AMD's "Phoenix" monolithic processor silicon drives the company's Ryzen 7040 series mobile processor lineup, and possible some of its upcoming Ryzen 7000G desktop processor models. It is the first chip from the AMD camp to feature an AI accelerator, besides up to 8 "Zen 4" CPU cores, and a large iGPU based on the latest RDNA3 graphics architecture, with up to 12 compute units, the latest display I/O and media acceleration capabilities. Over the course of its lifecycle, AMD realized that it can't use the nearly 200 mm² silicon built on the expensive 4 nm node to power lower-end processor SKUs, and so developed the smaller 137 mm² "Phoenix 2" silicon that lacks the AI accelerator, has a smaller iGPU with just 4 compute units, and a unique hybrid CPU with 2 "Zen 4" and 4 "Zen 4c" cores. We're now hearing that the company is designing even more derivatives.

The PCI ID Repository discovered two new IDs believed to reference the iGPU models of "Phoenix 3" and "Phoenix 4" chips. At this point we have no clue what the two chips could be, and what the mixture of their CPU, iGPU, and AI accelerator components could be, especially given that AMD is able to carve out Ryzen 3 SKUs from "Phoenix 2." We speculate that "Phoenix 3" and "Phoenix 4" could reference rebranding such as "Escher," although it could even be entirely new chips with different combinations of "Zen 4" and "Zen 4c" cores.

ASRock began rolling out UEFI firmware updates for its Socket AM5 motherboards that encapsulate AMD AGESA 1.1.0.0 ComboAM5PI microcode. This would be the second release of AGESA to support AMD's upcoming Ryzen 7000G "Phoenix" and "Phoenix 2" desktop APUs that the company reportedly plans to launch later this year. The AGESA 1.1.0.0 microcode comes with the SMU version 76.72.0 for "Phoenix" and "Phoenix 2," and continues with version 84.79.223 for "Raphael" and "Raphael-X" processors.

Unlike several past generations of Ryzen branded desktop APUs that only had 2-3 processor models in the retail channel, AMD is reportedly planning a slightly bigger lineup of APUs for the Socket AM5 platform, consisting of Ryzen 3, Ryzen 5, and possibly Ryzen 7 processor models, and their Ryzen PRO variants. The Ryzen 3 and Ryzen 5 models are expected to be based on the "Phoenix 2" silicon that has a combination of two "Zen 4" and four "Zen 4c" CPU cores and an iGPU with 4 compute units; while it is rumored that at least one Ryzen 5 and Ryzen 7 processor model will be built on "Phoenix," which has up to eight "Zen 4" cores, and a large iGPU with up to 12 compute units. So far we haven't seen reports of AMD bringing Ryzen AI to the desktop platform.

AMD is giving final touches to its Ryzen 7000G series desktop APUs that bring the 4 nm "Phoenix" monolithic processor silicon to the Socket AM5 desktop package. The star attraction with these processors is their large iGPU based on the latest RDNA3 graphics architecture, featuring up to 12 compute units worth 768 stream processors, and full DirectX 12 Ultimate feature-set support. These processors should be able to provide 720p to 1080p gaming with entry-medium settings, where you take take advantage of FSR for even better performance. At this point we don't know whether the Ryzen AI feature-set will make its way to the desktop platform. "Phoenix" features an 8-core/16-thread CPU based on the latest "Zen 4" microarchitecture.

An interesting development here is that not only is AMD bring the "Phoenix" silicon to the desktop platform, but the processor models highlighted in this leak reference the smaller "Phoenix 2" silicon. This chip is physically smaller, features a CPU with two "Zen 4" and four "Zen 4c" cores; and an iGPU that has no more than 4 compute units worth 256 stream processors. The OPN codes of at least three processor models surfaced on the web. These include the Ryzen 5 PRO 7500G (100-000001183-00), the Ryzen 5 7500G (100-00000931-00), and the Ryzen 3 7300G (100-000001187-00). No specs about these chips are known at this point. The PRO 7500G and regular 7500G are expected to feature the full 2+4 core configuration, while the 7300G could probably feature a 2+2 core configuration. If the company does plan a 7600G and 7700G, those would likely be based on "Phoenix" with 6 or 8 regular "Zen 4" cores.

AMD is preparing to launch its first APUs on the Socket AM5 desktop platform, with the Ryzen 7000G series. While the company has standardized integrated graphics with the Ryzen 7000 series, it does not consider the regular Ryzen 7000 series "Raphael" processors as APUs. AMD considers APUs to be processors with overpowered iGPUs that are fit for entry-mainstream PC gaming. As was expected for a while now, for the Ryzen 7000G series, AMD is tapping into its 4 nm "Phoenix" monolithic silicon, the same chip that powers the Ryzen 7040 series mobile processors. Proof of "Phoenix" making its way to desktop surfaced with CPU support lists for the latest AGESA SMUs (system management units) compiled by Reous, with the AGESA ComboAM5PI 1.0.8.0 listing support for "Raphael," as well as "Phoenix." Another piece of evidence was an ASUS B650 motherboard support page that listed a UEFI firmware update encapsulating 1.0.8.0, which references an "upcoming CPU."

Unlike "Raphael" and "Dragon Range," "Phoenix" is a monolithic processor die built on the TSMC 4 nm foundry node. Its CPU is based on the latest "Zen 4" microarchitecture, and features an 8-core/16-thread configuration, with 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The star attraction here is the iGPU, which is based on the RDNA3 graphics architecture, meets the DirectX 12 Ultimate feature requirements, and is powered by 12 compute units worth 768 stream processors. Unlike "Raphael," the "Phoenix" silicon is known to feature an older PCI-Express Gen 4 root complex, with 24 lanes, so you get a PCI-Express 4.0 x16 PEG slot, one CPU-attached M.2 NVMe slot limited to Gen 4 x4, and a 4-lane chipset bus. "Phoenix" features a dual-channel (4 sub-channel) DDR5 memory controller, with native support for DDR5-5600. A big unknown with the Ryzen 7000G desktop APUs is whether they retain the Ryzen AI feature-set from the Ryzen 7040 series mobile processors.
