'''Helio P15''' ('''MT6755T''') is a {{arch|64}} [[octa-core]] [[ARM]] [[LTE]] system on a chip designed by [[MediaTek]] and introduced in early-[[2016]]. This SoC, which incorporates eight {{armh|Cortex-A53|l=arch}} cores and is manufactured on [[TSMC]]'s [[28 nm process]], operates at up to 2.2 GHz and supports up to 4 GiB of single-channel LPDDR3-1866 memory. This chip incorporates the {{imgtec|Mali-T880}} [[IGP]] operating at 800  MHz. This SoC has a modem supporting [[LTE]] User Equipment (UE) category 6.

This processor is made of two independent clusters of {{armh|Cortex-A53|l=arch}} with four cores each linked together via a {{armh|CCI-400}}. The two clusters have a maximum operating frequency of 2.2 GHz and 1.2 GHz respectively.

The Helio P15 is identical to the {{\\|Helio P10}} with higher clock speeds for both the GPU and CPU.
