Electronics/Fastest Desktop processor (CPU) in future.
The Current fastest Desktop CPU processor is running at 4.4GHZ clock speed.
Is it possible to design fastest Desktop CPU in future which will run thrice or twice the Current fastest clock speed of 4.4 GHZ?.
I suppose you are familiar with Moore's Law which states that doubling of the storage and processing occurs about every 18 months. This pattern has been going on, pretty much, since the famous Dr. Moore coined the phrase. Much to the disbelief from various experts these technical improvements have been going on for a long time.
Therefore, based on historical trends it would be safe to say that doubling in 18 months will occur. How? No one knows, it just keeps happening.
From a technical point of view the increase in speed is very demanding and the scientists must find ways to decrease the spacing between all the parts and circuits of the chip in order to achieve such vast improvements. But, that is what they do and each engineer or laboratory must make small improvements until gains are made.
Actually, there are chips available now that have higher clock speeds but are not necessarily faster for computing time. There are many factors go into the matter of computational speed and clock frequency is only one element. Not all cpus are the same; they specialize in functionality, internal storage and processing methodology.
It would take some more in-depth investigation to predict the next generation cpu solutions. Maybe for another day.
But, to answer your question, it is my opinion that such clock speeds you have suggested will come to pass in due time. But, it's only an opinion not a scientific analysis.
