Intel Says 'Partitions' in New Chips Will Correct the Design Flaw that Created Spectre and Meltdown
Intel Says 'Partitions' in New Chips Will Correct the Design Flaw that Created Spectre and Meltdown
Published on March 15, 2018 at 10:10PM
Intel said on Thursday it is introducing hardware protections against the Spectre CPU flaw that was discovered last year. From a report: Starting with the Cascade Lake version of its Xeon server processors later this year, Intel will incorporate "protective walls" in its hardware that prevent malicious hackers from using speculative execution techniques to steal private information from the secure part of the processor. These fixes will also ship with the PC version of the Cascade Lake chips, but the tech industry has been much more concerned about the effect of these design flaws on server processors running in data centers and cloud vendors. The new fixes allow Intel to still benefit from the performance advantages of speculative execution -- in which a processor guesses which upcoming instructions it will need to execute in order to speed things up -- without the security risks. The hardware changes address Variants 2 and 3 of the Spectre and Meltdown issues first disclosed in early January, and software fixes should continue to address Variant 1, Intel said.
