That's the single core improvement you have between Zen 2 and Zen 3, but Zen 3 also has sightly better power usage than Zen 2 and Zen 2 was already superior (allegedly - I haven't actually used a Zen 2 mobile device since nothing really premium was built with it) - Zen 3 mobile isn't out yet but I suspect it's going to be a much better experience for mobile just like Zen 2 was compared to 10th gen intel.
