Google patches for Meltdown, Spectre not slowing down systems

NVIDIA races to patch GPU Drivers for Spectre and Meltdown

Intel produces white paper, benchmark on Meltdown, Spectre

Normally, microcode updates are distributed via new BIOS images for PCs, but "Intel realises that this can be an administrative hassle" and has made the definitions available for downloads, to Linux system administrators. AMD shares have gained almost 20 per cent in the last week as investors speculated that the chipmaker could wrest market share from Intel, whose chips were most exposed to the security flaws.

In a statement on the company's website, GM of Intel's data centre group Navin Shenoy said that this problem was specific to the Broadwell and Haswell CPUs used in client and data centres.

AMD has issued a statement to The Verge, where they said: "AMD is aware of an issue with some older generation processors following installation of a Microsoft security update that was published over the weekend".

"End users should continue to apply updates recommended by their system and operating system providers". To date, no severe hack or data leak has been linked to the vulnerabilites. As it's a huge security flaw, you're advised to install the patches as soon as they become available for your machine. AMD said yesterday the issue should be resolved shortly.

The girl's father, on returning to Pakistan on Wednesday, told the media that he would not bury her till justice was done. Zainab's parents, who were away on a pilgrimage at the time she went missing , blamed the police for their slow response.

AMD have updated their web page and clarified a bit more on speculative_execution vulnerabilities with some additional details on current state of affairs and AMD actions. Ryzen and EPYC processor microcode updates will be available this week - from both system and OS vensors.

The biggest news in cybersecurity last week was the discovery of the Meltdown and Spectre vulnerabilities in modern computer processors. In that test, every processor but one took more than a 10% hit to relative performance, with the sole exception of an Intel Core i7-6700K running Windows 7 with an HDD, which saw performance slightly improve after the patch was applied. We are working closely with them to correct an issue that paused the distribution of patches for some older AMD processors (AMD Opteron, Athlon and AMD Turion X2 Ultra families) earlier this week. Specifically, these patches come with a performance hit for Intel systems, and in the lead up to their delivery, some benchmarks showed that the potential slowdown could be as high as 30%.

Intel's testing was done using Skylake, Kaby Lake, and Coffee Lake CPUs on Windows 10, as well as Skylake machines running Windows 7. The majority of Cisco's products were not vulnerable because they are "closed systems that do not allow customers to run custom code on the device", it said.
