On paper, both devices share the same storage, RAM, process node, and thread count — but the chipsets powering them belong to entirely different performance tiers. The Neo7 SE runs on the MediaTek Dimensity 8400, scoring an extraordinary 1,884,673 on AnTuTu, while the Neo7x's Qualcomm Snapdragon 6 Gen 4 scores 684,046. That is not a marginal gap — the Neo7 SE is nearly 2.75x faster in this benchmark, which places it in flagship-adjacent territory while the Neo7x sits firmly in the mid-range.
The CPU clock speeds reinforce this divide: the Neo7 SE's prime core runs at 3.25 GHz versus the Neo7x's 2.3 GHz, meaning single-threaded tasks like app launches and UI responsiveness will feel noticeably snappier on the SE. Even more striking is the memory bandwidth gap — 68.2 GB/s on the Neo7 SE versus just 12 GB/s on the Neo7x. This affects how quickly the processor can feed data to the CPU and GPU, which shows up in gaming frame consistency, large file operations, and multitasking under load. The Neo7 SE also supports up to 24 GB RAM versus the Neo7x's 16 GB cap, giving it more headroom for virtual RAM expansion.
The Neo7 SE wins this category decisively. For users who game, multitask heavily, or simply want a phone that will remain performant for more years, the Dimensity 8400 offers a fundamentally superior experience. The Neo7x is a capable everyday chipset, but it cannot compete with the SE's raw throughput at any level of the performance stack.
