Mediatek Helio G99 vs Qualcomm Snapdragon 690 5G

Mediatek Helio G99

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.

Qualcomm Snapdragon 690 5G

The Qualcomm Snapdragon 690 5G (SD690) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. It features 8 Kryo 560 called cores (64-Bit capable) that are divided in two clusters. A fast cluster of two cores with up to 2 GHz and  based on the ARM Cortex-A77 design. And a power saving efficiency cluster with up to 1.7 GHz and based on much smaller ARM Cortex-A55 cores. Both clusters can also used together.

In addition to the 8 CPU cores, the SoC integrates a lower mid range Adreno 619L GPU, a X51 5G radio (up to 2.5 Gbits download, no mmWave), a 802.11ax (Wi-Fi 6, 8x8 sounding, WPA3, Dual Band, 2x2), a Bluetooth 5.1 radio, satellite positioning (GPS, QZSS, GLONASS, SBAS, Beidou and Galileo) and a video engine (support for H.265, H.264, VP8 and VP9).

Performance

Due to the two big A77 cores, the performance of the SoC in our benchmarks is on par with mid range SoCs like the Snapdragon 765 or the Dimensity 800U.

The Snapdragon 690 is produced in the 8nm LPP (Low Power Plus) process at Samsung.
