Microsoft expects most people using Windows 7 and Windows 8 on chips that are from 2015 or older will notice performance degradations, Terry Myerson, executive vice president for Microsoft's Windows and Devices Group, wrote in a. The company did not publish specific performance benchmarks to back up the claims.
Essentially, the vulnerabilities affect the kernel of the chips and could allow an attacker to read information that should otherwise be inaccessible. Now that they are known about though, a fix is incredibly important and we now have those patches rolling out.
"We're performing our own sets of benchmarks and will publish them when complete, but I also want to note that we are simultaneously working on further refining our work to tune performance", he said.
The Spectre and Meltdown vulnerabilities found in modern processing chips currently have the industry in a frenzy to patch the holes. "As a result, we expect some workloads may have a larger impact than others".
Cisco also said it was looking for possible problems in close to 30 more products, which included routers and switches.
However, while there has been only minimal performance impact on the newer versions of Microsoft running on newer laptops with the latest model of processing chips, older versions and models aren't faring so well.
Apple has released iOS 11.2.2 with a security update for Safari that serves to guard against the Spectre bug. After some period of delay, Microsoft has expressed themselves about the upcoming changes, and the fixes that are about to be deployed.
Nvidia's software developers will be, like AMD, providing collaborative help to OS vendors to strengthen mitigations for affected CPUs that could be affected by For GPZ Variant 1 and 2 (Spectre).
We get the impression this is not the last of the bad news from Intel.
