Mediatek Helio G99 vs Qualcomm Snapdragon 6s Gen 3
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.
Qualcomm Snapdragon 6s Gen 3
► remove from comparison
The Qualcomm Snapdragon 6s Gen 3 (SM6375) is an ARM-based SoC for smartphones and tablets in the upper mid-range segment. Launched in mid-2024, the chip offers two fast ARM Cortex-A78-based cores with up to 2.3 GHz and 6 ARM Cortex-A55-based power cores with up to 2 GHz.
The design of the chip and the technical data are similar to the older Snapdragon 695. The Qualcomm Snapdragon 6s Gen 3 is manufactured using the older 6 nm technology and has a higher maximum clock rate as well as some new features compared to the 695. As a result, the performance in our tests with the Motorola Moto G85 is also slightly higher than the older Snapdragon 695.
The integrated graphics card is the Adreno 619. The 5G modem called Snapdragon X51 achieves a maximum of 2.5 GBit / 0.8 GBit (download/upload) and supports mmWave. The FastConnect 6200 subsystem offers Bluetooth 5.2 and Wi-Fi 5 (8x8 sounding, dual band, 2x2). All important satellite positioning systems such as GPS, QZSS, GLONASS, SBAS, Beidou and Galileo are supported.
The image signal processor for the cameras supports 3 cameras. Up to 108 megapixels are possible with the main camera and the recording of images in HEIC format is also possible.
