'''Snapdragon 855''' is a high-performance {{arch|64}} [[ARM]] [[LTE]] [[system on a chip]] designed by [[Qualcomm]] and introduced in late [[2018]]. Fabricated on [[N7|TSMC 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 {{qualcomm|Adreno 640}} [[GPU]] operation at 585 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.

Qualcomm reported that at the same power, Clock2 CPUs have improved by roughly 20% from the SDM845 to the SDM855. With the addition of Clock3, the four cores collectively extend this performance gain over the quad-core cluster on the 845 to over 30%.
