One interesting thing here is that AMD is competing with a former unit of itself. As you may know, AMD sold its mobile chip unit to Qualcomm in 2009. This technology is still known as Adreno, which is an anagram for Radeon. Earlier leaks suggest the Ryzen C7's graphics beat Qualcomm's Adreno 650 by 45 percent:
The SoC looks like a beast. Manufactured on TSMC 5 nm process, it features two Gaugin Pro cores based on recently announced Arm Cortex-X1, two Gaugin cores based on Arm Cortex-A78, and four cores based on Arm Cortex-A55. This configuration represents a standard big.LITTLE CPU typical for smartphones. Two of the Cortex-X1 cores run at 3 GHz, two of Cortex-A78 run at 2.6 GHz, while four little cores are clocked at 2 GHz frequency. The GPU inside this piece of silicon is what is amazing. It features four cores of custom RDNA 2 based designs that are clocked at 700 MHz. These are reported to beat the Adreno 650 by 45% in performance measurements.

Looks reasonably legit and certainly a very desirable flagship SoC. They did misspell the name of Paul Gauguin, scholar of Cézanne and friend of Vincent van Gogh though. pic.twitter.com/n9NSUirqpL
