Mediatek Helio G99 vs Unisoc T9100 (T820) vs MediaTek Dimensity 6080
Mediatek Helio G99
► remove from comparison
The Mediatek Helio G99 is a mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2022. It is manufactured in a 6 nm FinFET process and is equipped with 2x big ARM Cortex-A76 cores with up to 2.2 GHz and 6x small and power efficient ARM Cortex-A55 cores (max. 2 GHz) in two clusters (bigLITTLE). The chip integrates an ARM Mali-G57 MC2 (two cores). Compared to the older Helio G96, the G99 is manufactured in the more recent 6nm process and clocks higher.
Furthermore, the integrated LTE / 4G modem supports Cat-13 download speeds. Wi-Fi 5 is also integrated (a/b/g/n/ac). The memory controller supportsLPDDR4x with up to 4,266 Mbps.
Unisoc T9100 (T820)
► remove from comparison
The Unisoc T9100 (formely Unisoc T820) is a mid range SoC for Android based smartphones and tablets. It integrates an octa-core CPU with three clusters. One fast ARM Cortex-A76 clocked at up to 2.7 GHz, three more A76 performance cores clocked at up to 2.3 GHz and a power efficiency cluster of four ARM-Cortex-A55 cores with up to 2.1 GHz. The integrated memory controller supports LPDDR4/4X with up to 2133 MHz (2x 16 Bit). The integrated ISP supports two main cameras and two subsidiary cameras (up to 108 MPix). The integrated graphics card is an ARM Mali-G57 MC4 (4 cores) at up to 850 MHz. Unisoc also specifies that the T9100 offers hardware AI acceleration with up to 8.0 TOPS peak performance of the NPU.
The chip is manufactured on the modern 6nm EUV process.
MediaTek Dimensity 6080
► remove from comparison
The MediaTek Dimensity 6080 (MT6833V/MT6833GP) is an ARM-based SoC (system-on-a-chip) manufactured by TSMC using the 6 nm process. It was specially designed for use in Android smartphones and is in the lower mid-range in terms of performance. It supports all current mobile communication standards, including 5G Sub6.
The SoC is identical to the MediaTek Dimensity 810 the only difference is that the Dimensity 6080 can cope with a camera resolution of up to 108 megapixels.
The CPU works with a total of eight cores, which are divided into two clusters. One has two ARM Cortex-A76 power cores with up to 2.4 GHz each, while the other has six ARM Cortex-A55 energy-saving cores with up to 2.0 GHz each. LPDDR4x RAM with 2,133 MHz can be used as RAM and UFS 2.2 is supported as internal memory.
In terms of connectivity, dual 5G (Sub6) with a theoretical peak download speed of up to 2.77 GBit/s is available, as well as Wi-Fi 5 and Bluetooth 5.1.
The integrated graphics unit ARM Mali-G57 MP2 can power displays with a resolution of up to 2,520 x 1,080 pixels (Full HD+) and a refresh rate of up to 120 Hz.
