Understanding Moore's Law and Its Impact on Computer Architecture

Published on 2022-05-02

Created by Gordon Moore, the co-founder of Intel, in 1965, Moore’s Law concludes that “the number of transistors in a dense integrated circuit doubles approximately every two years.”

Why is this Important?

There are some major takeaways from this statement that actually bring the future architecture of computers huge benefits.

More Transistors = More Functional Units

Functional units are pieces of a CPU that run operations instructed by a computer program. Examples of functional units are arithmetic logical units and floating-point units. With more functional units, CPUs are able to perform more operations, thus, advancing the technology largely.

More Transistors = More Cores

Basically, the more cores, the better a CPU will perform. Multiple processes are able to run at the same time with more cores which increases efficiency by an insane amount. A single-core CPU is much less efficient when it comes to running multiple processes.

More Transistors = Big Cache

Cache memory is what reduces performance bottlenecks between RAM and CPU. Having a big cache will reduce these bottlenecks even further. This means that the efficiency and speed of a CPU are heavily increased when there is a big cache.

More Transistors = More Complex Management Units

The complexity of management units is important because it means that they can perform more tasks and handle a larger variety of them. There is always the debate on simplicity vs complexity, but if you’re a complexity type of person who wants a more efficient system, then this is your ride!

Moore’s Law also states that the number of transistors doubling is marked to stop in 2025. This is because the future of transistors lies in 1nm chips which are smaller, faster, and stronger.

Conclusion

Understanding Moore's Law and its impact on computer architecture is essential for appreciating the rapid advancements in computing technology. As we approach the limits of transistor miniaturization, the industry continues to innovate, paving the way for more powerful and efficient computing solutions.
