We know not from today that AMD at some point will focus not only on the most efficient cores, but also on more energy-efficient ones. Intel bet on such a project first on the occasion of mobile Lakefield systems, and then (already on a large scale) in the 12th generation of Alder Lake and newer, which have already debuted on the market or will only debut. AMD, in turn, intends to introduce EPYC Bergamo server systems with 128 Zen 4c cores this year, which are an energy-saving version of the current Zen 4 cores. It seems that in the coming months there will be consumer processors using a similar idea.

According to AMD documentation, there will be new processors in the APU Phoenix series, using two types of cores: Performance and Efficiency.

A fragment of the internal AMD PPR (AMD Processor Programming Reference) documentation for the “Family 19th Model 70h A0” family, which is the equivalent of the Phoenix APU with Zen 4 cores, has appeared on the web. The materials show that some APU systems (which may also be referred to as Phoenix , but also as Phoenix 2, which was mentioned some time ago) will be equipped with two types of cores: Performance Core and Efficiency Core. The former are, of course, the strongest cores, the latter type is designed to improve multi-thread performance while maintaining high energy efficiency.

If you stick with the Phoenix series of APUs, there is an option to combine the classic Zen 4 cores with their more energy-efficient Zen 4c version. According to unofficial information, hybrid AMD Ryzen processors from the Phoenix (2) family would debut no earlier than in the second half of the year, and rather only after the holidays. Their design would have in turn, be based on two Performance cores and four Efficiency cores. Unlike Intel’s solution, AMD’s energy-saving Efficiency cores would also support multithreading. The hybrid architecture should also be an integral part of the next generation of APUs – Strix Point – where we would get high-performance Zen 5 cores and energy-efficient Zen 4c.
