AMD Polaris architecture – GCN 4.0

cheaper without a doubt, same perfs not likely, polaris should be slower by 10% best case scenario, 30% slower worst case scenario

Except the 1070 is smaller than Polaris 10.

So knowing pretty much nothing other than that, I don't see why the assumption is its slower.

errr where did you get that info? 1070 has the same die size as 1080 which is overall a bigger chip than what has been spotted to be polaris.

He's assuming a cut down 1080 die is effectively 75% of the full size putting it around same size. This completely ignores the benefits of having dead silicon and the effect on yields so its a bit of a wonky assumption.

Yes, I'm sure if you took a 300mm2 chip and disabled half of it, it would perform much better than a fully enabled 150mm2 chip...

it could probably do with locking until there is actually some news.

I would not go that far.

I think it has been made clear nvidia talk is not wanted here. Hopefully it will stop. If people want to do that, they should create a new thread named amd vs nvidia or something.

Polaris will be popular for streamers.

That's if the dedicated hardware encoding works really well. Intel QuickSync has been very popular and effective; but Streaming does eat up CPU cycles. Hopefully it works well; I'm interested in Polaris for that hardware as well.

Mostly for video encoding after editing :D

Just using it an an example with easy maths.

The real-world example would be suggesting a 315mm2 chip with 25% disabled would perform much better than a 236mm2 chip that was fully enabled.

Also Polaris 10 is equivalent of 266-300mm2 on 16nm, depending on whether they go for full density or not.
