For GPZ Variant 2, AMD says that while its architectures make it "difficult to exploit", it is still working with OS software developers and on issuing a microcode update. They will follow this up with updates available for previous generation products over the coming weeks.
This stood in contrast to AMD's original response on January 3 to the Spectre and Meltdown vulnerabilities when it blogged that there was currently "near-zero risk" to its processors from vulnerabilities associated with the Spectre and Meltdown issues.
Following the Wall Street Journal report, Intel issued a statement by Nevin Shenoy, general manager of its datacentre group, confirming that Intel had received reports from "a few customers" of higher system reboots after applying firmware updates. Intel has continually told users to update their systems when prompted, though these patches aren't solving the problem.
Cisco said it is also looking for problems in nearly 30 other products, including switches and routers. It also insisted that it has yet to receive any information that the Spectre/Meltdown flaw has been used to obtain customer data, but it's probably for the best to install the fix when you get it anyway. AMD said yesterday the issue should be resolved shortly. As a result, microcode updates and further OS patches will be on the way to mitigate the issue. As per SYSmark benchmark, the overall performance impact will be 6-4% for Office Productivity, Data/Financial Analysis, and Media Creation. If they don't, their systems will suffer from the system slowdown that comes with the Meltdown patches without improving security. Those running Windows 10 systems on newer CPUs would see minimal impact, it said.
But the reboot bug indicates that the flaw in the chips may be so fundamental that Intel may have a tougher time fixing it than it expected.
It's been a rough week for chip manufacturers and operating system companies.
The exec said that the hardware giant is working on a solution to this problem.
Apple claims that performance of Macs, iPhones and iPads is largely unaffected by the patches, stating "our testing with public benchmarks has shown that the changes in the December 2017 updates resulted in no measurable reduction in the performance of macOS and iOS as measured by the GeekBench 4 benchmark, or in common Web browsing benchmarks".
