Today we're taking a look at the impact addressing the Spectre 'Variant 4' CPU flaw has on Intel's 8th-gen Core CPUs. The initial Meltdown and Spectre patches didn't take care of everything and just recently Intel and Microsoft have rolled out updates to address Variant 4 a.k.a. 'Speculative Store Bypass'.
Following up to our initial testing of the Meltdown patch for Windows 10, today we're looking deeper into the matter by testing a patched desktop system, by addressing the two now famous security flaws, Meltdown and Spectre, by applying the OS-level patch and a firmware update, more precisely a motherboard BIOS update.
The IT world was caught by surprise this week when Meltdown and Spectre hardware flaws were disclosed. With OS patches coming in, including an emergency fix for Windows 10, we've conducted a set of tests in the last 12 hours to see what impact this update has on performance for desktop users, if any at all.
