Patches for Chip Flaws May Slow Down PCs

13 Enero 2018

These numbers can give you a more concrete idea of how much you'll be affected.

Other news announced during Krzanich's keynote include the launch of Intel Studios for advanced, 3D video productions; support for Intel-powered virtual reality broadcasts during the coming Olympic Winter Games; and autonomous driving technology partnerships with BMW, Nissan, Volkswagen, SAIC Motor, NavInfo, and Ferrari North America. Devices using the 7th Gen Kaby Lake-H mobile processors will be around 7 percent slower, while the performance impact on systems with the 6th Gen Skylake-S platform is approximately 8 percent. Short term, devices will need to be updated with a mix of firmware updates from the chip manufacturers and security patches from software vendors. This particular bug allows for 'Branch Target Injection' and is applicable to AMD processors.

How can we patch vulnerabilities on AMD?

Intel is facing a growing number of lawsuits, including claims from groups of consumers alleging that it misled consumers by failing to disclose the security hole and demands for compensation based on the potential slower performance of machines that have been patched.

Finally, the Intel CEO highlighted "ongoing security assurance" as the third and final part of the pledge.

"We believe our GPU hardware is immune to the reported security issue".

What systems require patching for vulnerabilities? If they're writing emails or surfing the web they're barely straining their PC's power at all, and so any slowdown is likely to be imperceptible.

When news of the flaws broke last week, the industry seemed to be caught off guard, despite the fact that they were going to publicly disclose the flaws on 9 January. The same numbers are reflected by PCMark and 3DMark benchmark.

Microsoft said it is working with AMD to resolve the issues with the Meltdown and Spectre patches as soon as possible.

Where to go from here?

Ultimately the results trend close to the 5% mark overall. This is by design to protect critical security information like usernames, passwords and encryption keys. Similarly, companies should ensure all industry required info security controls are in place and working (e.g., access control, configuration management, patch management). "To help prevent stop errors that are caused by incompatible antivirus applications, Microsoft is only offering the Windows security updates that were released on Jan. 3, 2018, to devices that are running antivirus software that is from partners who have confirmed that their software is compatible with the January 2018 Windows operating system security update".
