Processor (CPU)
The processor is the heart of a laptop, and its performance directly determines the computer's processing speed and multitasking capabilities. The mainstream processor brands on the market are Intel and AMD. Both Intel's Core series (i3, i5, i7, i9) and AMD's Ryzen series (Ryzen 3, 5, 7, 9) have their advantages. Generally, a higher number indicates better performance, and the number of cores and threads are essential indicators of performance.
Memory (RAM)
The size of the memory determines how many tasks the computer can handle simultaneously. The standard configuration starts at 8GB, but for higher performance demands, 16GB or more would be a better choice. The memory speed also affects overall performance, with DDR4 being preferred over DDR3 for faster performance.
Storage (Hard Drive)
The hard drive can be HDD (Hard Disk Drive) or SSD (Solid State Drive). SSDs have become the mainstream due to their speed, low power consumption, and shock resistance. Starting with 256GB as storage capacity is reasonable, but personal needs may require larger storage space.
Graphics Card (GPU)
Integrated graphics and dedicated graphics cards are two different types of GPUs. Integrated graphics are suitable for daily office work and media playback, while dedicated graphics cards are ideal for gaming and professional graphics processing. NVIDIA and AMD are the two mainstream manufacturers of dedicated graphics cards.
Display Screen
The resolution should be at least 1080p (1920x1080), with higher resolutions like 2K or 4K providing a more detailed visual experience. The screen size ranges from 11 inches to 17 inches, depending on personal portability and usage habits. IPS screens have more accurate colors and wider viewing angles compared to TN screens.
Battery Life
Battery life is crucial for users who need to use their laptops on the go. Generally, a battery that can support 4-8 hours of usage is sufficient for daily needs. However, advertised battery times are often measured under ideal conditions and may vary in real-world use.
Ports and Connectivity
Adequate USB ports, HDMI or DisplayPort outputs, and wireless connectivity features like Wi-Fi 6 and Bluetooth 5.0+ are essential factors to consider, especially for users who frequently connect external devices or multiple screens.
Cooling System
A good cooling system ensures that the laptop does not overheat during extended use, maintaining stable performance. Metal chassis laptops generally have better heat dissipation than plastic ones. The number and quality of fans, as well as the design of heat pipes, can affect heat dissipation.
Brand and After-Sales Service
Choosing a reputable brand of laptops usually ensures reliable quality assurance and better after-sales service. Different laptop brands differ in design, materials, and detail handling, so consumers need to choose based on personal preferences and needs.
