Both phones are built on a 4 nm process, but they pair that manufacturing node with very different silicon. The Infinix Note 50x 5G runs on the MediaTek Dimensity 7300, while the Realme P3 Pro uses the Qualcomm Snapdragon 7s Gen 3. Benchmark data consistently favors the Snapdragon: the P3 Pro scores 801,000 on AnTuTu versus 720,000 for the Note 50x, and leads in both Geekbench 6 single-core (1162 vs 1026) and multi-core (3239 vs 2932) results. In real-world terms, this translates to snappier app launches, smoother multitasking under load, and more headroom for demanding games.
Memory configuration further widens the gap. The P3 Pro ships with 12GB of RAM and 256GB of storage, compared to 6GB RAM and 128GB on the Note 50x. Double the RAM means the P3 Pro can keep significantly more apps alive in the background without reloading, a tangible quality-of-life advantage for heavy users. The Note 50x's RAM runs at a faster 6400 MHz versus the P3 Pro's 3200 MHz, but this technical advantage does not meaningfully compensate for having half the capacity. GPU clock speeds are essentially identical at around 1050 MHz, so neither has a clear edge in raw graphics frequency, though the Adreno 710 in the P3 Pro generally handles sustained GPU workloads more efficiently than the Mali G615.
Shared specs — 8-core layouts, DDR5 memory, big.LITTLE architecture, DirectX 12 support, and a 16GB maximum memory ceiling — confirm these are peers in the same tier, not generations apart. Still, the Realme P3 Pro holds a clear performance advantage: higher benchmark scores across the board, twice the RAM, and double the storage make it the stronger choice for users who push their phone hard.
