When you buy a mobile phone or pick up a computer, you always have big, dense parameters. Cpus, gpus, stockpiles, and a list of nouns are easily biased by propaganda, and no suitable equipment can be purchased at any cost. Today, these core terms are used in big words, all of which are knowledge that can be used on a day-to-day basis, and it is easy to see parameters after reading white。
Core operating class: “brain” and “shock” of equipment
Cpu (central processor)
In short, the brain of the digital device, which controls all operations。
Opens micro-letters, brushes short videos, typists in office, all under cpu command and control。
The core numbers are like people working, four cores of daily life, eight cores of games and video cutting。
The higher the main frequency (ghz), the faster the single task is handled, the difference in daily usage is minor。
Gpu (figure processor)
Corresponds to the visual nerve of the device, which specializes in video-related work。
The special effects of playing games, drawings of videos and retrofitting are the product of gpu。
The mobile phone gpu is often integrated with the cpu, and the computer is divided into graphic cards (office) and independent graphic cards (play/creation)。
Soc (system-scale chip)
The “processor” commonly used in mobile phones is soc, which integrates cpu, gpu, base belt, etc。
The equivalent of a “family barrel”, a chip has all core functions of computing, communication, display, etc。
It's common to have a soc type of a mobile phone。
Category of storage: “temporary workstation” and “permanent storage cabinet” of equipment
Ram (run memory/carrying)
It's a temporary workstation. The app that's opened is put here for the time being。
To determine how much software can be hanged backstage at the same time, 6g is barely enough, 8g is the mainstream, and more than 12g cannot open carton。
Cell phones are marked with 8 gb, 12 gb, and computers with 16 gb, which refers to the size of the shipment。
Rom (body storage/flash)
The equivalent of a permanent locker, where photographs, videos and app installation packages exist, is not lost。
128 gb start-up is sufficient, 256 gb is suitable for users who take photos and download videos。
Common ufs 3. 1, ufs 4. 0 are cell phone flash specification, and the larger the number, the faster it is read and written。
Lpddr/nvme
Lpddr is the low-capacity transport standard for mobile phones/light copies, and lpddr5 is more energy-efficient and faster than the old ones。
Nvme is a computer high-speed solid-state protocol, much faster than the old hard drive, load-up game。
Screen type: the "window" with the greatest daily visibility
Resolution
In short, the screen is clear, and the more pixels the image is。
1080 p is sufficient base, 2k is clearer and delicate, and more than 4k is used for high-end tablets/computers。
Low-resolution screens, reading the text, blurry pictures and long eyes。
Refresh rate (hz)
The number of times a screen is refreshed, the higher the value is smoother。
60hz is the basis, and daily video is enough; 120hz high screens, slides, play games and hand not caden。
Now, the thousands of machines are largely equipped with 120 hz screens, and the experience is particularly visible。
Brightness (nit)
The maximum brightness that can be achieved by the screen can be seen in the outside light。
The daily use of more than 500 nit is sufficient, the high-end machine can reach more than 1,000 nit, and the outdoor viewing screen is not difficult in the summer。
Colour field
In short, the colour range that can be displayed on the screen, the bigger the color range, the more real。
The daily use of 100% srgb is sufficient, and it is more appropriate to choose 100% dci-p3 colours for movies and drawings。
Iv. Continue and restoration: the eyes to delivery
Battery capacity (mah)
The cell's “storage” value continues for longer。
The mobile phone, 4500 mah, is a pass line, 5,000 mah is the mainstream, and the heavy use is fine。
The light version is commonly 40wh-60wh, with a daily office capacity of 6-8 hours。
Charge power
The higher the charge, the faster the charge。
Cell phone 30w is the basis, 65w closes at 70% for half an hour and 120w super closes at 10 minutes。
Computer 65w is fast enough to provide more than 100w power for high-end games。
V. Photo class: without pursuing high pixels, understand these
Pixels
The size of the photographs increases the number of times the pixels can be magnified。
Not the higher the pixels, the better, the 100 million pixels and 50 million pixels on a daily basis, the smaller the circle of friends。
Sensor size
The greater the size of the camera, the clearer the night view, the more the color。
The larger the sensor size, for example, 1/1. 3 inches is stronger than 1/2 inches。
Aperture (f)
The smaller the f, the brighter the night, the better the background。
Daily host f/18. 8-f/2. 0 is sufficient and night view is selected for f/1. 5 and above。
Networks and interfaces: determining the speed and usefulness of connectivity
5g/4g
Mobile phone network, 5g faster than 4g, downloading a film for a few seconds。
Videos, tweets, 4gs are enough; large files are regularly downloaded, cloud games are played and 5g machines are selected。
Wi-fi 6/wi-fi 6e
Wi-fi 6 is faster and more stable than the old standard for wireless network connections。
Home routers support wi-fi 6, cell phone matching, video-painting, game-playing, non-carton。
Usb-c/hdmi
The usb-c is a mainstream interface that can be used to charge, transmit and access monitors。
The hdmi interface is used mostly for computers/televisions, connected monitors, projectors, large films, and easier to view。
Systems and others: small details affecting daily experience
System version
Cell phones 14 and ios 17, computer windows 11, new version of which is more fluid and more secure。
You don't have to follow the newest, steady and fit for your own app。
Dispersion specification
Cell phones/computer heat-dissemination, games, long office hours, heat-dissemination is hard for carden and hot。
Mobile phones are commonly used for vc liquid cooling, graphite dissipation, computer-based fan + radiator tubes, and more stable heat release。
Body mass
The glass backboard is of good quality and good hand, but it is easily broken; plastics are fall-resistant and cheap。
Most of the boxes are metal, which improves the sense of the mass and is more durable with the metal selection。
Real, objective and small
The variety of parameter terms and the speed of updating, the short time available to ordinary users, and the fact that some manufacturers promote key information can also simplify and be confused. Also, different equipment parameters are suitable for different scenarios, and the numbers alone do not match their own needs or may be suitable products。
Final summary
It's not that hard to understand digital parameters, but the core is to distinguish between the broad categories of “brain” (cpu), “workstation” (carrying), “stores” (storage), “windows” (screen), so that you can choose your own daily airport view. It is best not to follow high-end parameters blindly。
Have you ever been bypassed by parameters when you used to buy digital products? What other terms can't be understood? Let's talk in the comment section. Let's talk about the pit
