In this article, we will compare the attributes of RTL8821CE and RTL8822CE to help you make an informed choice.

Speed and Performance

One of the most important factors to consider when choosing a wireless network adapter is its speed and performance. The RTL8821CE offers a maximum speed of up to 433 Mbps on the 5GHz band and 150 Mbps on the 2.4GHz band. On the other hand, the RTL8822CE provides faster speeds with up to 867 Mbps on the 5GHz band and 300 Mbps on the 2.4GHz band. This means that the RTL8822CE is better suited for tasks that require high-speed internet, such as online gaming or streaming HD videos.

Compatibility

Another important factor to consider is the compatibility of the wireless network adapter with your devices. The RTL8821CE is compatible with a wide range of operating systems, including Windows, Linux, and macOS. It also supports the latest wireless standards, such as 802.11ac. On the other hand, the RTL8822CE offers even better compatibility with support for newer standards like 802.11ax. This means that the RTL8822CE is more future-proof and will work with the latest devices and technologies.

Range and Coverage

When it comes to wireless connectivity, range and coverage are crucial factors to consider. The RTL8821CE offers decent range and coverage, making it suitable for use in small to medium-sized homes or offices. However, the RTL8822CE provides better range and coverage, thanks to its advanced beamforming technology. This allows the RTL8822CE to maintain a strong and stable connection even at longer distances, making it ideal for larger homes or offices with multiple devices.

Security Features

Security is a top priority when it comes to wireless networking, and both the RTL8821CE and RTL8822CE offer robust security features to protect your data and privacy. The RTL8821CE supports WPA/WPA2 encryption standards, which are considered secure and reliable. The RTL8822CE goes a step further by offering support for the latest WPA3 encryption standard, which provides even stronger protection against cyber threats. This makes the RTL8822CE a more secure choice for users who prioritize data security.

Price and Value

Finally, price and value are important considerations when choosing a wireless network adapter. The RTL8821CE is generally more affordable than the RTL8822CE, making it a budget-friendly option for users who are looking for a reliable wireless connection without breaking the bank. However, the RTL8822CE offers better performance and features, which may justify the higher price tag for users who require faster speeds and advanced security. Ultimately, the choice between the RTL8821CE and RTL8822CE will depend on your specific needs and budget.
