http://www.theregister.co.uk/2018/01/02 … sign_flaw/Testers have discovered a bad hardware security flaw in Intel processors that will require a major change to protected-kernel operating systems including Windows and Linux. Unfortunately the change will come with a big performance penalty. The problem was discovered months ago, but has been kept under wraps while patches were tested.\”Microsoft is expected to publicly introduce necessary changes to its Windows operating system in this month\’s Patch Tuesday: these changes were seeded to beta testers running fast-ring Windows Insider builds in November and December.Crucially, these updates to both Linux and Windows will incur a performance hit on Intel products. The effects are still being benchmarked, however we\’re looking at a ballpark figure of five to 30 per cent slow down, depending on the task and the processor model. More recent Intel chips have features to reduce the performance hit.\”This is worse than Apple\’s battery performance slowdown! Time for a class-action lawsuit – I want 5-30% of my money back on the price of the Intel processor!More: https://www.newscientist.com/article/co … -chip-bug/
Rumor is now that the old AMD crapdozer CPUs are actually faster than it\’s intel counterpart post patch.
