It's all in the stepping. Stepping C is a third rework of the chip after A (engineering samples) and B (first run tests iirc), then 7 is the 7th revision of that stepping.

TBH all this says is that the chip could've been released probably a couple months ago, but AMD wanted to work on it more/build more stock.

Guys, this thread will become Polaris Owners Thread anyway so just remove the question mark from title tongue.gif

If you look at some other AMD/ATI cards, they launched at A0/A1 revision. Base metal layers usually do not see a respin unless something was TERRIBLY wrong.

Seeing as this is a whole new node and new transistor type, AND AMD had near exclusive access to the fab... I guess its not surprising it has seen so many revisions.

Id imagine "hot lots" turn around really quickly when you are the only one using a production line, or you could send three spins down the line at the same time and pick the best performing one.

Pure speculation here... but different spins can have radically different power/clock curves. Perhaps there is a specific variant for mobile?

Can you trying over clocking it? Some leaks have said they can't even get 5% overclock on the RX480, but we don't know if that's due to power, temperature, or stability. For instance my Strix Fury basically will not overclock at all. Anything over 3-5% and it's unstable in games. Doesn't matter how much voltage I pump into it, or how high I set the fan speed.


I'm interested to see what the polaris chip itself can do. Crank up the fan speed to keep it cool and see exactly how far it can do(even with a noisy stock cooler). That way we can see what the AIB cards will be capable of.


Thanks man thumb.gif

That is ok performance for the price. OC ability is key to my level of interest.........Would you kindly?

Wonder if AMD planned for this, or if they got delayed by a good year lol

I don't see an A0/A1 revision ID here, there are a couple with Device IDs like that though.

There's the C4, which was reported first, then C9, C0 and others iirc.

In general, A0 or A1 is risk production like GP104.

Can you explain what risk production is actually?
I can't find a good place to read about respins, revisions and concepts like risk production.
