The CPU and GPU clocks appear to be quite low compared to mobility models like the Ryzen 7 4700U, but the "Artic" chip proves to be faster, at least in CPU-related tests, and the DDR4-3200 support certainly helped. On the iGPU side, however, the performance is not that great, as it turned out to be slower than a Vega 6 model.
