AMD Allegedly Testing Hybrid Processor with Zen 4 and 4c Cores
An unannounced AMD processor identified as Family 25 Model 120 Stepping 0 recently Milky Way @ Home database. A CPU can process 12 threads simultaneously, and CPU Expert @InstLatX64 believes this is AMD’s codenamed Phoenix 2 processor, featuring two high-performance Zen 4 cores and four energy-efficient Zen 4c cores.
AMD Eng sample processor marked 100-000000931-21_N [Family 25 Model 120 Stepping 0] has 12 logical cores (that is, 6 physical cores with simultaneous multithreading) and reports about 1MB of cache. This listing by itself does not prove that we are dealing with AMD’s hybrid Phoenix 2 processors with core configs like Big.Little, but his 6 physical/12 logical cores with an unknown CPU are , suggesting that this may match the rumors.
AMD’s Phoenix 2 processors (which don’t have much in common with the company’s Phoenix APUs) feature two “big” Zen 4 cores with 2MB L2 and 4MB L3 caches, and four “small” Zen 4cs with 4MB. Rumored to have a core. L2 and 4MB of L3 cache. This is a pretty amazing cache configuration. The APU is also said to feature an RDNA 3-based integrated GPU with 512 stream processors and a memory subsystem that supports DDR5/LPDDR5X. 3D center. @InstLatX64 AMD’s Phoenix 2 APU claims to have A70F8x CPUID, coelacanth dream Assert that the CPUID of the processor is 0x00a70f80.
For now, information about Phoenix 2 in general and 100-000000931-21_N [Family 25 Model 120 Stepping 0]Processors in particular need to be carefully considered, given the large number of products in AMD’s pipeline.
The Phoenix 2 processor, which allegedly has two Zen 4 cores and four Zen 4c cores, has been running the MilkyWay@Home client since early March, and someone inside or outside AMD has test-driven the chip. indicates that there is This could indicate that the CPU will be released in the near future, but the exact time is unknown. Meanwhile, according to unofficial information, AMD plans to release Phoenix 2 APUs in the second half of 2023.
