MediaTek Helio G99 vs MediaTek Dimensity 930: Full Comparison
Introduction
When evaluating smartphones, the system-on-chip (SoC) is a critical component that dictates performance, efficiency, and feature support. MediaTek’s Helio G99 and Dimensity 930 are two 4G processors found in a variety of mid-range and budget-friendly devices. This comparison aims to break down their technical specifications, architectural differences, and typical use cases to help you understand which chipset might align better with different user needs, without focusing on any specific phone model.
Performance & CPU Architecture
The core architecture and manufacturing process are fundamental to a chipset’s performance and efficiency.
- MediaTek Helio G99: Built on a 6nm manufacturing process, it features an octa-core CPU with two ARM Cortex-A76 performance cores clocked at up to 2.2GHz and six ARM Cortex-A55 efficiency cores at up to 2.0GHz. This configuration is designed for balanced everyday tasks and gaming.
- MediaTek Dimensity 930: Also fabricated on a 6nm process, it utilizes a newer CPU configuration: two ARM Cortex-A78 performance cores (up to 2.2GHz) and six ARM Cortex-A55 efficiency cores (up to 2.0GHz). The Cortex-A78 cores provide a noticeable uplift in performance per clock cycle compared to the A76 cores in the G99.
While both chipsets share a similar core count and process node, the Dimensity 930’s more modern A78 cores typically give it an advantage in more demanding applications and multitasking scenarios.
Graphics & Gaming (GPU)
The GPU handles visual rendering, which is crucial for gaming and smooth UI animations.
- MediaTek Helio G99: Equipped with an ARM Mali-G57 MC2 GPU. This is a capable GPU for its class, supporting mainstream mobile games at moderate settings and refresh rates.
- MediaTek Dimensity 930: Integrates an IMG BXM-8-256 GPU. The performance between these GPUs can vary by title and optimization, but the Dimensity 930’s GPU is generally positioned to handle graphically intensive tasks slightly better, often supporting higher graphical fidelity in games.
Both chipsets include gaming-centric features like MediaTek’s HyperEngine technologies to optimize resource management and connectivity during gameplay.
Camera & Multimedia Support
The image signal processor (ISP) defines the camera capabilities a chipset can support.
- MediaTek Helio G99: Features a triple-ISP that can support camera configurations up to a 108MP single sensor. It allows for dual-camera setups with 16MP + 16MP sensors simultaneously. Video capture is typically capped at 1080p resolution.
- MediaTek Dimensity 930: Comes with MediaTek’s Imagiq 750 ISP, which supports camera sensors up to 108MP. It can handle dual-camera setups with 20MP + 20MP sensors. A key differentiator is its support for video recording at up to 4K resolution, which the Helio G99 lacks.
The Dimensity 930 generally offers more advanced multimedia features, including 4K video capture and potentially better AI-enhanced photography capabilities.
Connectivity & Network Support
This is a primary area of differentiation between these two platforms.
- MediaTek Helio G99: This is strictly a 4G LTE chipset. It does not have an integrated 5G modem. It supports standard modern Wi-Fi and Bluetooth standards.
- MediaTek Dimensity 930: Despite its performance tier, the Dimensity 930 includes an integrated 5G modem, supporting sub-6GHz 5G networks. This makes it future-proof in regions with expanding 5G coverage. It also often supports slightly newer versions of Wi-Fi and Bluetooth.
The inclusion of 5G is the most significant practical difference, making the Dimensity 930 relevant for users who have or plan to access 5G networks.
Display & Memory Support
These specifications influence the type of screens and RAM a device can use.
- MediaTek Helio G99: Supports displays with refresh rates up to 120Hz at Full HD+ (2520 x 1080) resolution. It is compatible with LPDDR4x RAM and UFS 2.2 storage.
- MediaTek Dimensity 930: Can drive displays with refresh rates up to 120Hz at Full HD+ resolution. It supports faster LPDDR5 RAM and UFS 3.1 storage, which can lead to quicker app loading and better overall system responsiveness.
The support for LPDDR5 RAM and UFS 3.1 storage gives the Dimensity 930 a potential advantage in memory bandwidth and storage speeds.

Frequently Asked Questions (FAQ)
What is the main difference between the Helio G99 and Dimensity 930?
The most significant difference is network connectivity: the Dimensity 930 has an integrated 5G modem, while the Helio G99 is a 4G-only platform. The Dimensity 930 also typically features a more modern CPU architecture (Cortex-A78 vs. A76) and supports faster memory and storage standards.
Which chipset is better for gaming?
The Dimensity 930 generally offers better gaming potential due to its more powerful CPU cores and GPU. However, the Helio G99 is also designed with gaming in mind and can handle many popular titles well at standard settings. The actual gaming experience also depends heavily on the device’s cooling, software optimization, and display.
Can a phone with a Helio G99 record 4K video?
Typically, no. The Helio G99’s image signal processor is designed to support video capture up to 1080p resolution. For 4K video recording, you would generally need a device equipped with the Dimensity 930 or a similar chipset that explicitly supports 4K encoding.
Is the Dimensity 930 always better than the Helio G99?
Not necessarily in all contexts. While the Dimensity 930 has superior technical specifications, devices using the Helio G99 can often be found at more accessible price points.
