What Is a Dual Processor Motherboard?

Dual CPU means that the computer system has two independent physical CPUs. The entire system relies on the motherboard to coordinate two simultaneous work. The performance is theoretically double that of a single CPU. Dual CPUs are generally used on systems with high computing requirements such as servers. Due to high power consumption and high cost, and the two CPUs must be compatible with each other, dual CPUs are rarely seen on personal computer platforms.

Dual CPU

Dual CPUs are two

First, several working principles and concepts

Layout structure of two or three

If we compare the CPU to a house, then

Performance comparison of the three

The key to CPU performance is the speed. So how do these three perform in terms of speed? We still distinguish by metaphor.

Suppose the CPU is a transport truck, and the cargo is the information we want to calculate. The CPU operation is similar to the truck transporting cargo. The more goods shipped at the same time, the stronger the computing power of the CPU.

Single CPU system-equivalent to a truck running in a lane. Because there are few cars, the transportation capacity is limited. In the past, CPU manufacturers have been continuously increasing the truck's load, that is, the main frequency to improve his transport capacity.

Dual CPU system-equivalent to two trucks running on two intersecting lanes. Most of the cars run on their own roads, but occasionally meet and stop to avoid. Due to the multi-road width of the car, the dual-CPU transport capacity is the strongest.

Therefore, through the comparison of the above structure and the comparison of running performance, we can draw the following conclusions: that is, in terms of running performance, dual CPU> dual-core CPU> hyper-threaded CPU> single CPU; and it is also dual-CPU> dual-core CPU> hyper-thread CPU> Single CPU.
