As you can see in the validation Voltage is at around 1.344V but that is with Vdrop, in UEFI its 1.398V and thats default, the Turbo Boost voltage is 1.45V but with Vdrop it stays at about 1.42V, CPU-Z cannot report the Boost voltage for Ryzen, only default voltage.
Raven Ridge has very high Vcore from the get go, some users report even 1.5V when CPU is boosting.
Summit Ridge has lower default voltage even when boosting but it cannot sustain the boost on more than 1-2 cores.
In this validation you can see the CPU boosted all cores to 3.75GHz, and went to 3.8GHz for the single core benchmark.
Default clock for 2400G is 3600MHz

The link doesn't seem to work. In any case those voltages seem quite high, since 1.35V is supposed to be the safe limit for 24/7 (or 1.4V according to some sources), which means under load you're already near the "limit" (it's not a hard one, of course). But then that voltage also depends on which sensor it's taken from, and the limits may not be exactly the same for Raven Ridge and Summit Ridge.
Ryzen 5 1500X, ASRock AB350M Pro4, 2x8 GB G.Skill Trident Z 3466CL16, EVGA GTX 1060 SC 6GB GDDR5, Corsair RM550x, Samsung 960 EVO SSD (NVMe) 250GB, Samsung 850 EVO SSD 500 GB, Windows 10 64-bit

The APUs don't use the infinity fabric to link 2 core clusters like other Ryzen CPUs do. This alone will result in better per core performance. Interesting results for sure. I know the R3 and R5 1k series both disable 2 cores from each CCX rather than utilize a single 4 core CCX.

I wonder if the APUs even have the infinity fabric at all?
