Both phones are powered by the Qualcomm Snapdragon 6 Gen 4 on a 4 nm process node, with an identical CPU configuration, Adreno 810 GPU, and matching memory architecture — so the silicon foundation is exactly the same. Where they diverge is in the memory and storage tier: the Realme 14 5G doubles down with 12 GB of RAM and 512 GB of internal storage, versus the P3's 8 GB RAM and 256 GB. In practice, the extra RAM on the 14 5G means more apps can stay resident in the background without being killed, which benefits heavy multitaskers and users who switch frequently between demanding applications.
The benchmark results, however, tell a more complicated story. AnTuTu scores are essentially tied at roughly 684,000 on both devices — consistent with sharing the same chipset. Yet the Realme P3 posts notably higher Geekbench 6 scores: 1104 single-core and 3105 multi-core, compared to the 14 5G's 784 and 2104 respectively. This divergence between AnTuTu parity and a significant Geekbench gap on identical silicon is unusual, and users should weigh it with some caution as benchmark conditions and software optimization can influence results.
Taking the data strictly at face value, there is no clear overall winner. The Realme 14 5G holds a practical advantage in RAM and storage headroom, while the Realme P3 leads on Geekbench throughput scores. For users who prioritize raw storage capacity and multitasking comfort, the 14 5G is the stronger pick; those focused on benchmark-measured CPU performance would lean toward the P3.
