At the heart of the performance gap sits the chipset. The Realme 14 Pro runs on the MediaTek Dimensity 7300, built on a modern 4 nm process, while the Realme 14x 5G uses the MediaTek Dimensity 6300, fabricated at 6 nm. A smaller process node means more transistors packed into the same space, translating directly into greater computational efficiency, lower heat generation, and better battery-per-performance ratios. This foundational difference cascades through every benchmark: the 14 Pro scores 823,250 on AnTuTu versus the 14x 5G's 422,130 — roughly double the throughput — and leads in Geekbench 6 both single-core (1026 vs 782) and multi-core (2932 vs 2012). In everyday terms, the 14 Pro will handle demanding apps, multitasking, and gaming with considerably more headroom.
Memory configuration compounds the advantage further. The 14 Pro ships with 12 GB of LPDDR5 RAM running at 6400 MHz, compared to the 14x 5G's 8 GB of LPDDR4 at just 2133 MHz. Faster RAM means the processor can feed data to the CPU and GPU more quickly, reducing bottlenecks during intensive tasks. Similarly, the 14 Pro's GPU clock of 1047 MHz edges out the 14x 5G's 950 MHz, which — combined with the stronger overall chip — results in smoother graphics rendering in games and video. Storage capacity also favors the 14 Pro at 512 GB versus 256 GB, doubling the space for apps, media, and files.
Both phones share structural similarities — 8-thread big.LITTLE CPUs, integrated graphics, DirectX 12 support, and LTE — so the architectural philosophy is aligned. But the execution is in entirely different leagues. Across every measurable performance dimension, the Realme 14 Pro holds a decisive and consistent advantage, making it the clear choice for users who prioritize speed, multitasking capability, and future-proofing.
