An unannounced AMD cpu recognized as Family members 25 Version 120 Tipping 0 lately turned up in the MilkyWay@Home data source. The CPU can refine 12 strings all at once and also the CPU professional @InstLatX64 thinks that this is AMD’s codenamed Phoenix az 2 cpu, loading 2 high-performance Zen 4 cores and also 4 energy-efficient Zen 4c cores.
AMD Eng Example cpu noted 100-000000931-21_N [Family 25 Model 120 Stepping 0] includes 12 rational cores (i.e., 6 physical cores with synchronised multithreading) and also reports concerning 1MB of cache, which shows that the MilkyWay@Home customer can not properly figure out the quantity of cache included by the chip. The listing itself does not confirm that we are handling AMD’s crossbreed Phoenix az 2 cpu with Big.Little-like core setup, however 6 physical/12 rational cores included by an unidentified CPU provides us a tip that this might match the reports.
AMD’s Phoenix az 2 cpu (which does not have a great deal alike with the business’s Phoenix Az APU) is reported to include 2 ‘large’ Zen 4 cores with 2MB L2 and also 4MB L3 cache in addition to 4 ‘little’ Zen 4c cores geared up with 4MB L2 and also 4MB L3 cache, which is an instead shocking cache setup. The APU is likewise claimed to load an RDNA 3-based incorporated GPU with 512 stream cpus and also has a DDR5/LPDDR5X-supporting memory subsystem, according to 3DCenter @InstLatX64 declares that AMD’s Phoenix az 2 APU has an A70F8x CPUID, whereas CoelacanthDream insists that the CPUID of the cpu is 0x00a70f80.
In the meantime, any kind of info concerning Phoenix az 2 generally and also the 100-000000931-21_N [Family 25 Model 120 Stepping 0] cpu specifically must be taken with a grain of salt because AMD has tons of items in the pipe.
The claimed Phoenix az 2 cpu with 2 Zen 4 cores and also 4 Zen 4c cores has actually been running MilkyWay@Home customer because very early March, which shows that somebody within AMD or perhaps beyond the business is examination driving the chip. This might be an indication that the CPU will certainly be launched in the direct future, though it is uncertain when precisely. On the other hand, based upon informal info, AMD is readied to launch its Phoenix az 2 APUs in the 2nd fifty percent of 2023.
