finally ordered Powercolor VII few days back. Will separate a rig and put this card alone. Plan is to mine ETH with it. One of my criteria was to have least noisy card. From RX 580, I have found powercolor red devil to be least noisy and low temperature. Anyone have any recommendation between powercolor/sapphire or AMD version of Radeon VII ?
They are all exactly the same, there is no custom card.
Distributors can rebuild or repackage their cards. Some do custom work by adding triple fans or using the standard set of double fans. So i disagee, the base GPU is the same model, but the distributor makes it unique/different.
From my experience, my Powercolor red devils (was running rx470s back then) were silent and never had any issues whatsoever.
What he is saying is that there is - currently - only one base model to choose from. There are only different brands selling the exact same reference design for now.
When AIBs have developped custom boards we'll see differences between them. But for now they're all the same card, regardless of which brand you go for.
