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)

I Would buy an ultra efficient monolith designed APU with capable 3D performance for online competetive games on low settings with 144fps performance.
But they kill their APUs with their own market policy. A Cheap CPU + any cheap dGPU with a similar budget limit can provide also high efficiency but much more 3D performance.
(For example a GTX 1650 + i3-12100F/R5-3600 is just a "little more" money than a 5600G. CPU+dGPU is +50% more money than an 5600G itslef, but CPU&dGPU combo gives +100% - 200% 3D performance, while an 12100F and a GTX 1650 is still have a very good Performance/watt efficiency.)
I would expect a real AMD Fusion: Like They should design an AMD APU with more CU with Quad Channel DDR5 controller + MOBO brands should produce APU specific motherboards with 4 channel DDR5 with max. ~90-120W VRM capacity with high efficiency and only 1-2 PCIe x4-x8 slot need for upgrade (like Sound card for players/HTPC or drive controller+10G LAN for NAS, etc...). No need PCIe 4.0/5.0 x16 for dGPU in this case.
Only very expensive manufacturers make something similar (like minisforum), but their disadvantage is the price.
From all accounts I have heard GDDR6 as system memory is a really bad idea due to the huge latency penalty.
They are taking their darned sweet time making these APUs. APU laptop cores have been out for 12 months, and I don't think it tales 12 months to convert the SoDIMM I/O pins to DDR5 ... these CPUs are so late I doubt they will see much of a market, most people who wanted a powerful desktop iGPU have already bought something with a 780M iGPU from Minisforum.
