Overview[edit]
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 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. |
