MediaTek added two additional products to its premiere deca-core SoC family today. The Helio X23 and X27 join the previously released Helio X20 and X25, adding additional performance levels for OEMs to choose from.

All four SoCs use the same deca-core CPU configuration—two ARM Cortex-A72 cores for heavy workloads that require higher performance and two quad-core Cortex-A53 clusters, using different DVFS curves, for medium to light workloads where lower-power operation is desirable. MediaTek’s custom-developed, power-aware scheduler, CorePilot 3.0, still handles thread distribution. The differentiating factor is clock frequency, with peak frequencies increasing from 2.1GHz / 1.85GHz / 1.4GHz (A72 / A53 / A53) for the X20 to 2.6GHz / 2.0GHz / 1.6GHz for the new X27. The ARM Mali-T880MP4 GPU runs at up to 780MHz in the X20 and X23 and up to 850MHz in the X25. The new X27 bumps the GPU frequency even higher to 875MHz, just shy of the 900MHz peak frequency used by HiSilicon’s Kirin 950/955 that also uses a Mali-T880MP4 GPU.
