1. Need to buy those things
Motherboard: graphics card, power supply, CPU, memory stick, hard disk, monitor, mouse, keyboard, audio
how to start
First determine the CPU model and then select a motherboard compatible with the CPU (different CPUs correspond to different motherboard slot types)
How to choose a CPU model:
Zhihu Black Shrimp
Main brands: Inter, AMD
Intel Series
X-series chipset: the most high-end series, providing overclocking, multi-graphics support, basically do not consider
Z series chipset: mainstream series, also provides functions such as overclocking, multi-graphics card support, and high-bandwidth memory.
B-series chipsets: low-end series, suitable for entry-level desktop computers and office computers, providing basic hardware support and a small amount of overclocking functions.
H-Series chipsets: Mobile series for notebooks and mobile devices, offering low power consumption, integrated graphics, and more.
AMD series are basically the same
The difference between Intel and AMD
1. AMD is more cost-effective than Intel, but Intel is better in single-core performance, and AMD is stronger in multi-core performance (how to distinguish between single-core and multi-core: games need single-core, video clips need multi-core) 2
. AMD consumes more power, Intel saves more power (inter is more suitable for notebooks)
How to choose a CPU that suits you after choosing a brand
When choosing a CPU, first look at the architecture, second, the number of cores, and then the frequency.
i3 stands for entry-level, i5 stands for mid-range, i7 stands for high-end, i9 stands for flagship. K
means the processor can be overclocked, F means lack of integrated graphics (if If you plan to buy a discrete graphics card, choose the one with F.)
i7-1165G7 means that the processor is an i7-level, 11th-generation processor with 4 physical cores and 8 threads.
Architecture: it is the era version
Currently asked chatGPT
12th generation i7<11th generation i9
12th generation i7≈10th generation i9
12th generation i7>9th generation i9
12th generation i5<11th generation i7
So it seems that i9 is stronger
number of cores
For playing games, CPU stability is more important than the number of cores. For graphics, the number of cores is more important. The
cores are equivalent to the number of CPU cores of workers moving bricks on the construction site.
Generally speaking, a core has only one thread, but now with hyper-threading technology, each core has two. The
upgrade from 6 cores to 8 cores is not a big improvement
frequency
It is equivalent to the speed of a worker moving bricks.
The unit Ghz
represents the computing speed of the CPU.
Baseband
The basic frequency of the CPU is the frequency at which the CPU runs when the load is not high, which is equivalent to the speed at which you are walking.
Choose a high frequency for games.
turbo frequency
The operating frequency of the CPU under high load conditions when the firepower is fully activated, the frequency
i3 does not support turbo frequency
overclock
The ultimate performance of the CPU:
Intel supports overclocking with X and K, and
all models of AMD Ruilong support overclocking.
Under what circumstances should you choose a CPU with overclocking:
1. For high-performance games, overclocking can increase the clock speed of the processor, thereby increasing the number of game frames and response speed
2. Professional applications that need to process large amounts of data or perform complex calculations, such as video editing, 3D animation design, or virtual reality developers
How to match the motherboard
Zhihu Black Shrimp
motherboard brands:
first-tier: ASUS, GIGABYTE, MSI
second-tier: ASRock, Biostar (ASUS)
Only AMD CPUs can be used on AMD chipset motherboards, which are completely incompatible with Intel
Need to refer to different CPU pins
The stitches of the eleventh generation are 1200 stitches, the twelfth generation is 1700 stitches, and the thirteenth generation is also 1700 stitches
Motherboard "chipset" is the core chip on the motherboard. One of its functions is to allow the motherboard to recognize the CPU and then work normally. Different chipsets correspond to different CPUs.
Also refer to the motherboard size
How to choose a memory stick
Usually you can choose DDR4 Kingston.
In the actual test, the 8G is increased to 16G, which has a relatively obvious improvement in game performance, but the 16G is increased to 32G again, which no longer has a significant impact on the number of game frames. At present, 16G can almost meet the memory requirements of all games, and the cost performance of 16G memory is also relatively high
How to choose two 8G or one 16G
Two 8GB memory sticks can increase memory bandwidth and system performance through dual-channel mode. However, using a 16GB memory stick can only work in single-channel mode, and the memory bandwidth is low, which may affect system performance.
How to choose a graphics card
Zhihu Black Shrimp
RTX is a series of Nvidia, and RX is a series of AMD.
RTX series graphics cards focus on image rendering effects and innovative technologies, while RX series graphics cards focus on game performance and efficiency.
NVIDIA graphics cards are called N cards, while AMD graphics cards are called A cards.
Graphics card brand:
N card graphics card brand
A Graphics card brand
Generally speaking, it is recommended to buy an N card. Various softwares are well optimized, more stable, and have stronger performance. is the same, so the performance is almost the same as well. (such as ASUS RTX4070 and MSI RTX4070)
2. Different graphics cards of the same model mainly differ in: brand, appearance design, heat dissipation specifications, materials, quality control, etc. (Although graphics cards with good materials and strong heat dissipation have better performance release potential, the performance difference is very small, generally not more than 3%.)
Public graphics card
Graphics card chip manufacturers Nvidia and AMD have their own branded graphics cards, which are generally called "public version" graphics cards. Generally speaking, the heat dissipation and materials of the public version of the graphics card are average, and the cost performance is not high. However, the "non-public version" graphics cards launched by graphics card manufacturers are better than the public version products in terms of performance and heat dissipation of the same model.
How to choose the right graphics card
The larger the value, the better the performance, 3050<3050ti<3060
How to choose a hard disk

Directly select solid-state drives
Select solid-state drives with M.2 interfaces that support the NVME protocol
Flash memory chip priority: MLC>TLC>QLC
SLC is Single-Level Cell (single-level cell), fast speed and long life, super expensive price, and the erasing and writing life is about 100,000 times.
MLC is Multi-Level Cell (Multi-Level Cell), the speed is average, the life is average, the price is average, and the erase life is about 10,000 times.
TLC is Trinary-Level Cell (three-layer cell), which is slow in speed and short in life, cheap in price, and has an erasing life of about 500-1000 times.
QLC is Quad-Level Cell (four-layer cell), with slower speed, shorter life, cheaper price, and about 150 to 1000 times of erasing and writing life.
