Snapdragon 865 is a high-performance 64-bit ARM system on a chip designed by Qualcomm and introduced in late 2019. Fabricated on TSMC's 7nm (N7P) process, the 865 features four Kryo 585 Silver high-efficiency cores operating at 1.8 GHz along with three high-performance Kryo 585 Gold operating at 2.42 GHz and another prime Kryo 585 Gold core operating at 2.84 GHz. The Snapdragon 865 integrates the Adreno 650 GPU operation at 600 MHz and supports up to 16 GiB of quad-channel LPDDR5-5500 memory.

The Snapdragon 865 is designed to be paired with Qualcomm's X50 5G modem (an external chip) and an RF front-end interface chip (RFFE) to bring 5G NR, sub-6 GHz and mmWave, support.

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.
