WIFI 6 (802.11ax) and WIFi 7(802.11be)
1, Transmission Rate
Theorical Max speed of WIFI 6: 9.6Gbps
Typically delivers real-world speeds of 1-2Gbps(depending on conditions)
Theorical Max speed of WIFI 7:46Gbps, about 5times of WIFI 6
Typically delivers speed of 5-10Gbps(or more with optimal setups)
2, Frequency Band coverage
WIFI 6 supports 2.4GHz& 5GHz bands or WIFI 6E()
WIFI 7 supports 2.4GHz, 5GHz and 6GHz bands, coverage from 1GHz to 7.25GHz.
3, Channel Bandwidth
WIFI 6 Maximum 160MHz channel bandwidth
WIFI 7 doubled to 320MHz, higher data transmission capacity
4, Modulation Technology
WIFI 6 adopts 1024-QAM
WIFI 7: Upgraded to 4096-QAM, 4 times higher and increase data transmission efficiency by 1/5.
5, Multi-Device connectivity
WIFI 6 supports 8×8 MU-MIMO, allowing up to 8devices to connect simultaneously.
WIFI 7: supports 16×16 MU-MIMO with Coordinated MU-MIMO, allowing more devices to connect simultaneously in high-density environments.
6 Latency and Efficiency
WIFI 6:OFDMA (orthogonal frequency division multiple access) improves efficiency in multi-device environments
Target Wake Time (TWT) improves battery life for IoT devices
WIFI 7:MLO(Multi-Link Operation) allows devices to use multiple bands simultaneously, reducing latency
Lower latency for gaming, VR, and real-time applications
7 Backward Compatibility
Both WIFI 6 & WiFi 7 are backward compatible with older Wi-Fi standards(Wi-Fi 5, Wi-Fi 4,etc)

The key difference of them in Wireless networking standards. WIFI 7 is much better in transmission speed, frequency band coverage and connection stability and others. It’s ideal for 8k streaming, VR/AR, cloud gaming, and smart homes with dozens of connected devices. But Wi-Fi 6 is still solid for every day use.
