Recently, many customers have consulted the motherboard parameters of LCD advertising machines, building advertising machines, touch all-in-one machines, smart tablet conferences, teaching all-in-one machines, self-service terminals and other products on the official website. The main board is also the core of the advertising machine, which is very important. This manufacturer will generally give a reference and introduce the motherboard solutions of commonly used building advertising machines.
CPU (CPU, Central Processing Unit) is a very large-scale integrated circuit, which is the computing core (Core) and control core (Control Unit) of a computer. Its function is mainly to interpret computer instructions and process data in computer software.
· intel Intel is an American company that mainly develops CPU processors. It is the world's largest manufacturer of personal computer parts and CPUs. It was established in 1968 and has a 50-year history of product innovation and market leadership. In 1971, Intel introduced the world's first microprocessor
· Entry-level Pentium and Celeron series
· Mid-range mainstream Core i3/i5/i7 series
· High-end Core Extreme series processors
AMD USA AMD Semiconductor Corporation specializes in designing and manufacturing a variety of innovative microprocessors (CPU, GPU, APU (accelerated processor), motherboard chipsets, TV card chips, etc.) for the computer, communications and consumer electronics industries, as well as providing flash memory and low power processor solutions, the company was founded in 1969
· CPU selection
· Should you choose Intel or AMD for a CPU? In the process of purchasing CPUs, no matter which manufacturer's products we choose, there are corresponding models that can meet the needs, so we don't need to be too entangled.
Is the number of cores the more the better? This is a common idea of many users. They believe that the more cores the CPU has, the better its performance, but it cannot be generalized. For a processor, in addition to the number of cores, important parameters include whether to support hyper-threading technology, default main frequency, maximum turbo frequency, whether to support overclocking and other parameters. For example, a native six-core six-thread processor from the same manufacturer, even at the same main frequency, may not perform better than the same series of four-core and eight-thread products.
Is the CPU worth every penny? Although the overall performance of a CPU with a higher price is better, because of competition in the CPU market, Intel and AMD continue to launch corresponding new products for competing products, especially for AMD, the price is very high. an important advantage. In addition, even for products of the same brand, there may be some products with lower prices and better performance due to different product positioning and promotion strategies.
· Should you choose the CPU first or the motherboard first? Generally speaking, it is still necessary to choose the CPU first, because different CPUs need to be matched with motherboards with different chipsets. In the actual operation process, we must have a rough budget ratio, such as a complete machine of 8,000 yuan. Before purchasing hardware, we should roughly plan the budget ratio of CPU, motherboard, graphics card, storage and other equipment. If CPU plus motherboard If the budget can reach 3000 yuan or even higher, then you can choose the combination of i7 plus Z270 or Ryzen 5/7 with X370.
· Is it necessary to choose a CPU with K? Many people who don't know CPU will think that Intel's CPU model with K only means that the product supports overclocking, and for ordinary players, they will not toss the CPU overclocking, so there is no need to buy a CPU with K. This kind of thinking is very one-sided. Friends who are familiar with Intel Core products know that Intel's recent "K" series products not only support overclocking, but also have a much higher default main frequency and turbo frequency than products without K.
Should the CPU be bought in a box or in pieces? Finally, let's discuss the purchase of CPU boxed and scattered chips. Because the CPU itself is extremely difficult to make, there is no problem of fakes or high imitations. In general, the biggest difference between the boxed loose pieces is the warranty. The genuine boxed CPU has an official warranty of three years, while the loose pieces are often Warranty for one year only by the store. In addition, some models of boxed CPUs may also come with original radiators, which makes the price difference between boxed and loose pieces of the same product reach one or two hundred yuan, and the price difference of some popular high-end products may be even higher.
GPU GPU is graphics processor, (English: Graphics Processing Unit, abbreviation: GPU), also known as display core, visual processor, display chip, is a kind of specialized in personal computers, workstations, game consoles and some mobile devices (such as The microprocessor for image computing on tablet computers, smart phones, etc.) is responsible for processing image data, and then outputting it to the display to interact with the user
· APU APU (Accelerated Processing Unit) Chinese name is accelerated processor, it is a processor independently developed by AMD, namely CPU plus GPU, the two are integrated on one chip
· Memory Memory is one of the important components in the computer, it is the bridge to communicate with the CPU. All programs in the computer run in the memory, so the performance of the memory has a great impact on the computer. Memory (Memory), also known as internal memory, is used to temporarily store operational data in the CPU and data exchanged with external storage such as hard disks. As long as the computer is running, the CPU will transfer the data that needs to be calculated into the memory for operation. When the operation is completed, the CPU will transmit the result. The operation of the memory also determines the stable operation of the computer. Memory is composed of memory chips, circuit boards, gold fingers, etc.
· Hard Disk A hard disk is one of the main storage media of a computer and consists of one or more aluminum or glass discs. The disc is covered with ferromagnetic material. Hard disks include solid-state hard disks (SSD disks, new hard disks), mechanical hard disks (HDD traditional hard disks), and hybrid hard disks (HHD is a new hard disk based on traditional mechanical hard disks). SSD uses flash memory particles for storage, HDD uses magnetic discs for storage, and hybrid hard disk (HHD: Hybrid Hard Disk) is a kind of hard disk that integrates magnetic hard disk and flash memory. The vast majority of hard drives are fixed hard drives that are permanently sealed in the hard drive.
