A few days ago, the much-anticipated flagship of Meizu announced as Meizu Pro 6 was rumored to integrate the new Samsung Exynos 8890. But today, we learned that MediaTek has announced an evolution of its flagship processor intended to be the heart of Meizu Pro 6. That SoC is known as MediaTek Helio X25.
Meizu selected MediaTek Helio X25 instead of Samsung Exynos 8890?
Meizu broke its relationship with Samsung because the Korean manufacturers didn’t want to introduce a phone with the powerful Exynos 8890 so soon in the market, as Samsung Galaxy S7 came fresh from the factory.
Another reason is that the ChineseSoC manufacturer ‘MediaTek’ upgraded their Helio X20 to Helio X25, solving the temperature issue found in X10 and X20. Thus, the new 10 cores protagonist is now faster, better and reliable than ever before. Let us see how the Helio series has improved.
MediaTek Helio X25 – Overclocking the previous one ‘Helio X20’
Firstly, may we refresh you by reminding you that the Helio X20 is the world’s first SoC to appear with 10 cores using a Tri-Cluster architecture that distributes the load and consumption of the processor as needed. In simple words, the 10 cores are divided into three groups. On the first hand, we have Quad-Core Cortex-A53 running at 1.4 GHz in the low consumption section (utilizes the low power dissipating processes). On the other hand, we have Quad-Core Cortex-A57 running at 2.0 GHz in the midsection (utilizes the mid power consumption processes ). At the end, we are left with the extreme section integrating Dual-Core Cortex-A72 running at 2.3 GHz. The graphic is in charge of a GPU Mali T880 MP4 @ 780 megahertz, arguably the weakest point of this “processor”, if we consider graphics solutions as powerful present in the Snapdragon 820, Exynos 8890 or the best Apple A9X. Thankfully, still we have a high-end GPU which supports cameras up to 25 megapixels (or two cameras of 13 megapixels) and 4K video. Moreover, it also supports quick charging Pump Express Plus V3.0.
So what are the changes in MediaTek Helio X25? The first change is in the core section where Dual-Core Cortex-A72 has increased to a frequency of 2.5 GHz from 2.3 GHz. A surprising thing that came out from the old presentations by MediaTek is that Helio X20 already supports Cortex-A72 at 2.5 GHz, which was then lowered to 2.3 GHz.
The rest of the cores remains unchanged, enabling us to have an increased performance of up to 9%. The second change comes in the frequency of GPU. The old Mali-T880 MP4 has improved from the frequency of 780 MHz to 850 MHz. With this increase, the graphics power of Helio X25 increases from 106 to 115.6 GFlops, standing somewhat closer to the 122.4 GFlops the Kirin 950 Huawei is able to offer its Mali-T880 MP4 @ 900 megahertz. So, the overall change is not a massive one. Surely, it won’t promise Meizu Pro 6 to be on the top of every benchmark as Pro 5 did, last year.

Let’s see that whether the new MediaTek Helio X25 tends to score a good position in benchmarks or fails like Helio X20. The pressure is on Meizu and MediaTek as the upcoming flagship ‘Meizu Pro 6’ is dependent on it.
