Will dual-cored cpu's be thicker?

[Mik3y]

Will dual-cored cpu's be noticably thicker? or will they just have 2 cores in one chip? i'm curious as to how its architecture looks and works, as it being one processor.

The cores would never be above/below each other because that would make the heat dissipation too difficult. Most likely the dies will be more rectangular (less square) with the cores next to each other.

i doubt it, symetry (sp?) is a friend of highly sensitive electronics... in any case, wouldn't they be under a heat spreader, and so, would it matter anyway ?

isnt it possible having 2 cores but it looks like one big core? Would that be better than any heatspreader? Im not a cooling expert but it seems logical to me.

What about the heat sink and fans? Will they begin to get as big as the G5 setup?

i dont think it will be two cores on one chip, but rather one giant core.

 

[oldman420]

it makes sense that the would place two cores along with the controller and connecting circuitry on one large chip to seperate the cores would produce lag as the distance is important to cpu efficiency

Thats exactly what I thought. Seems like the best approach to me.

Yeah, i have always envisioned it as kinda like the two cache pieces in Quadrant III and IV and the two computing pieces in Quadrant I and II; or something allong those lines - just one big rectangular/square piece.

The picture of the amd dual core showed that the two cores would be side-by-side with the L1 and L2 cache wraping around the outside of both of them.

CPUs already have multiple layers of transistors... some as high as 11 layers (consumer cpus).

I could see them getting thicker, but i dont know enough on the subject to know what that entails. I doubt that all 11 layers have transistors on them either...

i'm more worried about heat output of the 2 cores. 1 core is hot enuff itself to run fine on a hsf, but wut about 2. i'm assuming you would need a really powerful fan or water cooling to keep the temp down.

That is wrong. All CPUs have 1 level of transistors, and as many as 11 layers of Wires.
And no, dual core CPUs aren't thicker, they are made on the same wafers as single core CPUs, just wider and taller.

It will be very interesting to see how many slices of cores will be stacked using Sun's radio-pin technology. You could actually stack core upon core in this way, with the logic of the core looking more like a fancy map out of Super Mario Bros.

Proximity communication is not radio pin. It does not use radio waves, but capacitive coupling. And you still have to cool each core. So you can't just put two cores on top of each other unless you have some way to remove heat.

Correct... You can only build transistors into the silicon substrate. The rest of the layers connect all the transistors turning them into various logic components (i.e. logic gates.)
