To determine network card performance, consider the following factors: 1. Transmission speed: It is a crucial indicator for assessing network card performance. Generally, the higher the transmission speed, the better the performance of the network card. However, it does not necessarily mean that the highest transmission speed is suitable for all application scenarios. You should choose an appropriate transmission speed based on your actual needs. 2. Stability: The stability of a network card is crucial for the smooth operation of the entire network system. A stable network card can ensure continuous and accurate data transmission. You can evaluate its stability by reviewing product evaluations, test reports, or conducting actual use tests. 3. Compatibility: When selecting a network card, pay attention to its compatibility with your computer or other network devices. Different operating systems and network equipment may have different requirements for network cards. Choosing a network card with good compatibility can avoid various problems caused by incompatibility. 4. Power consumption and cooling: The power consumption and cooling performance of the network card are also important aspects in determining its performance. Low power consumption and good cooling performance can ensure the stability of the network card during prolonged operation. 综上所述，通过以上步骤和方法，你可以在选购网络产品时准确判断网卡的性能，从而选择到适合自己需求的产品。
