Quote:Intel has released numbers from its own benchmarks on the impact of Meltdown/Spectre patches on Windows, and the results show an up to 21% decrease in benchmark performance for 6th-gen Intel CPUs (Sky Lake).
The Meltdown/Spectre vulnerabilities have been much more than just a blemish on Intel’s reputation. Right from the get-go, it was known that the fixes for it had the potential for a significant performance impact. The immediate follow up from major involved parties seemed to be mild, however. Many independent tests, including our own, also didn’t find any major concerns. Intel’s official stance continued to be that home users would face little impact, while the effect on enterprise would be “highly workload-dependent.”
Many were skeptical, naturally, and believed that Intel and its affected enterprise customers were downplaying the issue. As the issue entered its second week and patches had been rolled out to more customers, however, a different picture was appearing. Epic Games said the patches were responsible for a huge performance hit on its cloud service provider, which caused instability in servers for Fortnite. Microsoft, which was among those downplaying the issue before, said that they had recorded significant performance impacts on Windows 7.
