The Helio G91 has higher listed CPU clocks, while 91mobiles’ device-tested results show the UNISOC T7250 ahead in AnTuTu and by smaller margins in Geekbench. Those scores are not a controlled chip-only comparison, so the better choice depends on the specific phone’s memory, storage, display, cooling and price.
How the Helio G91 and T7250 differ
Both are 12 nm, 4G smartphone platforms with two Arm Cortex-A75 cores and six Cortex-A55 cores. Their headline differences are clock speeds, graphics hardware, display options and storage support.

| Benchmark | Helio G91 | UNISOC T7250 |
|---|---|---|
| AnTuTu | 265,150 | 381,574 |
| Geekbench single-core | 412 | 441 |
| Geekbench multi-core | 1,448 | 1,480 |
These are 91mobiles’ highest reported device results, accessed October 7, 2026; they are not scores from a controlled chipset-only head-to-head. T7250’s reported AnTuTu total is substantially higher, while the Geekbench differences are much smaller. A phone’s configuration and test conditions can affect scores, so the figures should not be treated as proof that every T7250 phone will outperform every G91 phone. See the 91mobiles Helio G91 page and 91mobiles T7250 page.
What the differences mean in a phone
Everyday CPU performance
The G91’s Cortex-A75 cores have a higher listed maximum clock, 2.0 GHz versus 1.8 GHz. That specification alone does not establish a consistent real-world speed advantage: performance also depends on how a handset manages heat and power, alongside its software and memory configuration.

- 【48MP+20MP+2MP+16MP Camera】Capture every moment with the Ulefone Armor X32's 48MP main camera and 2MP Macro camera. The 20MP night vision camera ensures you can navigate and capture in low-light conditions. The 16MP front camera enhances your selfies, and the underwater mode allows you to take photos and videos underwater, even when swimming or diving.

Graphics and gaming
The chips use different Mali GPU designs, and the G91’s listed GPU clock is higher. Clock speed by itself is not enough to determine which will deliver better performance across games or sustained graphics workloads. Look for tests of the exact handset, especially when gaming for extended periods; the available benchmark figures do not establish frame rates or thermal behavior.

Display and storage options
The T7250’s platform specification pairs HD+ panels with refresh rates up to 120 Hz, or FHD+ at 60 Hz. The G91 supports displays up to 2520 × 1080 at 90 Hz. A high-refresh specification matters only if the phone maker installs a matching panel.

- Memory and storage: Verify RAM capacity, storage capacity and—on a T7250 phone—whether the manufacturer actually uses UFS.
- Screen: Check the shipped resolution and refresh rate, not just the chip’s maximum supported mode.
- Performance evidence: Prefer device tests using the same benchmark version and test protocol. Scores from separate devices and pages are less directly comparable.
- Gaming and heat: Seek handset-specific sustained-load testing rather than inferring game performance from GPU clock figures.
- Ownership factors: Compare the phone’s price, battery, camera implementation, software and update support, and cellular-band support for your region.
For context, 91mobiles identifies the itel S24 as a Helio G91 phone and the realme C100X as a T7250 phone. Those associations do not establish current availability, configuration or price in every market; check the exact regional model before comparing offers.
