Exynos 8 Octa (8890) is a 64-bit octa-core high-performance mobile SoC designed by Samsung and introduced in early 2016 for their consumer electronics. Manufactured on Samsung's 2nd generation 14 nm process, the 8890 features eight cores consisting of a big quad-core cluster operating at 2.3 GHz with a turbo of up to 2.6 GHz based on Samsung's custom Mongoose 1 microarchitecture and another little quad-core cluster operating at 1.6 GHz consisting of Cortex-A53 cores. This chip supports up to 4 GiB of dual-channel 32-bit LPDDR4-3600 memory and incorporates a Mali-T880 MP12 GPU operating at 650 MHz. The 8890 incorporates an LTE modem supporting cat 12 download and cat 13 upload.

Overview

The Exynos 8 Octa is the first microprocessor that includes Samsung's first custom cores based on the Mongoose 1 microarchitecture. Those cores are said to provide over 30% higher performance and 10% lower power compared to the Exynos 7 Octa. The chip features two quad-core clusters. The first one is the high-performance Mongoose 1 core cluster and a second low-power Cortex-A53 core cluster. Communication is done over Samsung's cache-coherent Coherent Interconnect (SCI).

[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.
