Snapdragon 855 is a high-performance 64-bit ARM LTE system on a chip designed by Qualcomm and introduced in late 2018. 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 ? 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.
