The raw performance gap between these two phones is substantial. The Poco X7 Pro's MediaTek Dimensity 8400 chip posts an AnTuTu score of 1,663,422 — more than double the Realme P3 Pro 5G's 801,000 on the Snapdragon 7s Gen 3. This isn't a marginal lead; it reflects a fundamentally different performance tier. The X7 Pro's CPU clock speeds are also meaningfully higher across all core clusters, and its Geekbench 6 multi-core result of 6,137 versus the Realme's 3,239 confirms this advantage is consistent across sustained workloads, not just synthetic peaks. For users who run demanding games, multitask heavily, or use intensive applications, the X7 Pro will feel noticeably snappier and more responsive.
The subsystem advantages reinforce this picture. The X7 Pro's memory bandwidth of 68.2 GB/s versus the Realme's 25.6 GB/s means data can be fed to the processor far more quickly, reducing bottlenecks during complex tasks. Its RAM runs at 4267 MHz compared to 3200 MHz, and it supports a maximum of 24 GB RAM versus 16 GB — headroom that matters for future-proofing and heavy multitasking. Storage capacity also differs: the X7 Pro ships with 512 GB of internal storage against the Realme's 256 GB, doubling the space available for apps, photos, and offline media.
The Poco X7 Pro wins this category decisively and it isn't particularly close. The Realme P3 Pro 5G is a capable mid-range performer for everyday tasks, but the X7 Pro operates at a higher performance level across CPU throughput, memory bandwidth, and storage — making it the clear choice for users who prioritize processing power.
