Also, regarding your first statement, the different clocks by different vendors and it not being supported by the previous firmware rev kicking it into a safe mode isn't the case.

Those numbers (eg 750 MHz) sound like what our FW engineers were talking about for both Linux and Windows (and others)... maybe there's a 2x multiplier in the reporting for Windows, will check. My recollection was that reference gave 750 MHz reported while the new VBIOS gave something like 875.
If you go outside the firmware's limits the clock defaults to 300 MHz. That matches the performance Michael was seeing.
Okay that 300MHz thing is super interesting. I've been trying to test out this navi overclocking utility called powerupp that leverages upp and if I tried to set it to ANYTHING above the stock 1780MHz for this card, all clock states would get forced to 300MHz. I have the new firmware and new vBIOS, but what I don't understand is why it would do that if I don't got above the firmware limit of 1820MHz. Cause the stock frequency is 1780, but pp_od_clk_voltage and pp_table shows the available clock RANGE to go up to 1820, so I should theoretically be able to set the clocks to anything up to 1820 before it defaults to 300MHz. But instead, it's defaulting to 300 if I set it to 1781 even. Which further doesn't make sense because I CAN set it to anything up to 1820 with radeon-profile and it doesn't go to 300, it goes to the correct frequency. Here is a link to the github issue page if you need more info https://github.com/azeam/powerupp/issues/1
