I think my calculations are correct here

  Model       Zen+  2060
  Cores       4     1920
  Threads     8     1920
  Cycles      2.3   1.365
  FP64 GFLOPS 2944  163
  FP32 GFLOPS 5888  5242
  FP16 GFLOPS 11776 10483

So it would kind of make sense yeah. 2060 isn't that strong.

But note: I'm not totally sure on the Zen+ theoretical speeds
