Helio P15 (MT6755T) is a 64-bit octa-core ARM LTE system on a chip designed by MediaTek and introduced in early-2016. This SoC, which incorporates eight Cortex-A53 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 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 Cortex-A53 with four cores each linked together via a 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.

Cache[edit]

Main article: Cortex-A53 § Cache

[Edit/Modify Cache Info]

Cache Organization

Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
