https://www.techpowerup.com/306460/amd-hybrid-phoenix-apu-comes-with-performance-and-efficiency-cores According to the latest leak, AMD's upcoming Phoenix accelerated processing units (APUs) could feature a hybrid design, featuring Performance and Efficiency cores. While there are no precise details, the latest AMD processor programming guide, leaked online, clearly marks these as two types of cores, most likely standard Zen 4 and energy-efficient Zen 4c cores. These two set of cores will features a different feature set, and the latest document gives software designers guidelines. Such hybrid CPU design, similar to ARM's BIG.little architecture, will allow AMD to be more competitive with Intel's similar P- and E-core design, allowing it to achieve certain performance levels while also maintaining power efficiency.
Last week, AMD's alleged Phoenix 2 APU has been spotted with such hybrid design, but the recent leak suggest that such similar, or same design, could be coming with AMD Phoenix APUs that are coming this year. AMD's Zen 4c cores were only mentioned with AMD's EPYC "Bergamo" CPUs, so it is quite interesting to see them implemented in other market segments as well.
Looks like AMD will introduce an APU with similar traits to Intel's latest CPUs but with better power efficiency.
