First let me explain what is Moore Law:
This law is named after Gordon Moore, who observed in 1965 that number of transistors in processors of modern personal computers are going to be doubled using the same space every two years.
This law was working perfectly but when Intel started production of 1st generation of i3, i5, i7 processors, the limit proposed by Moore's law reached to its maximum value. In the recent release of 6th, 7th and now 8th generation of processors by Intel, there has not been much improvement of speed.
In recent event of GPU Technology Conference (GTC) China 2017, Nvidia CEO Jensen Huang said that the modern development in GPU field have diminished Moore’s Law
This is true also in terms of calculation that GPUs are more efficient than CPUs. For example back few years when Bitcoin launched in 2009, its mining started with CPU, which became obsolete then it shifted towards GPU and then eventually towards ASIC hardware. Now, nobody can even imagine doing mining of any coin on CPU. So according to statement of Jensen Huang, CPUs will definitely eventually become obsolete.
What i think is that even the era of GPU is also towards its end because in terms of mining, we know all popular coins are experiencing higher difficulty rate for mining. For time being, GPUs are solution for complex calculations. In 5-10 years, whole game is going to dramatically change when commercial Quantum Computers will be launched and we will be talking about Quantum cryptocoins and their mining.
Let's see what future unfolds for us and i would love to hear your opinions on this.
