Nope, the only "change" is on the Ryzen 7 5705G SKU where the "boost" frequency of the Radeon "Vega 8CUs" iGPU goes from 2000MHz to 2200MHz, which will provide a performance gain ranging from 2 to 4% depending on the games (and again this will also depend on the memory bandwidth of the VRAM allocated via the DDR4 RAM and therefore directly on the operating frequency of the latter). And there does not seem to be any security or other update internally at the silicon level because it is always the same "CZN-A0" stepping for their productions, so clearly no other new features, it is clearly and almost only rebadging in order to get rid of the last stocks of "Cézanne" wafers/dies.Looks like amd is bringing new APUs (5605 and 5705G) for am4 maybe Asrock fixes the setting not saved problem when adding Support to the cpus. And maybe (even though I doubt it) AMD adds PCIe 4 support to them.
Frankly not very nice AMD frankly you could have inflated the base and boost frequencies a little, like 4.0 GHz base (+200MHz) and 4.8 GHz for the boost (+200MHz) for the "flagship", the Ryzen 7 5705G, and between +100 and +200 MHz for the other lower models, it would always have been more valid and especially more seller, and I am sure that these slight increases in frequencies would not have caused any instability problems, without worries moreover the +200MHz on the boost frequency of the iGPU could also have been carried over to the lower models with "cut" iGPUs, this would have brought the Radeon iGPUs "Vega 7CUs" and "Vega 6CUs" respectively to 2100MHz and 1900MHz, that would have always been something gained...
