AMD Zen 4 vs. Zen 4C Performance, Zen 4C Core Scaling With Ryzen 5 8500G
It would be very interesting if AMD were to release a low-power APU featuring all Zen 4C cores as it could be quite interesting for SOHO servers, inference at the edge, etc.
When taking the geometric mean of all the performance benchmarks carried out, the combination of one Zen 4 and one Zen 4C core was around 84% the speed of two Zen 4 cores -- not bad at all for the Zen 4C showing especially with it topping out at 3.7GHz rather than 5.0GHz.
Here is a look at the CPU power consumption over the entire duration of the benchmarking. Enabling each additional Zen 4C core of the Ryzen 5 8500G was increasing the power consumption 2~3 Watts on average.
Lastly for reference purposes is the CPU thermals for all tested core configurations of the Ryzen 5 8500G.
