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 585 MHz and features an X24 LTE modem supporting Cat 20 uplink and Cat 20 downlink. This chip supports up to 16 GiB of octa-channel LPDDR4X-4266 memory.

Overview[edit]

Block Diagram

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.

Cache[edit]

[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.
