According to foreign tech media WccFtech, user @xinoassassin1 has shared a chart of the Phoenix ES APU clock frequency runs.

The chart does not provide details of the SKUs, but only shows a 6-core configuration with 2+4. There are 2 Zen 4 performance cores and 4 Zen 4c efficiency cores.

Core 0 and Core 5 are performance cores clocked between 4.0 – 5.0 GHz with an average of 4.2 – 4.3 GHz. The other 4 efficiency cores run in the 2.5 – 4.0 GHz range, with an average clock frequency of just under 3.0GHz.

It was previously reported that AMD’s “hybrid structure” processor corresponds to the Phoenix 2 mobile APU, adopts TSMC’s N4 process, has 2 performance cores and 4 efficiency cores, is equipped with 4CU RNDA3 core display, and consumes 15-28W. Products such as thin and light notebooks or game consoles. The flagship model of this series of processors is expected to be the R7 7740U, which is one bit lower than the full-core R7 7840U.

The chip is currently in the Coreboot patch database. AMD divides its Phoenix APU into two types, Phoenix (1) and Phoenix (2), which means that this APU will serve as the second revision of the Ryzen 7040 series, which we will refer to as Phoenix 2 hereafter.

According to Coelacanth-Dream, there are two GFX1103 “RDNA 3” IDs for the AMD Phoenix APU, one of which is GFX1103_R1, which has a full 512 KB L2 cache, while the second, GFX1103_R2, has only 256 KB.

Simply put, AMD felt that the low-power mobile platform might not be able to use the 512 KB L2 cache, so it was castrated to half of the original in the new revision, and it is expected that some manufacturers will use it for entry-level platforms to replace Mendocino APU.

In fact, the whistleblower @MLID has also mentioned a “Little Phoenix” product with similar specifications before, but this is an “ultra-low power and compact” chip for the Steam Deck handheld. It is not ruled out that this is the same possible series of products.

According to @Kepler_L2, who has been following the Phoenix 2 APU, this series of chips will also have a lower number of computing units, which sounds like a conservative version of the Phoenix APU, and the efficiency data of this Phoenix 2 APU will definitely be interesting.

The first laptops powered by AMD Phoenix APUs will be unveiled in March 2023, and we think we might see this Phoenix 2 product later in 2023, like a handheld.
