Performance clues for the desktop-grade Ryzen 7000 “Raphael” RDNA2 iGPU included in AMD's latest SMU driver update
Industry insider KOMACHI_ENSAKA recently tweeted some interesting findings regarding AMD’s upcoming Ryzen 7000 “Raphael” iGPUs. Team Red is constantly updating the System Management Unit (SMU) driver, and the latest version appears to contain references to the RDNA2 iGPU unit in the Ryzen 7000 processors. These iGPUs will be featured in both desktop and mobile models for the first time starting with the release of the 7000-series, unlike Intel’s processors that have been offering desktop and mobile iGPU versions for more than 10 years now.
Videocardz also hopped in to decipher KOMACHI_ENSAKA’s tweet, and it looks like some Ryzen 7000 iGPU configurations could include 2 Workgroup Processors (WGP), each with 2 compute units for a total of 4 CUs. The latest SMU update from AMD mentions that these CUs could end up clocked at 1.1 GHz. This would translate to 0.5 TFLOPS of single-precision compute performance, as calculated by Videocardz, or roughly a third of the Steam Deck’s performance that relies on 8 CUs clocked at up to 1.6 GHz.
As suggested by KOMACHI_ENSAKA and Videocardz, these figures would be sufficient for desktop users that have the option to add a discrete GPU for gaming and content creation. On the other hand, laptop users who cannot upgrade their systems with dGPUs might find this performance unsatisfactory, yet it is still unclear if AMD would offer more powerful iGPU options for the mobile and desktop processors. Traditionally, AMD has been offering up to 8 CU iGPU for the most recent mobile families, and we also know that the new Ryzen 6000 mobile processors come with 6 or 12 CU RDNA2 iGPUs, so a model with 4 CU could end up as a lower-end desktop solution.
