==================
Computer motherboard brands rank first-line brands: the main features are strong R&D capabilities, rapid launch of new products, complete product lines and excellent high-end products. At present, there are three brands with high recognition: ASUS: the world's largest motherboard manufacturer, and it is also recognized as the first brand of motherboards, pursuing practicality, especially high-end motherboards, with strong overclocking ability; At the same time, his price is also the highest, and some low-end models also have relatively poor products. MSI: Shipments are in the top five in the world, and the annual campus tour MSI is very popular among college students. Its main feature is complete and luxurious accessories, but its overclocking ability is not excellent. In addition, some low-end models have shrunk seriously, making counterfeiters often find opportunities. Gigabyte: Shipments are comparable to MSI. It has always been famous for its gorgeous workmanship, but it is by no means flashy and overclocking is not outstanding. With the shrinking of MSI, low-end models are often plagued by fakes. Quasi-first-line brands: The three major manufacturers all have the same "fault", that is, they focus on Intel, but they are somewhat careless about AMD platforms with relatively small sales volume, so several motherboard brands focusing on DIY market have emerged. Although they are not as famous as the Big Three, the quality of the motherboards is not inferior at all, so we temporarily list them as quasi-first-line brands: ABIT: overclocking has always been the top priority, and the materials used for work are not inferior to the first-line brands, so they are favored by many DIYER. In the survey of well-known foreign media, upgrading skills ranked second after ASUS. Because the upgrade technology only does DIY market, the motherboard shipment is not large, and the domestic reputation is almost the same, so it can only live in the quasi-first-line position temporarily. EPOX: Originally named Pan Ying, it was renamed Panzheng because it was squatted in China. Similar to the style of upgrading technology, overclocking ability is well known, accessories are relatively complete, and the price is relatively low, so there are more fans. Second-tier brands: slightly inferior to first-tier brands in some respects, but they all have considerable strength and their own characteristics: Foxconn: a subsidiary of Hon Hai Group in Taiwan Province Province, China, has now ranked second in the world in motherboard shipments, catching up with ASUS-of course, most of them are OEM and OEM. Two years ago, it entered the mainland market with the brand of "Fuben", but it ended without results. The real private brand has only entered the DIY market for more than a year. At present, the acceptance is not high and the product line is incomplete, but I believe Hon Hai can do better with its strength. Elite (ECS): Shipments once surpassed Asustek and took the top spot. Unfortunately, it was overtaken in the last two years, and now it ranks third in the world. Different from other big manufacturers, the elite has always taken the low-cost route, the motherboard materials are mediocre, the overclocking ability is almost zero, and the accessories are also the most basic. However, only two years later, the elite also tried to change and launched a high-end "extreme" series of motherboards. We expect the elites to perform better. INTEL (Intel): The name alone is definitely more influential than ASUS, but it is entirely OEM. At present, all of them are made by Foxconn, and the materials used for work are unknown, but they can't be overclocked at all, and there are few accessories, which are despised by DIYER, which is more suitable for families and enterprises. Qingyun (Qingyun): It was founded by high-level officials in Gigabyte, and it is known as "first-line quality, second-line price", and it has indeed been achieved. All aspects are no less than the first-line manufacturers, the price is lower, and the overclocking ability is outstanding. It is not very famous at present. But I personally like this brand, and with its strength, it can completely enter the ranks of first-line manufacturers. BIOSTAR: It is also a world-class motherboard manufacturer, but it only entered the DIY market in the last two years ... >>
