Late last year, if I remember correctly, AMD talked about two design wins, one for an x86 part and another for an ARM one, stating something along the lines of "with one of them going beyond gaming". Yet half a year later we still don't know what they were talking about.

Then, around April or so, they talked about three more wins of which they didn't say anything. It wasn't until after E3, where the XboxOne S and Scorpio were revealed, that people assumed that those 3 wins were for the teo MSoft machines and PS4 Neo... but for all we know one of those consoles could be powered by the x86 chip they talked last year.

We're all making assumptions, and you are like the rest of us.

For example, you are talking about Nintendo as if they were like the CIA or something like that, not allowing AMD or Nvidia talk about their machines, when that's not how it works. The reason Nvidia hasn't said anything about their Tegra X2 chip powering a new console is actually rather simple: they won't talk about design wins for a product that they still haven't officially unveiled.

It's you that said that Nvidia won't unveil the chip until the Hot Chips conference, so don't expect anything from them or Nintendo (who in turn won't talk about a console powered by a processor from another company that still hasn't revealed it either).

Lastly, and just to add more speculation, the Eurogamer article talked about the Tegra X1 chip, with only one (and they made sure to underline that), one source talking about a fan powered unit which could be there to cool a more powerful chip that everyone assumed would be the Tegra X2. But given that we're talking about dev kits, without knowing if those are early dev kits or not. And that's important because early dev kits are there only to give devs an idea of the power ballpark of the upcoming device so they can scale their projects to run on it.

There's still no reason why the final NX dev kits/console couldn't be powered by an AMD chip.

Actually, it began even before, during the N64 era, when Silicon Graphics supplied the chips for the N64, people from Silicon Graphics moved on to found ArtX, whose main purpose was to work on the next Nintendo console chip, they made the flipper for the GameCube, the rest of the story is well known!

Both articles are going off old assumptions, hence why none of them address it as news.

I firmly believe that Eurogamer has very credible sources (with actual dev kits) and that in this present time Nintendo is using Tegra X1 (with active cooling)

Yes, just this info is based on Yahoo article from May, and this are facts about that article.
https://finance.yahoo.com/news/amd-revenues-hit-weakness-semi-130735686.html

1. Article is from May.
2. Article is speculating based on design wins that AMD announced.
3. AMD did not confirm if the design win was for Nintendo. esp given that PS4 Neo and Scorpio count as new design wins.

Eurogamer article about NX is almost certain, and was confirmed buy Wall Street Journal, IGN, Kotaku, MWC and some other sites.

Not only that but EG infos are conifirmed buy WSJ and IGN for instance.

Not only that but a Nintendo patent shows that they are working detachable controller wings after Eurogamer reported this as a feature for the NX.

Now either they got very, very lucky on that guess or the report is in all likelyhood legit. IGN, MCV, and Wall Street Journal have also all cross verified by using their own sources.

Where do you see that these articles are based of Yahoo article of May???

Because they are all basically same infos based on that Yahoo speculation from May, that from some reason internet sites started to bring that Yahoo speculation just now.

You can easily see that news on both those cities are clear speculation without any confirmation or real source.

Bussiness 101: Either It works however the contract sais it works or it will work like the court sais it does. Secrecy is not illegal.

Nintendo is not the CIA, the CIA actually leaks more, lol. Kidding aside all Nintendo has to say is please don't discuss our supply deals until we formally unveil our device first.

It's just a common business courtesy. Nintendo clearly has NDAs on all things NX related. AMD breaches this protocol because they are desperate as their business is in the shitter and they need something to placate their stockholders. Nvidia is in no such position.

I'm not saying whether or not Nintendo is using Nvidia or ATI but your rationale is flawed. Stockholders aren't random forum posters. They are investors who have put their money into a company. Their is an legal obligation to notify them of company activities. They don't have to know specifcs but it does have to be truthful information.

Nvidia's SoC business is the lowest it's been in years. If they had an upcoming project they'd be required to disclose the projected revenue to stockholders. An NDA would prevent them from telling who specifically that revenue would come from. On the flipside, we know AMD provided the GPU for both the Wii and Wii U. They know detailed specifications of both GPUs. Yet we still don't know the specifics because of an NDA. Too imply that AMD breaches their NDA's is ludicrous.
