Microsoft Spectre v1 Patches Borking Older AMD Systems

Microsoft said it had received complaints from AMD customers that their machines stopped loading the Start menu or taskbar after installing Windows operating system security updates.

The performance impacts are felt more significantly in older operating systems because Windows requires more user-kernel transitions to accommodate legacy design decisions, such as all font rendering taking place in the kernel, Myerson wrote.

With Windows 8 and Windows 7 on older silicon (2015-era PCs with Haswell or older CPU), we expect most users to notice a decrease in system performance. This is why you want to be careful to evaluate the risk of untrusted code for each Windows Server instance, and balance the security versus performance tradeoff for your environment.

Microsoft didn't release specific benchmark results, or reveal how it generated those numbers.

AMD processors are technically not affected by the Meltdown vulnerability, and the company has been maintaining that it also immune to the threat imposed by Spectre. Older personal computers, as well as those running the Windows Server operating system, can expect "more significant slowdowns", according to Microsoft. The company doesn't expect most users to notice this slowdown on modern hardware because we're talking about milliseconds, but the performance degradation should be more apparent on older hardware.

However, Pitt's bid proved to be unsuccessful after an unidentified individual outbid him to claim the prize for $160,000. Brad Pitt is serious about " Game of Thrones " fandom - at least when there's philanthropy involved.

That's a nightmare scenario, because the flaws - named Meltdown and Spectre (because vulnerabilities have cool names nowadays) - are due to how the chips are designed, and you can't fix it with an update. However, Microsoft's announcement added an important clarification.

Microsoft says firmware updates are only required to protect against what's being described as Spectre variant 2. As its name suggests, the performance.now () method is used to gauge the responsiveness in web applications by precisely measuring time intervals, a requirement of a successful Meltdown and Spectre attack. But the TL;DR is simple; the fixes impact system performance.

Another important clarification by Microsoft is that the firmware update ("silicon microcode") distributions are decided by the PC or server original equipment manufacturers (OEMs). Intel released its own performance information, though it showed just a slight impact for its 8th-generation Core chips. Surface will be updated through Windows Update starting today. The remaining updates will be coming "soon".

In early December we began distributing Intel firmware updates to our OEM partners. We do recommend the AMD owners to not install any updates until the issue is resolved.
