noun explanation

CPU series

The CPU is mainly two series of Intel and AMD. Intel mainly has Celeron, Pentium, Core i3, i5, i7 and Atom series. I5 is currently the most cost-effective. AMD mainly has A4, A6, A8, A10 and E series. The A8 series is more optional.

CPU frequency

The main frequency is also called the clock frequency, and the unit is MHz, which is used to indicate the CPU's operation speed. The CPU main frequency includes two parts: the external frequency and the multiplier. The product of the two is the main frequency. Usually higher frequency desktops can improve certain performance, but it is only one aspect, not higher is better.

DMI2 bus

DMI is a bus developed by Intel to connect the north and south bridges of the motherboard . Now the third and fourth generations of Intel CPUs have completely eliminated the concept of a bus and are fully integrated into the CPU.

CPU socket

CPU sockets are mainly divided into LGA and Socket. Is the socket used to install the CPU. At present, the interfaces of the CPU are pin-type interfaces, and corresponding socket types are provided on the motherboard.

Number of pins

At present, the CPUs are connected to the motherboard using a pin interface, and the CPUs of different interfaces are different in the number of pins. In principle, the performance of the CPU has nothing to do with the number of pins.

Haswell Core

The Haswell architecture is Intel's fourth-generation CPU architecture, inheriting the high-end Core i7, mid-range i5, i3, and low-end Pentium and Celeron markets. Haswell uses the LGA1150 socket. Brand new Intel core.

Number of cores

The core is also called the kernel, which is the most important part of the CPU. The number of cores is also the number of cores. The biggest difference is the number of cores. Generally speaking, the more the number of cores, the stronger the performance and the multi-threading capability.

Craftsmanship

In the process of producing the CPU, various circuits and electronic components are processed, and the wires are connected to each component. Usually the precision of its production is expressed in nanometers (nm), currently 22 nanometers is common.

Instruction Set

The CPU relies on instructions to calculate and control the system. Each CPU specifies a series of instruction systems that cooperate with its hardware circuits when designing. The strength of instructions is also an important indicator of the CPU.

Hyper-Threading Technology

Hyper-threading technology is to use special hardware instructions to simulate two logical cores into two physical chips, so that a single processor can use thread-level parallel computing, which is then compatible with multi-threaded operating systems and software, reducing CPU idle time. Improved CPU operating efficiency.
