Here's how Intel's Spectre and Meltdown patch affects server CPUs

MICROSOFTWindows 10 users have been warned to stay away from a fake Meltdown and Spectre patch

Intel shares ended higher in the United States, despite the latest update from the tech firm that it's patches to mitigate the Spectre and Meltdown flaws are adversely affecting its newer processing chips, too. Intel has been looking into the issue, and has found that it happens in configurations featuring Ivy Bridge, Sandy Bridge, Skylake, and Kaby Lake processors.

"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.

In a news update which clarified that firmware updates have now been issued for 90% of Intel's processors introduced in the past five years, as planned, Intel restated that some customers have reported "more frequent reboots" on Haswell and Broadwell (4th and 5th-gen CPUs) powered PCs after the patch had been applied. Intel says that the existing updates continue to provide protection against the flaws even if they might wreck reliability for some folks. It intends to ship a beta microcode to system builders next week.

Infosec firm Bridgeway has found that only four per cent of enterprise smartphones and tablets in the United Kingdom have been patched against Meltdown and Spectre, the chip vulnerabilities that were disclosed earlier this month.

Going on two weeks since the reveal of Meltdown and Spectre, are you all patched up? Intel's stress tests - which, in this case, means a 100% write case - showed an 18% decrease in performance, though switching to a 70/30 read/write model improved things drastically, bringing the performance hit up to 2%.

On Tuesday, as part of its quarterly patch update, Oracle released fixes for 237 flaws across its products, including its first batch of Spectre and Meltdown fixes. "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".

Intel has also followed up its initial desktop performance metrics with benchmarks for data center.

Patching: Performance ImpactTested: Server platforms running two-socket Intel Xeon Scalable systems (code-named Skylake), which is Intel's latest server microarchitecture. "For example, there are other mitigations options that could yield less impact".
