Separately, technology website The Register reported, citing a document in Oracle's customers-only portal, that certain versions of Oracle Solaris on SPARCv9 are affected by one of the chip flaws, named Spectre, and the company was working on a security patch for it.
The lawsuits aim to acquire compensation from AMD for the damage it has caused with its misleading statements about the supposed safety of its CPUs against the Spectre and Meltdown security flaws. "But we have more work to do". Thankfully, Intel VP Navin Shenoy said that they're close to identifying the problem's root issue. "In parallel, we will be providing beta microcode to vendors for validation by next week", Shenoy said.
Last week, Intel shared initial benchmarks for its Spectre and Meltdown patch for recent consumer-focused Core i7 CPUs. In a new blog post published yesterday, the exec added that recent patches for the newer Ivy Bridge, Sandy Bridge, Skylake, and Kaby Lake architectures can cause similar reboot issues (via Engadget).
While Intel says it has patched the exploits in 90 percent of the processors it has introduced in the last five years, it's clear there are still reliability issues affecting those processors.
In fact, many vendors are continuing to develop and distribute patches for Spectre and Meltdown.
On Wednesday, the chipmaker confirmed that the security patches are causing higher than expected reboot for computers with newer chips.
The impact appears to be minimal in most cases, with Intel seeing a 0-2 percent performance on industry standard measures of integer and floating point throughput, Linkpack, Stream, server-side Java, and energy efficiency benchmarks.
"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 says.
With the FlexibleIO benchmarks, stressing the CPU fully during writes saw an 18 percent decrease in performance, because there was no headroom for processor utilisation, Intel said.
We also see a 4% impact to performance in an online transaction processing benchmark, so things look good there as well.
Tests were conducted by the company on Intel's Skylake two-socket Xeon processor systems, its latest server microarchitecture.
