With the fierce competition between Inter and AMD in terms of processors, general CPU applications have entered an era of dual-core or even 4-core. However, software development lags far behind hardware development. Moreover, software must develop along with the development of hardware. In an article published by Sina technology today, "vendors do not have to worry about the lag of software development when responding to multi-core CPUs.", I agree with the points in this article. As early as AMD launched its first dual-core processor for common users, I found that multithreading and multi-process in the software industry are a development direction of software. If the software industry cannot make full use of multi-core processors through multi-process and multi-thread technologies, users will not feel much improvement in their computer performance. Think about it. Even if you have 100 CPUs, even if you use an NT operating system that supports multi-process technology, most of the existing software is single-threaded, then they can only run on one of your CPUs at the same time. Think about the difference between using a single-core CPU. Therefore, I disagree with the existing so-called dual-core architecture. at least from the perspective of the current situation, the benefits of multi-core technology are not necessarily seen. However, I believe that the emergence of multi-core technology will inevitably prompt the software industry to speed up its multi-process reform and bring people's attention to the multi-process technology. Therefore, I think software development will inevitably develop towards this multi-thread and multi-process direction.
