September 11, 2023 at 5:15 p.m. by Andreas Link – According to a die shot, Zen 4c is said to have around 35 percent less chip area than a comparable Zen 4 core. The more economical cores are part of AMD’s heterogeneous design, which is currently coming onto the market primarily as the Phoenix (Ryzen 7000).
While Intel is using two different architectures in its hydride design, AMD, simply put, wants to try shrunken Zen 4 cores. A die shot has appeared for Zen 4c that visualizes the core area, which is around 35 percent less than the normal cores. The image shared by HXL on Unlike Intel, AMD’s small cores also support SMT.

Zen 4c Die Shot: ~35% less area per core (2) Source: via HXL
The monolithic APU design saves on the cache, among other things. While Zen 4 can access 4 MiB of L2 cache, Zen 4c has to make do with 2 MiB. But there are reductions everywhere, including the GPU, which can have up to 4 compute units of the RDNA 3 architecture. We discussed the CPU configuration some time ago; it has lower core voltage and lower clock speeds. Since the C cores do not deviate extremely from the normal ones, AMD can move tasks between the cores with less effort.
The processors are primarily aimed at mobile devices and environments where economical work is a priority. Models for desktop systems are expected to come onto the market at the end of 2023, which will then probably range from 35 to 65 watts and fit into the AM5 socket. You can currently check out the technology in the Lenovo Yoga Slim 7 Gen 8. Handheld consoles that use the heterogeneous Ryzen have also been announced.
