Performance
The vivo X300 and X300 Pro boast MediaTek’s latest and greatest flagship chipset, the Dimensity 9500. The silicon promises a substantial leap in performance over the previous Dimensity 9400 generation in nearly every aspect, not just performance, but also efficiency.
The chipset features an octa-core CPU with a familiar 1+3+4 core configuration, but the cores themselves are based on a new generation Arm CPU cores with an “All Big Core” design. The main core is the Arm C1 Ultra clocked at a whopping 4.21GHz, paired with 3x C1-Premium cores ticking at 3.5GHz and 4x C1 Pro running at 2.7GHz.
The GPU is an Arm G1-Ultra, offering higher performance, lower power consumption, and improved ray tracing capabilities.
Another interesting bit about the new MediaTek chipset is the close collaboration with vivo. MediaTek and vivo have formed a strategic partnership and have worked closely to develop the Dimensity 9500. Moreover, the in-house image processing chip that vivo has been using in its phones, the V3+, is now an integral part of the Dimensity 9500, and from what we gather, other smartphone manufacturers can leverage it as well.
Now off to the benchmarks.
When compared to the previous generation, the X300 and X300 Pro perform roughly 25% better in pure multi-core and single-core scenarios, which meets our expectations. MediaTek promises a 17% increase in multi-core performance and a 32% improvement in single-core workloads.
The newer GPU, on the other hand, delivers a more modest 19% increase in performance over the Dimensity 9400’s Imortalis-G925 GPU, which is well below the promised 33% performance gain by MediaTek. Still, we believe the nearly 20% increase in graphical performance is pretty solid.
The Dimensity 9500 isn’t too shabby when facing rivaling solutions either. The chipset comfortably outperforms the Snapdragon 8 Elite and even the overclocked “for Galaxy” version of the silicon. We see this in CPU, GPU, and combined benchmarks, such as AnTuTu.
The only Android chipset that currently outperforms the Dimensity 9500 is the newly released Snapdragon 8 Elite Gen 5. Even then, the X300 Pro comes pretty close to the Xiaomi 17 Pro Max in the Geekbench’s single and multi-core scenarios. The Snapdragon 8 Elite Gen 5 outpaces the Dimensity 9500 by 2-3%. Surprisingly, the vivo X300 Pro with the Dimensity 9500 is looking better in the combined AnTuTu 10 benchmark, compared to the Xiaomi 17 Pro Max.
We also ran some stress tests to see how the X300 and X300 Pro handle longer workloads.
