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 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 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.
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 Plus is an identical, but higher clocked version of this processor.

Clock domains[edit]
- See also: TSMC 7-nanometer (N7) process technology
The Snapdragon 855 utilizes TSMC 7-nanometer process. One of the major changes Qualcomm has done compared to the Snapdragon 845 is on the physical implementation side. Whereas the Snapdragon 845 uses two clock domains in a standard DynamIQ cluster - one for the Silver cores and one for the Gold cores, the 855 uses three clock domains. One of the cores from the prior quad-core Gold clock domains has been moved to its own clock domain. Qualcomm refers to that core as a 'Prime' core. The Prime core utilizes TSMC high-performance cell (which uses a slightly relaxed 64 nm poly pitch) while the rest of the SoC utilizes TSMC standard high-density cells. The use of the high-performance cells allows for the slightly higher frequency at similar power.
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%. Check New Qualcomm Snapdragon 8 gen 1 vs A15 Bionic Comparison

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. |
