01CPU ( central processor ) CPU is the central processor, which is the core of a computer and has the highest core frequency of the entire computer. When purchasing a CPU, we must consider the performance, price and personal use. Do not pursue a certain item without thinking. ·The two major CPU brands, Intel Intel: Currently occupies the mainstream of the notebook market and has high stability and performance. The i3i5i7i9 we often see is the company's! AMD Ryzen: It has high cost performance, and its performance is close to Intel, and its explosive performance is strong! R5R7 is a typical example! ●Select CPUi3/i5/R5 according to needs: meet daily entertainment, office, and learning! Play ordinary games and media graphic creation can be done i5/i7/R7: Faster processing speed meets professional software such as video editing, anchor industry, database, CAD drawing, i7/i9/R9: high-end processor, gamers and high-performance players who need to pursue the ultimate gaming experience and office experience
CPU parameters How to view Intel: i7-12700K Ryzen: R7-5800Xi7/R7: Common brand identifiers are i5 i7 i9/R5 R7 R9, generally speaking, the larger the number of processors of the same generation, the better the performance! i9i7i5/R9R7R512/7: Gen identifier Gen means generation, indicating the x generation, this example is the 12th generation/5th generation. Generally speaking, the newer the algebra, the better the performance! Intel 12th generation is the mainstream, and Ryzen 5th generation is the mainstream! 700/800: SKU value/model is StockKeepingUnit. Generally speaking, when the suffix is the same as Gen, the larger the number, the better the performance. K/X: Product line suffix
motherboard Intel, if you want to multiply the CPU frequency, in addition to the CPU with K or X, you also need motherboard support. You must have motherboards starting with Z or starting with X, such as Z370/Z390/Z490/Z590, or X99/X299. If you want to over-memory, you must also need a motherboard starting with Z or X. ·HTM1AMD, all motherboards support over memory frequency , while over-CPU frequency requires non-A series motherboards (such as B450, B550, X570), A series motherboards such as A320/A520, which means that except for the two motherboards in front, other motherboards support CPU overclocking. The motherboard now mainly considers four companies: ASUS , Gigabyte , MSI , and ASRock . When it is necessary to reduce the motherboard budget, I just want to use it by default. You can consider the motherboards of second-tier manufacturers such as Colorful , Mingxuan , etc. ●The corresponding motherboards of the third and fifth generation Ryzen in AMD include: B450, X470, B550, and X570. Among them, ZEN2 products can consider using B450/B550 motherboard. ZEN3 products can consider using B550 motherboard more. The 12th-generation Core currently has H610, B660, and Z690 motherboards that can be used for the 11th-generation and 10th-generation Core mid- and low-end products. You can consider using the H510 motherboard and the B560 motherboard to use
03 graphics card (GPU) graphics card is an important component that determines the display speed and screen display effect. Its performance index mainly depends on its video memory/digit number! The display chips of mainstream graphics cards are mainly manufactured by two major manufacturers: NVIDIA and AMD. Taking on the task of outputting display graphics, graphics cards are very important for those who like to play games and engage in professional graphics design. ● integrated graphics card graphics card functions are integrated into the CPU, and there is no independent graphics card! Advantages: low power consumption, stable performance, low price Disadvantages: ① Inconvenient replacement and upgrade ② Not high performance large 3D games cannot afford to play Recommendation: Daily office, general budget choice independent graphics card Advantages: ① Exist separately, easy to upgrade and replace ② Performance Faster speed Disadvantages: power consumption, high power consumption, large heat generation, suggestions: Professional drawing, people who pursue high performance experience choose graphics performance refer to GTX1650RTX3050RTX3050TiRTX3060 RTX3060TiRTX3070RTX3070TRTX3080 The general independent graphics card is stronger than the integrated graphics card, but it is not absolute! The performance of some core graphics cards is stronger than the entry-level independent graphics card!
04 memory memory, also known as "internal memory", and hard disk can be called "external memory". The information in the external memory must be tuned into the internal memory before it can be used by the CPU, so memory is the bridge for the communication between the CPU and the external memory. Regarding memory capacity issues, if you want to use Windows smoothly, you can consider 8-16GB of memory capacity for mild purposes; if you want to play most large games without barriers, it is recommended to have 16-32GB of memory.Regarding memory channel issues, mainstream products only support dual-channel memory at most. For example, i7-12700K, which is a dual-channel memory product. Generally speaking, it is best to consider inserting two or four. Whether it is a dual channel or a four-channel motherboard is a dual memory slot or a four-channel memory slot. The dual slots of the motherboard that supports maximum dual channel memory are also dual channels, and the four-channel slots are also dual channels. If you insert a single memory, it is a single channel. Regarding the number of memory. For dual-channel memory platforms, if there are only two memory slots, it is recommended that you insert them all; if there are four memory slots, it is recommended to insert two first, for example, to meet a capacity of 32GB, 16GBx2 first.
05 Hard disk is a carrier for storing data. Its function is to read and store data. How much software or resources you can store depends entirely on the size of the hard disk, but it is not the only factor! Hard disk classification mechanical hard disk (HDD): It mainly improves the storage space of the computer. Mechanical hard disks look at the rotation number. The larger the rotation number, the better the performance! (such as 5400 rpm 7200 rpm) solid-state drive (SSD): The sequential reading and writing speed of solid-state drives can reach several times that of mechanical hard disks, which will significantly improve data loading. In daily use, if you open a document and have a solid-state drive, you can achieve the advantages and disadvantages of solid-state drives and mechanical hard disks above 0.5 seconds. Mechanical hard disks (HDD): The advantage is that they are cheaper, especially the capacity of 2TB or above, and the price advantage is quite obvious; the disadvantage is that they have weak anti-seismic and fall capabilities, and they are louder. Solid-state drives (SSD): The advantage is that they are faster, faster response, anti-seismic and fall-resistant, have better experience, and are noiseless. Computers that pursue silent can only use solid-state drives; the disadvantage is that they are expensive and difficult to recover data. It is recommended to have a solid state drive when choosing. If you don’t store much data, 512G is enough, and you can choose 1T or larger if you have enough budget. You can also choose solid-state drive + mechanical hard drive!
06 Power supply The power supply of the desktop is a very important hardware in the computer. It is related to the operating health of this computer. Therefore, we must not shrink when choosing a power supply. The power supply is not that expensive compared to the two giants of CPU and graphics cards. Generally speaking, the power supply will account for 5-10% of the entire machine budget. ●For the gold medal of 80Plus, you must first clarify one point of view - "Having 80Plus certification does not mean that it is a good power supply, but good power supply usually has 80Plus certification, and those without 80Plus certification are garbage." Currently, the 80Plus certification from high to low power supply includes 80Plus titanium gold medal, 80Plus platinum medal, 80Plus gold medal, 80Plus gold medal, 80Plus silver medal, 80Plus bronze medal, and 80Plus white medal. This 80Plus certification mainly targets the "conversion rate" and "power factor" standards of power supply. The higher these two standards, the higher the ranking of the corresponding power supply. The easiest way to understand it is - this is the difference between power saving levels. Generally speaking, there is no garbage for power supplies with 80Plus platinum and titanium gold certifications. Some of the power supplies with 80Plus gold certifications are garbage, and there will be more garbage products for power supplies with 80Plus silver, copper, and white certifications. What does it look at whether the power supply is good or bad? ①. The voltage is cheap ②. Cross load ③. Conversion rate ④. Ripple and noise ⑤. Holding time ⑥. Dynamic response
07 Heat dissipation Generally speaking, the heatsink we are talking about is aimed at the CPU, and of course it is actually customized for GPU/memory, but what we say is basically aimed at the heatsink of the CPU. Radiator classification: air-cooled heat dissipation: It can be understood as tower-type air-cooled heat dissipation (single tower four heat pipes, six heat pipes) water-cooled heat dissipation: There can be integrated water-cooled heat dissipation (240 water-cooled, 360 water-cooled, which can actually be called air-cooled) and split-type water-cooled heat dissipation points that need to be paid attention to, whether it is an air-cooled radiator or a water-cooled radiator, there are good or bad. It is not necessarily a high specification (for example, 360 cold radiator, 6 heat pipes, etc.), and the heat dissipation efficiency is definitely one level lower than the specifications. The pit here is relatively large, so just a brief explanation; top-level air-cooled is basically the 240 water level of the current good water-cooled water, so if you want to have strong heat dissipation efficiency, you still have to be high-end cold radiator (the mainstream cold radiator is basically free of water leakage); generally radiators will be marked "can solve XX watts of power consumption". Just look at this value, which does not mean that each can press the power consumption of this value. Finally, I hope everyone can get a computer that suits them!
