The MediaTek Helio G99 is an eight-core, 6nm-class smartphone chipset for 4G phones—not a 5G processor. Its CPU combines two Cortex-A76 cores clocked up to 2.2GHz with six Cortex-A55 cores. Benchmark scores vary by test version and handset, so a score describes a particular test and sample, not every Helio G99 phone.
Helio G99 specifications at a glance
| Specification | MediaTek-stated capability |
|---|---|
| Manufacturing process | TSMC N6, described as 6nm-class |
| CPU | Eight cores: 2 Arm Cortex-A76 cores up to 2.2GHz and 6 Arm Cortex-A55 cores |
| Graphics and gaming | Mali-G57-class graphics and HyperEngine 2.0 Lite |
| Memory | Up to 2,133MHz |
| Display | Full HD+ resolution up to 120Hz, with Intelligent Display Sync |
| Camera support | Up to 108MP camera; infographic also lists 16+16MP dual-camera support with zero-shutter-lag |
| Mobile network | Integrated 4G LTE, LTE-A Cat-13 downlink and dual 4G VoLTE |
These are platform capabilities, not promises about every phone. The handset maker chooses components and configurations, including memory, display, camera sensors and cooling. MediaTek describes HyperEngine 2.0 Lite features such as resource management and concurrent call/data and Wi-Fi/LTE connections; those vendor descriptions are not independent performance measurements. MediaTek’s Helio G99 specifications and its 2022 Helio G99 infographic list these capabilities.
What benchmark scores does the Helio G99 get?
There is no single definitive Helio G99 benchmark score. Published results differ with the benchmark version, device, RAM, cooling and software. The figures below are database results, not MediaTek-certified guarantees.
| Source and test | Reported result | How to read it |
|---|---|---|
| NanoReview, Geekbench 6 | 727 single-core; 2,047 multi-core | Scores displayed on its living database page, accessed October 7, 2026. |
| NanoReview, AnTuTu 11 | 554,590 total | Score displayed on its living database page, accessed October 7, 2026. |
| NanoReview, AnTuTu 12 | 638,604–699,734 | Range among visible user-submitted results dated September 24–27, 2026; a changing sample, not a controlled chip-wide result. |
| Notebookcheck, Geekbench 6.7 multi-core | 1,964 average; 1,784 minimum; 2,088 maximum | Average and range across devices listed in its database, accessed October 7, 2026. |
| Notebookcheck, AnTuTu v10 | 403,419 average; 383,511 minimum; 422,936 maximum | Average and range across devices listed in its database, accessed October 7, 2026. |
| 91mobiles, AnTuTu | Around 380,698 | The page describes this as its highest recorded result among tested devices. |
| 91mobiles, Geekbench | 575 single-core; 1,766 multi-core | Figures shown on its page; results reflect its tested devices and methodology. |
Do not compare these numbers as though they came from the same benchmark release or test conditions. NanoReview, Notebookcheck and 91mobiles report different versions, samples and methodologies. Their pages provide additional context: NanoReview’s Helio G99 benchmarks, Notebookcheck’s device results and 91mobiles’ tested figures.

What do the specs and scores mean for a phone?
The two Cortex-A76 cores provide the higher-performance part of the CPU, while six Cortex-A55 cores handle lighter work. The core count and clock speed alone do not determine how fast a particular phone feels: memory configuration, thermal design, software and the workload also matter.
Likewise, support for a 120Hz Full HD+ display or a camera up to 108MP does not mean every G99 handset includes those components, nor does a higher supported camera resolution establish image quality. These are ceilings manufacturers may use when designing a phone.

The G99 is a 4G LTE platform. Its listed LTE-A Cat-13 capability and dual 4G VoLTE do not make it a 5G chipset. Check the exact phone model and regional specification if network support matters, since phone variants can differ.

- Benchmark name and version, and whether the result is an average, a single device score or a best recorded result.
- RAM and storage configuration, since phones sold under the same model family can differ.
- Cooling and sustained performance, not only a short benchmark run.
- Software version, display, battery and the price of the exact regional model.
Notebookcheck’s device listings include the Samsung Galaxy A15 as one example of a phone using the Helio G99. That phone is an example only; its results and features should not be assumed to represent every G99 handset.
