Common desktop computers are made up of:CPU, GPU, motherboard, memory, hard disk, cooling, power supply, chassisThese eight pieces are composed.
However, due to personal budget reasons, sometimes we have to reduce our budget on some parts in order to improve the specifications of other major parts.
So inIn the purchase of daily desktop computers, which of these eight major items can be saved?
The CPU (processor) is the core component of the whole computer, just like the human brain, without the CPU host, it cannot run normally.
The main reference data for CPU purchase are: frequency, core, thread, etc.
Graphics cards are mainly responsible for image computing and output capabilities, and are also widely used in the field of AI.
But for PCs,If you don't have a lot of complex image processing work on a daily basis, you can directly choose a CPU with a core display, and you don't need to use an additional GPU.
Note: Some processors do not have a GPU, such as Intel processors with an "F" suffix for the version without GPU, such as 12400F, 12490F, etc.;If there is no "R" letter in the AMD processor, it means the version without a GPU, such as Ryzen 5 5600U, Ryzen 7 5800H, etc.
The motherboard is the basic platform responsible for carrying CPU, GPU, memory, hard disk and other accessories, and it is also an indispensable part of the successful construction of a computer.
The memory module is the temporary storage place for computer data calculation, and it is also an essential part of the installation. The memory is divided into D2, D3, D4, and D5, taking DDR4-2666 as an example, 4 represents the version, and the larger the number, the more advanced. 2666 represents frequency, and the higher the frequency, the faster the read and write speed.
Hard disks are where daily data is stored, and common types of hard disks are divided into SATA and M2 of both. SATA is large in size and needs to be docked with the motherboard through a data cable, m2. The submission is small and can be plugged directly into the motherboard, and the corresponding interface is not the same, and the transmission speed is not the same, m2＞sata。
The power supply is like the heart of the human being, usually according to the conversion efficiency of the power supply is divided into white label, bronze medal, silver medal, gold medal, platinum, titanium, daily use of the gold medal.
The power supply is divided into different wattage sizes, before purchasing the power supply, we can add up the power consumption of all accessories and calculate, and choose a slightly larger than the actual power supply.
The heatsink we usually talk about has CPU heat dissipation and chassis heat dissipation, CPU heat dissipation is a must, and case heat dissipation depends on the actual situation.
A good chassis combines beauty, heat dissipation, convenience, and functionalityIf you want to save on your budget, you can also do without a case, just open or shoebox.
Summary: Before buying a computer, it is best to determine your own budget, and then choose the right supporting hardware according to your daily needs, and be sure to pay attention to the compatibility between various components, so as to ensure maximum performance.
