GamersNexus really hammering AMD's deceptive marketing around boost clocks. The only time it can hit its advertised boost clocks in when it's in the menu and you have near-zero load, and it barely touches it for an instant. Under even a single-core load it's failing to meet its advertised spec.
There was a lot of hubbub around this with the initial release, AMD released a BIOS which they claimed fixed this, looks like it still has not.

The performance is good enough as it is, no need to lie about it being 200 MHz higher than it can actually do. But here we are again 6 months later and AMD does it again...
