What is a dual-core processor
What is a dual-core processor? What is the meaning of the concept behind the dual-core processor? In short, the dual-core processor is a processor core based on a single semiconductor's processor. In other words, the two physical processor cores are integrated into one core. Enterprise IT managers have always insisted on seeking improvement performance without increasing the method of actual hardware coverage. Multi-core processor solutions provide stronger performance without increasing energy or actual space.
The introduction of dual-core processor technology is an effective way to improve processor performance. Because the actual performance of the processor is the total amount of the processor can process the number of instructions in each clock cycle, adding a kernel, the number of cells executable per clock cycle will be doubled. Here we must emphasize a little thing, if you want the system to achieve the greatest performance, you must make full use of all the executable units in the two kernels: that is, all executive units are active!
Why is IBM, HP and other manufacturers' dual-core products that cannot be popularized, because they are quite expensive, never get a wide range of applications. For example, a dual-core IBM Power4 processor with 128MB L3 cache is 115x115mm, which is quite high. Therefore, we cannot call the IBM POWER4 and HP PA8800's dual-core processors called AMD's upcoming dual-core processor's predecessors.
At present, the X86 dual-core processor's application environment has been quite mature. Most operating systems have supported parallel. At present, most new or upcoming application software provides support for parallel technology, so once the dual-core processor is listed, system performance The improvement will be able to get a rapid improvement. Therefore, the entire software market has been fully prepared for multi-core processor architecture.
Innovative meaning of multi-core processor
The x86 multi-core processor marks a major leap in computing technology. On the occasion of this important progress, it is a global trend of enterprises and consumers in the face of rapid growth, and the processor begins to provide more convenience and advantage. Multi-core processors, compared to current single core processors, can bring more performance and productivity advantages, and thus will eventually become a widely popular computing model. Multi-core processors will also play a key role in pushing PC security and virtual technology, and the development of virtual technology provides better protection, higher resource usage and more considerable business computational market value. Ordinary consumers will also achieve higher performance than ever had more ways, thereby increasing their home PC and digital media computing systems.
Putting up a newly populated world on a single processor to resettle two or more powerful computing cores. Multi-core processors can provide an immediate, economic effective technology to overcome today's processor design challenge - reduced heat and power consumption with the continuous increase of the frequency of the single core processor (ie "clock speed") . Multi-core processors help provide superior performance for more advanced software in the future. Existing operating systems (such as MS Windows, Linux, and Solaris) can benefit from multi-core processors. When the market demand will be further improved in the future, the multi-core processor can provide an ideal platform to reasonably improve performance. Therefore, the next generation of software applications will be developed by multi-core processors. Regardless of whether these applications help professional animation production companies produce more realistic movies, or create a more natural and fascinating PC, using multi-core processor hardware Practicality will always change this computing world.
Although dual-core or even multi-core chips have the opportunity to become one of the most important improvements in the history of processor development. It should be pointed out that one of the biggest challenges facing dual-core processor is the limit of processor energy consumption! Performance is enhanced, and energy consumption cannot be increased. According to the document obtained by the famous Tangshi hardware website, the CPU thermal design of the code SMITHFIELD is up to 130 watts, which is 13% higher than the current Prescott processor. Since today's energy consumption is already a considerable level, we need to avoid making CPUs into a "small nuclear power plant", so the energy consumption problem of dual-core or even multi-core processors will be one of the important issues of AMD and Intel.
