Poor Single core Performance with new 3800X

Lifetime Intel user but with my new build I decided to try Ryzen as the performance just can't be ignored.  I went with a 3800X as it was bundled the board I wanted for a good price.  Everything got set up, posted first time, Windows installed, all good.  

 

I then started to bench it, multi core is fine and right in line with what others are getting (CPU-Z, Cinebench). But single core seems lacking.  I'm getting 410-430 on Cinebench 20 single core and others seem to be getting 500+.

 

CPU: 3800X

Mobo: Asus TUF X570-Plus

RAM: G.Skill Trident Neo (F4-3600C16Q-64GTZNC) 3600MHz - CL16-19-19-39

GeForce 1660

 

Some things I have tried

- bios defaults

- bios performance profile 

- Ryzen Master, various profiles

- Different Windows profiles (Performance, Ryzen Balanced)

- AMD chipset from Asus and from AMD

- Flash latest Mobo BIOS

- All Windows Updates

- Too many BIOS overclocking profiles to count.  

 

I did manage to get the RAM running at 3600MHz, it wasn't by default.  

 

When I'm running single core bench, none of the cores seem to scale up anywhere close to 4.5GHz.  Even when I'm running multi-core bench, I'm getting about 4.3 max.  

 

I'm not a gamer, I do photo editing mostly and some video.  Single core performance is important as many photo apps or functions in the apps are just single threaded.

 

I'm hoping to figure out where the issue is because right now the single core performance is worse than the three year old 6700K it replaced.  Anyone have any ideas on what to try?
