Arthur T Knackerbracket has found the following story:

In 2015, Microsoft senior engineer Dan Luu forecast a bountiful harvest of chip bugs in the years ahead.

"We've seen at least two serious bugs in Intel CPUs in the last quarter, and it's almost certain there are more bugs lurking," he wrote. "There was a time when a CPU family might only have one bug per year, with serious bugs happening once every few years, or even once a decade, but we've moved past that."

Thanks to growing chip complexity, compounded by hardware virtualization, and reduced design validation efforts, Luu argued, the incidence of hardware problems could be expected to increase.

This month's Meltdown and Spectre security flaws that affect chip designs from AMD, Arm, and Intel to varying degrees support that claim. But there are many other examples.

    The reason to distinguish between them for the average person is the performance impact of the mitigation. Everyone expects a constant stream of bugs/vulns these days anyway, but not that patching for them will slow everything down to half speed or whatever. That is where intel has the main problem (according to what I've read).
