Mediatek Helio G99 vs MediaTek Dimensity 1100
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.
MediaTek Dimensity 1100
► remove from comparison
The Mediatek Dimensity 1100 is a fast mid-range SoC with an integrated 5G modem. It includes four fast ARM Cortex-A78 cores at up to 2.6 GHz and four power efficient Cortex-A55 cores at up to 2 GHz (Octa-Core with Heterogeneous Multi-Processing). Furthermore, the chip integrates a 9 core ARM Mali-G77 MC9 GPU, a Wi-fi 5 modem, a LPDDR4x memory controller, a AI processing unit (APU 3.0 with 6 cores) and video de- and encoding. As one of the first SoCs, the Dimensity 1000 series offers AV1 hardware decoding. The chip is manufactured in the modern 7nm process and should be very power efficient.
