The performance gap between these two devices is substantial. The Oppo Find X8s runs on the MediaTek Dimensity 9400 Plus, a flagship-tier 3 nm chip, while the Tecno Camon 40 Premier 5G uses the mid-range MediaTek Dimensity 8350 built on a 4 nm process. That one-generation node difference matters: the smaller die size of the 9400 Plus allows for greater transistor density, translating into higher peak performance and better power efficiency under sustained load. The benchmark numbers confirm this decisively — the Find X8s scores 2,880,558 on AnTuTu versus the Camon 40 Premier's 1,380,000, more than double, while Geekbench 6 multi-core results follow the same pattern at 8,969 versus 4,700.
Storage and memory also tell a one-sided story. The Find X8s ships with up to 1TB of internal storage and 16 GB of RAM running at 10,667 MHz, compared to the Camon 40 Premier's 256 GB and 12 GB of RAM at 8,533 MHz. The Find X8s's larger 12 MB L3 cache (versus 4 MB) further reduces latency for demanding tasks. Meanwhile, memory bandwidth reaches 85.3 GB/s on the Find X8s against 68.2 GB/s on the Camon 40 Premier — a difference that shows up in how quickly large assets load in games, photo editing, and AI-assisted features.
The Oppo Find X8s holds an unambiguous and commanding advantage in performance across every measurable dimension — chipset tier, raw benchmark scores, RAM capacity and speed, storage, and cache. The Camon 40 Premier is capable enough for everyday tasks, but users who demand sustained heavy workloads, high-fidelity gaming, or future-proofing will find only one clear choice here.
