Are CPUs Not Going to Get any Faster?
We’ve come to expect increased performance from each new line of CPUs to be introduced in recent years, but the next generation of CPUs have apparently hit a wall in terms of speed. There are several reasons for this, including bandwidth limitations, but the most serious is power consumption and heat. Modern CPUs consume more power than their predecessors and generate so much heat they have reached the limits of what they can do speedwise, at least as currently designed. In the short term, chip manufacturers such as Intel will look to design CPUs that are more efficient and use less power, thus generating less heat, but there are limits to what this strategy can achieve. Perhaps in the future we can expect a radical redesign of how computers process information.
