Advanced Micro Devices Inc said on Thursday its microprocessors are susceptible to both variants of the Spectre security flaw, days after saying its risk for one of them was “near zero”. In a subsequent statement Thursday, AMD said there was “no change” to its position on the susceptibility of its chips to Spectre, but shares fell as much as 4.0 percent after the first AMD announcement.

Apple is the only PC or smartphone vendor to have full control over the user experience it provides to its customers, thanks to its positioning as an integrated platform vendor. This is a key–often overlooked–advantage for the company that is driving customer satisfaction and trust as well as attracting serious attention from the enterprise at a time when Google’s Android is doing neither one.

Intel Corp on Thursday said that recently issued patches for flaws in its chips could cause computers using its older Broadwell and Haswell processors to reboot more often than normal and that Intel may need to issue updates to fix the buggy patches.
