Exynos 990 is a 64-bit octa-core ARM high performance mobile system on a chip designed by Samsung and introduced in 2020. The processor is fabricated on Samsung's 7nm EUV FinFET process and features 8 cores in a tri-cluster configuration consisting of 2 Mongoose 5 big cores, 2 Cortex-A76 middle cores, and 4 Cortex-A55 little cores. This chip supports up to 12 GiB of quad-channel 16-bit LPDDR5-5500 memory and incorporates a Mali-G77 MP11 GPU. The 990 is designed to go along with Exynos Modem 5123 5G modem.

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.
