Almost most of the devices were effected by these Meltdown and Spectre flaws including the Apple devices.Both the "Spectre and Meltdown" flaws affect the performance of CPU feature called Speculative Execution which is responsible for improving speed and operate multiple operations.
Meanwhile, AMD has finally admitted that the Meltdown and Spectre security flaws found by Google Project Zero affect its chips.
Meaning the updates for the Intel computer chip flaw had its own flaws. However, there have been reports from some customers of a drop off. AWS customer Epic Games attributed a more than 20 percent spike in CPU load on a cloud server hosting games of Fortnite to the impact of the Spectre and Meltdown patches.
Intel posted a statement on its website saying, "We have received reports from a few customers of higher system reboots after applying firmware updates. We have defined additional steps through a combination of processor microcode updates and OS patches that we will make available to AMD customers and partners to further mitigate the threat". Intel might be taking the flak for the vulnerability, but AMD has snuck in an announcement that the flaw is effecting its processors as well. As per SYSmark benchmark, the overall performance impact will be 6-4% for Office Productivity, Data/Financial Analysis, and Media Creation. To date, no severe hack or data leak has been linked to the vulnerabilites. We are also working directly with data centre customers to directly discuss the issue.
Sixth generation Skylake CPUs take the biggest hit from Intel and Microsoft's mitigations, especially in system responsiveness tests which are running at a 21% performance deficit from an unpatched system.
Spectre is a name covering two different exploitation techniques known as CVE-2017-5753 or "bounds check bypass", and CVE-2017-5715 or "branch target injection".
Google says their new security patches for the processor vulnerabilities have no negative effects to performance.
As a result, Microsoft temporarily halted Windows OS updates to devices with AMD processors affected by this apparent bug, including nine updates released since January 3 with the security-only Spectre and Meltdown update among them (KB4056897).
Performance in the 7th Generation Kaby Lake H processors is said to mirror the impact in performance seen in the 8th Generation processors.
Microsoft and others in the industry were notified of the issue several months ago under a nondisclosure agreement, Terry Myerson, executive vice president of Microsoft's Windows and Devices group, noted earlier this week in an online post.
