MediaTek Dimensity 1080 vs Mediatek Helio G99

MediaTek Dimensity 1080

The Mediatek Dimensity 1080 is a mid-range ARM SoC (system-on-a-chip) that can be used in both smartphones and tablets (mainly Android). The SoC integrates two ARM Cortex-A78 cores with up to 2.6 GHz for demanding tasks and six power-saving ARM Cortex-A55 cores with clock rates of up to 2 GHz.

The chip has an integrated sub-6 GHz 5G modem including dual-SIM support that can reach a maximum download speed of up to 2.77 Gbit/s. Wi-Fi 6 (802.11ax) is supported as well as Bluetooth 5.2.;

The memory controller copes with LPDDR4x or LPDDR5 working memory as well as UFS 3.1 mass storage. As an integrated graphics card, the SoC uses the ARM Mali-G68 MC4, which supports displays with 120 Hz as well as HDR10+ at a maximum resolution of 2,520 x 1,440 pixels.

The differences to the Dimensity 920 are minor, only the slightly higher maximum clock and a support for higher-resolution cameras can be found.

The MediaTek Dimensity 1080 is still manufactured in 6 nm.

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.
