AMD Ryzen 7000G APU Series Includes Lower End Models Based on "Phoenix 2"
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.Both "Phoenix" and "Phoenix 2" dies feature an identical I/O that includes a dual-channel DDR5 memory interface (4x 40-bit sub-channels), and a 24-lane PCI-Express Gen 4 root complex (4 fewer PCIe lanes than the "Raphael" MCM). On desktop motherboards, this could mean that the x16 PEG slot will run at Gen 4 speed even on B650E and X670E motherboards, and only one of the two CPU-attached x4 NVMe slots will be active, as the remaining 4 lanes from the processor will be allocated as chipset bus.
The leak also includes a handful of entry-mainstream mobile processor models based on "Hawk Point," which is likely a refreshed "Phoenix" and "Phoenix 2" silicon that carries forward "Zen 4" CPU cores to the Ryzen 8000 series, much in the same way that the "Zen 3" based "Rembrandt-R" was slotted into the Ryzen 7030 series. Among the processor models listed here are the Ryzen 7 8840U (100-000001325-00), Ryzen 5 8540U (100-000001326-00), Ryzen 5 PRO 8540U (100-000001331-00), Ryzen 3 8440U (100-00000XXX-00).Image courtesy: HXL (Twitter)
