Slowdown lowdown: In a blog post, Microsoft’s head of Windows says older machines, particularly ones running Windows 7 or 8 on Intel’s Haswell chips, will see performance fall after updates to protect against Spectre. Computers running Windows 10 on the same chips will also see some decrease in performance. Newer chips will be largely unaffected.
AMD users wait: The Verge says Microsoft has hit pause on issuing security updates for AMD chips after reports that fixes prevented computers from booting. Microsoft blamed AMD’s documentation for the issue.
More to come: Microsoft’s announcement may force other companies, like Apple and Google, to be more forthcoming about how security updates affect performance of Macs, iPhones, and Android devices.
