If you’re out shopping for a budget smartphone, chances are high that you’ll run into the Unisoc T7250 or the MediaTek Helio G99. These two chips are powering many of the phones you’ll see in sub-₦200K or even ₦300K devices in Nigeria right now. But what happens when we compare them head-to-head? That’s what we’re doing today in this Unisoc T7250 vs Helio G99 face-off.
On paper, these two chips look like they have a lot in common — both are 4G-only, both support up to 108MP cameras, and both sit somewhere in the budget-to-lower-midrange category. But real-world performance tells a different story. Let’s take a proper look.
Unisoc T7250
The Unisoc T7250 is another chapter in Unisoc’s long-standing habit of recycling chips with new names. It’s a rebadged Unisoc T615, which was launched in 2024. The T7250 is designed to power budget smartphones that need to stay affordable without completely sacrificing performance.
Built on TSMC’s 12nm FinFET process, the T7250 has a 2+6 core setup: two Cortex A75 performance cores running at 1.8GHz and six Cortex A55 efficiency cores running at 1.6GHz. It uses a Mali-G57 MP1 GPU, which is a pretty modern GPU for this class, though performance is limited due to its single-core configuration.
You’ll find the T7250 in ultra-budget phones like the Redmi A5 4G, Itel City 100 and various other entry-level devices.
MediaTek Helio G99
The Helio G99, on the other hand, was released by MediaTek in mid-2022 as a 4G-focused SoC with a strong emphasis on gaming. It was introduced as the successor to the Helio G96, improving performance and power efficiency with a 6nm TSMC process.
This chip is no slouch. It brings in two Cortex A76 cores at 2.2GHz and six Cortex A55 cores at 2.0GHz. For graphics, you get the Mali-G57 MP2, which is more powerful and better equipped for gaming and multimedia tasks.
It’s used in phones like the Redmi Note 13 4G, Tecno Pova 5, Infinix Note 30, Realme Narzo N53, and even some affordable Honor and Vivo phones. It’s a popular choice among OEMs because it hits that sweet spot between cost and performance.

⚙️ CPU Performance
Let’s start with the most obvious difference: the CPU. The T7250 is using Cortex A75 cores, which is a whole generation behind the A76 cores found in the G99. Even worse, the A75s are running at only 1.8GHz, whereas the G99’s A76s are clocked at 2.2GHz.
The six Cortex A55 efficiency cores are also faster on the G99 (2.0GHz) than on the T7250 (1.6GHz). In both GeekBench and real-world use, this translates to more CPU power, better multitasking, and overall smoother performance from the G99.
Verdict: Helio G99 wins easily.
🎮 GPU and Gaming
The GPU situation follows a similar pattern. Both chips use Mali-G57, but the T7250 has the MP1 variant while the G99 uses MP2. That means the G99 has two shader cores instead of one, offering nearly double the throughput.
If you like playing eFootball, PUBG, Free Fire, or even lighter 3D games like Dream League Soccer, the G99 is simply better suited. It handles mid-to-high graphics settings more comfortably and drops fewer frames. The T7250 on the other hand will handle mid-to-low graphics settings.
Verdict: G99 wins again.
🧠 Benchmarks
We’ve already touched on benchmarks, but let’s put them side by side.
- AnTuTu 10:
- T7250 scores ~263K
- G99 scores ~422K
- GeekBench 6:
- T7250: 441 (single core), 1454 (multi-core)
- G99: ~550 (single core), ~2000 (multi-core)
The performance difference is not subtle. It’s very clear that the G99 outpaces the T7250 by quite a margin, especially when multitasking or handling heavy apps.
Verdict: G99 wins clearly.
📦 RAM & Storage
Here, both chips support UFS 2.2, which is fast enough for budget phones. But the RAM story is a bit different.
- T7250 supports LPDDR4X at 1866MHz
- G99 supports LPDDR4X at 4266Mbps
The G99 allows for higher memory bandwidth, which means faster multitasking and smoother performance when switching apps.
Verdict: Another win for G99.
📺 Display Support
This one is more situational.
- The T7250 can push 720p at 120Hz or 1080p at 60Hz. That makes it good for smoother displays, especially on low-res screens.
- The G99 supports 1080p panels but doesn’t officially mention high refresh rates. However, in practice, we’ve seen G99 phones with 90Hz and even 120Hz displays (like the Infinix Note 30).
Verdict: Slight edge to G99 for FHD quality, but T7250 isn’t bad if paired with a 720p 90Hz panel.
📸 Camera and Video
Both chips support 108MP cameras and 1080p@60fps video recording. They also have support for multi-camera setups. The main difference would come from how OEMs implement the ISP (Image Signal Processor) on each phone.
Still, since the G99 is more powerful and newer, you can expect slightly better image processing and AI enhancements in real use.
Verdict: G99 takes the edge.
📶 Connectivity
Both processors are 4G-only, support dual VoLTE, and offer WiFi 5 and Bluetooth 5.2. No real difference here.
Verdict: Draw.
🧾 Conclusion: Which One Should You Pick?
Let’s not sugarcoat it. The Unisoc T7250 is a budget chip meant for basic tasks — WhatsApp, YouTube, calls, and a bit of casual gaming. It’s meant for people who just need a phone that works.
But the Helio G99? That’s in a whole other league. It’s what we call a “lower mid-range” SoC for 4G phones. It offers stronger CPU and GPU performance, faster RAM, better gaming, and stronger multitasking across the board.
Verdict:
If you’re choosing between T7250 vs Helio G99, go with the G99 every single time. It’s simply the better chip in almost every category.
