Despite sharing the same 4 nm manufacturing process, the two chipsets in these phones occupy very different performance tiers. The Realme 14 Pro Plus runs on the Snapdragon 7s Gen 3, while the P3 Ultra is powered by the MediaTek Dimensity 8350 — and the benchmark gap between them is substantial. The P3 Ultra scores approximately 1,450,000 on AnTuTu versus the 14 Pro Plus's 801,000, nearly an 80% lead. Geekbench 6 tells the same story: the P3 Ultra pulls ahead in both single-core (1536 vs 1162) and multi-core (4700 vs 3239) results. In practice, this translates to faster app launches, snappier multitasking, and more headroom for sustained gaming workloads.
The memory subsystem widens the gap further. The P3 Ultra's RAM operates at 8533 MHz with a maximum bandwidth of 68.2 GB/s, compared to the 14 Pro Plus's 3200 MHz and 25.6 GB/s. Faster memory bandwidth directly benefits GPU-intensive tasks and data-heavy operations like video editing or rapid file transfers. The P3 Ultra also supports up to 24 GB of RAM versus 16 GB on the 14 Pro Plus, giving it more ceiling for future-proofing and heavy multitasking. The 14 Pro Plus does counter with double the base internal storage at 512 GB, which is a meaningful practical advantage for users who store large media libraries locally.
Raw performance is a decisive win for the Realme P3 Ultra 5G across every meaningful metric — CPU throughput, GPU clock speed, memory bandwidth, and benchmark scores all point in the same direction. The 14 Pro Plus's only offset in this category is its larger built-in storage, but for users who prioritize processing power and system responsiveness, the P3 Ultra holds a commanding lead.
