Template:mpu Helio P25 (MT6757T) is a 64-bit octa-core ARM LTE system on a chip designed by MediaTek and launched in 2017. This SoC, which incorporates eight Cortex-A53 cores and is manufactured on TSMC's 16 nm process, operates at up to 2.5 GHz and supports dual-channel LPDDR4-1600. This chip incorporates the Mali-T880 IGP operating at 1 GHz. This SoC has a modem supporting LTE User Equipment (UE) category 6.

The Helio P25 is identical to the Helio P20 apart from the higher clock speeds for both the CPU and GPU.

Cache

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.
