AMD hybrid “Phoenix” APUs to feature Performance and Efficiency cores

AMD Phoenix with Performance and Efficiency cores

The company now has a name for its hybrid design cores in consumer APUs.

According to the AMD Processor Programming Reference (PPR) guide for AMD Family 19h Model 70h CPUs (AMD Zen4/Phoenix), the hybrid architecture may support two types of cores: Performance and Efficiency.

Those names are very similar to what Intel uses for their hybrid design (Performance/Efficient Cores). This also indicates that hybrid architecture is coming to consumer CPU space. What should be noted is that the naming in the programming guide may not necessarily reflect the name that will be used for marketing purposes.

Rumors are pointing towards a possible Phoenix 2 APU design with a hybrid design featuring 2 Performance and 4 Efficiency cores.  Such hybrid architectures will allow AMD to offer more efficient designs for lightweight and battery-powered products, such as low-power gaming consoles.

Thus far, AMD plans for more efficient core types have only revolved around cloud computing with Zen4c architecture. Such type of core is now planned for a new EPYC series codenamed “Bergamo”.
