Computers will run up to 30% slower once operating systems are patched to fix the chip-level bug.
(CCM) — A gaping security flaw has been discovered in the fundamental design of Intel microprocessors, according to a report in The Register.
In order to fix the bug, the Windows and Linux kernels — key parts of these operating systems — will have to be rewritten. The bad news is that the changes to the operating system kernels will involve a significant performance hit. This will vary according to task and processor model, but the bottom line is that computers powered by the affected Intel chips are likely to run between 5% and 30% slower once the security fix has been installed, according to the report. Apple's 64-bit macOS will be similarly affected.
Patches for the Linux kernel are available now, and similar fixes for Windows are currently being tested and are likely to be rolled out in an upcoming Patch Tuesday. It is not known when Apple plans to issue a fix for its Mac computers.
