Microsoft Update Bricks AMD PCs

In the wake of Spectre and Meltdown, the recently discovered Intel CPU vulnerability, Microsoft has pushed out an emergency update for Windows 10, Windows 8.1, and Windows 7 devices. Almost immediately, a significant amount of users began experiencing the Blue Screen of Death on devices with specific AMD processors.



Microsoft officially acknowledged that the problems with the recent emergency update stating,

Microsoft has reports of customers with some AMD devices getting into an unbootable state after installing recent Windows operating system security updates. After investigating, Microsoft has determined that some AMD chipsets do not conform to the documentation previously provided to Microsoft to develop the Windows operating system mitigations to protect against the chipset vulnerabilities known as Spectre and Meltdown. To prevent AMD customers from getting into an unbootable state, Microsoft will temporarily pause sending the following Windows operating system updates to devices with impacted AMD processors at this time:

Performance after Microsoft’s Emergency Update

According to Intel, the newer Skylake processor architecture will not see much of a performance hit but that, “older processors could slow down more significantly due to the firmware and software updates.” They clarify further by stating that any performance slow-downs will be workload-dependent and will vary based on the actual workload and that these performance impacts will not be a blanket 5%-30% for every task.
