Connectivity is where the names of these two phones do most of the talking. The Realme P3x 5G supports 5G, unlocking cellular download speeds up to 3300 Mbits/s — more than ten times the 300 Mbits/s ceiling of the P3 Lite 4G's 4G connection. For users in areas with 5G coverage, this translates to dramatically faster mobile data for streaming, downloads, and cloud tasks. It also makes the P3x 5G a more future-proof choice as 5G networks continue to expand.
There is, however, a notable twist in the Wi-Fi specs. Despite being the more connectivity-focused device, the P3x 5G tops out at Wi-Fi 5 (802.11ac), while the P3 Lite 4G goes a step further with support for Wi-Fi 6 (802.11ax). Wi-Fi 6 offers improved throughput, lower latency, and better performance in congested network environments — so on a compatible router, the P3 Lite holds a meaningful home networking advantage. The P3x 5G also edges ahead with Bluetooth 5.3 versus 5.2 on the P3 Lite, a minor but incremental improvement in wireless stability and efficiency. All other connectivity features — NFC, dual SIM, USB-C, GPS, Galileo, and expandable storage — are identical across both phones.
Overall, the P3x 5G has the stronger connectivity profile, primarily because 5G cellular access is a more impactful real-world upgrade than Wi-Fi 6 for most users. That said, the P3 Lite's Wi-Fi 6 support is a genuine advantage at home or in the office on modern routers, making this a closer call than the 5G label alone might suggest.
