That would be weird because the the 470 has 32CUs compared to 36 for the 480. If they are clocked the same then there would only be about 8-10% real-world performance difference.
I rather suspect that that is a score form a 480.

I thought the mobile variant of 480 was Polaris 11 not Polaris 10
and if that's mobile score......
GP106 could be up to 220mm^2. there is no official size information but form the public photos of dies people have estimated 190-220mm^2

If true that should set alarm bells ringing for the more sense than money crowd. Things are only gonna get worse with prices. The Nvidia money counters are laughing all the way to the bank,
Meanwhile at Nvidia HQ "How did it go Bob?" "Well, not only did they swallow the price increase but there selling better than ever".

No Polaris 11 are the boring super slow parts
GM206 is 227mm^2 and GP106 appears to be a bit smaller. Numbers have guessed from 170-200mm^2.

But think about it more easily than that, GM204 400mm^2, GM200 600mm^2, GM206 227mm^2. You need good product separation in terms of size, 314mm^2 is honestly just way to close to 220mm^2, 180-190mm^2 makes a hell of a lot more sense if you're spreading your chips around the price/performance brackets. The only unknown would be GP108, there is only so small you can get while having any worthwhile performance because a higher percentage of the core is taken up by non gaming things the smaller a core gets. I can't see GP108 being smaller than 100mm^2 regardless of GP106 size because video block, display output blocks, all need to be there and are basically the same size in GP108 as they will be in GP102.
Anyway as you say estimates I've seen put it around the 190mm^2 mark and that makes the most sense when considering the the die size of the next chip up. You've got to think about memory as well, it doesn't make much sense to have a 256bit bus on GP106 so the rumour of 192bit makes sense, gddr5x doesn't make sense for GP106 though, so how much bandwidth can it have 60% of what Gp104 gets with gddr5x... now anyone want to guess what 60% of 314mm^2 is, 189mm^2. I would say, yeah, 190mm^2 makes a heck of a lot of sense for GP106.

I think it is just a sign of a changing landscape in PCs. The low end models are pretty much gone because IGP and APUs are good enough, people are just moving up a tier. and nvidia have created new tiers for the enthusiasts to move in to. As fun as a race to the bottom is for numerous in the short, the long term health of the industry requires sufficient profitability. The extremely successful sales of the 1080 is a good indication that Nvidia read the market correctly and there is a substantial user base willing to upgrade to the fastest card money can buy.
as long as Nvidia and AMD both keep selling amazing cards like the 970,1070 and 480 then there is little to worry about.
I think he also mentioned something like 5000 units? Lol
That does not mean much in the short term. Thinking logically it is easy to see that this is only the initial rush from people who like to have the best. Once that has been fulfilled, demand will die down as there is a smaller number of people who splash £600+ on a gpu.
If the rumours of the RX 480 performance is true, then it will sell in much higher quantity and faster IMO.

You have not much stock, silly prices and only a few available as a retailer do you say
A/these are selling really poorly, you don't need to rush to buy one of those 10 in stock we have left because they aren't going in the next 10 minutes or
B/ zomg, these are like the best selling card ever, everyone absolutely totally loves them, better buy it because there is 10 left and they might be gone by the time you make your mind up and look at all of those out of stock, never know when they'll come back in...
B is a time honoured tactic of salesmen, A is not.

Just doing some size comparissons using that image, GP106 is as low as 67% the area of GM206. it is more than likely under 200mm^2.
which using Nvidias numbering convention, would be smaller than gp106.

I know about that initial size guesstimate but sometime later I found a more detail comparison with some actual measurements and math which suggested something at least 200mm^@ and bigger than most mainstream die sizes. The GM206 die is not so useful because it was a 2dn generation 28nm core so increased in size to facilitate performance.
Can we stick to GPU names? the whole thing becomes cryptic when you something as obscure as die codes.
I'm assuming the <200mm core is the GTX 1060?
I think with it being just over half the size of the 1080/70 die its probably not going to match the 480, i very much doubt Nvidia wanted to sell that for less than half the 1070, IE under £200.
RX 470: 16,164

My 970 with factory overclock (1354Mhz): 15,991

But bigger than GP108. IF GP 108 is something like 100-110mm^2, which sis around the smallest that makes sense and you have 314mm^2 GP104, then you have to fit in 2 distinct cores within these sizes.
that is about size comparison, its a die of a known size, so when doing a comparison like that its a good guide.

I know, but than you actually get measuring the numbers are at least 200mm^2 AFAIK.
OcUK forums need a browser addon like reddit so you can tag people, for instance "believes wccf spew" next to someone's name would help you remember not to bother arguing with that person.
Starting to think Volta is the last hope for a truly epic/worthy G80 successor.
It'll be faster than Volta next week
