Intel updates its microcode due to security flaws
-
These are 3 vulnerabilities related to the VT-d virtualization repertoire, a failure in the isolation of shared resources and a failure related to the leakage of information in Atoms.

This is what happens when you keep using the same architecture as the Pentium Pro. It's been almost 30 years of beating around the bush and now they're discovering the cake. If Intel had taken NetBurst more seriously instead of making a mess in a desperate attempt to compete with the Athlon XP, this wouldn't be happening or would be happening to a much lesser extent. The only option left is to completely redo their architecture and let P6 rest in peace once and for all. Until then, their processors will be getting slower and slower. -
@Gallina It's a bit of a stretch to say that the latest Cores are based on the P6. It's like saying that any current PC is based on the ENIAC because, after all, they are electronic computers. Intel tends to make evolutionary changes with each step (except as you rightly said with Netburst and other more esoteric architectures like Itanium) versus AMD's "revolutionary" changes which, incidentally, have made them stumble on several occasions.
And the proof is that the older processors from the Core 2 generation (I can't remember exactly in which generation it happens), the patches for these flaws do not penalize performance as they do with most AMD processors.
