Snapdragon 8cx (Snapdragon 8 Compute eXtreme) 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 8cx features four Kryo 495 Silver high-efficiency cores operating at 1.8 GHz along with four high-performance Kryo 495 Gold operating at 2.84 GHz. The Snapdragon 8cx integrates the Adreno 680 GPU operation at ? MHz and features an X24 LTE modem supporting Cat 20 uplink and Cat 20 downlink. This chip supports up to ? GiB of octa-channel LPDDR4X-4266 memory.

The Snapdragon 8cx was announced by Qualcomm on December 6, 2018. The chip is what Qualcomm considers a new high tier Snapdragon aimed at always-connected PCs with higher performance and thermal headroom over traditional smartphone devices. The chip comprise of a quad-core cluster of Kryo 495 Gold (Cortex-A76) big cores and a quad-core cluster of Kryo 495 Silver (Cortex-A55) little cores.

[Edit/Modify Cache Info]

hierarchy icon.svg
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.
