The AMD Radeon VII Review: An Unexpected Shot At The High-End
by Nate Oh on February 7, 2019 9:00 AM ESTPower, Temperature, and Noise
As always, we'll take a look at power, temperature, and noise of the Radeon VII. While it is customary to look at voltages and clockspeeds, given the SMU changes that was not possible this first time around.
The noise levels of the card look surprising at first blush. Ultimately, what's happening here is the consequence of a very aggressive fan curve, one that invests all potential acoustic improvements of an open-air triple fan card for cooling capability. Going this route makes the fan noise comparable to RX Vega 64's blower.

So FP64 is 1:4 and not 1:8 or 1:2 as previously known?tipoo - Thursday, February 7, 2019 - link
Yep, looks like they changed the cap in vBIOS based on feedback.Which also means they could have uncapped it, but it's still cool that they did that.

Does that mean it could be potentially unlocked by some bios mod?tipoo - Friday, February 8, 2019 - link
I hope so!Hul8 - Thursday, February 7, 2019 - link
I don't think it was ever reported or assumed to be 1/2 - that best possible ratio is only for the pro MI50 part. Early reports said 1/16.Ryan Smith - Thursday, February 7, 2019 - link
For what it's worth, when we first asked AMD about it back at CES, FP64 performance wasn't among the features they were even throttling/holding back on. So for a time, 1/2 was on the table.GreenReaper - Thursday, February 7, 2019 - link
So it was *your* fault! ;-pBigMamaInHouse - Thursday, February 7, 2019 - link
Asrock just posted vBios: is this with the FP 1:4 or newer?https://www.asrock.com/Graphics-Card/AMD/Phantom%2...

We're not currently aware of any Radeon VII cards shipping with anything other than 1/4 rate FP64.BigMamaInHouse - Friday, February 8, 2019 - link
So maybe it's new bios with some fixes?Did you tried it since all cards are the same reference design?
