We've been out of the Moore's Law window for a while. Processing power no longer really increases in a linear fashion. Instead, manufactures increase throughput by smaller improvements in the processor and by squeezing in more cores per chip. This also means our tasks/programs are changing to utilize more multi-threading capabilities.
The idea of what is high performance has really changed.
- xigency 9y agoMoore's law works on transistor density, so adding cores to a chip can be a continuation of it. The barriers to faster single core performance are power/heat in increasing clock speed and diminishing returns in superscalar architecture. Moore's law is still alive, it's just dwindling now.
- alkonaut 9y ago> Moore's law works on transistor density, I thought it was transistor count in IC's? If we assume that for state of the art chips the area is more or less fixed (by speed of light, manufacturing constraints, thermal constraints etc) then there is no difference between "transistor density" and "transistor count" - but is that the case? Is there no margin for die growth (Disregarding yield/cost - considering only physical constraints)?
