I'm very interested to see your AMD Ryzen 2 (3000) Benchmarks. Especially latency on memory.
Passmark can test just latecncy or just memory very quickly.

Im using AsRockB450 Pro4 / 3700x / Gskill c14 3000 16Gb
CPU on factory settings / RAM is set to 15 16 16 3600
I had a revalation seeing how bad AMD ddr4 latency was. So I got these settings dialed in and went from a 35 down to a 30.

I would also like to share, Ive contacted AS rock to fix the bios so I can set my voltage and frequency on the 3700x
properly. I can get 1.44 stable all core 4.2 but it wont fluctuate so I put it back to stock. Overclocking infinity fabric to 1900 got me nothing. fclk or bclk option got removed. I sent my results to engineering.

 
That's about same as I get with my system, Actually CPU score is identical (25582 at 4.4GHZ) and best Memory score 3102 but my RAM is Cl16 at 3600MHz. Same latency in P Test, 67 in Aida 64.
If your BIOS supports settings for FCLK (iNfinity Fabric Clock) set it to half the RAM frequency (1800 for 3600MHz RAM) as memory works best when it's 1:1with it and IMC.
