Quote:Yet another advantage of graphine as the wafer. Shame it will take at least five years for fully functional prototypes.
I still find myself doubting this. Even over at IBM nobody is touting graphene as the magic solution. You still have power dissipation to deal with and graphene won't fix that problem.

There are other ways of dealing with that, though. It's one of the advantages of the triple gate (or whatever they're called) transistors in ivy bridge. Although graphine may not turn out to be the miracle some are calling it, it would have many advantages over silicon if anyone could be bothered to put the work into getting it working. For example we are getting closer and closer to having such small 'wires' in CPUs that we'll have to stop, and will only be able to make better CPUs by making them bigger. Graphine would allow us to continue shrinking the low level construction further than silicon. But again, we may discover something even better, and use that instead.

Quote:i5 or i7?
i5 (better <stock> single-threaded performance, lower temps, longer battery life, lower price)

In a world where chip performance is mainly limited by power dissipation (a.k.a. our world) none of this matters at all. We need to fix the power dissipation issues of high end ICs if we ever want to see significant improvements made to single threaded performance.

And we're already working on that, for example tri-gate transistors in Ivy Bridge, as I mentioned in the text you quoted.
Or, also in the text you quoted,
Usually it's best not to say something is wrong because it doesn't account for what it does account for, as it makes you look like you aren't reading things before saying they're wrong, which is stupid.

But, in relation to dolphin, you don't need the extra cores, as it only uses 2, plus one for LLE audio.

Quad core i5s do exist btw
03-12-2012, 07:17 AM
And hex core i7s exist, so they do have more cores.

Quote:I7 Is Better Then i5 because it has more cores then the i5. but the i5 will give you faster speeds. and i7 is still good if your running a lot of programs like photoshop E.T.C
Quote:Quad core i5s do exist btw
Quote:And hex core i7s exist, so they do have more cores.
Most i5s are quad core (>90%)
Most i7s are quad core (>90%)
Therefore no, i7s don't necessarily have more cores than i5s, in fact they usually don't.

But trigate technology hasn't made a big difference to power dissipation.......
Most of the reduction in power dissipation in ivy bridge is due to the 32nm die shrink. The reduction in power dissipation from ivy bridge is exactly what we normally get when intel does a die shrink (about 25%).
Quote:we may discover something even better
which may have the advantage of fixing many issues, such as power dissipation.
Sure we may come up with some breakthrough technology that fixes the problem but what does this have to do with graphene? Nothing.
The fact of the matter is graphene isn't going to fix the power dissipation problem, end of story. Any technological breakthrough that fixes power dissipation (like photonics for example) will be completely unrelated to graphene wafers.
