It will work with Cortex-A720 and Cortex-A520
Arm has unveiled the Cortex-X4 supercore, which will be used in the next generation of flagship single-chip systems.
Arm is talking about a 15% performance boost, which is a lot for a single generation. In addition, Cortex-X4 is the most efficient Arm super-core ever.
Interestingly, in the Cortex-X4 press release, most of the text does not refer to the core itself. Arm also unveiled its most powerful CPU cluster ever. This refers to the possibility of combining Cortex-X4 with the new Cortex-A720 and A520 cores.
Arm introduced the Cortex-X4 supercore
The basis of the cluster is the new DynamIQ DSU-120 block, which allows you to cluster 14 processor cores. Of course, this is not required for smartphones, but it is a good start for platforms aimed at PCs. As an example, Arm gives a cluster of 10 Cortex-X4 cores and 4 Cortex-A720. The block also supports L3 cache up to 32 MB and new intelligent power saving modes.
Separately, Arm mentioned a cluster with a core formula of 1 + 5 + 2. It is this configuration that is attributed to the SoC Snapdragon 8 Gen 3.
