Intel's Meltdown and Spectre patches are causing reboot issues in older chips

The first two are known as Spectre and the third as Meltdown.

AMD's shares have gained almost 20 percent since the flaws were made public on January 3 as investors speculated that it could wrest market share from Intel, which is most exposed to the flaws because it is vulnerable to all three variants.

Since the major processor-based Spectre and Meltdown vulnerabilities came to light earlier this month, technology companies have been working to develop and deploy patches across millions, if not billions, of devices.

The company's Project Zero team discovered the chip vulnerabilities past year as it outlined in a blog post last week.

The real headache for Google turned out to be Spectre Variant 2. And thanks to the efforts of hundreds of engineers, no one has apparently noticed because the fixes haven't slowed down or degraded popular services like Google search, Google Drive, and Gmail.

Be warned: Intel's recent maintenance update - created to address the terrifying Meltdown and Spectre vulnerabilities - could affect the performance of some of its older Broadwell and Haswell CPUs.

Meltdown, Google explains, "breaks the most fundamental isolation between user applications and the operating system".

But Variant 2 (Spectre) was a different story. Unlike other proposed methods, it was fairly easy to deploy thanks to its status as an on-the-fly external binary modification technique rather than a processor tweak, and did not cause any noticeable difference in performance for clients or their users. "As for our driver software, we are providing updates to help mitigate the CPU security issue".

Aside from Nvidia, Intel and Microsoft has also released their respective statements on the issue of the Meltdown and Spectre.

For some time, Google says "it appeared that disabling the vulnerable CPU features would be the only option for protecting all our workloads against Variant 2". If your system is affected, the program will offer further information on how to protect your computer. Devices using the 7th Gen Kaby Lake-H mobile processors will be around 7% slower, while the performance impact on systems with the 6th Gen Skylake-S platform is estimated to be around 8%.
