What strikes me the most is that the state of the art in CPU architecture is immune to Spectre and Meltdown, yet it isn't once mentioned. Makes the article sounds like Intel funded stuttering.
From what I've seen, every major high-end CPU architecture is affected, because they all rely on speculation. Of course, some low-end CPUs (such as ARM Cortex-M cores) don't have speculation, so they aren't vulnerable. But on the high-performance front, I haven't seen a credible alternative that wasn't vulnerable to speculative execution side-channels. Which one am I missing?
The Mill makes the current OOO look bad (Intel, AMD, others). It is striking to see that "experts", on this page and the writer of the article, act as if it didn't exist.
The Mill can save Intel, or destroy it, Intel decides that. The pos-x86 nears and time is running out. Intel needs a new architecture and RISC-V is only part of the answer.
