Remember the Meltdown and Spectre flaws that affect all computers and mobile phones out there? "But we have more work to do". As you may know, the company said that it would issue firmware updates for all its processors from the past five years by the end of the month, but the company already acknowledged some issues last week.

"Intel recommends that these partners, at their discretion, continue development and release of updates with existing microcode to provide protection against these exploits, understanding that the current versions may introduce issues such as reboot in some configurations", the company wrote.

"We have reproduced these issues internally and are making progress toward identifying the root cause", Intel's executive vice president and general manager of the Data Center Group Navin Shenoy.

Microsoft started releasing emergency patches addressing serious processor chips flaws namely Meltdown and Spectre. As for the Spectre and Meltdown patches, more benchmarks will likely be coming down the pipeline soon, so stay tuned.

Last week, AMD put out a security update confirming that its processors are vulnerable to Spectre variant 1, which will be contained by operating system patches.

A new Routines feature also allows you to automate a series of customisable actions using a single voice command of your choosing. For example, if you bank with the NAB or Westpac, Alexa can check your bank balance for you.


On Wednesday, the chipmaker confirmed that the security patches are causing higher than expected reboot for computers with newer chips.

Benchmarks measuring integer and floating point throughput, as well as LINpack runs and STREAM memory performance tests and server-side Java, showed negligible difference between patched and unpatched systems, Intel noted. "Generally speaking, the workloads that incorporate a larger number of user/kernel privilege changes and spend a significant amount of time in privileged mode will be more adversely impacted", he said, which pretty much echoes what we've heard before.

Intel issued the update as part of a broader update on the performance impact of the patches on data center workloads.

Advanced Micro Devices (AMD) is not as insulated from the recent central processing unit (CPU) security flaw debacle, as the CPU manufacturer is now facing two class action lawsuits like its competitor Intel.
