Both phones are built on a 4nm process and share the same thread count, memory generation, and maximum RAM ceiling, but the silicon underneath tells meaningfully different stories. The iQOO Z10's Snapdragon 7s Gen 3 outscores the Tecno Pova Curve 5G's Dimensity 7300 in Geekbench 6 — 3239 vs 2932 multi-core, and 1162 vs 1026 single-core. Single-core performance in particular drives everyday responsiveness: app launches, UI snappiness, and task switching all feel faster when that number is higher, making the iQOO Z10's lead here tangible in daily use rather than just on a benchmark sheet.
The storage and RAM gap compounds the advantage. The iQOO Z10 ships with 12GB of RAM and 256GB of internal storage compared to the Tecno's 8GB and 128GB — differences that matter in multitasking-heavy scenarios and for users who store large media libraries locally. One nuance worth noting: the Tecno's RAM runs at a faster 6400 MHz versus the iQOO's 3200 MHz, which can improve memory bandwidth in certain workloads, but this advantage is largely offset by the iQOO's stronger CPU and greater RAM capacity overall. GPU clock speeds are essentially identical at roughly 1050 MHz, so neither holds a graphics clock advantage.
The Vivo iQOO Z10 is the clear winner in this category. Superior benchmark scores, more RAM, and double the base storage give it a well-rounded performance edge that will be felt across gaming, multitasking, and long-term device longevity as app demands grow.
