Intel Chip Design Flaw

Not sure yet how much of this is fear mongering.  The upshot is that a design flaw in the chip architecture allows code to be able access protected kernel memory.  The article above is stating that it might cause a 30% degradation of speed.  If true this is very very large problem.  The article states that it affects all Intel chips over the last decade.

If it's true and accurate, I'm really happy I went with a Ryzen CPU with my current computer. This could be pretty bad news.

To update on this topc :

2 flaws, Meltdown and Spectre.
Meltdown is Intel only, but can be mostly mitigated by OS patches which have been rolling out already.
Spectre concernes EVERY chipset made in the last ~10 years (basically any chip which has branch prediction) and has no global possible fix, just possible mitigation software by software.

Pretty bad times :/
