MediaTek Helio G91-Ultra Chipset Review — Specifications and Benchmarks
out of 10
MediaTek Helio G91-Ultra represents a slightly upgraded variant of the base Helio G91 chip, aimed at the very budget-tier segment of phones.
CPU
It uses 8 cores: two Cortex-A75 performance cores plus six Cortex-A55 efficiency cores, built on a relatively older 12nm process. Some specialized reviews note that the added "Ultra" suffix isn't matched by significant real performance differences compared to the base variant, a point worth keeping in mind when comparing against rivals.
GPU
The chip uses a Mali-G52 MC2 unit clocked up to 1000MHz in the improved variant, suited to light and medium apps without ambition for heavy gaming performance.
Connectivity and Performance
The chip supports 4G networks only, no 5G. In benchmarks, the base G91 chip scored between 258,000 and 277,000 points on AnTuTu depending on the device, and between 1,339-1,417 on the Geekbench multi-core test.
✅ Pros
- +Suited for light daily use and basic games.
- +Good power efficiency for this price tier.
- +Very low cost suited for very budget phones.
❌ Cons
- −No 5G network support.
- −The real gap over the base variant is limited despite the "Ultra" naming.
- −Relatively older 12nm process compared to newer rivals.
