We need something new, not the same old “add more cameras to the phone” kind of innovations.
It’s the engineers that will make those discoveries—the investors can shove it. All they do is freeload on innovation and cramp peoples style.
The vendor that makes the device definitely cares though I wonder how much Intel cares about consumer oroducts as percentage of mkt share compared to servers.
We can probably still increase the frequencies a bit but we definitely seem pretty close to some fundamental limit in our current understanding of physics. The frequency doublings every other year we experienced until the early 2000's are long gone I'm afraid, and they might never come back until we manage to make a breakthrough discovery in fundamental physics.
Smaller transistors reduce the I, but R goes up with smaller interconnects. The RC time constant also adds delay, probably more so than length.
That being said, 3D stacking won’t help with heat, and dielets won’t help with delay. I rather have 4 cores at 10 GHz than 64 cores at 3 GHz.
