5 nm Zen4! AMD Revolutionary Phoenix APU Exposure

AMD's APU concept has always been aimed at replacing low-end entry-level stand-alone graphics cards, and it has done so to some extent. However, it has always failed to do so, as stand-alone graphics continues to grow rapidly.

AMD released Ryzen 6000H and Ryzen 6000U series at the beginning of the year, integrating the GPU of RDNA2 architecture for the first time. With a maximum of 12 computing units and 768 stream processors and a maximum frequency of 2.4GHz, it can be described as a leap forward.

AMD is also preparing a revolutionary APU, codenamed Phoenix, which, as its name suggests, will revolutionise the market for desktops and laptops.

The exact specifications of the Phoenix APU are not known, and sources vary, but the Phoenix APU will use a 5nm Zen4 CPU architecture.

The probability of GPU is RDNA2 architecture. However, for 5nm process redesign, there is a certain probability of the next generation RDNA3, that is native matching 5nm.

Again, the number of cells increased dramatically, with some saying 16 or more and others saying 16-24. That's 1024-1536 stream processors, up over RX 6500 XT and close to RX 6600.

In terms of sheer power, the Ryzen 680M in the Rayon 6000H/U Series has surpassed the RX 6400 and is very close to the Xbox Series S. Assuming the frequency is around 2.2ghz and the number of cells is increased to 24, it is completely possible to exceed RX 6500 XT!

The memory may support LPDDR5X or both DDR5 and LPDDR5. There may be a new Cache system, not Infinity Cache, but more like a unified CPU, GPU level 3 Cache. There may also be unified memory addressing space, similar to PS5.

It is not clear when Phoenix APU will be released. But that will certainly come some time after the 5nm Zen4-built Ryzen 7000 series (early spring next year at the soonest). The latter will also be fully integrated with RDNA Gpus, but will definitely focus more on CPU performance.
