Moore’s Law is dead – Long live the chiplet

#122Earlier quoted context omitted.
The issue that you seem to be skirting around but not mentioning is, the chance a chip has a defect increases with die area since defects are randomly distributed across the surface of the wafer. Chiplets are a way for manufacturers to practically increase die area while keeping yields high.
In case it's not obvious the implication is that cost per good part starts to go up quickly. The wafer size and cost is essentially fixed so bigger dies mean both a lower % of parts are good and also fewer fit on the wafer in the first place. Wrong kind of hockey stick chart.

#123Moore’s law is alive but the benefits are diminishing. Until 2005 or so, shrinking transistors automatically increased speed and reduced power consumption. When that ran out of steam, the industry went to multi core and massive parallelism with GPUs. Until recently each shrink also lowered the cost per transistor, but that seems to have run out also and has something to do with why Intel was stuck at 14nm for so long…
The problem is that GPUs are mostly underutilized outside games and machine learning, because the industry still hasn't moved away from the concept only a few selected group of developers can enjoy tooling to program them. So everyone that works in other domains, without access to libraries written by the GPU druids, largely ignores their existence.
