    Microsoft and Intel have shared more information on the performance impact of the patches released for the recently disclosed attack methods known as Spectre and Meltdown.

    The Spectre and Meltdown exploits work on systems using CPUs from Intel, AMD and ARM, and they allow malicious applications to bypass memory isolation mechanisms and access passwords, photos, documents, emails, and other sensitive information. Patches and workarounds have been released by both hardware and software vendors, but they may introduce significant performance penalties.

    Intel has insisted that average computer users – owners of typical home and business PCs – should not see any significant impact on performance during common tasks, such as reading emails, viewing photos or writing documents. Benchmark tests conducted by the company using SYSmark 2014 showed an impact of 6 percent or less for 8th Generation Core platforms with solid state storage.

    All but two of currently supported Intel processors are said to be affected by the Spectre and Meltdown vulnerabilities. However, a technology called PCID (Process-Context Identifiers), which is present in newer processors, should lessen impact on performance.

    wow, they are considering latest specs with SSD for impact analysis.

    What will happen with my 1st Generation non-SSD, crawl...:tear:
