cpu is not the higher the number of cores, the better, the more cores does not mean the better performance, because it also involves software optimization and architecture efficiency issues.
CPU is the core of the entire microcomputer system, it is often synonymous with various grades of microcomputer, CPU performance is roughly inverted
It reflects the performance of the microcomputer, so its performance index is very important. The main performance indicators of the CPU are:
1. The CPU Clock Speed is the CPU clock speed. Generally speaking, the higher the frequency, the faster the CPU. Due to differences in internal structure, not all cpus with the same clock rate perform equally.
2. Memory-bus Speed refers to the communication between the CPU and the second-level (L2) cache and Memory. The cpu is not the higher the number of cores, the better, the more cores do not mean the better performance, because it also involves software optimization and architecture efficiency.

2. Memory-bus Speed refers to the communication speed between the CPU and the level 2 (L2) cache and Memory.
3. Expansion-Bus Speed refers to local buses such as VESA or VESA installed on a microcomputer system
Working speed of the PCI bus interface card.
4. Supply Voltage refers to the voltage required by the CPU to work properly. Early CPU operating voltage one
Generally 5V, with the increase of CPU frequency, CPU operating voltage has a gradual decline in order to solve the problem of excessive heat

5, the address bus width determines the CPU can access the physical address space, for more than 486 microcomputer systems, the width of the address line is 32 bits, up to 4096 MB of direct access to the physical space.
6. The data bus width determines the primary data between the CPU and the second-level cache, memory, and input\/output devices
The amount of information transmitted.
7. Built-in Coprocessor cpus containing built-in coprocessors can speed up specific types of numerical calculations that some require
Software systems that need to perform complex calculations, such as high version AUTO CAD, require coprocessor support.

It should be that the more audits, the higher the single master frequency, the better the performance. But there is also the problem of heat dissipation. Recommended
