Use Zen 4 and Zen 4c mixed design, AMD Phoenix 2 CPU more information exposure

Thanks to CTOnews.com netizens Daniel Wu in South China, AMD tragic future, Xiao Zhanche's clue delivery! CTOnews.com, March 21 (Xinhua)-- AMD announced the APU codenamed "Phoenix" at CES 2023, and the notebook with this APU is expected to go on sale in the near future. The Phoenix is packaged in 4nm process, and up to 8 Zen 4 cores, 12 RDNA3 computing units and multiple dedicated AI processors can be selected.

CTOnews.com reported as early as November last year that AMD will launch a "Phoenix 2" branch, a design branch developed specifically for low-power application scenarios. It has fewer cores and smaller GPU, but the biggest change compared to the original version is the use of hybrid architecture.

But unlike Intel's large and small cores, which integrate two different processor architectures, AMD uses the Zen 4 architecture. The message says that the "Phoenix 2" branch uses the same instruction set, but differs in terms of performance and clock frequency.

The message says that "Phoenix 2" uses two full-fat Zen4 cores and four low-power Zen4c cores for background tasks. RDNA 3 GPU has been reduced from six WGP (12 CU) to only two (4 CU), and TDP has dropped from "35W +" to a maximum of 28W.
