Snapdragon 850 is a high-performance 64-bit ARM LTE system on a chip designed by Qualcomm and introduced in mid-2018. Fabricated on Samsung's 10nm LPP process, the 850 features four Kryo 385 Silver high-efficiency cores operating at ? GHz along with four high-performance Kryo 385 Gold operating at 2.96 GHz. The Snapdragon 850 integrates the Adreno 630 GPU operation at ? MHz and features an X20 LTE modem supporting Cat 13 uplink and Cat 18 downlink. This chip supports up to 8 GiB of quad-channel LPDDR4X-3733 memory.

Overview

Positioned as a replacement for the 845 for always-connected ARM-based PCs and fabricated on Samsung's second-generation 10LPP process, the 850 is for the most part a higher-binned version of its predecessor. The chip features four high-performance cores based on the Cortex-A75 microarchitecture and four low-power cores based on the Cortex-A55 microarchitecture. This chip incorporates the X20 LTE modem, supporting Cat 18 up to 1.2 Gbps download and Cat 13 up to 150 Mbps upload.

[Edit/Modify Cache Info]

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.
