MediaTek Helio G91 vs Unisoc T612

The lower mid-range/budget SoC segment of the market has had new life injected into it in the form of the Helio G91 Ultimate. How well will this new SoC perform against the older Unisoc T618? Let's find out.

The budget market is the space where most of the unseen competition for buyers takes place. It may not have the glamour of the high-end market but it is just as important. Let's have two of the more prominent SoCs go head to head. This is the MediaTek Helio G91 vs Unisoc T612.

The MediaTek Helio G91 (also known sometimes as the Helio G91 Ultimate) is a budget SoC from MediaTek. Even though it was released in May of 2024, it is not entirely new tho. It is simply a reworked MediaTek Helio G85 with support for 108MP cameras. You can find it on devices such as Itel S24, Redmi 13 and Poco M6.

The Unisoc T612 from Unisoc on the other hand is a lot older as it was released in May 2022. It is also a budget SoC that has suddenly returned to prominence. You can find it on phones like the Realme C33, Realme C51, Realme C53 and Realme N63.

Performance of the MediaTek Helio G91 Vs Unisoc T612

The performance of both SoCs will surely be of the utmost concern to people who are torn between both of these SoCs. This is because the performance of an SoC is what determines the apps and tasks that it'll run and the games that it'll play.

Both SoCs use the same microarchitecture with 2 ARM Cortex A75 CPU cores and 6 ARM Cortex A55 CPU cores. However, the CPU cores on the Unisoc T612 are clocked at 1.8GHz (max) whilst those of the Helio G91 are clocked at 2.0GHz. This gap in clock speed gives the Helio G91 a slight advantage over the Unisoc T612. As a result, the Helio G91 will run apps, as well as other tasks and play games better than the Unisoc T612.

On AnTuTu v10, the Helio G91 has a score of 271,623 whilst the Unisoc T612 can only reach a peak performance of 245,849. The gap between both SoCs isn't all that wide but that not withstanding, the advantage goes to the Helio G91.

Gaming on the MediaTek Helio G91 vs Unisoc T612

Mobile gaming has grown steadily over the last few years and smartphone games are starting to mature. It is a now a requirement in the mind of many consumers that their phones should play games. This job is facilitated by the GPU on the SoC.

The GPU on the Helio G91 (Mali G52 MP2) is more powerful than the GPU on the Unisoc T618 (Mali G57 MP1). Because of this, the Helio G91 tends to handle graphical tasks and gaming better than the Unisoc T612.

Memory and Storage

The Memory refers to the level of type of RAM that an SoC supports while the storages refers to the type of storage that the SoC also supports. RAM support is important because the SoC needs to support a decent type of RAM inorder to boost ots own performance. In this case, both phones here support the same LPDDR4X RAM. However for storage, the Unisoc T612supports up to UFS 2.2 whilst the Helio G91 is stuck with support for eMMC 5.1.

Faster storage and RAM helps to boost the performance of your SoC which in turn boosts the performance of your smartphone. So in this case, the Unisoc T618 holds an advantage over the Helio G91.

Photography and videography

Both SoCs support cameras of up to 108MP (Megapixels) for photography. This should guarantee some very decent levels of photography. They can also both record and playback Full High Definition (FHD or 1080p) videos at 30fps. Whilst on paper this is a tie, MediaTek Helio SoCs has always held the edge over Unisoc SoCs when it comes to photos and videos so this could be something to keep in mind.


Connectivity generally refers to all the ways that an SoC can connect to the Internet via cellular broadband or WiFi, and to other devices via Bluetooth and WiFi. This is usually facilitated by the network modem on the SoC. In this case, both SoCs are last Gen SoCs so they only support 4G (LTE Cat. 7). They also both support WiFi 5 but the Helio G91 support Bluetooth 5.4 whilst the Unisoc T612 can only support Bluetooth 5.0.

Possible battery life

Both SoCs are built on a 12nm TSMC process and should offer the same levels of battery life, heating and efficiency. However, you should note that battery life is also influenced heavily by other factors such as screen resolution and type, usage patterns and others. You should also note that the 12nm process is not very battery efficient and has been replaced by better fabrication processes.

Conclusion and recommendation

In the end, the Helio G91 is the better SoC but only just. It offers a slightly performance both for apps/tasks and for gaming. It also holds the better Bluetooth support as well however it tends to be a bit more pricey. The Unisoc T612 on the other hand mostly lags behind the Helio G91 in many departments but it is still a solid and more affordable alternative to the Helio G91.
