The MediaTek Helio G91 is a 4G smartphone platform with an octa-core CPU, Mali-G52 MC2 graphics and support for displays up to 90 Hz. Its benchmark scores vary by test version and phone, so no single result is guaranteed across every Helio G91 handset.
MediaTek Helio G91 specifications
The figures below are platform capabilities published by MediaTek. They describe what a phone maker can build around the chip, not features every phone necessarily includes.
| Area | Published specification |
|---|---|
| CPU | 64-bit octa-core Arm Cortex-A75 and Cortex-A55; maximum frequency of 2 GHz |
| GPU | Arm Mali-G52 MC2; listed frequency up to 1 GHz |
| Memory | LPDDR4X, up to 8 GB and 1800 MHz |
| Storage | eMMC 5.1 |
| Display | Up to 2520 × 1080 resolution and 90 Hz refresh rate |
| Cellular | 4G LTE, carrier aggregation, FDD/TDD, LTE Cat-7 downlink and Cat-13 uplink, dual 4G VoLTE |
| Wireless and location | Wi-Fi 5 (802.11 a/b/g/n/ac), Bluetooth 5.0, GPS, GLONASS, Galileo and BeiDou; FM radio listed |
| Camera and video | Support for camera sensors up to 108 MP; H.264 and H.265/HEVC encoding up to 2K at 30 fps or 1080p at 60 fps. H.264, H.265/HEVC and VP9 playback are listed at the same ceilings. |
What the specifications mean in a phone
It is a 4G chip, not a 5G platform
MediaTek lists LTE and earlier cellular technologies for the Helio G91, but does not list 5G support. A phone using it should therefore be considered a 4G model; check the handset’s supported LTE bands against your carrier and region.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsMaximum support is not a promise about every handset
The chip can support up to 8 GB of LPDDR4X and a 90 Hz, 2520 × 1080 display, but a manufacturer chooses the actual memory amount, panel resolution and refresh rate, camera sensor, and storage configuration. Likewise, support for a 108 MP sensor does not mean a G91 phone has a 108 MP camera or will produce images of a particular quality.

How to compare a Helio G91 phone
- Compare benchmark scores only when they use the same benchmark version; check the tested phone and sample information where available.
- Check the specific handset’s RAM, storage, display, camera hardware and LTE bands rather than assuming the platform maximums are present.
- For everyday speed or gaming, consider the whole phone, including its software, battery and cooling design. The cited sources do not establish a standardized game frame-rate result for a named G91 handset, so a guaranteed FPS or claim that every game runs smoothly is not supported.
- Compare the actual phone’s price and availability in your region; chipset specifications alone do not establish value.
Example phone with the Helio G91
91mobiles lists the Itel S24 as a phone powered by the Helio G91. Confirm the exact regional model and chipset in a current product listing before buying, since availability and specifications can vary by market.
