghz processors!

im trying but i almost cant imagine what games will be like when they hit that 1thz .. 250 times faster than our current tech.. then throw in Oculus VR (when graphene is used) .. and you have a tech that can push the type of VR we can only dream about.. and this stuff isnt 20 years down the road.. it seems to be about 5.

Ok, after some more research... good attempt but try again:
http://www.reddit.com/r/technology/comments/1kr5fw/mit_got_graphene_to_behave_like_a_transistor/cbs5...

So, let's take that 845 GHz number. Loosely speaking, that's a single transistor changing states 845 billion times a second, meaning a single state change takes 1/845,000,000,000th of a second.
Let's suppose for a moment that information could be transmitted through the chip at the absolute fastest speed possible, the speed of light. In that 1/845,000,000,000th of a second, information could have traveled a maximum of 0.354 millimeters.
For comparison, Intel CPU dies for the current 22nm node range from 160 to 264 mm2. If the die is a perfect square, that comes out to 12.65 to 16.2mm on each side. That means that the longest dimension is going to be 17.9 to 23mm, from corner to corner.
That means that in this ideal scenario, where our information is traveling at the speed of light, the results of one calculation will take between 50 and 65 cycles to reach the other end of the chip, and twice as many cycles before the signal can get all the way back to the original end of the chip.
I hope that helps to show why the speed of a single transistor is pretty meaningless when we're talking about an entire CPU. It's kind of like quoting the fastest speed a tire has ever gone, probably by being shot out of a cannon or something similarly ridiculous. It tells you nothing about how fast an entire car can travel, because a single tire and an entire car simply aren't comparable.


So far they have 8 gates (I think), lets wait before we jump on the hype train.

The silicon-germanium heterojunction bipolar transistors built by the IBM-Georgia Tech team operated at frequencies above 500 GHz at 4.5 Kelvins (451 degrees below zero Fahrenheit) - a temperature attained using liquid helium cooling. At room temperature, these devices operated at approximately 350 GHz. Performance measurements were made using a specialized high-frequency test system in the Georgia Electronic Design Center.

This explains why no one is building 40GHz CPUs with gallium nitride... :lol:
