AMD Radeon VII benchmarks(?)

[Dino]

Hello,

I'm not understanding something on the benchmarks. It seems AMD kills Nvidia on 7-zip? Can the difference be this much? (snippets from two different tests people have posted)

System specifications:

* Intel Xeon E5-2680v2
* 128 GB RAM
* 4 XFX Radeon VII
* hashcat v5.1.0-1474-gd315f614 (git)
* rocm-dkms 2.10.14
* Ubuntu 18.04

Stock clocks, stock fan, sclk/mclk variable.

These are wildly different (H/s vice kH/s)?

Go easy on me. I'm new at this.
