MediaTek Helio G99

The MediaTek Helio G99 has been a familiar name in budget and mid-range phones since it launched in May 2022, and years later it still shows up in a lot of affordable devices. That staying power says something about how well-balanced this chipset is for everyday use, even if it was never designed to chase flagship-level numbers.

At the center of the MediaTek Helio G99 is an eight-core setup built on a 6nm manufacturing process from TSMC. Two Cortex-A76 cores run at up to 2.2GHz for heavier tasks, while six efficiency-focused Cortex-A55 cores handle lighter background work at up to 2.0GHz. This kind of split matters more than people realize. The powerful cores kick in when you’re opening apps or switching between them quickly, and the smaller cores take over during simpler tasks like checking notifications or browsing, which helps keep power draw down and extends battery life through a normal day of use.

On the graphics side, the chip uses an Arm Mali-G57 MC2 GPU running at 1000MHz, part of the Valhall architecture family. It’s not built for the demanding settings serious mobile gamers chase, but it handles popular titles reasonably well. In real testing, PUBG Mobile ran at 86 FPS on low settings, Shadowgun Legends hit 91 FPS on low, and Genshin Impact managed 48 FPS even on ultra settings. Call of Duty Mobile stayed playable at 37 FPS on ultra, and Mobile Legends held steady around 55 FPS. These numbers point to a processor that’s comfortable with casual and mid-tier gaming rather than the most graphically intense titles.

Memory support comes through LPDDR4X RAM running at 2133MHz, paired with UFS 2.2 storage, and the chipset can address up to 12GB of RAM. That combination is enough for smooth multitasking on a budget phone, letting you jump between apps without much lag, though it won’t match the snappier feel of devices running newer memory standards.

For photography, the MediaTek Helio G99 supports a single 108MP sensor or dual setups up to 16MP each, backed by a triple ISP with AI face detection and multi-frame noise reduction for cleaner shots in tricky lighting. Video tops out at 2K recording, which is modest by today’s standards but fits the mid-range positioning of this chip.

Connectivity is one area where the limits show. There’s no 5G support here, only 4G LTE with download speeds up to 650Mbps, alongside Wi-Fi 5 and Bluetooth 5.2. For anyone specifically shopping for a 5G-ready device, that’s worth keeping in mind.

Benchmark-wise, the Helio G99 posted an AnTuTu 11 score of 552,286 and a GeekBench 6 single-core result of 727, numbers that place it firmly in the mid-range CPU performance tier rather than competing with premium silicon.
