Like I said, AMD was unique on Meltdown in that their branch predictor uses a neural-net based approach that is difficult to train to follow a specific path. It affected everyone else in the industry - Intel, IBM, ARM, Oracle, everyone.
- Retric 7y agoIf that’s what you meant then saying ‘Meltdown and Spectre affected literally everyone in the industry’ was literally false. Perhaps you could say almost everyone else in the industry in the future. As to being lucky, I have no idea what their internal process is or what they considered. But luck seems like an odd way to talk about such things.
- tomp 7y agoIsn't the reason that AMD isn't affected, that they don't prefetch / cache pages before checking instruction's access privileges?
- Eopia 7y agoI think you are confusing Meltdown with Spectre V2.
- NicoJuicy 7y agoSo researchers aren't checking AMD. A bit later, AMD was uniquely not affected. But they were investigated, yes? Seems like you like Intel more than AMD. No problems with that, I'm the other way around :)
