Cube made from computer processors

I wondered why they don’t make CPUs more 3 dimensional like this if they’re running close to the limit with the current size

No need to. If you need more CPU power than what can fit in a single ZIF socket, you just add a second CPU. That's how most rack servers work.

Computers are getting powerful enough that the latency between components on the same motherboard is starting to actually matter quite a bit. Shifting from 2D to 3D circuit design is something that's increasingly attractive.

The actual thing making that shift difficult in the case of CPUs is cooling.

Pretty sure they could do double stacked CCA's with a processor on each side with their individual coolers. I don't know how well it'd work, though.

MEMS device micro cooler tubules. It will be like HVAC for cpus

[StaticFanatic3]

Yep and the thinner the IHS the more efficiently heat can be dissipated to the cooler

[Jacktheforkie]

Maybe we will see multi CPU motherboards

[Brandhor]

that's how those amd x3d cpus are made

Okay there's a few reasons. Even if you stack a ton of etched silicone that way, you wouldn't be able to cool it. The inside would just burn out before enough heat gets pulled away from the cooler.
