Upcoming CPU patches could cause performance issues

Microsoft has reported performance issues with computers and servers resulting from security patches for vulnerabilities in hardware chips from Intel and AMD.

In response to queries about the vulnerabilities affecting Radeon GPUs, Papermaster said that the chip architecture does not use speculative execution, which is the basis for the processor vulnerabilities, so there is no impact at all.

"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", Microsoft said in its statement. As of now, the software giant has halted distribution of security updates for some older AMD-powered machines. In other developments, Microsoft also warned that some computers powered by older processors probably won't work as well as they once did after the antidotes to Spectre and Meltdown are installed. While companies are busy patching the issue Huang is certain that Nvidia GPUs are not affected by this bug and that the company will not be patching anything.

Meltdown and Spectre patches for the Linux and Microsoft platforms are already available.

Meltdown removes the barrier between user applications and sensitive parts of the operating system while Spectre, which is also reportedly found in some AMD and ARM processors, can trick vulnerable applications into leaking the contents of their memory. The impact on the performance could be up to 6 percent when office productivity and media creation software would be rolled out.

Security researchers identified the problem last year, shared details with chip manufacturers last summer, and then made a public announcement January 3.

AMD will begin issuing optional updates to guard against Spectre vulnerabilities later this week, the company said in a new blog post.

The firm added that workloads that are graphic and compute intensive (such as gaming and financial analysis respectively) will impact performance very minimally. The SEC could even step in, and haven't confirmed or denied if they are investigating the Intel CEO.

A Google spokesman said the company is set to announce its performance expectations for Android's chip flaw remedy as soon as Wednesday.
