High-performance chiplet Ryzen processors are finally going to have iGPUs. The specs are starting to emerge
One of the drawbacks of the higher-tier Ryzen processors (3000X, 5000X models) is that they do not have an integrated GPU. However, this should change with the new 5nm Ryzen 7000 generation with Zen 4 architecture. AMD hasn’t announced it yet, but according to numerous leaks, this generation will also already provide integrated graphics. Now another proof has emerged and also some indication of its specs.
Patches for Linux drivers have revealed specifications for a GPU that could be the integrated graphics of the Ryzen 7000 chiplet processors (codenamed Raphael). A line regarding the SMU controller (which controls the clock speeds and other aspects of Ryzen processors when they are running ) states that the GPU clock speed should apparently be 1100 MHz. Presumably this is the maximum boost clock, not the gaming or base clock.
This code does not state the second important specification, namely the number of units. According to estimates and tips of leaker Komachi Ensaka, maybe 256 shaders (4 CU/2 Workgroup Processors) could be used, probably of RDNA 2 architecture. It is believed that the iGPU is probably integrated in the IO chiplet of Ryzen 7000 processors. That die is made on 12nm process node in today’s generations, but the 7000 generation could use newer technology (6nm node is being speculated, which would have the advantage that some blocks from the Ryzen 6000 “Rembrandt” APUs could be reused).
The low frequency and small number of units would mean that the gaming performance would not be very high. However, VideoCardz estimates that it could be as much as a third of the graphics performance of the Steam Deck console. However, 256 shaders is also a configuration of even common, not-quite-as-powerful integrated graphics cores in Intel Rocket Lake or desktop Alder Lake processors (such as the Core i5-12500).

But this integrated graphics is mainly aimed at eliminating the need for a dedicated GPU for common desktop and office use, it does not particularly need any sort of higher 3D performance. Video output support will be the important thing, and probably also acceleration for video playback and encoding.
Release possibly in summer, a laptop version might be in the cards
These Ryzen 7000 processors were previously expected to come out sometime at the end of the year, but more recently there have been reports that the timelines have changed and their release could be months earlier. Supposedly, they could come in the summer, there have been (speculative?) conversations about August. Naturally, the new AM5 platform motherboards using DDR5 memory should come out as well for these processors.

What’s more, it is possible that a laptop version of these processors could probably be released as well. The Ryzen 3000 (codenamed Matisse) and 5000 (Vermeer) generations of chiplet processors could not be used in laptops due to the lack of an integrated GPU, so AMD only offered monolithic octa-core “APUs” in the mobile area.
But Raphael/Ryzen 7000 could already have a mobile, perhaps 45W version (Raphael-H) thanks to the presence of integrated graphics. Such processors could have up to 16 Zen 4 cores, but it is not yet clear how well the chiplet design will work in laptops, whether, for example, battery life will be reduced due to higher power consumption.
