Moore wrote:The complexity for minimum component costs has increased at a rate of roughly a factor of two per year.
Krogoth wrote:Intel's PR department is trying to keep "Moore's Law" alive by shifting the focus to power consumption reduction, however this has its own limits. We are closing onto the hardware limits of what semiconductor-based computing can do. That's why the new focus is shifting gears onto a new computing model. Quantum computers are getting most of the buzz.

Krogoth wrote:Power consumption is driven both by "clockspeed" and active transistor count.
krogoth wrote:Adding more cores/ICs into the design will still run into the problem of power consumption and thermal output if they are all being utilized.
krogoth wrote:The current power saving schemes on modern chips involved reducing voltage, clockspeed and putting idles parts of the silicon into a "sleep state".
