Snapdragon 855 Plus (855+) is a high-performance 64-bit ARM LTE system on a chip designed by Qualcomm and introduced in mid 2019. Fabricated on TSMC's 7nm process, the 855+ features four Kryo 485 Silver high-efficiency cores operating at 1.8 GHz along with three high-performance Kryo 485 Gold operating at 2.42 GHz and another higher-performance Kryo 485 Gold core operating at 2.84 GHz. The Snapdragon 855 integrates the Adreno 640 GPU operation at 700 MHz and features an X24 LTE modem supporting Cat 20 uplink and Cat 20 downlink. This chip supports up to 16 GiB of quad-channel LPDDR4X-4266 memory.

The Snapdragon 855+ can 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.

The 855+ is identical to the 855 but features slightly higher GPU and CPU frequencies.

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.
