[quote]The writing is on the wall for the silicon chip. Transistors have been shrinking for the last half a century but they cannot get smaller forever. Most industry pundits think that the downscaling of silicon chip technology cannot extend much beyond 2026. The big question, of course, is what will replace it. One possibility is graphene, which various teams around the world have used to make hugely fast transistors. Last year, one team clocked a graphene transistor at a cool 427 GHz. So you could be forgiven for thinking that graphene is the perfect silicon replacement. Not so fast. There is a significant problem with graphene that makes it difficult to use in transistors– it has no band gap. That means there is no energy range in graphene in which electron states cannot exist. Or in other words, it’s impossible to switch off graphene. And for a transistor, that spells serious trouble. Today, Guanxiong Liu and pals at University of California, Riverside, say they’ve found a way round this that allows graphene transistors with no band gap to work in an entirely different way to conventional switches. “The obtained results present a conceptual change in graphene research and indicate an alternative route for graphene’s applications in information processing,” they say.[/quote] [url]http://www.technologyreview.com/view/518426/how-to-save-the-troubled-graphene-transistor/[/url]
Wowee batman, that's a lot of power.
Again, it's mind boggling that they think they can get another 13 years out of Silicon.
F yeah Graphene
-snin-
[QUOTE=Sgt. Lulz;41912044]Wait, doesn't this effectively mean that integrated processor graphics will be feasible and won't be as utter shite? If so, I'm so in.[/QUOTE] Or integrated CPU in the graphics card, like what Nvidia was working on.
[QUOTE=Sgt. Lulz;41912044]Wait, doesn't this effectively mean that integrated processor graphics will be feasible and won't be as utter shite? If so, I'm so in.[/QUOTE] Not really. Graphics cards have transistors too, you know. IGPs being more shit is just the fact that IGPs are - by definition - integrated. Intel IGPs were traditionally just scrounged out of whatever die space was left available on the die and their engineers haven't been alloted more die space for graphics until recently (a bigger die = higher heat, power consumption, slower clock speed) so it's not really design capability that's limiting Intel, but rather overall heat/power consumption/cost-effectiveness.
Graphene never ceases to amaze it seems.
I'll believe it when I see it shipping.
Due to the thermal conductivity of graphene, wouldn't it also be an amazing heatsink?

[QUOTE=IrishBandit;41912712]Just because the hardware isn't improving doesn't mean the software can't, see X360 initial releases vs X360 modern releases.[/QUOTE] Old software is insanely fast now, everything installs in under 5 seconds and the loading times are just gone. It's only made as efficient as it has to be, a wait time reduction of a tenth of a second doesn't sell even if that wait happens once a minute on a home computer.
[QUOTE=vexx21322;41912690]Due to the thermal conductivity of graphene, wouldn't it also be an amazing heatsink?[/QUOTE] i dont think a 1 atom thick heatsink would do well
[QUOTE=Shadaez;41913127]i dont think a 1 atom thick heatsink would do well[/QUOTE] Layer it and use it in conjunction with more contemporary materials. Another problem, however, is that graphene has the same problems that asbestos has/had, aka little microscopic pieces will fuck you up pretty badly and you might not want to be putting that kind of stuff next to your big, vibrating, spinning, air-circulating fans.
Your move, carbyne.
Cool I want that power then I can have more tabs open at once and run minecraft with 60fps
I wonder if I can be made into a processor that can run Planetside 2
[QUOTE=ScottyWired;41913205]Your move, carbyne.[/QUOTE] Imagine if we combine Carbyne and Graphene. Carbene and/or Graphyne. It would pretty much literally be Jesus.

Since the heat would have a shorter distance to conduct through the copper than a normal heatsink, it would still be effective.
[QUOTE=Shadaez;41913127]i dont think a 1 atom thick heatsink would do well[/QUOTE] Are you kidding?! It'd be fantastic! The surface area to volume ratio would be IMMENSE! It'd dissipate heat insanely quickly. There'd be NOTHING but the adjacent air for it to dissipate heat into.
[QUOTE=DeEz;41913468]At this point I wouldn't be surprised if inhaling it would grant you superhuman abilities[/QUOTE] it's like asbestos on steroids, you sure you want to do that?

Now wait for quantum computer to come, they'll be even faster!
If I was to be really optimistic maybe Skylake will use Graphene.
