Why are CPUs flat
Why are CPUs flat
1. The longer the route, the slower it moves, and the descent from the top of a pyramid is significantly more complex than a simple flat square.
2. Pyramids demand many layers that introduce extra difficulty.
3. Silicon is delicate and a pyramid setup makes it prone to breaking (since glass often uses silicon and quartz).
4. What cooling methods would work for such a structure? Specialized heatsinks might be required.
5. Reduced output – larger wafers increase defect risk, particularly with silicon in a pyramid form.
We might see a prism-like CPU cluster with a mesh design in the future, as we struggled to build enough connections using stacking or faced space constraints. Perhaps a central biological hub surrounded by regular or quantum CPUs could emerge—though this remains largely science fiction today.
presently the design is flat so all cooling can be applied uniformly across the entire die, not just in sections. This approach also simplifies production and reduces costs. In the future this could shift, but I believe it would be driven more by consumer affordability than technological needs. For a sci-fi scenario: a quantum-linked die that operates effectively without physical proximity or location constraints.
