Source of that is a guy on Beyond3D forum that I frequent and believe me the source doesn't know jack shit. The others, some professional in chip fabrication business, grilled him and his responses got worse and worse to the point no one believed him. But this is internet, once it is out, it travels no matter what and this twitter guy "hears" that made up info from a troll. It is unsubstantiated, the guy didn't even know AMD was using TSM Co. for their SoCs.
Here we go. Oh boy. Bad yields aren't even Sony's problem, it is AMDs and all chips delivered to Sony must be up to Sony's spec, doing that frequency sustainably.
Also consoles always had worse end of the crop in terms of binning, Sony just up the game on that front and must have required higher binned chips for consoles for the first time. And the fact that Sony will receive their spec on AMD design as it is AMD side that promises yields that are up to spec, as all these must be all in the contract and if some bad yield happens it is either TSM or AMD that eat the cost, not Sony. This much is all talked on Beyond 3D forum for anyone who wants to check out. One guy is literally works there but in unrelated position, but still knows what's what.
I knew this video was coming but I still think his apology is disingenuous. Let me explain; the main thing is he is a YouTuber his work is making videos and making sure they are viewed many many times, so he is playing both fields,
first he is PC-master race truther telling the console fan boys 'the truth' that there is no beating the PCs, now his secondary income of not just reviewing (and also getting expensive presents all the time) but also selling hw is exposed to more marketing this way,
second when he produces a video that has enough views/clikcks etc. (exposed enough that Tim himself confronts him, adding a secondary wave of exposure) he is now 'realizing he is wrong and must apologize' so that he can also get the views/clicks of the other side of the equation - console fan boys (which isn't even part of his audience), this way he will get exposure to a new audience who may not follow, like, subscribed to him going forward.
1 and 2 mission done. But I'm not falling for it. Though it seems it is working on you guys, so good for him.
