On paper, the two chips are closer than they might seem — both are built on a 4 nm process and share identical 12 GB RAM, DDR5 memory, and 3200 MHz RAM speed. But the benchmark data tells a clear story: the Exynos 1580 in the Galaxy A56 5G consistently outpaces the Snapdragon 7 Gen 3 in the Honor 400 5G. The A56 scores 932,578 on AnTuTu versus 845,000 for the Honor, and the gap widens in Geekbench 6, where the Samsung leads in both single-core (1360 vs 1122) and multi-core (3893 vs 3256) results. In day-to-day terms, the A56 will handle demanding apps, multitasking, and sustained workloads with a more comfortable headroom.
The GPU picture reinforces this. The Xclipse 530 in the A56 runs at 1300 MHz versus the Adreno 720's 950 MHz, and the A56's memory bandwidth is a striking 51.2 GB/s — exactly double the Honor's 25.6 GB/s. Higher memory bandwidth directly reduces bottlenecks when the GPU is processing complex scenes, making the A56 the stronger choice for graphically intensive gaming.
The Honor 400 5G counters with one practical advantage: 512 GB of internal storage versus the A56 5G's 256 GB, and support for up to 16 GB of RAM in higher-spec configurations versus the Samsung's 12 GB ceiling. For users who accumulate large libraries of photos, videos, or offline content, that storage lead matters. Still, on raw processing and graphics performance, the Galaxy A56 5G holds a clear overall edge in this category.
