Headline is a little misleading. This is a comparison of power efficient mobile chips. The '3rd gen Ryzen' mobile chips are based on the last generation zen+ architecture. They're not the same '3rd Gen Ryzen' desktop chips based on the new zen 2 design that everyone is getting hype for right now.

edit: after digging in a little more, this link has some more interesting comparisons of supposed benchmarks from Ice Lake vs upcoming zen 2 based chips. https://wccftech.com/intel-10nm-ice-lake-sunny-cove-14nm-com...
