Exynos 9825 is a 64-bit octa-core ARM high performance mobile system on a chip designed by Samsung and introduced in mid-2019. The processor is fabricated on Samsung's 7nm EUV (Extreme Ultra Violet) FinFET process and features 8 cores in a tri-cluster configuration consisting of 2 Mongoose 4 big cores and 2 Cortex-A75 middle cores and 4 Cortex-A55 little cores. This chip supports up to 12 GiB of quad-channel 16-bit LPDDR4X-3600 memory and incorporates a Mali-G76 MP12 GPU. The 9825 incorporates an LTE modem supporting cat 20 download and upload.

[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.
