The silicon gap between these two phones is substantial. The Realme C73 5G runs on the MediaTek Dimensity 6300, built on a modern 6nm process node, while the Poco C71 relies on the Unisoc T7250, manufactured on an older 12nm node. A smaller process node generally means greater power efficiency and more headroom for performance — and the benchmark scores bear this out decisively. The C73 5G scores 782 single-core and 2012 multi-core on Geekbench 6, compared to just 437 single-core and 1461 multi-core for the C71. The single-core gap is especially telling, as it reflects the snappiness of everyday tasks like launching apps, typing, and navigating menus — areas where users will feel the difference in daily use.
Supporting hardware reinforces this gap further. The C73 5G's CPU runs its performance cores at 2.4 GHz versus the C71's 1.8 GHz, its GPU clocks in at 950 MHz against the C71's 850 MHz, its RAM operates at a faster 2133 MHz compared to 1866 MHz, and it doubles the L3 cache to 2 MB versus 1 MB — all factors that compound into a noticeably more fluid experience under load. The C71 does ship with 6 GB of base RAM versus the C73 5G's 4 GB, which can help with background app retention, but both phones support up to 12 GB maximum memory, softening that advantage.
The Realme C73 5G wins this category convincingly. Across every meaningful performance dimension — CPU speed, GPU clock, memory bandwidth, cache size, and real-world benchmark scores — it outpaces the Poco C71 by a wide margin. The extra RAM on the C71 is a minor consolation that does not offset the fundamental chipset and architecture disadvantage it carries.
