Zen 4c is a variant of Zen 4 featuring smaller Zen 4 cores with lower clock frequencies, power usage, reduced L3 cache per core, and is intended to fit a greater number of cores in a given space. Zen 4c's smaller cores and higher core counts are designed for heavily multi-threaded workloads such as cloud computing .
Furthermore, Zen 4 Cloud (a variant of Zen 4), abbreviated to Zen 4c, was also announced. Zen 4c is designed to have significantly greater density than standard Zen 4 while delivering greater power efficiency. This is achieved by redesigning Zen 4's core and cache to maximise density and compute throughput.
