Those two figures could also tell you the following;
1. Nvidia aren't selling a shed load of 1070/1080 cards which means a lot of people with a 980ti aren't upgrading.
2. There is definitely a time lag in the launches and this will take some time for AMD 480 to catch up. Considering it has sold so many in a smaller time frame is actually very positive.
3. The RX 480 and 1070/1080 are aimed at different segments so you're not comparing apples with apples.
I doubt that. 1080 is high end and TitanX is enthusiast. The price range is very different.4 As an enthusiast card the 1080 has already been replaced by the Pascal Titan X which could hurt sales.
5 The 1080 and more so the 1070 have been pushed down the performance stack and unless Nvidia start to reduce prices sales will start to stall.
6 Why upgrade now when Vega and Volta are just around the corner.
As always there are lies, damned lies and statistics. Believe what you want.
Of course those people are in the majority not upgrading. Nvidia isn't even expecting that if you listen carefully to them. 980Ti customers will wait for a Ti version or get a TitanX but definately not a GTX1080.
There is also a time lag between the GTX 1060 and RX480 but the GTX 1060 is already selling in higher numbers which makes AMDs situation worse as they are not alone in that segment. So there is no breathing room to cash in.
Of course they are. But if they way higher priced product is selling at the same rate or even better than there is a problem.
I doubt that. 1080 is high end and TitanX is enthusiast. The price range is very different.
Prices are not going down any time soon. If they are AMDs problems are increasing because than the mentioned cards will sell even more.
Neither Volta nor Vega is around the corner. Nvidia very likely has a very calm 6 months period in the performance, high end and enthusiast segment with the competition beeing completely absent. That is very comfortable. On the other hand AMD won't have this kind of luxury once they start to sell Vega. It is never a good situation when you are basically very late to the party. 2 months is ok, maybe also 3 but not half a year.
Titan X is not enthusiast, its Halo.
1080ti will be enthusiast, until then the 1080 is enthusiast, and the 1070/fiji is performance class..
AMD Gains 4.8% Market Share In Q1 2016
They did introduce the Rx 300 series, those were just rebadged Rx 200 but it stands to reason that some people wouldn't know about that and just bought them because they were "new".
