Connectivity specs are remarkably well-matched across the board — both phones support 5G, Wi-Fi 7, dual SIM, NFC, USB Type-C, and an identical sensor suite including GPS, gyroscope, compass, accelerometer, and infrared sensor. Peak cellular throughput is also identical at 10000 Mbits/s download and 3500 Mbits/s upload. For the vast majority of connectivity use cases, a user would experience no practical difference between the two devices.
The single meaningful differentiator in this category is Bluetooth. The Realme GT8 Pro ships with Bluetooth 6, while the Redmi K90 Pro Max carries Bluetooth 5.4. Bluetooth 6 introduces improvements including more precise device positioning, enhanced connection reliability, and better coexistence with other wireless signals — benefits that matter most for users with multiple connected peripherals or those who rely on Bluetooth for audio, wearables, or accessories in congested wireless environments. It is not a night-and-day upgrade in everyday use, but it is a forward-looking advantage as more accessories adopt the newer standard.
The Realme GT8 Pro takes a narrow edge here solely on the strength of its newer Bluetooth 6 implementation. Every other connectivity and feature data point is identical between the two phones, making Bluetooth version the only differentiating factor in this category. It is a modest advantage today but positions the GT8 Pro as the more future-ready option for wireless peripheral compatibility.
