AMD will publish the clock speeds of the AMD Zen 4c cores 'within a few weeks'

AMD last month unveiled the Zen 4c microarchitecture intended for its mobile Ryzen processors, starting with the Ryzen 5 7545U, Ryzen 3 7440U and the Ryzen Z1. However, some specifications were left in the dark at the unveiling. For example, it was mentioned that the regular Zen4 cores have a higher absolute clock speed limit, but the precise speeds of the CPUs that use the Zen 4c microarchitecture were not mentioned.

Tom’s Hardware found that not only were clock speeds not listed, but the processors’ main spec pages don’t even mention that they run (partially) on the smaller and lower-performance Zen 4c cores. To find out if and how many of these cores are present, consumers must search the list of all specifications, although this list is not present on many retailers’ product pages. In marketing materials for the Ryzen 5 8540U and Ryzen 3 8440U, the presence of these cores is also omitted. According to the site, this smacks of misleading marketing practices, so it decided to contact AMD.


The general specifications state how many cores the CPU has, but not what type of cores

The chip manufacturer promises in a response that it will reveal the clock speeds of the Zen 4c cores ‘soon’. In addition, the main specification pages of the Ryzen CPUs should also state whether and how many Zen4c cores are present. However, AMD states that it will take ‘a few more weeks’ to implement these changes to its website.
