It is actually two things.... heat density and heat leakage.
Of course, these will be more dense.
However, these (like all new processes) will also be leaky as well until the process matures. This is most likely the issue with Ivy.

...quad-cores have been done.
The answer to your question is "Amdahl's law": www.wikipedia.org/wiki/Amdahl's_law
"The speedup of a program using multiple processors in parallel computing is limited by the time needed for the sequential fraction of the program."
More cores will hit a workload limit always
. Faster cores will never hit a workload limit (assuming sub-systems are capable of keeping up).Edited by DuckieHo - 5/14/12 at 9:40am
