The MediaTek Helio G91 is a 4G chipset with an octa-core CPU, Mali-G52 MC2 graphics, and support for displays up to 90 Hz. Published benchmark results vary by test version and handset: 91mobiles reports AnTuTu 265,150, while NanoReview lists 354,158 in AnTuTu 11. Neither score is a guaranteed result for every Helio G91 phone.
MediaTek Helio G91 specifications
The specifications below are platform capabilities published by MediaTek. They describe what a phone maker can implement, not what every phone using the chip must include.

| Area | Published capability |
|---|---|
| CPU | 64-bit octa-core design using Arm Cortex-A75 and Cortex-A55 cores; maximum frequency of 2 GHz |
| GPU | Arm Mali-G52 MC2, up to 1 GHz |
| Memory | LPDDR4X up to 8 GB, with a listed maximum frequency of 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, BeiDou, and FM radio |
| 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 at the same listed ceilings |
MediaTek also lists electronic image stabilization and rolling-shutter compensation. A phone maker chooses the actual camera sensor and processing pipeline, memory and storage configuration, display, and other hardware, so a phone may offer less than the platform maximum.
Is the Helio G91 a 5G chip?
No. MediaTek lists 4G LTE and earlier connectivity for the Helio G91, including dual 4G VoLTE, but does not list 5G support. Its listed wireless capabilities include Wi-Fi 5 and Bluetooth 5.0. Check a phone’s regional model and supported network bands before buying; chipset capability alone does not establish that a particular handset will work on every carrier.

Helio G91 benchmark scores
Third-party benchmark figures differ. The two sources below report different AnTuTu totals; NanoReview explicitly identifies its total as AnTuTu 11. Treat each result as tied to its source, version, device, software, and sample rather than as a universal chipset score.
| Source and test | Reported result | How to interpret it |
|---|---|---|
| 91mobiles: AnTuTu | 265,150 total: CPU 84,550; GPU 38,034; memory 69,828; UX 72,738 | 91mobiles describes this as the highest recorded score from a device running the Helio G91. It is a publisher-reported result, not a MediaTek guarantee. |
| 91mobiles: Geekbench 6 | 412 single-core; 1,448 multi-core | Publisher-reported scores; the page describes its figures as based on real-world testing of devices using the chip. |
| NanoReview: AnTuTu 11 | 354,158 total | NanoReview also displays dated user submissions and fewer than three samples for some tests. |
| NanoReview: Geekbench 6 | 405 single-core; 1,407 multi-core | Publisher-reported result; some benchmark sample counts shown on the page are fewer than three. |
Do not compare AnTuTu totals as though they came from the same version or test conditions: one source’s stated version is AnTuTu 11, while the other reports an AnTuTu score without identifying that version in the cited listing. The sources also do not establish controlled tests of the same handset under the same conditions.

What benchmark scores can—and cannot—tell you
A benchmark is useful for rough comparisons when the test version and handset are aligned. A score attached to a chipset name does not predict exactly how a specific phone will perform: cooling, software, memory configuration, storage, battery behavior, and sustained workloads can all shape the experience.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Compare results from the same benchmark version and, where possible, the same phone models.
- Check the phone’s RAM and storage configuration, display, battery, cooling design, software, price, and network-band support alongside the processor.
- Do not infer a guaranteed gaming frame rate from these scores. The cited sources do not establish a standardized game test or FPS result for a named Helio G91 phone.
What to expect when choosing a Helio G91 phone
The chip’s listed 4G connectivity, eMMC 5.1 storage, and support for up to 90 Hz displays describe a platform aimed at phones without 5G; they do not by themselves establish a phone’s everyday speed, screen quality, or gaming performance. A 90 Hz panel, 8 GB of memory, or 108 MP camera is not guaranteed simply because the chipset supports those maxima.
