Snapdragon 845 is a high-performance 64-bit ARM LTE system on a chip designed by Qualcomm and introduced in late 2017. Fabricated on Samsung's 10nm 10LPP, the 845 features four Kryo 385 Silver high-efficiency cores operating at 1.7 GHz along with four high-performance Kryo 385 Gold cores operating at 2.8 GHz. The Snapdragon 845 integrates the Adreno 630 GPU operation at 710 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.

Cache[edit]

Quad-core cluster Cortex-A75:
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. |
