The TP-Link Archer AX20 and Archer AX23 both support MU-MIMO (Multi-User Multiple Input Multiple Output) technology, which allows multiple devices to communicate with the router simultaneously. However, there are some differences in the overall performance and capabilities of these two models.

Archer AX20:

• Wi-Fi Standard: Wi-Fi 6 (802.11ax)
• MU-MIMO: Yes, supports MU-MIMO
• Speed: Up to 1.8 Gbps (1201 Mbps on the 5 GHz band and 574 Mbps on the 2.4 GHz band)
• Processor: Dual-core CPU
• Other Features: Beamforming, OFDMA, Target Wake Time (TWT), 4-Stream connectivity

Archer AX23:

• Wi-Fi Standard: Wi-Fi 6 (802.11ax)
• MU-MIMO: Yes, supports MU-MIMO
• Speed: Up to 1.8 Gbps similar to AX20 (1201 Mbps on the 5 GHz band and 574 Mbps on the 2.4 GHz band)
• Processor: Slightly enhanced compared to AX20, provides more efficient data processing and potentially better performance under heavy loads.
• Other Features: Similar to Archer AX20 but potentially more optimized for efficiency and reliability under concurrent device load.

Comparison of MU-MIMO Capability:

• Both the Archer AX20 and Archer AX23 support MU-MIMO technology, enabling them to handle multiple devices simultaneously, thus reducing latency and improving overall performance for connected devices.
• The core difference may lie in the enhanced CPU and processing capabilities of the AX23, which can provide more efficient data handling and potentially deliver a more stable and efficient performance when multiple devices are using the network concurrently.

Conclusion:

While both routers support MU-MIMO and offer similar maximum speeds, the Archer AX23 may have an edge in terms of processor performance and efficiency, which could translate to a somewhat better experience when dealing with a larger number of simultaneous connections. However, both models are quite similar in their overall specifications and performance for average home usage.
