Im not sure about their numbers, but your analysis is surely wrong.
Adding up shipments and sales can't result in decrease in units. At least until they are not selling negative hardware, like a negative 0.5GB of VRAM
Perhaps I my point wasnt clear. I kind of hate posting on a phone at work, always a sloppy result..
The article is supposed to represent the current user market share. They add up sales over the past several years and count them as individual gamers. They are assuming that these machines are all still being used for gaming and that each one is a separate person.
Counting years old machines that are all assumed to be active gamers and in the tally. See not only do years old gaming laptops break, many gamers buy new hardware to replace their aging hardware. That its strange to assume that all those machines are still being used and counted in their total gamer market share data. I
This report is suggesting these machines represent individuals. I think it's very very fuzzy.
Other issues,
The consoles just now become x86 machines, yet the data they give goes back well before x86 consoles. Its impossible yet there it is, right there in the chart. Did JPR not realize that the last gen consoles were not x86? Or did someone one on their team who put this together not know? Its entire bases is supposed to be x86 gamer share but they have large numbers and data from non x86- last gen consoles.
Also, even if you disregard the flaw of charting millions of non x86 machines in their x86 gamer market article - the numbers do not even add up. The amount on non x86 consoles shown on their chart as x86 machines is higher than the xbox 360 sales. Did they add in nvidia gpu ps3 sales and count them for amd?
The last problem.
Amd notebooks are being counted as a gamer in a very high percentage. Many of them are not viable gaming machines at all. They just don't have they capability. That's not a knock on them, just saying. Many people who bought less power apus didn't buy it as their primary gaming device.
They throw out tablets, even x86 tablets. I know far more people who have tablets that are used to play games than people who use low power notebooks. I would say that nearly all tablets in homes are used to play games. I mean, that is pretty much what tablets are used for in homes. Entertainment, fun, and games. These tablets are gaming devices.
But yeah, throw out tablets and show non x86 consoles. X86 mobile, thrown out.
Gamers have many outlets. And I do think amd is serving a good chunk of these gamer outlets. But these figures are totally manipulate. And for what reason?
Gamers have many devices. They go through many devices. Many frequently update as well. Most ps4 owners were previous console owners as well. Many still have their old console. They may have a netbook and a desktop pc.
But if we decide to take the individual out and say strictly from a device standpoint. The data is so skewed here, its completely bizarre. There are so many huge problems in this, its unbelievable.
My opinion is now leaning towards intentional, its hard to see how its accidental. I have moved on from how to why.
