Performance
Under the hood, the vivo iQOO Z1 is powered by the Mediatek Dimensity 1000+ chipset. This 7nm SoC, coupled with an octa-core processor, includes four Cortex-A77 cores clocked at 2.6 GHz and four Cortex-A55 cores at 2.0 GHz, providing an excellent balance between power and efficiency. The Mali-G77 MC9 GPU ensures smooth graphics performance, catering well to gamers and power users. Although it initially ships with Android 10 and iQOO UI 1.0, it is expected to support software updates that can enhance performance and add more features. The absence of a memory card slot might be a drawback for some, but with internal storage options ranging up to 256GB paired with up to 12GB of RAM, the phone offers considerable storage capacity directly out of the box.
