1. The overall performance of both phones is similar. A820 is Mediatek's 2G main frequency quad-core U, 8720Q is Marwell's 2G main frequency quad-core U, and the graphics card is SGX544 integration. Are 1G running memory plus 4G storage, support expansion. Antutu comprehensive performance running points are also similar, the former about 13100 points, the latter about 13400 points. In terms of screen performance, Coolpad's 8720Q is a 5-inch 720P resolution high-definition screen with a definition of 294PPI.
1, hello, the mobile phone is used by MTK. As for the brand is also a lot of, different brands of tablets are used are not the same.
2, Snapdragon 855: the most advanced mobile processor in the Android camp, the major mobile phone manufacturers are equipped with this processor as a publicity point, in the eyes of businesses, as long as equipped with the latest Qualcomm Snapdragon processor will be a big seller.
3, mobile phone processor brands are: Apple (A14), Qualcomm Snapdragon, UnitedFatek Teguet, Huawei's Hisilin, Samsung's Orion Exynos and so on. Apple's A-Series Processor (A14) Based on TSMC's 5nm process, the A14 chip uses the Cortex A72 core, which offers 8 times the logic density, 15 percent faster speed, or 30 percent lower power consumption compared to 7nm (first-generation DUV).
4, computer cpu ranking: Intel Core I5-4590, Intel Core i5-4670K, Intel Core i7 4790K, Intel Core i3-4150. Both are recommended. The processor is divided into standard pressure and low pressure, the game generally uses standard pressure processors, and more are i5-8300H, i7-8750H, i9-8950HK.
1, BCM54684 is the second generation of the country's most advanced 65 nm eight-port Gigabit Ethernet transceiver chip solution. Optical network eight-port full gigabit POE switch adopts the sleeve of BCM54684BCM53314. It's just as good on a fiber optic transceiver. For detailed usage, ask a Broadcom agent to find out Marwell chip .
2, fiber three-layer access, Risconda recommended. Switch, see Marwell chip You need, backplane packet switching rate is different. Do not know why you want to switch optical fiber LAN, because the distance is long? It is recommended that you find the engineering team to do the welding, and the welding instrument seems to be cheaper in China to 50,000.
3. So, thisThe core switch is best to choose a little brand, a little guarantee, such as H3C, relatively safe, of course, if you have money, it is best to use Cisco. As an aside, in addition to the core switch, it is the most direct device that affects the stability of the system, in addition to the number of video recorders NVR and hard disk HD also have to pay attention to, both of which will affect the stability of the entire system in the medium and long term, as for how to guarantee not to say much, you understand.
4, can, just enough, a camera H.264 coding, 2 million maximum stream 125M, add up to just 80-90M, but the premise is yourThe difference between computers, which models are mainly on the market (domestic)? What exactly is the configuration? _ Baidu... '> The difference between MID and tablet computer, which models are mainly on the market (domestic)? What exactly is the configuration? _ Baidu... The
is the Mobile Internet Device Marwell chip , a new Internet terminal Marwell chip that is "larger than a smart phone Marwell chip and smaller than a notebook">, is a product between a smartphone and a netbook Marwell chip ; The tablet computer generally uses intel processor and Windows operating system, with a complete computer and tablet functions, support exe program, it and commonly used computer functions are almost the same, but the input part becomes Marwell chip handwriting instead of keyboard and mouse.
So the two actually have the essential difference, the tablet computer is a standard computer, but the input device is replaced by the touch screen, the bodyHigher parts integration allows for smaller volumes. MID, on the other hand, is just a mobile device with storage like a mobile phone, but with more computer functions than a mobile phone. It is not a computer.
tablet is umpc, the system is divided into windows, win xp tablet, meego, linux, ubuntu, wince, android. The difference between umpc and mid is a netbook without a keyboard, the size is more than 9 inches, the cpu is at least 1g frequency, some accessories and netbooks, notebooks are common, with many micro-hard disks, no otg, little hdmi.
1, hard disk is the main computer storage media, hard disk is equivalent to the computer warehouse, operating system, installed software, as well as documents, information, etc., are stored in the form of data (0 and 1) in the "warehouse". The operation of the software is also to first transfer the data into the memory, the CPU is to interact with the data in the memory, and the final result is put into the external memory, that is, the hard disk. Therefore, the hard disk is one of the important hardware that the computer does not divide.
2, say the computer hard diskThe bigger the better, I think is wrong, I don't think the bigger the better, is the size is enough for the right. General household, the configuration of a 500G hard disk is almost, you must be as big as possible, configure 5 hard disks, a 1500G, a total of 7500G. You don't use that much hard drive space, it's a waste.
3, the larger the capacity of the hard disk, the more things you load ~1G=1024M 1M=1024K 1K=1024B Generally speaking, the capacity of a DVD is 640M, 80g=1024x80=81902m. To witYou can already install more than 100 movies alone, so the average home computer is enough to surf the Internet, play games, and download movies. Too much is not needed, and empty is wasteful.
4, secondly, the 5-inch hard disk power consumption is low, because of its small size, so the need for power is also less. In contrast, 5-inch hard drives consume more power. This means that if you need to run your computer or server for a long time, then a 5-inch hard drive can help you save energy. However, a 5-inch hard drive also has its advantages. First, 5-inch hard drives typically have higher RPM and larger cache, so they can provide faster reads and writesSpeed.
5, there are often multiple stacked disks inside the hard disk, so the hard disk capacity = single disk capacity x number of disks, the unit is GB, the hard disk capacity is of course the bigger the better, can hold more data. In particular, the capacity of a single disk also has a certain impact on the performance of the hard disk: the larger the capacity of a single disk, the higher the density of the hard disk, and the magnetic head can read more information in the same time, which means that the read speed can be improved.
1,The A platform is an integrated computer platform provided by semiconductor manufacturer AMD, and the integrated platform that integrates AMD processors, AMD chipsets and AMD graphics cards (ATI graphics cards) is called the AMD 3A platform. Because CPU, GPU, chipset these three core components are the crystallization of AMD research and development, so the "3A platform" has more excellent stability and compatibility, in addition in terms of cost performance, power consumption, the advantages of the "3A platform" are also very obvious.
2, A platform refers to the AMD processor, AMD chipset and AMD graphics card composed of the computer platform. The firstFirst, let's examine these three components in detail. AMD's processors, such as the Velocirons, Ryzen and other series, have been widely recognized for their high performance and good cost performance. AMD chipsets are the bridge between the processor and other components of the computer, which determines the efficiency and stability of the computer's data transfer.
3, A platform is an integrated computer platform provided by semiconductor manufacturer AMD, the integration platform that integrates AMD processors, AMD chipsets and AMD graphics cards (ATI graphics) is called AMD 3A platform. Its functions are: 1. Effectively integrate previously separate components intoTogether, the PC system has the overall optimization design. 2.
